City of Dinuba

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 page
• What does this authority permit itself, and what does it delegate? Both 95% · department page
• Is a permit required for a residential rooftop PV system? Yes 95% · ordinance
• Is there a separate electrical permit, or is it combined? Combined (single flat permit fee covering the PV installation) 68% · fee schedule
• Is a HOA or architectural approval required first? No city-imposed HOA/architectural-approval condition found 60% · ordinance
• Is there a historic-district review? No PV-specific carve-out or trigger found in the Historic Preservation chapter (DMC Ch. 14.62); the chapter is silent on solar entirely, so whether a Certificate-type review would reach rooftop PV on a designated resource is unresolved from the code text alone. 55% · ordinance
• Is a wind or windstorm certification required? No windstorm-certification requirement found 80% · ordinance
• Is a Specific Use Permit or Council approval ever required? Not for a standard residential rooftop system. Zoning defines 'Solar energy system' (on-site use) as a Permitted (P) use across the residential/commercial/industrial use matrices; only a 'Solar electricity generating plant' (commercial-scale, feeding the grid) requires a Conditional Use Permit in some districts. 85% · ordinance
• Is there a system-size cap on residential generation? No numeric cap is restated in the local ordinance; DMC Ch. 14.70 scopes itself to systems meeting 'SB 379 size thresholds, as defined in California Government Code Section 65850.5' by reference only, without repeating the kW figure in the city's own text. 65% · ordinance

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 70% · checklist
• Must the contractor be registered with this authority before applying? Yes 85% · department page

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? Cover sheet (electrical/PV construction notes, site plan, code compliance notes, contractor info), Site Plan, Roof Plan, Attachment Layout, Calculations (system/wire/120% rule), Single Line Diagram, Code-Required Signage/Labels sheet, manufacturer spec sheets and UL listing, and a photo of the existing meter panel breakers/dead-front. 95% · checklist
• How many copies, and in what format? Minimum of two complete plan sets, on 11x17 paper 95% · checklist
• Is a site plan required, and what must it show? Yes — property lines/fences, streets/alley, buildings, pool, PV module layout, main panel/inverter location, trees, and other roof equipment (vents, skylights, HVAC). 95% · checklist
• Is a one-line / three-line diagram required? Yes 95% · checklist
• Are string and conductor calculations required? Yes 95% · checklist
• Is a structural PE stamp required, and at what threshold? No numeric roof-mount PE-stamp threshold is codified; ground-mounted PV 'placed on a support system' must be engineer-designed regardless of size. The city's own 'workbook' handout that would normally carry a customized structural-criteria threshold is, in fact, the un-customized statewide 2017 California Solar Permitting Guidebook/Toolkit, with the drafting instruction 'introductory text provided for jurisdiction's reference only — do not attach to Criteria that follow' still present on p.60 — i.e. Dinuba never filled in its own threshold. 55% · checklist
• Is an electrical PE stamp required, and at what threshold? No distinct electrical PE-stamp threshold stated; plans may be signed by a licensed contractor (A/B/C-46/C-10) or by a licensed electrical engineer, per the checklist — the engineer route is offered as an alternative to a contractor's signature, not gated by a system-size threshold. 60% · 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? SolarAPP+ (gosolarapp.org) for automated plan review, feeding into the city's own eSuite e-permit portal (esuite.dinuba.org) for permit issuance and payment. 95% · portal landing page
• Can the whole application be completed online? Yes 88% · portal
• What does a residential solar permit cost? $408 flat (Building permit line, FY26/27) 92% · fee schedule
• How is the fee calculated? Flat 92% · fee schedule
• Is there a separate plan-check fee? Yes, on the fire side — a separate Fire Department 'PV/ESS System Plan Review' fee of $400 exists distinct from the $408 Building permit fee; there is no separate Building plan-check line item for solar itself (the $408 appears to be a single bundled fee, consistent with the other flat 'Project/Other' items in the same table). 80% · 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? Generally 5 business days for the initial completeness review; final action follows the statutory timelines of Gov. Code §65850.5. 88% · ordinance
• How long is an issued permit valid before it expires? 180 days from issuance, with one discretionary 180-day extension available on written request before expiration (further 90-day extensions possible for documented circumstances beyond the applicant's control). 88% · ordinance
• Which utility handles interconnection here? PG&E (Pacific Gas & Electric) 88% · checklist
• Where does the utility sit in the sequence? After permit / parallel-but-gated at energization: the city's own checklist states systems 'shall not be energized until the final inspection has been approved by the Building Inspector,' and PG&E's own Rule 21 (§D.13.b) processes NEM/PTO only upon receiving evidence of the applicant's final AHJ electrical-inspection clearance. 78% · checklist

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 95% · adopting regulation
• Which building code edition is in force? 2025 California Building Code (based on the 2024 IBC), adopted by Ord. 2025-04 95% · adopting regulation
• Which fire code edition is in force? 2025 California Fire Code (based on the 2024 IFC), Ord. 2025-04 with amendments from Ord. 2023-01 95% · adopting regulation
• Are there local amendments to any of the above? Yes, in Building (Appendix H/I/J adopted; permit-expiration/refund amendments), Residential Code (§R105.2 exemptions, Table R302.3.6, §R318.1 egress) and Fire Code (address ID, apparatus-road dimensions, cost-recovery, sprinkler thresholds). Electrical Code and WUI Code amendments are both explicitly 'Reserved' — no local amendments to either. 88% · ordinance
• What is the installation judged against? The 2025 CBC/CRC (incl. CRC §324, unamended), 2025 CEC (2023 NEC, Art. 690/705, unamended), and 2025 CFC — the current, codified editions. The city's own 2019 PV checklist and Roof-Access letter are stale, still citing the 2016 CEC/CFC and 2013 CEC Art. 690/705 — two cycles behind current law. 82% · ordinance

