City of Lancaster

A city address is usually permitted by the city, not the county — but not always, and some authorities keep building and hand electrical to someone else. Getting this wrong costs the whole submittal, because every requirement below belongs to whoever actually holds jurisdiction. Check the overlays in the same pass: an HOA, a historic district, a windstorm certification or a system-size cap can reshape the design, and all of them are cheaper to find now than after the array is laid out.

• Is this authority the AHJ for residential solar at this address? Yes. The City of Lancaster is the building and electrical AHJ for residential rooftop PV inside the city limits. Lancaster is an incorporated city inside Los Angeles County; LA County Public Works Building & Safety has no role here. Ordinance No. 1139 adopts the 2025 California codes 'as the Lancaster Codes for Buildings and Construction' and LMC 15.04.020 defines 'Building Official' as 'the Building Official of the City of Lancaster' and 'Jurisdiction' as 'the City of Lancaster'. The FIRE code AHJ is the Los Angeles County Fire Department, by contract. 95% · adopting ordinance (Ord. No. 1139, Title 15 LMC)
• What does this authority permit itself, and what does it delegate? Both, in one place. Lancaster Building & Safety (in the Community Development department, plan check under City Engineering) permits and inspects building, electrical, mechanical and plumbing work itself. For a residential rooftop PV retrofit the city's own bulletin says only an ELECTRICAL permit is required, and that 'Planning review IS NOT required' and 'Fire Department approval IS NOT required' at 10 kW or less. What is delegated OUT: the fire code is enforced by the Los Angeles County Fire Department under contract, and LACoFD retains energy storage systems and its own disconnect-placarding inspection; the general plan-check page directs applicants to 'make a separate submittal to the Los Angeles County Fire Department for review of the codes they enforce' (661) 949-6319. Utility interconnection is not the city's business at all - SCE handles it. 85% · city solar bulletin (SPV Toolkit Doc #1) + plan check page + fire department page
• Is a permit required for a residential rooftop PV system? Yes. LMC 17.08.300.B: 'The applicant shall submit for and receive approval of a building permit prior to installation of any solar energy system.' The SPV Toolkit adds that an electrical permit is the permit actually required for a PV system of 10 kW or less. Nothing in the city's 'work that does not require a permit' list exempts solar. 95% · zoning ordinance LMC 17.08.300 (Municode, codified through Ord. 1142)
• Is there a separate electrical permit, or is it combined? Combined in practice for a retrofit. The city's solar bulletin lists exactly one approval - 'a) Electrical Permit' - covering the whole PV installation; the citywide fee schedule bills it as a single 'SOLAR PHOTOVOLTAIC PLAN CHECK/INSPECTION' line rather than as separate building and electrical permits. Where a project also involves other trades, LMC 15.04.080/109.2 contemplates separate building, electrical, mechanical and plumbing fees. 80% · city solar bulletin + citywide fee schedule effective 10-01-2025
• Is a HOA or architectural approval required first? No. Approval is administrative and non-discretionary under LMC 15.45 (adopted to comply with the Solar Rights Act and AB 2188), and Civil Code 714 voids HOA restrictions that significantly increase cost or decrease efficiency. Worth noting a drafting quirk: the parallel EV-charging chapter 15.46.030.D says in terms 'Approval is not subject to Association approval', and the Fee Schedules page repeats that note for EVSE - the solar chapter contains no equivalent sentence, but Gov. Code 65850.5 forbids conditioning a solar permit on HOA approval regardless. 80% · adopting ordinance LMC Chapter 15.45 (and 15.46.030.D by contrast)
• Is there a historic-district review? No. Lancaster has no historic-preservation ordinance, historic district or design-review body that would touch a rooftop PV retrofit. A full-code search of the Lancaster Municipal Code for 'historic preservation' returns three hits, all incidental - two definitions inside the flood-damage-prevention article of Chapter 17.40 and a variance-procedures cross-reference. There is no historic overlay in the Title 17 chapter list. The only 'historic' item in Title 15 is Chapter 15.30 adopting the 2025 California Historical Building Code, which applies to designated qualified historical buildings, not to a district review. 85% · full-text search of the Lancaster Municipal Code (Municode, Supp. 10-25)
• Is a wind or windstorm certification required? No. There is no wind or windstorm certification requirement - that is a Texas/TDI concept with no California equivalent. What Lancaster does impose is a design wind speed: Design & Submittal Requirements gives 'Basic Wind Speed: All Exposure Category C - Risk Category I: 90 mph; II: 95 mph; III: 100 mph; IV: 105 mph', or location-specific speeds from the ASCE hazard tool. For a flush-mounted array the wind check is discharged by the Structural Criteria anchor-fastener test (5/16" lag screws with 2.5" embedment, or the manufacturer's guidelines). 88% · submittal-requirements handout (DWP0537 01-26)
• Is a Specific Use Permit or Council approval ever required? Not for a roof-mounted residential system - LMC 15.45 makes eligible small residential rooftop solar administrative and non-discretionary. A conditional use permit IS required for a solar farm: LMC 17.08.290.B, 'As allowed only on properties zoned RR-2.5, the applicant shall submit for and receive approval of a conditional use permit and building permit prior to construction of a solar farm.' Council approval is not required for either. 90% · zoning ordinance LMC 17.08.290 + LMC 15.45
• Is there a system-size cap on residential generation? No cap on residential generation as such. The 10 kW AC (or 30 kW thermal) figure in LMC 15.45.020 is the eligibility limit for EXPEDITED review, not a limit on system size; the same 10 kW is the scope limit of the city's Standard Plans, which also require a single-phase 120/240 V service with a busbar rating of 225 A or less. The fee schedule bands residential roof-mounted at 'under 25 kW', implying larger residential systems are permitted at a different fee. Above that, SCE's NEM/NBT interconnection track under Rule 21 runs to 1 MW. Separately, LMC 17.08.305 imposes a generation MINIMUM on new production homes (see q under Installation), not a maximum. 80% · adopting ordinance LMC 15.45.020 + fee schedule + SCE Rule 21

Several authorities require the electrical permit to be pulled by a licensed electrician, or require the contractor to be registered with them BEFORE applying. Registration is not same-day. This is second on the list rather than fourth because it is the step most likely to stop the job before the drawings matter.

