City of Lodi

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 95% · department procedure
• What does this authority permit itself, and what does it delegate? Both — City Building Division issues a single combined building/electrical PV permit; Lodi Electric Utility (a separate City department, the municipal electric utility) holds a parallel interconnection pre-approval gate that must clear before the Building Division will accept the permit application. 90% · department procedure
• Is a permit required for a residential rooftop PV system? Yes 95% · department procedure
• Is there a separate electrical permit, or is it combined? Combined — a single 'Solar Permit' issued by the Building Division covers building and electrical scope. LEU separately charges its own 'Electrical Permit' fee ($89) as part of its interconnection package, but that is a utility charge, not a second city permit. 80% · fee schedule
• Is a HOA or architectural approval required first? No city-level HOA/architectural-approval step is required in Lodi's own permitting procedure, and any such restriction would in any case be void under the California Solar Rights Act. 75% · state statute
• Is a wind or windstorm certification required? No separate wind/windstorm certification process — wind speed (93 mph, 3-second gust, Exposure B for residential) is a structural design parameter applied during ordinary plan review, not a stand-alone certificate requirement (California is not a TDI-style wind-cert state). 65% · department page
• Is there a system-size cap on residential generation? No fixed city-wide kW cap. LEU's sizing rule ties the maximum allowable system size to the site's trailing 12-month energy usage (EPBB-based, cannot exceed prior usage). Separately, the Building Division's own 'Residential – Photovoltaic Checklist' caps at '10 KW AC CEC rating or less' for that specific streamlined checklist route, while the fee schedule prices systems up to 15kW at a flat rate before adding a per-kW charge, and LEU's general guidelines cover systems 'of 1 MW or less.' These are three different administrative thresholds, not one consistent cap. 70% · utility DG manual

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? Either 85% · department procedure
• Must the contractor be registered with this authority before applying? Yes, for the online/SolarAPP+ route 80% · department procedure
• Is a homeowner permitted to self-install and self-permit? Yes 90% · department procedure

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? Two complete sets of plans including LEU PowerClerk pre-approved drawings/panel layout (with DocuSign Envelope ID), manufacturer spec sheets/owner's manuals, a cover sheet citing the applicable code editions, a site plan, a roof plan showing panel layout and access pathways, an electrical one-line diagram with conductor/overcurrent calculations, and (if existing rafters are over-spanned) separate structural calculations stamped by a licensed architect or PE. 88% · published checklist
• How many copies, and in what format? Two complete sets, on 11" x 17" or larger (paper); electronic submittal accepted via the eTRAKiT/SolarAPP+ online route. 85% · published checklist
• Is a site plan required, and what must it show? Yes. The site plan must show the location of the Electric Service Meter, the lockable AC disconnect, inverters, and any other required electrical equipment (sub-panels, additional meter sockets, DC lockouts, etc.). 90% · published checklist
• Is a one-line / three-line diagram required? Yes for the one-line diagram (required on all residential PV submittals); a three-line diagram is called out only in LEU's commercial solar guidance, not the residential path. 85% · published checklist
• Are string and conductor calculations required? Yes 90% · published checklist
• Is a structural PE stamp required, and at what threshold? Conditional, not blanket: a structural PE/architect stamp is required only when existing roof framing is found to be over-spanned against the rafter-span table — the checklist cites '2022 CRC, Table R802.4.1' for that comparison even though the same document elsewhere states the 2025 CRC is in force, an internal edition inconsistency in the city's own document. 75% · published checklist

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? Three portals in sequence: Lodi Electric Utility's PowerClerk (mandatory interconnection pre-approval, https://lodipvpermits.powerclerk.com), the City's eTRAKiT permitting portal (https://lodi-trk.aspgov.com/etrakit), and SolarAPP+ (optional, licensed-contractor-only alternate path). 88% · department procedure
• Can the whole application be completed online? Yes, largely — LEU pre-approval, City permit application/payment, and (for the SolarAPP+ path) approval and permit issuance can all be completed online; only physical inspection and any structural-calc submittal for over-spanned rafters require paper/in-person elements. 75% · department procedure
• What does a residential solar permit cost? City: $375 flat for a system up to 15kW, plus $15 for each additional kW over 15kW, plus $1 BSASRF and $13 SMIP state surcharges. LEU adds an Interconnection Fee of $839 (FY2026-27, single-phase 60-200A service; higher for 3-phase), an $89 LEU Electrical Permit fee, and a $178 LEU Inspection Fee (base LEU total roughly $1,106+ depending on service size), plus $15 per additional sub-panel/inverter and $10-20 for service size. 85% · fee schedule
• How is the fee calculated? Tiered/Flat with a per-kW component on the city side (flat $375 up to 15kW, then $15/kW); LEU's own interconnection fee is flat-tiered by service size/phase (single-phase 60-200A vs three-phase bands), not per-kW. 85% · fee schedule
• Is there a separate plan-check fee? No separate plan-check fee found — the residential PV fee table shows a single flat/tiered city permit fee with no distinct plan-check line item. 70% · fee schedule

