Sidney, 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 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).; Sidney is a Montana DLI-certified jurisdiction for Building (B), ALL project types, within CITY LIMITS ONLY; certified official on file with DLI: Kale Rasmussen, 480-9113 (city phone format as printed in the roster; the City of Sidney's own published number for the same official is 406.433.1122). Verified directly by fetching and text-extracting the DLI Building Codes Bureau's 'MONTANA CERTIFIED LOCAL GOVERNMENT PROGRAM' roster PDF (updated 04/22/2026): the roster carries TWO SEPARATE line items — 'Richland County | B | Kale Rasmussen | 480-9113 | County except Sidney' and 'Sidney | B | Kale Rasmussen | 480-9113 | City Limits'. This confirms Sidney's own certification is a DISTINCT, SEPARATE entry from Richland County's countywide program, not a subset or duplicate listing — the same certified official (Kale Rasmussen, who is also Richland County's building inspector per richland.org/building.html) administers both programs, but the County's own certification explicitly EXCLUDES Sidney ('County except Sidney'), and Sidney has its own independent 'City Limits' certification. Source: https://bsd.dli.mt.gov/_docs/building-codes-permits/certified-city.pdf; Unlike several Montana B-only-certified cities (e.g., Hardin, Anaconda-Deer Lodge, Colstrip) whose certification is explicitly 'B (residential only)', Sidney's DLI roster entry lists plainly 'B' with no residential-only qualifier — matching the pattern of Choteau/Conrad/Cutbank/Glasgow/Lewistown/Red Lodge, i.e. Sidney's local Building certification covers BOTH residential and commercial building permitting within city limits. Corroborated directly by the City's own published forms: cityofsidneymt.com/fire-building/page/building-permit-applications lists both a 'Residential Building Permit Application' and a two-part 'Commercial Building Permit Application' as separate City-issued forms, each captioned 'WITHIN THE CITY LIMITS OF THE CITY OF SIDNEY.' Source: DLI roster PDF; https://cityofsidneymt.com/fire-building/page/building-permit-applications; Electrical and Mechanical/HVAC permitting are NOT locally certified in Sidney — the DLI roster's Sidney line lists only 'B' (no 'E' or 'M' code), meaning Electrical and Mechanical permits of any project type within Sidney city limits route DIRECTLY to the Montana DLI Building Codes Bureau for state administration, exactly as in a non-certified jurisdiction. Plumbing is likewise not covered by Sidney's own DLI code letter, and is independently confirmed as state-administered by the City's own Residential and Commercial Building Permit Application forms, both of which include a checklist item 'State Plumber Permit (required)' and 'State Electrical Permit (required)' under the Contractor section — direct documentary evidence, from the City's own application forms, that plumbing and electrical permits for construction within Sidney are STATE permits, not city-issued.