• Who is allowed to pull the electrical permit? Licensed electrician / licensed contractor, or the resident owner-builder. LMC 15.12.060.A: 'No permit shall be issued to any person to do or cause to be done any electrical work regulated by this code unless such person is a duly licensed contractor as required by Chapter 9, Division 3 commencing with Section 7000 of the Business and Professions Code'. 15.12.060.B carves out the bona fide owner of a single-family dwelling they occupy (and a duplex where the owner occupies one unit); an owner or property manager may NOT pull one for a rental except that duplex case. The FAQ adds that an authorised agent may apply with a Letter of Authorization on file. 92% · adopting ordinance LMC 15.12.060 (Ord. 1139)
• Must the contractor be registered with this authority before applying? Yes - a city business licence, not a trade registration. Building & Safety FAQ: 'Contractors must have a valid City business license and a valid Workers' Compensation certificate, if applicable, on file before a permit can be issued.' Symbium is stated to verify contractor and business licences automatically for instant permits. Separately, special inspectors 'shall be registered and approved by the Chief Building Official prior to performing any work in the City of Lancaster'. 85% · department FAQ page
• Is a homeowner permitted to self-install and self-permit? Yes, for a dwelling the owner actually lives in. LMC 15.12.060.B permits an owner-builder electrical permit for 'a single-family dwelling used exclusively for living purposes ... in the event that such person is the bonafide owner of such dwelling ... and the same is occupied and used exclusively by ... said owner', and for a duplex where the owner occupies one unit. Not available for rental or lease property. The city publishes an Owner Builder Verification Form. 90% · adopting ordinance LMC 15.12.060.B + Owner Builder Verification Form

Almost everywhere wants a site plan, a one-line or three-line electrical diagram, equipment cut sheets with listings, and a structural attachment detail. Build it against the published checklist rather than the last jurisdiction you worked in — the checklist is what the reviewer marks against.

• What documents make up a complete submittal? Per SPV Toolkit Document #1: (a) completed permit application form; (b) the Eligibility Checklist for expedited permitting (Toolkit Doc #2); (c) a completed Standard Electrical Plan - Toolkit Doc #3 for central/string inverters or Doc #4 for microinverters/AC modules - or, if not using them, an electrical plan showing location of main service or utility disconnect, module/string counts, inverter and combiner make and model, one-line diagram, grounding/bonding, conductor and conduit type/size/count, batteries and their venting if any, equipment cut sheets, labelling per CEC 690 and 705, and a site diagram with panel arrangement, north arrow, lot dimensions and distances from property lines to adjacent buildings; (d) a roof plan showing roof layout, PV panels, approximate roof access point, code-compliant access pathways, PV system fire classification and the locations of all required labels and markings; (e) completed Structural Criteria (Toolkit Doc #5), or engineer-stamped structural drawings and calculations if the system does not qualify. Where the Symbium instant route is used the questionnaire replaces the paper package. 85% · published checklist (SPV Toolkit Doc #1 and #2)
• How many copies, and in what format? Electronic PDF through the Accela Citizen Access portal - no paper copies for residential solar. The current Design & Submittal Requirements sheet (DWP0537, dated 01-26): 'An electronic, in PDF format, complete set of drawings, including calculations, reports and other documentation as may be required. Submit drawings as a single PDF print file for smaller submittals. Larger drawing submittals may have a separate file for each discipline. Calculations, reports, and other documentation may be in separate files. File size is limited to 32MB.' Paper plans, if submitted at all, 'must be legible, blue-line copies (no ink), fully dimensioned, and drawn to scale (minimum 1/8" scale, 1/4" recommended)'. LMC 15.45.020 defines 'Electronic submittal' for solar as 'a PDF uploaded through the online permitting portal'. 90% · department submittal-requirements handout (DWP0537 01-26)
• Is a site plan required, and what must it show? Yes. Design & Submittal Requirements: 'A site plan is required for all submittals.' For solar specifically the SPV Toolkit requires a site diagram showing 'the arrangement of panels on the roof or ground, north arrow, lot dimensions and the distance from property lines to adjacent buildings/structures (existing and proposed)', plus a separate roof plan showing roof layout, PV panels, approximate location of roof access point, location of code-compliant access pathways, PV system fire classification, and the locations of all required labels and markings. 88% · submittal-requirements handout + SPV Toolkit Doc #1
• Is a one-line / three-line diagram required? Yes. The SPV Toolkit requires a 'One-line diagram of system' in the electrical plan, and the Standard Plans (Toolkit Docs #3 and #4) are themselves built around completed single-line diagrams (SINGLE-LINE DIAGRAM #1 / #2 sheets with tagged components). No three-line diagram is required for a one- or two-family dwelling. 90% · published checklist (SPV Toolkit Doc #1 and #3/#4)
• Are string and conductor calculations required? Yes. The Standard Plan requires the applicant to fill in module Voc/Isc, maximum system DC voltage, maximum power-point current and voltage, conductor type (USE-2 or PV-Wire), size, number of conductors and conduit type for each circuit segment, source-circuit OCPD sizing, and the point-of-connection/busbar 120% check. If the simplified plan's ambient-temperature or configuration limits are exceeded the applicant must use the Comprehensive Standard Plan. If not using a standard plan, the electrical plan must 'specify grounding/bonding, conductor type and size, conduit type and size and number of conductors in each section of conduit'. 88% · SPV Toolkit Doc #3 (Standard Plan) worksheets
• Is a structural PE stamp required, and at what threshold? Threshold is the city's own Structural Criteria worksheet (SPV Toolkit Doc #5), not a kW or psf number alone. A flush-mounted array needs NO engineer if every item is YES: single roof with no reroof overlay; roof structurally sound with no sagging; modules parallel to the roof plane with a 2"-10" gap; no overhang of ridges, hips, gable ends or eaves; modules plus supports no more than 4 psf for PV (5 psf solar thermal); array covers no more than half the total roof area; manufacturer's project-specific racking worksheets attached; roof plan of module and anchor layout attached; proposed anchor horizontal spacing less than the Table 1 value for the measured roof slope and rafter spacing; and 5/16" lag screws with 2.5" embedment into the rafter, or anchors meeting the manufacturer's guidelines. 'One or more items are checked NO. Attach project-specific drawings and calculations stamped and signed by a California-licensed Civil or Structural Engineer.' 90% · SPV Toolkit Doc #5, Structural Criteria for Residential Rooftop Solar
• Is an electrical PE stamp required, and at what threshold? No electrical PE stamp for one- and two-family rooftop PV. The city's Policy on Building Plan Signatures applies the B&P Code 5537/6737 exemptions - an unlicensed person may prepare plans for a single-family dwelling of not more than two storeys and basement, or up to four dwelling units - and the plan check page repeats this. The Standard Plan is signed by the 'Contractor/Engineer' with licence number and class (a C-10 or C-46 signature), not stamped by a PE. 80% · Building Plan Signature/Stamp policy + plan check page

Most authorities now take the whole application through a portal, and several states cap or constrain what a residential solar permit may cost. Check whether plan check is billed separately before you quote the job.

