Many home remodeling projects in Boise and Ada County require one or more permits. Below are the most common permit types and when they apply.
Building Permit
Required for structural work, additions, wall removal or relocation, and major renovation projects. The City of Boise Planning and Development Services department reviews plans and issues permits.
Most kitchen and bathroom remodels, basement finishing, deck construction, and additions.
Electrical Permit
Required when adding new circuits, relocating panels, installing new outlets or fixtures, or upgrading wiring. Must be performed by a licensed electrician.
Kitchen remodels with new circuits, panel upgrades, basement finishing, and ADU construction.
Plumbing Permit
Required for new plumbing installations, fixture relocations, water heater replacements, and sewer line work. Must be performed by a licensed plumber.
Bathroom remodels with fixture relocation, kitchen sink moves, and new bathroom additions.
Mechanical Permit
Required for HVAC system installations, ductwork modifications, furnace replacements, and ventilation work. Idaho requires licensed HVAC contractors.
Basement finishing, additions, ADU construction, and whole-home renovations.
Some cosmetic and maintenance projects typically do not require building permits in Boise. However, requirements can change, so always verify with your contractor.
Important: Even cosmetic projects may require permits if they involve changes to electrical, plumbing, or structural elements. Iron Crest Remodel always verifies permit requirements before starting any project.
Boise's zoning regulations affect what you can build, how large it can be, and where it can be placed on your property. Understanding these requirements is essential for additions, ADUs, and significant exterior modifications.
Setback Requirements
Boise zoning codes specify minimum distances from property lines for structures, decks, fences, and additions. Setbacks vary by zone classification and must be verified before design.
Height Restrictions
Maximum building heights are determined by your property's zoning designation. Additions, second stories, and ADUs must comply with height limits.
Lot Coverage Limits
Zoning codes limit the percentage of your lot that can be covered by structures. This affects the size of additions, detached garages, and ADU construction.
Accessory Dwelling Units (ADUs)
Boise allows ADUs in many residential zones. Specific requirements for size, parking, owner-occupancy, and utility connections apply. Check current ADU regulations before planning.
Historic District Requirements
Properties in Boise's historic districts (North End, Warm Springs, and others) may require additional design review and approval from the Historic Preservation Commission.
HOA Restrictions
If your home is in a subdivision with a homeowners association, additional design guidelines and approval processes may apply beyond city requirements.

How long does it take to get a building permit in Boise?
Standard residential building permits in Boise typically take 2–4 weeks for review and approval. Simple permits (like deck construction) may be approved in 1–2 weeks. Complex projects involving variances, zoning exceptions, or historic district review can take 6–12 weeks. Iron Crest Remodel submits permit applications immediately after contract signing to minimize delays.
How much do building permits cost in Boise?
Building permit fees in Boise are based on project valuation. Typical residential remodeling permits range from $200–$1,500 depending on scope. A kitchen remodel permit might cost $400–$800, while a major addition could be $1,000–$2,500. Electrical, plumbing, and mechanical permits are separate and typically $100–$400 each. All permit costs are included in Iron Crest estimates.
What happens if I remodel without a permit?
Unpermitted work in Boise can result in fines, mandatory removal of completed work, difficulty selling your home, insurance claim denials, and code violation liens. The City of Boise has an active code enforcement division. If you discover previous unpermitted work, we can help navigate the retroactive permitting process.

Yes. Iron Crest Remodel manages the entire permitting process as part of our full-service remodeling. We prepare permit applications, submit plans, coordinate with city reviewers, schedule all required inspections, and ensure final approval. Permit management is included at no extra charge in all our project contracts.
What inspections are required during a remodel in Boise?
Common inspections include rough framing, rough electrical, rough plumbing, rough mechanical (HVAC), insulation, and final inspection. Bathroom remodels typically require plumbing rough-in and final inspections. Kitchen remodels with new circuits need electrical inspection. Iron Crest schedules all inspections and is present for every one to ensure smooth approval.