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? Two-stage turnaround: LEU pre-approval review 'can take up to two weeks'; then the City Building Division reviews the completed application 'within 72 business hours of receiving LEU approval.' 90% · department page
• Which utility handles interconnection here? Lodi Electric Utility (LEU) — a City of Lodi municipally-owned electric utility, not PG&E. Lodi is a publicly-owned-utility (POU) city and is not CPUC Rule 21-jurisdictional; interconnection is governed entirely by LEU's own rules. 95% · utility DG manual
• Where does the utility sit in the sequence? Before permit — LEU pre-approval is mandatory prior to the Building Division accepting a permit application. 95% · utility DG manual

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 incorporated/amended into the 2025 California Electrical Code (CEC), effective January 1, 2026. 90% · adopting regulation
• Which building code edition is in force? 2025 California Building Code (Vols. 1 & 2) and 2025 California Residential Code, effective January 1, 2026. 92% · adopting regulation
• Which fire code edition is in force? 2025 California Fire Code (CFC), effective January 1, 2026. 85% · adopting regulation
• Are there local amendments to any of the above? Yes — local structural design criteria (93 mph 3-second-gust wind speed, Exposure B for residential/C for commercial, Seismic Design Category D/D1, 1,500 psf default soil bearing) and adoption of NEC Annex C for conduit-fill purposes, per City of Lodi Code of Ordinances §§15.02-15.20 as cited on the design-criteria sheet. 85% · adopting regulation
• What is the installation judged against? The 2025 CRC/CBC/CEC/CFC/Energy Code as locally amended (see Q32), plus the City's Residential Photovoltaic Checklist and LEU's Engineering Standard 942-0240 and Solar Installation Guidelines for the utility-side interconnection requirements. 85% · ordinance/checklist

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? Panels no higher than 3' from the ridge (for fire-department ventilation); minimum 3'-wide pathway from ridge to array; minimum 3'-wide pathway from eaves to ridge on both sides of the array; panels set back at least 1.5' from a hip or valley if arrays sit on both sides of it (may sit adjacent if only one side is paneled); these pathway/setback rules do not apply to patio covers, carports, or trellises. 92% · fire code + amendments

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, rapid shutdown is required to 2025 CEC (NEC 2023) Articles 690.12 and 690.56(C); required signage reads 'PV EQUIPMENT PROVIDED WITH RAPID SHUTDOWN.' 90% · published checklist

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? At minimum: a 'CAUTION: DUAL POWER SUPPLY' placard at the electric service panel; permanent labels on all PV disconnects; 'CAUTION SOLAR CIRCUIT' marking on DC conduit/raceways; a rapid-shutdown placard; and, per LEU's own Engineering Standard 942-0240, dedicated 'PHOTOVOLTAIC BREAKER,' 'PHOTOVOLTAIC DC DISCONNECT,' and 'PHOTOVOLTAIC INVERTER' labels at the generation-metering equipment. 90% · ordinance / utility spec
• Does the authority specify placard wording of its own? Yes 90% · published checklist
• Does it specify letter height, colour or material? Two distinct specs exist and do not fully agree: the Building/Fire checklist requires white lettering, minimum 3/8" high, all capitals, Arial or similar font, on a red background, reflective and weather-resistant material. LEU's own (older) Engineering Standard 942-0240 (drawings last revised 2017) instead specifies red plastic material with engraved white letters, with the 'PHOTOVOLTAIC BREAKER' label at 4" minimum letter height and other labels at 3/8" minimum. 75% · utility DG manual
• Is a site plan / facility map placard required, and what must it show? The required roof/site plan itself functions as the facility map: it must show panel layout, all hips/valleys/ridge lines, required access pathways, and the location of the meter, AC disconnect, inverters and other electrical equipment. No separate exterior 'facility map' placard beyond that plan-set requirement and the labels covered in Q38/Q43 was found. 70% · 705.10 + local
• Does the UTILITY specify placards beyond the AHJ's? Yes — LEU publishes its own Engineering Standard 942-0240 ('Generation Metering'), which specifies generation-meter labeling and AC-disconnect placement independently of the Building/Fire checklist. 85% · utility DG manual
• Where must the labels be placed? At the main electric service panel (DUAL POWER SUPPLY caution), at the PV breaker inside the panel, at the AC disconnect, at the inverter, on DC conduit/raceways at every 10 feet of run plus at turns, penetrations and combiner/junction boxes, and at the LEU generation meter. 88% · ordinance / utility spec