• Which permit portal does this authority use? Two portals, and for residential solar you must use the second. Accela Citizen Access at https://aca.accela.com/lancaster/ is the general permit and inspection portal. Symbium is the expedited/instant residential permitting system, embedded on the city's Instant Permits page (iframe symbium.com/embed-search/?jurisdiction=lancaster): 'Symbium has been available for roof-mounted Residential Solar permits since November 1, 2024' and from September 1, 2025 also carries residential reroof and HVAC. Symbium is a SolarAPP+ alternative accepted under Gov. Code 65850.52 (SB 379). 92% · permits page + Instant Permits page (Symbium embed)
• Can the whole application be completed online? Yes. For a qualifying roof-mounted residential solar or battery-storage project the whole thing is online and automatic: 'You don't have to leave Symbium to submit and pay for your permit application. Using Symbium, your permit will be issued automatically, without manual review or an in-person visit. Symbium even automatically verifies your contractor's and business licenses.' For anything that does not auto-issue, 'please contact Building & Safety staff at permits@cityoflancasterca.gov'. The Building & Safety page adds that 'Most permit requests, fee payments, and inspections can be processed online through the Accela Citizen Access (ACA) Portal, including all residential permits, solar, water heaters, mechanical/electrical/plumbing permits, and signs.' 92% · Instant Permits page + Building & Safety page
• What does a residential solar permit cost? $256 for a residential roof-mounted system under 25 kW. Citywide Fee Schedule effective October 1, 2025: 'SOLAR PHOTOVOLTAIC PLAN CHECK/INSPECTION - Residential Roof Mounted <25 KW $256; Commercial Roof Mounted Each 100 KW $950; Utility Scale 1-5 MW $8,795; 6-25 MW $12,422; 26-50 MW $16,299.' This supersedes the $234 total ($199 plan check/inspection + $27 travel and documentation + $8 permit issuance) still printed in the SPV Toolkit. The 2017 toolkit also states 'Systems with battery storage will pay an additional 1-hour Inspection Fee of $160'; there is no battery/ESS line in the 2025 schedule, and the current hourly inspection rate is $207. 90% · citywide fee schedule effective 10-01-2025
• How is the fee calculated? Tiered - a flat amount within a size band, not valuation and not per-kW. Residential roof-mounted is a single $256 charge for anything under 25 kW; commercial is per 100 kW; utility scale is banded by MW. Lancaster's Building & Safety fee schedule for new construction is square-footage based, but solar is not billed that way. Gov. Code 65850.55 forbids valuation-based solar fees and Lancaster does not use one. 90% · citywide fee schedule effective 10-01-2025
• Is there a separate plan-check fee? No separate plan-check fee for residential solar - the $256 line is expressly 'PLAN CHECK/INSPECTION' combined. Separate charges exist only for extra work: PLAN RE-CHECK $249, SUPPLEMENTAL PLAN CHECK $249 per field, Stand Alone Electrical Plan Check $249, RE-INSPECTION $207 per hour, SUPPLEMENTAL INSPECTION $207, EMERGENCY/AFTER HOURS INSPECTION $413. 90% · citywide fee schedule effective 10-01-2025

Interconnection is a separate process from the permit and usually the longer pole. Where the utility does not depend on the permit being issued, running both at once is the single biggest saving available on a residential job.

• What is the stated plan-review turnaround? Depends which route. (a) Symbium instant permit: real time - 'your permit will be issued automatically, without manual review or an in-person visit'; this is the route the city has required for roof-mounted residential solar since November 1, 2024. (b) Conventional solar submittal: SPV Toolkit says 'Permits not approved over the counter will normally be reviewed in one business day.' (c) General building plan check: the plan check page says 'the first plan check is usually complete within three weeks', and the FAQ says 'First submittal plan review usually takes 2-3 weeks. Each subsequent plan review is 1-2 weeks.' California sets no statutory review deadline. 80% · permits page (Symbium notice) + SPV Toolkit + plan check page + FAQ
• How long is an issued permit valid before it expires? 360 days to start, then a rolling 180-day abandonment test. LMC 15.04.060 (as rewritten by Ord. 1139) amends CBC 105.5: a permit expires '(i) If work authorized by such permit is not commenced within 360 days from the issuance date of the permit', and (ii) once commenced, expires if 'suspended or abandoned', defined as the permittee having 'for a period of 180 days or longer after commencing the work ... failed to make substantial progress', with failure to schedule, undergo or pass a required inspection for 180 days deemed such a failure. The Building Official may grant written extensions of not more than 180 days each. A permit issued to legalise unpermitted work expires in 60 days (105.5.2). NOTE: the department FAQ states the abandonment period as 360 days and says an inspection extends a permit by 180 days - the ordinance is the controlling text and says 180. 90% · adopting ordinance LMC 15.04.060 (Ord. 1139)
• Which utility handles interconnection here? Southern California Edison. SCE is the wire and meter utility for Lancaster and is the party that processes interconnection under CPUC Electric Rule 21. Lancaster Energy (the city-run CCA, formerly Lancaster Choice Energy) is NOT the interconnecting utility - it supplies generation only: 'Southern California Edison continues to deliver the electricity, provides billing, customer service and power line maintenance and repair. Lancaster Energy only replaces the electric generation services.' LE runs its own NEM successor product, 'Personal Choice', but tells customers 'If you are new to net energy metering, please contact SCE at (800) 974-2356 to submit your interconnection application. Once you are enrolled with SCE's program, you will automatically be enrolled in Personal Choice.' 93% · CCA (Lancaster Energy) FAQ + SCE Rule 21
• Where does the utility sit in the sequence? Parallel, with the utility gating only the final energisation. LMC 15.45.040.D is explicit: the building official's administrative approval 'does not authorize an applicant to connect the small residential rooftop energy system to the local utility provider's electricity grid. The applicant is responsible for obtaining such approval or permission from the local utility provider.' On the SCE side, Rule 21 makes Permission to Operate contingent on the city's sign-off: for NBT/NEM facilities 1 MW or smaller, PTO 'shall normally be processed not later than thirty (30) Business Days following Distribution Provider's receipt of 1) a completed NBT/Net Energy Metering Interconnection Request ... 2) a completed signed ... Generator Interconnection Agreement; and 3) evidence of Applicant's final electric inspection clearance from the Governmental Authority having jurisdiction'. So the interconnection application can run alongside the permit, but PTO comes after the city final. 90% · adopting ordinance LMC 15.45.040.D + SCE Rule 21 Section F

The NEC edition a jurisdiction enforces is often a cycle behind the newest one published, and local amendments sit on top of it. Rapid shutdown, conductor sizing and labelling all change between editions, so the edition in force is the first thing to establish, not the last.

