Codes adopted

Montana adopts a single statewide building code by rule and, by default, enforces it directly — local governments only gain enforcement authority once the state certifies them. Under the Montana Building Codes Act (Mont. Code Ann. Title 50, Chapter 60), the Department of Labor & Industry's Building Codes Bureau adopts one state building code applicable everywhere (§ 50-60-203, codified further at Administrative Rules of Montana Title 24, Chapter 301) — currently the 2021 editions of the IBC, IRC, IMC, IFGC, IECC, IEBC, ISPSC, and UPC, with the 2020 NEC for electrical (effective statewide since 6/11/2022 per the Bureau's own Current Codes page). A city, county, or town may adopt and enforce its own building-code program under § 50-60-301, but its adopted code "may include only codes adopted by the Building Codes Bureau" — a local edition can never diverge from or be less stringent than the state's. Critically, under § 50-60-302, a local government cannot enforce ANY building code — even one it has formally adopted — until the Bureau certifies its program (requiring an approved code, a published fee schedule, an enforcement plan, and properly licensed or nationally certified inspectors); certification is granted per TRADE, not as one blanket designation. The Bureau's own "Certified City, County and Town Programs" list uses the key B=Building, P=Plumbing, E=Electrical, M=Mechanical, SP=Pool, W=Wildland-Urban-Interface — a jurisdiction can be certified for Building only while Electrical/Plumbing/Mechanical remain directly state-enforced within the same city limits (e.g., Havre, Anaconda-Deer Lodge), or certified across all trades (e.g., Billings, Missoula, Great Falls, Bozeman, Helena, Kalispell). Non-certified jurisdictions — most of Montana's unincorporated county land, since very few counties appear on the certified list — fall under direct enforcement by the state Building Codes Bureau (§ 50-60-304). Montana also exempts private homes and buildings of four or fewer dwelling units not serving transient guests from the state building-permit requirement entirely, though electrical, plumbing, and mechanical permits remain separately required regardless. Always confirm with the specific jurisdiction which trades it is certified for versus which remain directly state-enforced.

• City of Deer Lodge is a MONTANA CERTIFIED LOCAL GOVERNMENT for BUILDING permitting only, RESIDENTIAL ONLY — per the Montana Building Codes Bureau's official 'Certified Local Government Building Code Jurisdictions' roster (updated 04/22/2026), entry: 'Deer Lodge (City) — B (residential only) — Sean Beach — 846-2238 — City Limits.' This is a SEPARATE line item on the same roster from 'Deer Lodge County — B (residential only) — Greg Bahr — 563-4010 — County' (the Anaconda-Deer Lodge consolidated government), confirming these are two distinct, independently-certified jurisdictions with different building officials.
• The City's own Residential Building Permit portal (iWorQ) states directly: 'All residential building permits are reviewed by the City of Deer Lodge,' while 'Mechanical, electrical, plumbing, and commercial building permits are reviewed by the State of Montana' — confirming the Building-only, residential-only certification scope in the city's own words, independent of the state roster.
• Statutory basis for the certified-local-government model: a city, county, or town may adopt a building code by ordinance and enforce it locally ONLY if certified by the Building Codes Program as complying with applicable statutes/rules (current adopted code, current fee list, and enforcement plan filed and approved) — per ARM Title 24, chapter 301, subchapter 2 (Local Jurisdiction Administrative Rules) and Title 50, chapter 60, MCA (Local Jurisdiction Statutes). Absent local certification for a given trade (electrical/plumbing/mechanical/commercial building here), the State Building Codes Bureau retains jurisdiction under Title 50, chapter 60, MCA.
• Statewide adopted codes (Administrative Rules of Montana, Title 24, chapter 301), verified directly against the Montana Building Codes Bureau's Current Codes page, apply as the substantive code baseline for both the locally-certified residential Building program and the state-enforced trades/commercial building: 2021 International Building Code (IBC), effective June 11, 2022
• 2021 International Residential Code (IRC), effective June 11, 2022
• 2021 International Existing Building Code (IEBC), effective June 11, 2022
• ICC A117.1 Accessibility, 2017 Edition, effective June 11, 2022
• 2021 Uniform Plumbing Code (UPC), effective June 11, 2022 — enforced directly by the State Building Codes Bureau in Deer Lodge (not locally certified)
• 2021 International Mechanical Code (IMC), effective June 11, 2022 — enforced directly by the State Building Codes Bureau in Deer Lodge (not locally certified)
• 2021 International Fuel Gas Code (IFGC), effective June 11, 2022 — enforced directly by the State Building Codes Bureau
• 2020 National Electrical Code (NEC), effective June 11, 2022 — enforced directly by the State Building Codes Bureau in Deer Lodge (not locally certified)
• 2021 International Energy Conservation Code (IECC), effective June 11, 2022
• 2021 International Swimming Pool and Spa Code (ISPSC), effective June 11, 2022
• 2021 Wildland Urban Interface Code, effective June 11, 2022

