How much will your residential permit cost?
Permit fees swing more than any other line on a contractor invoice. A kitchen permit in San Francisco runs $400+; the same kitchen in rural Tennessee runs under $100. Cluster surfaces the formula (typically 1–3% of project cost, capped per-state), with top-3 metro multipliers.
Where permits eat the most budget
Statewide permit-fee model for a typical mid-range kitchen of medium scope (no metro multiplier applied). Major-metro permits inside each state run 15–35% above the statewide figure.
Highest-fee states (residential, 2026)
California (2.0%) · Hawaii (1.8%) · New York (1.7%) · New Jersey (1.6%) · Massachusetts (1.5%)
Percentage = state base × project type. Actual permit fee = base × project factor × metro multiplier × project cost, clamped to each state's min/max.

How residential permit fees actually work
Most U.S. jurisdictions calculate residential permit fees as a small percentage (1–3%) of project valuation, then add per-trade fees for plumbing/electrical/ mechanical scopes. The percentage varies by state, but the BIG multiplier is your city: a kitchen permit in San Francisco can run 60% more than the same job in Fresno — same state, same code, different fee schedule.
What's NOT a permit fee: plan-review service fees (separate line), contractor's filing fee (separate), school-tax surcharges (most California cities), and impact fees (new construction only). The permit fee on this cluster is just the building department's base intake fee for the residential work.
Skip the permit? Don't. Working without one fails any future resale inspection, voids your homeowner's insurance for related claims, and triggers retro-permit fines (often 2-3× the original fee). It's the single most common headache when selling a home that's been renovated.
Pair with the /renovation-timeline cluster for permit lead-time (CA = 6 weeks, TX = 1 week), and the /contractor-licensing cluster to verify the contractor pulling it.