• Which NEC edition is in force? 2023 NEC, as the 2025 California Electrical Code, adopted locally by Ordinance No. 1139 as LMC Chapter 15.12, effective January 1, 2026. The Building & Safety page carries the notice: 'Effective January 1, 2026, the City of Lancaster will adopt the 2025 California Building Code. All new plan submittals must be designed per the 2025 Codes.' The current Design & Submittal Requirements sheet lists 'Electrical Code: 2025 California Electrical Code'. WARNING: the plan check page is stale and still says 'Lancaster enforces the requirements of the 2022 California Building, Electrical, Mechanical, Plumbing and Energy codes and the applicable amendments of the City of Lancaster set forth in Ordinance No. 1094' - Ord. 1094 was expressly repealed by Ord. 1139. 95% · adopting ordinance (Ord.

• Which fire code edition is in force? Both, with the more restrictive governing - and this is the distinctive Lancaster fact. LMC 15.32.010.A adopts 'the 2025 California Fire Code, while maintaining the 2026 Los Angeles County Fire Code, including appendix B, appendix C, of the 2025 California Fire Code ... as the Lancaster Fire Code'. 15.32.010.B: 'If a conflict should exist between the 2025 California Fire Code and the 2026 Los Angeles County Fire Code, then the more restrictive will govern.' The Design & Submittal Requirements sheet simply lists 'Fire Code: 2026 County of Los Angeles Fire Code'.

• Are there local amendments to any of the above? Yes - and one of them bites directly on PV. LMC 15.12.040 'Solar photovoltaic systems' amends Article 690 of the 2025 CEC by adding 690.15.1 (see q48). LMC 15.12.050 expressly permits off-grid stand-alone PV/fuel-cell/battery/wind systems subject to 'all off-grid development standards approved by the Building Official'. LMC 15.12.060 restricts who may pull an electrical permit. LMC 15.04.060 rewrites permit expiration. Chapter 15.32 amends the fire code and pins it to the LA County Fire Code. Chapter 15.25 adds a post-disaster placard system (unrelated to PV signage).

The city's inspection guide phrases the field standard as conformance to the approved plan on every item - module count and model, mounting and structural connections, roof penetration flashing, conduit, firefighter access, fire classification, grounding/bonding, listings, conductor and OCPD types and sizes, disconnect locations, markings and labels, and CEC 110.26 working space. 90% · adopting ordinance + SPV Toolkit Doc #6 Inspection Guide

Ridge setbacks and roof access pathways are fire-service requirements and they constrain the array layout. They are the most common cause of a redesign after the fire department comments on a plan set.

• What ridge setback and access pathways are required? Lancaster adopts no ridge-setback or pathway amendment of its own; the enforceable requirement is CRC R329 / CFC 1205 in the 2025 codes, taken together with the 2026 LA County Fire Code (more restrictive governs, LMC 15.32.010.B). The city's published guidance is badly out of date on this point in two places: the SPV Toolkit points applicants to the 'State Fire Marshal Solar PV Installation Guide', and the copy Lancaster actually hosts is the April 22, 2008 OSFM guideline, which is advisory ('should') and uses the old scheme - modules no higher than three feet below the ridge, one 3-foot clear access pathway from eave to ridge on each roof slope for hip-roof buildings, two such pathways for a single-ridge residence, centreline axis pathways in both axes; the toolkit's own inspection guide cites CFC 605.11.3.1-605.11.3.3.3 and CRC R331.4, both dead section numbers.

Which rapid-shutdown rule applies follows directly from the NEC edition in force, and the initiation device has to be at a location the fire service can reach and identify. This is inspected, and it is labelled.

• Is rapid shutdown required, and to which NEC edition? Yes - to the 2023 NEC / 2025 CEC 690.12 as adopted in LMC 15.12.010, with no local amendment. Lancaster adds a fire-side layer through the LA County Fire Code: LACoFD requires that where a PV system has a required Rapid Shutdown, Hazard Control System or similar feature, 'an initiation device for each such function shall be included among the placarded disconnects', that these be accessible from the exterior, and that they be counted in the 'X of Y' placard total 'for each PV system having one, new or existing'. 85% · adopting ordinance + LACoFD Guide Appendix B

The NEC sets a baseline for permanent markings at the service equipment and the disconnecting means. On top of that, an authority may specify its own wording, and the utility may specify more again. Where any of them writes its own text, a generic off-the-shelf label set will not pass — this is the detail most often fixed on a return visit.

