San Mateo has some of the Peninsula's most established neighborhoods — and with them, some of its oldest electrical systems. McLaren Electric helps San Mateo homeowners, landlords and businesses bring aging wiring and panels up to today's standards, with permits and city inspection handled from start to finish.
Federal Pacific panels and old fuse boxes still turn up in San Mateo homes and rentals. We replace them with modern breaker panels and coordinate the city inspection and meter release.

Learn More →Adding an EV charger to an older San Mateo home usually starts with a load calculation. If the panel can't support it, we plan the upgrade and the charger together.

Learn More →Many San Mateo properties were wired long before EV chargers, heat pumps and today's kitchens. It's common for us to find knob-and-tube wiring, obsolete Federal Pacific panels, fuse boxes and subpanels tucked inside closets — equipment that no longer meets code or insurance expectations.
Duplexes and small multifamily buildings add another layer: separate meters, shared service equipment and tenants who need the work done efficiently. On our recent San Mateo duplex project, we rewired the building, replaced both the Federal Pacific panel and the fuse box, and moved a closet subpanel to an accessible location with the required working clearance.
Panel and service work in San Mateo is permitted through the City of San Mateo and inspected before the utility restores power. We handle the permit, the inspection and the meter release so owners don't have to.
Yes. We remove knob-and-tube wiring and replace it with modern grounded circuits in single-family homes, duplexes and small multifamily buildings, and we can combine it with a panel upgrade when the service also needs attention.
Yes. Insurers often flag Federal Pacific and Zinsco panels and fuse boxes. We replace the equipment under a permit, and the final city inspection gives you documentation that the work was completed and approved.
Yes. Panel upgrades, rewiring and EV charger installations are permitted and inspected through the city. We schedule the inspection and coordinate the meter release with the utility.