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? Within 10 feet of the Main Service Entrance Panel, on the same wall surface/face, with a visible open point, lockable, and accessible to the City/LEU at all times (LEU standard names 'Square D DU221RB or approved equal'). 92% · utility DG manual
• Must equipment be on a specific approved list? Yes — PV modules and inverters must be on the California Energy Commission's Eligible Equipment List, modules UL 1703-certified and inverters UL 1741/IEEE 1547-certified. 90% · utility DG manual
• Are batteries permitted, and under what conditions? Yes. Battery/energy-storage installations are allowed; SolarAPP+'s Lodi application explicitly offers a 'Solar with Battery Backup' option, and LEU requires that a battery inverter's output automatically disconnect from LEU's grid on loss of utility voltage and not reconnect until voltage is restored (LEU's Engineering Standard 942-0240 also carries a battery-backup metering diagram added in 2017). 85% · fire code + amendments
• Is there a separate ESS permit or inspection? No separate ESS permit or fee line item was found — batteries are processed within the same residential PV permit. Both the current Fire Fee Table and the (superseded) 2019 Fire Fees document were checked for a battery/ESS line and neither has one (positive control 'fire'/'permit' hit repeatedly; fabricated control 'zzqqx' returned zero hits in both). 75% · fee schedule
• Is there a local rule on service upgrades or busbar sizing? The standard 2025 CEC 705.12(B)(2) 120% rule applies: the PV breaker must be ≤20% of the panel busbar rating, or the sum of overcurrent-device ratings on the busbar must not exceed 120% of the busbar's rating; the PV breaker must be at the opposite (load) end of the panel from the main breaker. No additional Lodi-specific numeric tightening of this rule was found beyond restating the code. 85% · published checklist

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 requested through the City's eTRAKiT online system (contractor or public-user login, 'Request' under the Inspection column for the applicable permit). 85% · department page
• How much notice is required? Not a stated multi-day minimum — the eTRAKiT system 'will always default to next available business day' when a contractor or public user requests an inspection, i.e., effectively next-business-day scheduling. 65% · department page
• Are same-day or AM/PM windows offered? AM/PM windows can be selected when booking, but the guide explicitly warns such time requests 'are not guaranteed.' 75% · department page

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 90% · department procedure
• If delegated, to whom? N/A — not delegated. The City of Lodi Building Division performs its own final residential PV inspection. 90% · department procedure

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? LEU PowerClerk pre-approval -> City Building Division reviews and issues the permit (within 72 business hours of a complete application + LEU approval) -> installation -> final inspection scheduled and passed with the City Building Division -> LEU installs its solar meter (usually within 10 business days of a passed final) -> door hanger delivered and a Permission-to-Operate certificate generated by LEU. 88% · department page
• Is a rough-in or mid-roof inspection required? Not stated as a requirement — the published procedure for residential rooftop PV describes only a single final inspection step; no rough-in or mid-roof inspection is named. 65% · department procedure

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 — the City publishes a 'Residential – Photovoltaic Checklist' used at plan review, and the SolarAPP+ path separately requires an 'approved inspection checklist' to be present at the final inspection. 88% · department page
• What must be on site at inspection? The complete permit package/approved plans (standard path); for the SolarAPP+ path, the approved SolarAPP+ inspection checklist plus all product specifications approved in SolarAPP+. 88% · department page
• Does the inspector verify labels and listings? Likely yes, though not stated as an explicit inspector duty in so many words: the procedure requires the 'complete permit package,' the 'approved inspection checklist,' and 'all product specifications approved in SolarAPP+' to be on site at inspection, and the checklist itself mandates labeled/listed equipment as an approval condition. 60% · department page / practice

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? A finaled permit ('Final') in the City's own tracking/reporting categories — the City's Monthly Building Reports track permits as issued/pending/finaled, and no document states a Certificate of Occupancy is issued for adding PV to an existing single-family dwelling. 60% · department page
• Who notifies the utility for PTO? Utility pulls — Lodi Electric Utility automatically generates the Permission-to-Operate certificate (and a physical door-hanger notice) once its solar meter is installed following the City's passed final building inspection; no separate installer or homeowner request to the utility is required. Contractors retrieve the PTO document from LEU's Solar Submittal Portal; customers may request a copy by email. 88% · utility DG manual
• Is there a re-inspection fee? $178 92% · fee schedule