• Which placards does this authority require at the service equipment? Two stacked sets. (A) The NEC/CEC labels, laid out on the Markings page of the city's own Standard Plan under the heading 'CEC Articles 690 and 705 and CRC Section R331 require the following labels or markings be installed at these components of the photovoltaic system': WARNING / INVERTER OUTPUT CONNECTION; DO NOT RELOCATE THIS OVERCURRENT DEVICE (CEC 705.12(D)(7), 'not required if panelboard is rated not less than sum of ampere ratings of all overcurrent devices supplying it'); WARNING / DUAL POWER SOURCES / SECOND SOURCE IS PHOTOVOLTAIC SYSTEM / RATED AC OUTPUT CURRENT - ___AMPS AC / NORMAL OPERATING VOLTAGE ___VOLTS; PV SYSTEM AC DISCONNECT / RATED AC OUTPUT CURRENT - ___AMPS / AC NORMAL OPERATING VOLTAGE ___VOLTS; PV SYSTEM DC DISCONNECT / RATED MAX POWER-POINT CURRENT- ___ADC / RATED MAX POWER-POINT VOLTAGE- ___VDC / SHORT CIRCUIT CURRENT- ___ADC / MAXIMUM SYSTEM VOLTAGE- ___VDC; WARNING / ELECTRIC SHOCK HAZARD. THE DC CONDUCTORS OF THIS PHOTOVOLTAIC SYSTEM ARE UNGROUNDED AND MAY BE ENERGIZED (ungrounded systems only); WARNING / ELECTRIC SHOCK HAZARD / IF A GROUND FAULT IS INDICATED, NORMALLY GROUNDED CONDUCTORS MAY BE UNGROUNDED AND ENERGIZED; WARNING / ELECTRIC SHOCK HAZARD / DO NOT TOUCH TERMINALS / TERMINALS ON BOTH LINE AND LOAD SIDES MAY BE ENERGIZED IN THE OPEN POSITION; WARNING: PHOTOVOLTAIC POWER SOURCE 'marked on junction/combiner boxes and conduit every 10 ft'; and a permanent plaque or directory denoting all electric power sources on or in the premises (CEC 705.12). (B) The LA County Fire Department Electrical Power Source Disconnect Placarding System, which reaches Lancaster because LMC 15.32.010 adopts the 2026 LA County Fire Code and Lancaster contracts with LACoFD for fire service: an exterior placard reading 'F.D. - ELECTRICAL BLDG DISCONNECT # X of Y' and panel-interior placards reading '#X'. 85% · SPV Toolkit Doc #3 Markings page + LACoFD Guide Appendix B
• Does the authority specify placard wording of its own? Yes - not by the City of Lancaster's own drafting, but through the LA County Fire Code it adopts. LACoFD specifies placard verbiage that exists nowhere in the NEC: exterior placards read 'F.D. - ELECTRICAL BLDG DISCONNECT # X of Y'; panel-interior placards read '#X'. 'Verbiage and word arrangement shall be as pictured above, wherein "X" and "Y" are replaced with the appropriate numbers based upon the determination of a C-10 electrician (or other classification when a C-10 is not required for the scope of work being performed), with approval of the fire code official. All "X"s shall account for the total number "Y" of essential switches and/or panels to be operated in order to completely disconnect the structure from all power sources (and activate rapid shutdown, when applicable).' The system must account for every source capable of supplying the structure - utility, generator, PV, ESS, wind, fuel-cell, vehicle-to-grid - and 'A pre-wired optional auxiliary power source input shall also constitute a wired capability to be served by more than one power source, and therefore shall require a placarded disconnect'. The City of Lancaster itself publishes no placard wording of its own beyond reprinting the state Standard Plan's NEC labels; LMC Chapter 15.25 'Use of placards' is a post-earthquake safety-evaluation posting system and has nothing to do with PV. 85% · LACoFD Guide for ESS, PV and Disconnects, Appendix B (Rev. 3, 2023-09-01)

SIZE AND MATERIAL: 'Exterior Placards (FIGURE 1) shall be a minimum 2 inches tall by 3.5 inches wide weather resistant plastic, with verbiage engraved'; 'Panel-Interior Placards (FIGURE 2) shall be a minimum 7/16 inches tall by 3/4 inches wide weather resistant plastic, with verbiage engraved'. COLOUR: 'Color shall be red letters engraved into a yellow "background" with the verbiage as displayed.' CHARACTER TYPE: exterior - 'Solid, all-capitals, in Arial font, minimum font size 24. "F.D." and "# X of Y" shall be in bold type and minimum font size 28'; panel-interior - 'Solid, all-capitals, in Arial font, bold, minimum font size 24.' ATTACHMENT: 'Attachment shall be by means of permanent epoxy that is material, weather, and surface compatible.' For the NEC-derived labels, Lancaster's own Standard Plan gives only an advisory note, not a mandate: 'ANSI Z535.4 provides guidelines for the design of safety signs and labels for application to products. A phenolic plaque with contrasting colors between the text and background would meet the intent of the code for permanency. No type size is specified, but 20 point (3/8") should be considered the minimum.' 85% · LACoFD Guide Appendix B sections B.1-B.4 + SPV Toolkit Doc #3 informational note
• Is a site plan / facility map placard required, and what must it show? A directory placard yes; a firefighter site-map placard no. The city's Standard Plan states plainly: 'CEC 705.12 requires a permanent plaque or directory denoting all electric power sources on or in the premises.' Separately, a roof-layout DIAGRAM is a plan-submittal requirement, not a placard: the Eligibility Checklist requires 'A diagram of the roof layout of all panels, modules, clear access pathways and approximate locations of electrical disconnecting means and roof access points', and the Roof Layout Diagram sheet repeats 'Items required: roof layout of all panels, modules, clear access pathways and approximate locations of electrical disconnecting means and roof access points'. The function a site-map placard would serve is instead met by LACoFD's 'X of Y' numbering, which tells a firefighter at any placarded disconnect how many exist in total and that they have found one of them. 80% · SPV Toolkit Doc #3 Markings page + Doc #2 Eligibility Checklist + LACoFD Guide
• Does the UTILITY specify placards beyond the AHJ's? Yes, one - and it is conditional, not a standing placard. SCE Rule 21 H.1.d requires the visible disconnect to 'be clearly marked on the submitted single line diagram and its type and location approved by Distribution Provider prior to installation. If the device is not adjacent to the PCC, permanent signage must be installed at a Distribution Provider approved location providing a clear description of the location of the device. If the switch is not accessible outside the locked premises, signage with contact information and a Distribution Provider approved locking device for the premises shall be installed.' The switch itself must 'include markings or signage that clearly indicates open and closed positions.' Rule 21 specifies no letter height, colour or material for any of this. Generating Facilities with non-islanding inverters totalling 1 kVA or less are exempt from the visible-disconnect requirement altogether. Lancaster Energy, the CCA, imposes no placards - it does not touch the wires. 85% · utility tariff - SCE Electric Rule 21, Generating Facility Interconnections
• Where must the labels be placed? LACoFD placards: 'Each placarded disconnect initiation device shall be accessible from the exterior of the structure(s).' 'Exterior Placards shall be placed onto the exterior of, or immediately adjacent to, each panel/enclosure or standalone disconnect switch that is necessary to be operated. Additional Exterior Placards may be required by the fire code official, such as when an enclosure houses multiple panels, or when more than the "Main" within a placarded panel is necessary to be operated.' 'Panel-Interior Placards are required to be placed inside a panel to identify specific switches/breakers when multiple switches within a single panel/enclosure are required to be operated.' Placement locations 'shall be determined by a C-10 electrician ... and are subject to approval by the fire code official', and where the need for additional placards is unclear the fire code official decides. NEC-derived labels go at their code-specified components, as drawn on the city's Standard Plan Markings page: at the PV system DC disconnect, at the PV system AC disconnect, at the inverter output connection / point of connection overcurrent device, at the load centre or service panelboard for the DUAL POWER SOURCES marking, on junction and combiner boxes, on conduit every 10 feet, and the CEC 705.12 directory at the service equipment. 87% · LACoFD Guide Appendix B + SPV Toolkit Doc #3 Markings page

Where the AC disconnect must sit relative to the meter is usually the utility's rule, not the building department's. Battery storage frequently carries its own permit, its own inspection and its own fire conditions.

