Question 1

How much is a painting permit in Idaho in 2026?

Accepted Answer

Idaho typically does NOT require a building permit for painting (factor 0 in our model). No permit required for residential painting. Lead-paint RRP certification not a permit fee. You may still need a trade-specific license-confirmation; check the /contractor-licensing/painting-in-idaho page for full requirements.

Question 2

Why is the fee higher in major Idaho metros?

Accepted Answer

Each Idaho city/county sets its own multiplier on top of the state base rate. Boise runs 1.2× because of stricter plan review + structural review + energy-code overhead. Idaho Falls sits lower (0.95×) because of less plan-review depth + simpler intake. Rural counties in Idaho often have flat-fee schedules below even the lowest metro.

Question 3

What's included in the permit fee vs. what's billed separately?

Accepted Answer

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.

Question 4

Can I skip the permit and save the fee?

Accepted Answer

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. Idaho treats unpermitted painting work as a separate violation under state building code. The "savings" become a $1,500 problem at resale on a $500 fee.
