Trenching & Conduit Installation in San Francisco

Permits in San Francisco go through the San Francisco Department of Building Inspection (DBI) (DBI). DBI's electrical division reviews every EV charging install — typical timelines run 3–8 weeks depending on whether the building is a single-family Victorian, a TIC, or a condo with shared electrical. ChargeWizards handles the entire DBI submission, including the load calculation per NEC 220.87, the panel schedule, and the inspection request. As a Tesla Certified Installer (CSLB #1134931), we know which inspectors expect what.

San Francisco sits in one of the highest EV-adoption markets in the country, with high EV penetration and growing fast. Most complex market. Victorian and Edwardian buildings (60A–100A panels). High percentage of condos and apartments (HOA/landlord approval needed). Steep hills complicate conduit routing. DBI permit process can be slow (6–12 weeks). CleanPowerSF has its own rebate program. Parking garages often need EVSE. Many TIC (tenancy in common) buildings complicate ownership. The local utility, PG&E, offers EV-specific time-of-use rates that cut overnight charging costs roughly in half — most ChargeWizards customers in San Francisco pay about $0.30–$0.40/kWh during off-peak hours, or roughly $1.20 per gallon-equivalent for an EV.

ChargeWizards has installed trenching & conduit installation in homes across San Francisco — from condos and apartments with 60A panels to newer construction with 200A service. Every install includes a free pre-quote panel assessment (so we never quote a panel upgrade you don't need), the city permit, dedicated 240V circuit, mounting, commissioning with the charger app, and final inspection coordination. Our owner is on every job — no subcontractors, no rotating crews. CSLB C-10 #1134931, fully licensed and insured.