• Where must the AC disconnect be, relative to the meter? Lancaster has a real local amendment here, and it is a proximity rule, not a distance. LMC 15.12.040: 'Article 690 of the 2025 California Electrical Code is hereby amended by adding the following: 690.15.1 Disconnecting Means. A lockable type disconnecting means rated for the output amperage shall be installed immediately adjacent to the service equipment on the output side of the inverter. Exception: If the inverter with an integrated disconnect is located adjacent to the service equipment (line of sight), the disconnecting means as stated above shall not be required.' The fire code adds an actual measured distance: 2023/2026 LACFC 509.3 - 'Required disconnection and/or attenuation means for electrical hazards shall be located within 6 feet (1829 mm) of the main service panel, on the same wall plane, and maintained not separated from one another by walls, gates, fences, vegetation, or architectural features of the building', with a case-by-case exception by the fire code official requiring clear permanent signage. SCE Rule 21 sets NO distance at all - only that the isolating switch be 'near the Point of Interconnection', allow visible verification of separation, be markable open/closed, be reachable 24 hours a day by SCE without keys or special permission, and be capable of being locked in the open position; systems with non-islanding inverters of 1 kVA or less are exempt. The widely repeated 'within 10 feet of the meter' rule appears in none of these three documents. 90% · adopting ordinance LMC 15.12.040 + LACFC 509.3 + SCE Rule 21 H.1.d
• Must equipment be on a specific approved list? Yes, in the listing sense rather than a city-maintained brand list. Lancaster's Standard Plan requires that 'Listed and labeled equipment shall be installed and used in accordance with any instructions included in the listing or labeling (CEC 110.3)' and that 'Equipment intended for use with PV system shall be identified and listed for the application (CEC 690.4[D])', with the inspection guide checking DC modules listed to UL 1703, AC modules to UL 1703 and UL 1741, and the inverter marked 'utility interactive'. For batteries, LACoFD requires UL 9540 listing for the ESS and UL 1741 for its inverter, and adds that 'ESS listed and labeled solely for utility or commercial use shall not be used for residential applications'. On the utility side SCE maintains an approved inverter/PCS list for Rule 21 certified equipment. Lancaster itself publishes no approved-products list. 85% · SPV Toolkit Docs #3/#6 + LACoFD checklist + SCE Rule 21 equipment lists
• Are batteries permitted, and under what conditions? Yes, and the binding conditions come from the LA County Fire Code, not from Lancaster. LMC 15.12.050 permits stand-alone and off-grid battery systems generally. The city routes residential battery storage through Symbium instant permitting alongside solar. The numeric limits are LACoFD's: individual ESS units rated at a maximum of 20 kWh; aggregate 80 kWh per site, and 80 kWh maximum per location for each of inside attached garages, inside detached garages, outdoors on the outer side of exterior building walls, and outdoors on the ground; individual units separated 3 feet from one another; a minimum 3 feet in any direction from doors, windows, operable openings, HVAC inlets and other penetrations into habitable or occupiable spaces or bathrooms; 5 feet from lot lines, public ways, other buildings, stored combustibles and hazardous materials; 10 feet from vegetation; impact protection where subject to vehicle damage (exception where no portion is less than 36 inches above the finished floor), by 48" x 3" schedule 80 pipe bollard in a 12"-deep 6"-diameter concrete pier, or a 36" retrofit bollard on an 8" square 1/4" plate with four 1/2" x 4" anchor bolts, spaced not more than 4 feet on centre and no closer than 6 inches to a unit; and, in an attached garage, a heat alarm, a heat detector tied to the residence fire alarm, or a sprinkler with flow detector, notifying inside the dwelling and in the garage. 85% · LACoFD Expedited PV/ESS Inspection Checklist + Guide (2023-09-01)
• Is there a separate ESS permit or inspection? A separate FIRE inspection, yes; a separate city permit, not clearly. Lancaster issues battery storage through the same Symbium instant route as solar and its 2025 fee schedule carries no ESS line (the 2017 toolkit added a $160 one-hour inspection fee for systems with battery storage). But LACoFD does not delegate ESS: its guide states the delegation of residential solar-on-roof review to building and safety 'does not extend to ... Energy Storage Systems (ESS or BESS)', ESS installations of more than 3 kWh require LACoFD inspection, and 'The applicant for this construction permit shall contact the County of Los Angeles Fire Department (LACoFD) Fire Prevention Division and schedule and pass an inspection prior to use of the PV or ESS installation(s)'. That LACoFD inspection is separately invoiced and 'Invoices unpaid at the time of the inspection will result in a cancellation of inspection.' 82% · LACoFD expedited PV/ESS page and guide + city Instant Permits page + fee schedule
• Is a ground mount treated as a structure? Yes. LMC 17.08.300.B requires a building permit for any solar energy system, and 17.08.300.C subjects ground-mounted systems to zoning controls that only apply to structures: 'All ground-mounted solar energy systems shall not be located within the required front, side, or rear building setbacks, or front yard area, and shall comply with all applicable height restrictions', and 'To the extent possible, without compromising the solar energy system's access to the sun, ground-mounted solar energy systems shall be screened from view at-grade from all adjacent streets and adjacent properties.' Structurally, the city gives ground mounts their own design criterion: 'Ground Snow Load to be used only for ground mounted solar panels = 5 lbs./sq. ft.' The expedited/Standard Plan route is roof-mounted only, so a ground mount goes through conventional plan check. 90% · zoning ordinance LMC 17.08.300 + Design & Submittal Requirements 01-26
• Is there a local rule on service upgrades or busbar sizing? No local busbar or service-upgrade amendment. What exists is (a) an eligibility limit rather than a rule - the Standard Plan and Eligibility Checklist require 'a single-phase AC service panel of nominal 120/220 Vac with a bus bar rating of 225 A or less' and connection to the load side of the utility distribution equipment, and the plan's point-of-connection worksheet applies the CEC 705.12 120% rule ('Sum of the main OCPD and the inverter OCPD is rated for not more than 120% of the bus bar rating'), and (b) LMC 15.12.030, which lists conditions under which service or sub-panels must be repaired or removed, including visual evidence of overload, working space not maintained per CEC Table 110.26(A)(1), live-front panels, and fuses or breakers rated higher than the Electrical Code permits. 82% · SPV Toolkit Docs #2/#3 + adopting ordinance LMC 15.12.030
• Is a specific mounting system or attachment spacing required? No proprietary system is mandated, but Lancaster publishes prescriptive attachment limits for the no-engineer route. Structural Criteria (Toolkit Doc #5): modules parallel to the roof plane with a 2" to 10" gap between the underside of the module and the roof surface; no overhang of ridges, hips, gable ends or eaves; modules plus support components no more than 4 psf for PV (5 psf for solar thermal); array covering no more than half the total roof area across all roof planes; proposed anchor horizontal spacing less than the Table 1 value for the measured roof slope and rafter spacing (16", 24" or 32" o.c.); and anchor fasteners of 5/16" diameter lag screws with 2.5" embedment into the rafter, or meeting the racking manufacturer's guidelines. Manufacturer's project-specific racking worksheets or calculator output must be attached. Additionally, Design & Submittal Requirements sets 'Ground Snow Load to be used only for ground mounted solar panels = 5 lbs./sq. ft.' 90% · SPV Toolkit Doc #5 + Design & Submittal Requirements 01-26

