Berkeley Plumbing Guides

Plain answers on the rules, costs and decisions that come up with older Berkeley homes. Each guide shows its sources and the date we last checked it.

Short answer

These guides cover what Berkeley homeowners ask most: how to hire a plumber, how to spot an upsell, what the Bay Area water heater rule means, how to shut off your water in an emergency, and how the City of Berkeley sewer lateral rules work.

Cost guides

How we write these

Every guide links to the City of Berkeley, the Contractors State License Board, the Bay Area Air Quality Management District or another primary source where one exists. Prices are labeled as reported ranges with their source and date, not as quotes. When a rule is still being decided, we say so and update the page after the decision.
