Frequently Asked Questions

Do I need an electrical panel upgrade for an EV charger or heat pump?

Not necessarily. We assess existing demand, circuit space, equipment condition and the new load. The result may be a dedicated circuit, compatible load management, or a panel and service upgrade. A 200-amp panel is not a universal requirement.

What affects the cost of electrical work in Mill Valley?

Price depends on the type of repair or installation, how easy the wiring is to reach, the equipment, and any meter, utility, permit or patching work. We assess the project and explain exactly what the estimate includes.

How do permits work for electrical projects in Mill Valley?

Mill Valley lists panel, main-service and subpanel work in its permit process. EV chargers and batteries have their own requirements. Confirm whether the address is within the City or unincorporated Marin. See Mill Valley electrical permit process.

Does an older Mill Valley home need rewiring?

Not always. Tell us which rooms are affected, what work was added in earlier remodels and whether you have plans or records. That lets us assess the existing circuits and the proposed work together instead of assuming the whole house needs rewiring.
