Sub-Panel Installation in Hillsborough

Permits in Hillsborough go through the Town of Hillsborough Building Division, which typically processes EV charger applications in 5–14 business days. We submit the load calculation per NEC 220.87, panel schedule, and one-line diagram with every application — getting most installs approved on the first review. We schedule the final inspection on your behalf and you don't need to be home for it.

Hillsborough sits in one of the highest EV-adoption markets in the country, with high EV penetration and growing fast. Exclusive unincorporated enclave — no commercial zoning allowed. Large estate lots (avg 1 acre+). Ultra-high income (one of wealthiest towns in US). Multiple high-end EVs per home common. 200A–400A panels standard. Long trench runs for detached garages. Town building dept is small but professional. The local utility, PG&E, offers EV-specific time-of-use rates that cut overnight charging costs roughly in half — most ChargeWizards customers in Hillsborough pay about $0.30–$0.40/kWh during off-peak hours, or roughly $1.20 per gallon-equivalent for an EV.

ChargeWizards has installed sub-panel installation in homes across Hillsborough — from single-family estate homes with 200A 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.
