Solar permits in Marin: by jurisdiction.
Every Marin city and the county handle solar permits differently. Some use SolarAPP+ for instant issuance; others use traditional plan review. Here's the breakdown.

Solar permits in Marin range from same-day SolarAPP+ instant approvals to 2-4 week traditional plan reviews depending on jurisdiction. Marin County, San Rafael, Novato, and several other jurisdictions have adopted SolarAPP+ for standard residential solar (under specific size and complexity limits). Permits typically cost $200-$600 depending on system size and jurisdiction. Electrical-only permits (for panel upgrades preceding solar) are separate from solar permits, $80-$200 typically.
01How SolarAPP+ changed Marin permitting.
SolarAPP+ (Solar Automated Permit Processing Plus) is a federally-funded tool that enables jurisdictions to issue solar permits automatically for standard residential systems that meet predefined criteria. Once a jurisdiction adopts SolarAPP+, qualifying systems can receive permits within hours of application — sometimes same-day. As of 2026, Marin County, San Rafael, Novato, Mill Valley, and several other Marin jurisdictions have adopted SolarAPP+ for residential solar. The criteria vary slightly but generally cover systems up to ~15kW DC with standard configurations.
Systems exceeding SolarAPP+ criteria — larger arrays, ground-mount, battery integration with specific configurations, atypical electrical setups — fall back to traditional plan review. Plan review timeline 2-4 weeks for solar permits. The reviewer evaluates the electrical design (one-line diagram, panel calculations, conduit and conductor sizing), the structural design (roof load), and code compliance. Traditional review costs slightly more in jurisdiction fees and requires more documentation upfront.
02Marin jurisdiction summary.
SolarAPP+ jurisdictions (2026)
Marin County (unincorporated), San Rafael, Novato, Mill Valley, Sausalito, and several others. Instant or same-day approvals for qualifying residential solar. Confirm current status with jurisdiction or via SolarAPP+ website at time of application.
Traditional plan review
Some smaller jurisdictions still use traditional plan review for all solar applications. Plan review 2-4 weeks, in-person or online submission, may require additional documentation (structural calcs, electrical one-lines).
Battery-included systems
Most Marin jurisdictions have specific requirements for energy storage systems (UL 9540, fire setbacks, signage). SolarAPP+ covers some battery configurations; others go through traditional review. Plan accordingly during scope definition.
03Where electrical permits intersect solar permits.
Solar permits cover the solar electrical scope (interconnection breaker, AC disconnect, equipment grounding, conductors from inverter to panel, signage). They don't typically cover preceding electrical work — like panel upgrades needed before solar can interconnect. That electrical work needs a separate electrical permit, pulled before solar installation begins. Timing matters: panel upgrade permit + work + inspection typically completes 2-3 weeks before solar permit is pulled.
For homeowners managing solar through one contractor (solar contractor with in-house electrical), all permits go through that contractor. For split scope (homeowner hires us for panel upgrade + a solar-only contractor), we pull the electrical permit for our scope and the solar contractor pulls the solar permit for theirs. Inspections are separate; close-out timing coordinates. Most Marin jurisdictions are familiar with the split-scope pattern and accommodate it without complications.
Common questions.
How fast can I get a solar permit in Marin?
In SolarAPP+ jurisdictions for qualifying systems: same-day to 1-2 days. In traditional plan review: 2-4 weeks. Most residential solar in Marin (under 15kW, no unusual configuration) qualifies for SolarAPP+ in the SolarAPP+-adopting jurisdictions. Check with the solar contractor or jurisdiction directly for specific timeline expectations.
Do I need a permit for solar?
Yes — solar electrical work always requires permits in California. The permit ensures the work meets code, is inspected by qualified inspectors, and is properly documented. Unpermitted solar work creates problems for: (1) PG&E interconnection (PG&E requires inspection sign-off), (2) home sale disclosure, (3) homeowner insurance, (4) warranty claims. Permits are inexpensive insurance against significant downstream issues.
Who pulls the permits?
Standard scope: the solar contractor pulls the solar permit; the electrical contractor pulls any panel upgrade permit. Solar contractors with in-house electrical handle both. If a homeowner hires multiple contractors, each pulls permits for their scope. Permits are tracked and inspected separately but coordinate through the jurisdiction.
What if my permit application is rejected?
Rare for residential solar. If rejected, the jurisdiction provides reasoning (typically design issues, missing documentation, or code compliance questions). The solar contractor or electrical contractor addresses the issues and resubmits. Most rejections resolve within 1-2 weeks. For SolarAPP+ rejections, the system reverts to traditional plan review where reviewer feedback is provided.
How do you handle pricing — flat fee or hourly?
Both, depending on scope. Routine service calls and predictable scope (panel replacement, EV charger install, transfer switch install, fixture replacement) are flat-fee quoted up front. Diagnostic visits and emergency scope are hourly because we don't know what we'll find. Either way, you get a written quote before work starts on anything significant, and we don't proceed beyond the quote without your sign-off.
How quickly can you schedule?
Depends on scope and season. Emergency dispatch: same-day across Marin County (1-3 hours business hours, 1-4 hours after-hours). Same-day standard service: 3-6 hours from call when capacity allows; otherwise next business day. Scheduled service work: 1-3 weeks typical. Larger projects requiring permits and PG&E coordination: 4-12 weeks depending on scope. We're upfront about timeline at the quote stage.
What warranty do you offer on work?
Our standard residential warranty: 2 years on labor, manufacturer warranty on parts (varies by product — typically 1-10 years). Major installs (panels, generators, EV chargers) often have longer manufacturer warranties (5-10 years). If there's an issue with our work in the warranty period, we come back and fix it at no cost. We also stand behind work past warranty — repeat customers and referrals matter more than a transactional fix.