Booking is a portal, a phone call or an email depending on the authority, and the notice required is rarely zero. Book before the work is finished rather than after — the lead time, not the work, is usually what sets the date.

• How is an inspection booked? Portal. Inspections are booked on the Accela Citizen Access portal at https://aca.accela.com/lancaster - 'You may schedule an inspection on our Online Permit Portal'. The portal also shows the scheduled time range and assigned inspector. The city publishes an ACA How-To Guide: Schedule Inspections. Phone is not the booking channel: 'Inspectors will NOT answer their phones during inspection hours' - but each inspector has a published text-only mobile number for day-of coordination. Note the LACoFD ESS/PV inspection is booked separately, by phoning the jurisdictional LACoFD regional inspection office and emailing the request. 92% · department inspections page
• How much notice is required? One business day, with a hard cut-off: 'be aware the deadline to schedule an inspection will be 2:00 pm the day before the requested date'. The SPV Toolkit adds that solar 'Inspection requests are typically scheduled for the next business day. If next business day is not available, inspection should happen within a five-day window.' 90% · department inspections page + SPV Toolkit Doc #1
• Are same-day or AM/PM windows offered? Two-hour windows, replacing AM/PM. Inspections page notice: 'Beginning December 1, 2025, our inspection schedule will transition to a two-hour time window system instead of the current AM/PM format. Each morning at 7:30 a.m., the permit contact will receive an email confirming their assigned two-hour inspection window for that day. The first inspection will begin at 8:00 a.m., so contractors/applicants should plan to be ready at that time even if they have not yet received their email. You will still have the ability to text your inspector to maintain open communication and coordinate as needed.' Same-day is not offered (2:00 pm previous-day cut-off). Overtime inspections 'are available and are based upon inspector availability. These inspections must be prepaid and coordinated with your inspector' - EMERGENCY/AFTER HOURS INSPECTION $413. 92% · department inspections page + citywide fee schedule

Some authorities inspect their own solar work; some delegate it, and a few do not inspect the PV equipment itself at all. Who is coming determines what they will look at.

• Does this AHJ perform its own final solar inspection? Yes for the electrical/building final - City of Lancaster Building & Safety inspectors do it, and the department publishes the five inspectors by name with desk and text numbers. But it is not the whole story: for a project with energy storage, or any PV project where LACoFD review is triggered, the LA County Fire Department performs its own separate inspection, invoiced separately, and 'A Passed Inspection Serves as an Operational Permit at a R-3/R-4 Occupancy, on the condition that it passes other necessary requirements from other agencies having jurisdiction (e.g., B&S, Utility, etc.).' 88% · department inspections page + LACoFD checklist
• If delegated, to whom? Fire only, and it runs in the opposite direction from what you would expect. LACoFD DELEGATES to the city: 'The Los Angeles County Fire Department (LACoFD) has historically delegated fire-official authority, for plan review and inspection of conventional residential solar-on-roof installations at one- or two-family dwellings (i.e., at R-3/R-4 Occupancies), to the jurisdictional building and safety department' - but that delegation 'does not extend to' energy storage systems or to a subcategory of building-integrated PV, and LACoFD retains electrical-disconnect placarding and rapid-shutdown activation devices for its own inspection. Nothing is delegated to a third-party inspection agency. Where LACoFD review is needed, the applicant contacts the LACoFD Fire Prevention regional or specialty-unit office directly; Lancaster's local Fire Prevention Office is at 335-A East Avenue K-6 (661) 949-6319. 88% · LACoFD Guide sections I-II + city fire department page

A rough-in or mid-roof inspection, where one is required, has to happen before the work it covers is closed up. Missing a stage means opening something back up, and it is the most expensive kind of correction.

• Which inspections are required, and in what order? For an eligible small residential rooftop system: one inspection. LMC 15.45.040.B: 'For a small residential rooftop solar energy system eligible for expedited review, only one (1) inspection shall be required, which shall be done in a timely manner. If a small residential rooftop solar energy system fails inspection, a subsequent inspection is authorized; however, the subsequent inspection need not conform to the requirements of this subsection.' The city's general inspection-type list includes an Electrical category (Temporary Power Pole, Under Slab Electrical, Ufer Ground, Rough Electrical Wiring, Final Electrical/Safe Electric) that a non-qualifying or larger project would be sequenced through. If an ESS is involved, add a separate LACoFD inspection which must be passed 'prior to use of the PV or ESS installation(s)'. 90% · adopting ordinance LMC 15.45.040.B + inspections page
• Is a rough-in or mid-roof inspection required? No. There is no rough-in or mid-roof inspection for an eligible small residential rooftop PV system - the ordinance allows exactly one inspection. Lancaster does run a Pre-roof inspection ('A visual inspection by the inspector must be performed prior to commencement of new roof installation') and a Roof Sheathing inspection, but those belong to reroof and new-construction work, not to a PV retrofit on an existing roof. 85% · adopting ordinance LMC 15.45.040.B + inspections page

The approved plan set, the permit, and the equipment listings should be on site and reachable. Inspectors routinely verify that installed equipment matches what was approved, and that the labels are the ones the plan set promised.