Permit types & fees

• Residential Building Permit (New Construction / Addition / Remodel)

  Required for new single-family residential construction, additions, remodels, and a wide range of specific residential scopes (fences, windows/doors, siding, decks, roofing, stairs/ramps, egress windows, demolition) within Deer Lodge city limits. Issued and reviewed LOCALLY by the City of Deer Lodge Building Inspector (Sean Beach) — Deer Lodge is a Montana-certified local government for Building permitting (residential only), per the state Building Codes Bureau's certified-jurisdiction roster. Reviewed against the 2021 IRC/IBC (Administrative Rules of Montana, Title 24, chapter 301). The city's own portal explicitly states mechanical, electrical, plumbing, and COMMERCIAL building permits are reviewed by the State of Montana, not the city.

  →

• Electrical Permit

  Required for electrical installations, alterations, service changes, and panel upgrades in the City of Deer Lodge. Electrical permitting is NOT locally certified in Deer Lodge — it is issued and inspected DIRECTLY by the Montana Department of Labor & Industry, Building Codes Bureau, under the 2020 National Electrical Code (NEC), effective June 11, 2022. Confirmed both by the state's certified-jurisdiction roster (Deer Lodge City listed with a 'B (residential only)' designation only, no 'E') and by the city's own permit portal description.

  →

• Plumbing Permit

  Required for plumbing installations, alterations, and repairs in the City of Deer Lodge. Plumbing is NOT locally certified in Deer Lodge — it is issued and inspected DIRECTLY by the Montana Department of Labor & Industry, Building Codes Bureau, under the 2021 Uniform Plumbing Code (UPC), effective June 11, 2022.

  →

• Mechanical / HVAC Permit

  Required for heating, ventilation, air conditioning, and fuel-gas installations in the City of Deer Lodge. Mechanical is NOT locally certified in Deer Lodge — it is issued and inspected DIRECTLY by the Montana Department of Labor & Industry, Building Codes Bureau, under the 2021 International Mechanical Code (IMC) and 2021 International Fuel Gas Code (IFGC), both effective June 11, 2022.

  →

• Demolition Permit

  Required for demolition of a structure within Deer Lodge city limits, priced on the city's own Building Permit Fee Schedule as a flat $20 fee alongside other common residential scopes. Issued locally by the City of Deer Lodge Building Inspector through the same iWorQ application portal used for other Building Permit scopes.

  →

• Solar PV / Alternative Energy Permit (State-Issued)

  Required for installation of grid-tied residential or commercial rooftop/ground-mounted solar photovoltaic systems in the City of Deer Lodge. Because Deer Lodge (City) is DLI-certified for Building (B) RESIDENTIAL ONLY and holds no Electrical certification, the electrical/interconnection portion of any solar PV installation is issued directly by the Montana DLI Building Codes Bureau in Helena as an Application for Alternative Energy Permit — the same statewide form used for solar, wind, and hydro systems, already cited as a document option on this file's electrical-permit entry — not by the City of Deer Lodge. The City's own permit portal confirms electrical permits generally are reviewed by the State, not the City. Roof-mounted racking/structural attachment on a RESIDENTIAL structure may separately require the City's own Residential Building Permit; commercial solar structural work falls to the state, since Deer Lodge's Building certification does not extend to commercial.

