EV charger permits — required, fast, worth it.
Every permanent EV charger install in California requires an electrical permit and inspection. Typical Marin AHJ processes the permit in 1-3 business days. Inspectors check load calc, conductor sizing, GFCI/AFCI, grounding, and labeling.

California requires electrical permits for all permanent EV charger installations. Marin AHJ permit timeline: 1-3 business days for issuance, same-week scheduling for inspection. Permit fee: $185-$320 typical. We handle permit application as part of every install — never optional, never expensive, always worth doing.
01Why permits matter for EV charging.
EV chargers draw continuous high current (40-48 amps continuous, vs typical household loads at 10-20A intermittent). At that current level, undersized conductors get hot, undersized breakers fail to trip on faults, missing GFCI creates shock hazard, and improper grounding amplifies any fault current. Permit and inspection catch these problems before they cause fires or injuries.
Beyond physical safety: unpermitted EV charger installs create insurance problems (carrier may deny EV-related claims), sale problems (disclosure requirements vary but a savvy buyer's inspector will flag missing permits), and code compliance issues for any future electrical work. The permit costs $185-$320 — minimal vs the potential downstream costs of skipping it. We never install without permit.
02What the inspector checks.
Load calc documentation
Inspector wants to see the NEC 220.83 load calc proving the panel supports the new EV circuit. We document this and provide at inspection.
Conductor sizing (NEC 625.42)
Conductor size must be 125% of continuous EV load. 40A continuous = #8 AWG copper minimum, 48A continuous = #6 AWG copper minimum. Inspector checks visible portions of the conductor.
Breaker rating and AFCI/GFCI
Breaker sized at 125% of continuous load (NEC 625.42). GFCI protection required for receptacle-based installs in garage and outdoor locations (NEC 625.54). Hardwired installs in dry locations don't require GFCI.
Disconnect and labeling
EV circuit clearly labeled at panel. For installs over 50A, disconnect within sight may be required depending on AHJ interpretation. Working clearances around panel verified.
Grounding and bonding
EV circuit must have proper equipment grounding conductor. Charger chassis bonding verified. For metal-conduit installs, conduit must be properly bonded.
03Marin AHJ permit fees and timing.
| AHJ | EV permit fee | Inspection timing |
|---|---|---|
| Novato | $185-$240 | 3-5 business days |
| San Rafael | $220-$280 | 3-5 business days |
| Mill Valley | $240-$320 | 5-7 business days |
| Larkspur / Corte Madera | $220-$280 | 3-5 business days |
| Tiburon / Belvedere | $260-$340 | 5-7 business days |
| Marin County (unincorporated) | $200-$260 | 5-10 business days |
Common questions.
Can I install the EV charger first and pull the permit later?
Technically yes (retroactive permitting), but we don't recommend it and don't operate that way. Permit application before install is the standard process. Retroactive permits typically require more documentation, sometimes require uncovering installed work for inspector review, and indicate to the AHJ a contractor who's cutting corners. We pull permits before every install — it's the legitimate process and adds no meaningful delay to the project.
What happens if I don't get a permit?
Several downsides accumulate. Insurance carriers may deny claims for fire or electrical damage if the EV install wasn't permitted. Home sale disclosure typically asks about unpermitted electrical work. Future electrical work (any contractor working on the panel) may flag and refuse to proceed without remediation. AHJ enforcement (rare but possible) can issue stop-work or require remediation. The $185-$320 permit fee is trivial compared to any of these downsides.
Will my install pass the first inspection?
Almost always — our first-time pass rate on EV inspections is over 97%. We build to inspector expectations: proper load calc documented, conductor sizing verified, GFCI where required, clear labeling, accessible work. The rare failures are typically minor (a missing label, a documentation gap) and corrected within 1-2 business days for re-inspection. Failed inspections are unusual for installs done by EV-specialty electricians; more common for installs by generalists unfamiliar with the EV-specific code requirements.
Are there permit-exempt installs?
Generally no for permanent installs. California requires permits for all new electrical circuits, all new outlets, and all new hardwired equipment connections — which covers every permanent EV charger install. Truly exempt scenarios: using a Level 1 portable charger plugged into an existing standard outlet (no new electrical work), or using a Tesla Mobile Connector plugged into a previously-installed NEMA 14-50 outlet (no new electrical work, the outlet install would have required permit at the time). For any new circuit or outlet installation: permit required.
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.
Are you licensed and insured?
Yes. California State License Board C-10 Electrical Contractor #989290, in good standing. Carry general liability insurance and workers' compensation insurance as required by California law. Bondable on projects requiring it. Happy to provide proof of insurance to clients or property managers on request. License lookup: cslb.ca.gov.
