Boise Home Remodel Permits Explained: What You Need and How to Get Them

Quick answer

Almost certainly. The City of Boise's Homeowner's Guide states that plumbing permits are required for most bathroom remodels when fixtures are replaced, and that a building permit is required if the project removes wall coverings to expose framing, builds or moves a wall, or relocates sinks, tubs, showers or water closets.

Frequently Asked Questions

Do I need a permit to remodel my bathroom in Boise?

Almost certainly. The City of Boise's Homeowner's Guide states that plumbing permits are required for most bathroom remodels when fixtures are replaced, and that a building permit is required if the project removes wall coverings to expose framing, builds or moves a wall, or relocates sinks, tubs, showers or water closets. Adding or replacing a bath exhaust fan also needs a mechanical permit. Re-tiling a surface without touching concealed plumbing or framing is exempt. When in doubt, call the Boise Building division at (208) 608-7070.

How much does a building permit cost in Boise?

Boise calculates the building permit fee from the declared project valuation using Table 1-A of its adopted Building Code Fee Schedule: $70.76 plus $12.71 per $1,000 above $2,000 up to $25,000; $362.80 plus $9.30 per $1,000 up to $50,000; $595.30 plus $6.35 per $1,000 up to $100,000; and $913.09 plus $5.17 per $1,000 above that. Residential plan review adds 20% of the permit fee. Trade permits are separate and are charged per fixture — plumbing is $30 plus $12 per fixture, mechanical $32 plus $12 per appliance, and electrical is $110 flat when more than one fixture is involved in an alteration.

How long does it take to get a building permit in Boise?

Boise PDS publishes its actual performance every quarter. In the 1 June to 31 August 2026 report, residential additions, alterations and repairs at Level 1 averaged 1 business day to first review against a target of under 1 day, and Level 2 averaged 8 business days against a target of under 10. Average time to "ready to issue" was 8 days for Level 1 and 28 days for Level 2 — the gap is correction cycles, which is the part application completeness controls. Check the current report on the Building division page before scheduling.

Can I pull my own permits in Boise as a homeowner?

Yes, with a condition Boise states plainly: homeowners may work on their primary residence without registering as a contractor, but if a permit is required and you act as the sub-contractor, you must pull the permit and physically perform the work yourself. If someone else does the electrical, plumbing or mechanical work, that person must be an Idaho-registered and licensed contractor in that trade. Homeowners can apply online through the city's Permitting and Licensing System for trade permits and for fence, roof, window and siding permits.

What happens if I remodel without a permit in Boise?

Boise's adopted fee schedules charge a special investigation fee equal to 100% of the permit fee, in addition to the original permit fee, for work that commences before the permit is issued — so the permit effectively doubles. Beyond the fee: stop-work orders that halt construction, opening finished walls so the work can be inspected, disclosure obligations and appraisal problems at resale, and personal liability for injuries. The permit itself is a small number by comparison.

Does replacing a water heater require a permit in Boise?

Yes. Boise's Homeowner's Guide lists "install or replace a water heater" under plumbing permits, for both tank and tankless units. Under the city's plumbing fee schedule, installing a single fixture or appliance such as a water heater is a $55 flat fee. The permit exists to confirm gas venting, temperature and pressure relief valve discharge, expansion tank and electrical connections.

Do I need a permit to replace windows in Boise?

Yes. This is one of the most commonly misstated rules online. The City of Boise lists "new, replacement windows or door openings, widen or reduce the size of existing openings" under Building Permits — a like-for-like replacement is not exempt. Boise's online permitting system lets homeowners pull window permits directly, and replacement windows must comply with the City of Boise Window Replacement Policy. In a historic district, windows also require a Certificate of Appropriateness from the Planning division before you apply for the building permit.

Are permits different in Meridian vs Boise?

Yes. Both cities apply Idaho's adopted building codes, but they run separate permit offices, separate online portals and separately adopted fee schedules. Boise uses its Permitting and Licensing System (Accela Citizen Access) with ePlanReview for drawings; Meridian uses its own Accela Citizen Access portal with ProjectDox. Accounts and permits do not transfer between them. Make sure your contractor has worked in the specific city where your home is located.