  →

• EV Charger / EVSE Permit (State-Issued Electrical Permit)

  Installation of a Level 2 (or higher) electric vehicle charging station in the City of Deer Lodge is billed and issued under the same State Electrical Permit already documented on this file's electrical-permit entry — the Montana DLI Building Codes Bureau's BCP-1 Application for Residential (or Commercial) Electrical Permit has NO distinct EV-charger/EVSE line item; the form's fee schedule is organized entirely by service amperage, circuit count, and change-of-service type. A residential EV charger circuit is billed under the generic 'Interior/Exterior Wire or Rewire' circuit-addition tiers (or a 'Residential Change of Service' fee if the panel/service is also being upgraded to support the charger), the same mechanism used for any other new residential circuit. Because Deer Lodge is not DLI-certified for electrical, this is issued directly by the state Bureau, not the City Building Inspector.

• Sign Permit (City Zoning Permit — On-Site Signage)

  The City of Deer Lodge has no standalone 'sign permit' form. On-site signs permitted as accessory uses in the city's business and industrial districts are one of three triggering conditions on the single City Zoning Permit application (form rev. 05/13/2024) — the same form used for occupant/use changes in those districts (see this file's change-of-use-permit entry). The form's own text states a Zoning Permit is required for 'all on-site signs permitted as accessory uses in all business and industrial districts,' and separately asks whether the property complies with on-site signage requirements, with a Signage Plan required 'as needed/requested' to demonstrate compliance.

  →

• Change of Use / Occupancy Permit (City Zoning Permit)

  The City of Deer Lodge does not maintain a separate 'change of use' or 'certificate of occupancy' permit. A change in activity, use, or occupancy of a business/industrial-district space is handled through the same Zoning Permit (form rev. 05/13/2024) used for signage (see this file's sign-permit entry), per the form's own stated triggers: (1) occupying a vacant business/industrial-district space without triggering a Building Permit or Conditional Use Permit, and (2) any change in activity or use at a property in the business or industrial districts — which the form states 'complements Business Licenses.' Where the change of use also involves construction, or the use requires conditional approval, it instead falls under a Building Permit (locally issued for residential scopes; state-issued for commercial, since Deer Lodge's own DLI certification is residential-only) or the city's separate Conditional Use Permit (already documented in this file's localAmendments) rather than the Zoning Permit.

• Fire Sprinkler / Fire Alarm Permit (No Standalone Product — Folded Into the Commercial Building Permit and State Electrical Permit)

  Neither the City of Deer Lodge nor the Montana DLI Building Codes Bureau publishes a standalone fire-sprinkler or fire-alarm permit for Deer Lodge. The state Bureau's own permit-applications index lists only seven permit types (Boiler, Building, Electrical, Elevator, Factory Built Building, Mechanical, Plumbing) — no Fire Suppression or Fire Alarm category. Where the adopted 2021 IBC (Chapter 9, Fire Protection and Life Safety Systems, already part of this file's codesAdopted) requires a fire sprinkler system, plan review happens as part of the applicable Building Permit: because Deer Lodge's own DLI certification is Building (residential only), any commercial building — where sprinkler requirements typically arise — is a STATE-issued Commercial Building Permit, not a city permit. Fire alarm system wiring/interconnection is billed and inspected under the ordinary State Electrical Permit (already documented on this file's electrical-permit entry), since Deer Lodge is not electrical-certified. The City of Deer Lodge Fire Department (Fire Chief Brant Pierson) performs fire-code-enforcement review as part of the city's own Zoning Permit process — the Zoning Permit form includes a dedicated 'Fire Chief Comments' field — but the Fire Department does not itself issue a separate sprinkler/alarm construction permit. Businesses/individuals that sell, install, or service fire protection systems in Montana must separately hold a Montana Fire Protection License from the DLI Business Standards Division, a contractor/technician licensure requirement distinct from any project permit.