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? Conduit (interior or exterior) may not run within 3 ft of the ridge and, if in the attic, must be kept away from the ridge and secured to load-bearing members. Fire-access pathway/ridge setbacks follow the state's 1 Jul 2018 revision: 18 in. from valleys, and ridge-ventilation setback relaxed from 36 in. to 18 in. where PV covers <1/3 of the roof plan area (or <2/3 with sprinklers); one 3-ft pathway on hip roofs, two 3-ft pathways on single-ridge roofs; 36-in. pathway required under windows. 82% · checklist

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. Current electrical adoption is the 2023 NEC (unamended locally), so NEC §690.12 applies as written. The city's own 2019 checklist still references 'CA Electrical Code Article 690 & 705' generically (2016/2013-cycle) without citing §690.12 by number. 72% · ordinance

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? Warning labels on main panel, inverter and disconnect boxes; Shock Hazard Warning labels on inverter/main panel/disconnect boxes; a Rapid Shut-Down label; 'Panel Fed by Multiple Sources' labels on main panel, inverter and sub-panel; completed DC and AC Disconnect 'Photovoltaic Power Source' labels; and a permanent plaque/directory where the main disconnect and DC/AC disconnects are not co-located. 90% · checklist
• Does the authority specify placard wording of its own? No independent verbatim wording beyond the standard code-required label content (e.g. the standard NEC/CFC 'Photovoltaic Power Source' disconnect labels) — no Manhattan-Beach-style custom sample sheet found. 62% · checklist
• Is a site plan / facility map placard required, and what must it show? A permanent plaque or directory is required whenever the main service disconnect and the DC and/or AC PV disconnects are not in the same location — functioning as the local implementation of the NEC §705.10 directory requirement. No separate site-plan/facility-map placard beyond this is specified. 82% · checklist
• Does the UTILITY specify placards beyond the AHJ's? PG&E's own Rule 21 (§H.1.d, 'Visible Disconnect Required') independently requires a visible, lockable disconnect reachable 24/7 with open/closed markings, shown on the single-line diagram — beyond whatever the AHJ requires. This is PG&E's general tariff rule, not a Dinuba-specific citation. 68% · utility tariff
• Where must the labels be placed? On the junction box, inverter, DC and AC disconnects, sub-panel, and main electrical panel. 90% · checklist

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.

• Must equipment be on a specific approved list? Yes — UL listing 85% · checklist
• Are batteries permitted, and under what conditions? No Dinuba-specific ESS/battery ordinance found; batteries would be governed entirely by the unamended 2025 CFC/CRC battery-storage provisions. The only 'battery' hits in the whole of Title 14 concern a Group F-1 (manufacturing) sprinkler trigger for lithium battery/EES manufacturing occupancies, not residential installation conditions. 68% · ordinance
• Is there a separate ESS permit or inspection? No distinct separate ESS permit process was found; the Fire Department's fee schedule bundles PV and ESS plan review into one line item ('PV/ESS System Plan Review,' $400), suggesting they are processed together rather than as two separate permits. 60% · fee schedule
• Is a ground mount treated as a structure? Yes, functionally — a ground-mounted PV system 'placed on a support system' must be designed by a licensed engineer, per the checklist, the same treatment given to an engineered structure. 75% · checklist
• Is there a local rule on service upgrades or busbar sizing? No local busbar/service-upgrade amendment exists — DMC §14.20.020 (Electrical Code amendments) reads 'Reserved.' 85% · ordinance
• Is a specific mounting system or attachment spacing required? No numeric standoff/spacing standard is codified; the checklist requires attachment details, rail/point-support layout, and roof-load/point-load calculations at submittal, relying on manufacturer engineering rather than a city figure. 58% · 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? Phone 95% · department page
• How much notice is required? 1 business day — call by 4:00 pm for next-day inspection; calls after 4:00 pm are scheduled for the 2nd day following the call. (Effective 1 Apr 2026, per the city's own page.) 95% · department page
• Are same-day or AM/PM windows offered? AM/PM preference may be requested but is not guaranteed. 92% · 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 93% · department page
• If delegated, to whom? N/A — self-performed, not delegated 90% · 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? One inspection is required for a standard roof-mounted PV system; if a new Main Electrical Service Panel is also installed, that is a separate inspection performed in addition. 88% · checklist
• Is a rough-in or mid-roof inspection required? No — a separate rough-in/mid-roof inspection is not required for a standard roof-mount system; only the single final PV inspection (plus a separate inspection if the MSP is upgraded). 78% · checklist

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 95% · checklist
• What must be on site at inspection? Approved plans and the permit on site; the property owner present (to test smoke/CO alarms); a ladder to access the roof; and all equipment/disconnects/junction boxes open and accessible (with covers removed) for inspection. 93% · checklist
• Does the inspector verify labels and listings? Yes 93% · checklist

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 (permit closure on a passing final inspection) 75% · ordinance
• Who notifies the utility for PTO? Installer (inferred) 62% · utility tariff
• Is there a re-inspection fee? $194 (general Building 'Inspection/Re-Inspection Fee', FY26/27) 72% · fee schedule
• How are corrections issued and cleared? One written correction notice identifying all deficiencies is issued at the completeness-review stage (DMC §14.70.040); at final inspection, any deficiency found must be corrected to the city's satisfaction before the permit can be closed (DMC §14.70.070.C); plan revisions/addenda must be marked with a circling cloud and an explanation per the checklist. 88% · ordinance
