Troy, Montana has adopted: Montana has a mandatory statewide building code administered by the Montana Department of Labor & Industry (DLI) Building Codes Bureau, amended by the Administrative Rules of Montana (ARM) Title 24, Chapter 301. Cities, counties, and towns may become 'certified' to locally administer permitting and inspection for all or part of the code; non-certified trades and non-certified project scopes in a partially-certified jurisdiction fall under direct state administration by the DLI Building Codes Bureau. Source: Montana DLI Building Codes Bureau, Certified City, County and Town Programs (bsd.dli.mt.gov/building-codes-permits).; Troy is a Montana DLI-certified jurisdiction for Building (B), RESIDENTIAL ONLY, plus Swimming Pool (SP), within city limits; certified official on file with DLI: David Jones, (406) 295-9851. Verified directly against the DLI Building Codes Bureau's 'Montana Certified Local Government Program' roster PDF (fetched via browser-header curl and read directly with pdftotext, not taken on secondhand summary): 'Troy | B (residential only), SP | David Jones | 295-9851 | City Limits'. This means COMMERCIAL building permits within Troy city limits, and Electrical/Plumbing/Mechanical permits for ALL project types (residential and commercial), are issued DIRECTLY by the Montana DLI Building Codes Bureau, not the City. Source: https://bsd.dli.mt.gov/_docs/building-codes-permits/certified-city.pdf; The City of Troy's own 'Building Permit Requirements' packet (dated February 7, 2023, filename Building Permit Application 2022.docx/pdf) references the '2009 IBC-IRC' on its Inspection Record card ('REMEMBER 2009 IBC-IRC required the permit holder to notify the building official when work is ready for inspection') — the City's packet has not been refreshed to reference the current 2021-edition code, even though the statewide code in force is now the 2021 edition. This is reported as an observed inconsistency in the City's own published document, not an invented fact — directly parallel to the same inconsistency found in Libby's packet.; Per the Montana DLI Building Codes Bureau's Current Codes page (statewide effective date June 11, 2022, applicable to all certified and state-enforced jurisdictions alike): 2021 IBC, 2021 IRC, 2021 IEBC, 2021 IMC, 2021 IFGC, 2021 IECC, 2021 ISPSC, 2021 UPC, 2020 NEC, 2017 ICC A117.1 Accessibility. Source: bsd.dli.mt.gov/building-codes-permits/current-codes; Troy's own Building Permit Requirements packet does not separately name IECC, IEBC, or ISPSC edition years the way Libby's City page does — the City's packet references only the general 'City, State, and National regulations' framing and the 2009 IBC-IRC inspection-card citation noted above. No additional code-edition citations were found on the City's own materials beyond what is reported here; omitted rather than inferred.. Local amendments apply — see the Troy overview page for the full list.
