Which county handles electrical permits for 94548?
This ZIP sits in Contra Costa County, California. Permit and inspection requirements for panel changes, service upgrades and new circuits are set locally, so confirm with the contractor whether a permit is required for your specific job and who is filing it.

Is a permit needed for electrical work?
Permits are commonly required for panel replacements, service upgrades, new circuits, and work in wet locations like kitchens, bathrooms and outdoors. Simple device replacements often do not need one. Because requirements are set locally, the safest approach is to ask the contractor who will pull the permit and confirm the inspection record afterwards.

Licensed residential electricians generally charge in the $50 to $150 per hour range in 2026, plus a service call fee of roughly $75 to $200. Most companies now price common jobs flat-rate rather than hourly, which means the number you are quoted is the number you pay if the scope does not change.