• Is there a published inspection checklist? Yes - two, from two authorities. The City publishes SPV Toolkit Document #6, 'Inspection Guide for PV Systems in One- and Two-Family Dwellings', in two parts: a single-page Field Inspection Guide of 19 items and a Comprehensive Inspection Reference. Caveat: it states 'All California Electrical Code (CEC), California Residential Code (CRC), California Building Code (CBC) and California Fire Code (CFC) references are to the 2016 versions unless otherwise noted' - two full code cycles out of date. LACoFD publishes its own 5-page 'Expedited PV/ESS Permitting Process - LACoFD Inspection Checklist for Group R-3/-4 ESS, PV, and Electrical-Disconnect Placarding', effective 2023-09-01. 90% · SPV Toolkit Doc #6 + LACoFD inspection checklist
• What must be on site at inspection? Approved plans, the permit, the inspection record card, and a ladder. 'Approved building plans must remain at the site and made available to the inspector along with the permit card.' 'An Inspection Record Card must be posted or made available to allow the inspector to make the required entries relative to inspection of the work. This card shall remain posted or made available until final approval has been granted.' 'Photographs and videos are not accepted for inspection purposes.' The SPV Toolkit adds 'An approved ladder must be present at the site for the inspector's use', and the city publishes a separate Ladder Requirements handout: customer provides the ladder; manufacturer's labels visible and legible; extension ladders minimum Type I heavy-duty industrial rated 250 lb; telescoping, folding or A-frame ladders unacceptable; able to extend 36 inches above the eave or fascia; set at a 4:1 slope (75 degrees); firmly secured at the eave; slip-resistant bases; nonconductive ladders required around any electrical work or electrical lines. Fall-protection anchorages must be in place before inspection, designed for 5,000 lb per person, omitted only for roof slopes less than 2:12; roof clean and free of debris; all rooftop construction complete with no workers on the roof. For construction waste, receipts showing 65% diversion are required as a condition of permit final. A reinspection fee may be assessed if the record card is not posted or the plans are not available. For the LACoFD inspection: digital proof of the construction permit, disconnect placarding already in place, and LACoFD fees paid. 92% · Ladder Requirements handout (DPW0546) + inspections page + SPV Toolkit + LACoFD checklist
• Does the inspector verify labels and listings? Yes. The city's own inspection guide checks both. Labels: 'Appropriate signs are property constructed, installed and displayed, including the following - Sign identifying PV power source system attributes at DC disconnect; Sign identifying AC point of connection; Sign identifying switch for alternative power system', and 'PV system markings, labels and signs according to the approved plan.' Listings: 'Equipment installed, listed and labeled according to the approved plan (e.g., PV modules, DC/DC converters, combiners, inverters, disconnects, load centers and electrical service equipment)', 'For grid-connected systems, inverter is marked "utility interactive"', 'DC PV modules are listed to UL 1703. AC modules are listed to UL 1703 and UL 1741'. Equipment ratings are checked against the installed signs (inverter rating at least the max voltage on the PV power source sign; DC OCPDs DC-rated at least as high; AC OCPD at least 125% of maximum current on the sign; sum of main and inverter OCPDs not more than 120% of bus bar rating). LACoFD separately inspects placard size, material, colour, character type, verbiage, attachment means and placement. 90% · SPV Toolkit Doc #6 Inspection Guide + LACoFD checklist section IV

Passing gives you a final or an equivalent sign-off. That is not the same as permission to operate: PTO comes from the utility, and who tells the utility the inspection passed varies. A system left switched off for weeks is usually waiting on this handover.

• What is issued on pass? Final. For a PV retrofit the deliverable is a passed final inspection signed off on the inspection record card in Accela - no certificate of occupancy is involved, since there is no new occupancy. Lancaster's general Final inspection for buildings does require Certificate of Occupancy forms and CF3R forms to be signed and given to the inspector, and the city publishes an Application for Certificate of Completion and an Application for Certificate of Occupancy for the cases that need them. LMC 15.04 amends CBC 111.1 to bar use or occupancy without it for buildings. Where an ESS is involved, LACoFD's passed inspection additionally 'Serves as an Operational Permit at a R-3/R-4 Occupancy'. 78% · inspections page + fee schedules and forms page + LACoFD checklist
• Who notifies the utility for PTO? Installer/applicant. The city does not notify SCE. LMC 15.45.040.D: administrative approval 'does not authorize an applicant to connect the small residential rooftop energy system to the local utility provider's electricity grid. The applicant is responsible for obtaining such approval or permission from the local utility provider.' SCE Rule 21 then requires the applicant to supply the city's sign-off: Permission to Operate for a NEM/NBT facility of 1 MW or smaller 'shall normally be processed not later than thirty (30) Business Days following Distribution Provider's receipt of 1) a completed NBT/Net Energy Metering Interconnection Request including all supporting documents and required payments; 2) a completed signed NBT/Net Energy Metering Generator Interconnection Agreement; and 3) evidence of Applicant's final electric inspection clearance from the Governmental Authority having jurisdiction over the Generating Facility.' Enrolment in the CCA's net-metering product, Lancaster Energy 'Personal Choice', then follows automatically once SCE's NEM enrolment is complete. 92% · SCE Rule 21 Section F + adopting ordinance LMC 15.45.040.D
• Is there a re-inspection fee? $207 per hour. Citywide Fee Schedule effective 10-01-2025: 'RE-INSPECTION $207 per hour'; SUPPLEMENTAL INSPECTION $207; PLAN RE-CHECK $249; EMERGENCY/AFTER HOURS INSPECTION $413. It is not automatic on a first failure: the Ladder Requirements handout says 'In the event of a failed inspection, the Contractor may schedule one subsequent re-inspection at no additional cost. In the event that the installation fails twice for any of the items listed above, a re-inspection fee equal to the cost of one hour inspection time may be required.' The Inspections page lists the triggers: work not complete, corrections not made, inspection record card not posted or available, plans not made available, access not provided, or deviating from plans without the Chief Building Official's approval. 90% · citywide fee schedule + Ladder Requirements handout + inspections page
• How are corrections issued and cleared? Plan review: a written correction list, then resubmit. 'Upon completion of your initial review, you will be provided a correction list of the items that do not meet code requirements. Once you make the necessary changes, you will need to return the plans for a second review.' For solar specifically, LMC 15.45.040.C requires that 'Upon receipt of an incomplete application, the building official shall issue a written correction notice detailing all deficiencies in the application and any additional information required to be eligible for expedited permit issuance.' Corrections are tracked in Accela; PLAN RE-CHECK is $249. Field: the inspector records results on the inspection record card, the applicant fixes and rebooks through ACA by 2:00 pm the day before; one free reinspection, then $207 per hour. 88% · plan check page + adopting ordinance LMC 15.45.040.C + inspections page
