FAQ — Bathroom permits in California
How much is a bathroom permit in California in 2026?
On a typical $15,000 bathroom project in California, the statewide median permit fee runs $360 — about 2.40% of project cost. Major metros run higher: San Francisco $576, Los Angeles $504, Fresno $378. Highest permit fees in the U.S. SF + LA + San Diego all add Title 24 energy-review + structural-review surcharges. Coastal Commission review adds $500-$2k where applicable.
Why is the fee higher in major California metros?
Each California city/county sets its own multiplier on top of the state base rate. San Francisco runs 1.6× because of stricter plan review + structural review + energy-code overhead. Fresno sits lower (1.05×) because of less plan-review depth + simpler intake. Rural counties in California often have flat-fee schedules below even the lowest metro.
What's included in the permit fee vs. what's billed separately?
The permit fee covers the building department's intake + base review. NOT included: plan-review service fees (often a separate line, 0.5–1% of project cost), per-trade fees for plumbing/electrical/mechanical (typically $50–$200 each), and any state-level surcharges (FL adds DBPR 1.5%, NJ adds DCA, OR adds 12% BCD surcharge). Your contractor's filing fee is also separate. Budget 1.5–2× the base permit fee for the all-in cost.
Can I skip the permit and save the fee?
Don't. Working without a required permit fails any future resale inspection (the buyer's inspector WILL flag it), voids your homeowner's insurance for any related claim, and triggers retro-permitting fines that are typically 2–3× the original fee. California treats unpermitted bathroom work as a separate violation under state building code. The "savings" become a $1,500 problem at resale on a $500 fee.
