FAQ — Bathroom permits in Maine
How much is a bathroom permit in Maine in 2026?
On a typical $15,000 bathroom project in Maine, the statewide median permit fee runs $216 — about 1.44% of project cost. Major metros run higher: Portland $270, Bangor $216, Augusta $194. Portland uses ICC × 1.15; rural towns often have no permit fee for residential under $5k value.
Why is the fee higher in major Maine metros?
Each Maine city/county sets its own multiplier on top of the state base rate. Portland runs 1.25× because of stricter plan review + structural review + energy-code overhead. Augusta sits lower (0.9×) because of less plan-review depth + simpler intake. Rural counties in Maine 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. Maine 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.
