Accessory dwelling unit electrical — service feed, subpanel, full circuits, code-compliant. In Novato, CA: Novato's housing skews newer than southern Marin — significant tracts built 1965-1990, plus the Hamilton redevelopment (former Hamilton AFB, mostly built 2000-2010). 100A service is common in pre-1985... Typical pricing: $4,500-$18,000. Duration: 1-3 weeks. C-10 licensed (CSLB #989290), PG&E-coordinated, permit-pulled where required.
01Why adu electrical in Novato is its own thing.
Marin County's northernmost city, Novato spans 28 square miles from the bayshore at Hamilton to the rural fringe at Black Point. The electrical work that happens here reflects what makes the area distinct. ADU electrical has its own code chapter (NEC 210-220 plus state amendments). Service feed sizing and panel selection are the early decisions that constrain everything else.
Common drivers we see for adu electrical work in Novato: ADU new construction, garage conversion to dwelling, existing structure conversion, granny unit build, rental income unit, family multigenerational setup. Each creates a different scope conversation — we walk every project before quoting so the number reflects the actual work.
02What working here actually looks like.
Geography matters more here than people often realize. Flat bayshore east; rolling hills west; rural valleys at Indian Valley and Black Point. Service drops are predominantly overhead in older neighborhoods, underground in Hamilton.
Utility grid context: PG&E's Novato grid handled significant load growth from Hamilton's redevelopment in the early 2000s — the area has solid distribution capacity, but western Novato (San Marin, Indian Valley) sees more frequent PSPS events during fire weather.
Permit jurisdiction for this scope: City of Novato Building Division for incorporated areas; Marin County Permits for unincorporated areas (Black Point, parts of Indian Valley). Permit fees: $200-$500 typical for residential electrical work.
03How a adu electrical project here goes.
Typical adu electrical project in Novato runs 1-3 weeks from kickoff to final inspection. Pricing range: $4,500-$18,000, with variation driven by access, existing conditions, and permit complexity.
The sequence we follow: Service feed planning (sub-panel feed from main vs separate service) → Load calc for new dwelling unit → Conduit run + service install → Full ADU rough-in (circuits, devices, fixtures) → AHJ inspection + utility coordination.
We pull permits as part of the standard scope on permitted work, coordinate AHJ inspections, and don't leave site until the work is functional, tested, and signed off.
