Montana uses statewide adopted construction codes with local certified enforcement. Montana uses a statewide building-code framework administered through the Montana Department of Labor & Industry Building Codes Program, with local certified building departments enforcing within their jurisdictions. Butte-Silver Bow’s building page lists the 2021 IBC, IRC, IEBC, IECC, IMC, IFGC, IFC and ISPSC and the 2021 UPC as its adopted codes; the state moved to the 2024 codes and the 2023 NEC on 26 September 2026, so confirm with the office which edition applies to your filing. Projects outside a certified local building program may require Montana DLI building, electrical, plumbing, mechanical, elevator, boiler, or specialty permits, while local governments still control zoning, subdivision, floodplain, septic, road access, fire, and development approvals.

Butte-Silver Bow trade permits
Trade permits are commonly required in addition to the building permit. Montana DLI and certified local building programs regulate electrical, plumbing, mechanical, fuel gas, elevator, boiler, fire, and specialty permits depending on location and scope.
Electrical permits
Butte-Silver Bow does not issue electrical permits; they come from the state Building Codes Program, which requires one for any electrical installation in new construction, remodelling or repair, including service upgrades, panels, new circuits, solar PV, EV chargers and generators. Electrical work follows the state-adopted NEC and state licensing rules; an owner may do electrical work on their own home.
Plumbing & gas permits
Butte-Silver Bow issues plumbing permits. A licensed plumber must pull one whenever new pipe is installed, drain, waste, vent and water lines included. A homeowner may do plumbing without a permit only on their primary residence with no intent to sell; rentals and investment properties must be plumbed by a licensed plumber.
Mechanical / HVAC permits
Butte-Silver Bow issues mechanical permits, and homeowners as well as contractors must pull one. Its checklists say replacing any mechanical system or ductwork needs a mechanical permit, including boilers, forced-air furnaces and wood or pellet stoves. Boiler work may also need a state boiler permit.
Fire, occupancy, and specialty permits
Commercial projects may require fire alarm, sprinkler, suppression, hood, hazardous-material, sign, demolition, right-of-way, grading, floodplain, septic, elevator, special inspection, deferred submittal, and certificate of occupancy approvals before final use.
Rather not deal with the building department?
Get a free quote →Credential check: Since January 1, 2026, Montana construction contractors must hold a Construction Contractor License from the Montana Department of Labor & Industry, which replaced the former registration program; contractors with employees, corporations and manager-managed LLCs need it. An independent contractor with no employees is exempt from that license but must hold an Independent Contractor Exemption Certificate (ICEC, a separate certificate, not a construction license) or workers’ compensation coverage, and electrical, plumbing, elevator, boiler, fire protection and other specialty work can require separate state or local credentials.
How to get a building permit in Butte-Silver Bow

Submit application & plans
Submit through the Butte-Silver Bow GovWell portal, or by email to permits@bsb.mt.gov as the checklists direct. Electrical permits are filed separately with the state Building Codes Program.

Butte-Silver Bow’s residential checklists list rebar inspections before any concrete is poured (footings, foundation walls, deck sonotubes and retaining walls 4 feet or taller), a structural framing inspection before rough-ins, plumbing and mechanical rough-ins including a gas-line pressure test, firewalls where they apply, plumbing and mechanical finals, and a final building inspection. No certificate of occupancy is issued without the required inspections, and a missed inspection can mean uncovering the work. Electrical work is inspected by the state.
