Mechanical / HVAC Permit (State-Issued) in Richland County (Unincorporated Areas and Towns, excluding Sidney), Montana

Because Richland County holds no DLI certification in Mechanical, mechanical/HVAC work anywhere within unincorporated Richland County and its non-Sidney towns requires a Mechanical Permit issued directly by the Montana DLI Building Codes Bureau in Helena, not by the county, under the 2021 International Mechanical Code and International Fuel Gas Code.

Richland County (Unincorporated Areas and Towns, excluding 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 roster (bsd.dli.mt.gov/building-codes-permits).; Richland County is a Montana DLI-certified jurisdiction for BUILDING (B) ONLY — verified directly against the DLI Building Codes Bureau's own 'Montana Certified Local Government Program' roster PDF (updated 04/22/2026, fetched directly and text-extracted via pdftotext): 'Richland County | B | Kale Rasmussen | 480-9113 | County except Sidney'. Unlike several other Montana counties in this dataset (e.g. Deer Lodge/Anaconda-Deer Lodge, Hardin/Big Horn County), Richland County's Building certification is NOT flagged 'residential only' or 'commercial only' on the roster — it applies to Building generally, county-wide, EXCEPT within Sidney.; The SAME roster line item lists Sidney separately and distinctly: 'Sidney | B | Kale Rasmussen | 480-9113 | City Limits'. Sidney's certification is scoped to 'City Limits' while Richland County's is explicitly scoped 'County except Sidney' — these are two separate certified-jurisdiction entries sharing the same certified Building Inspector (Kale Rasmussen), but with mutually exclusive geographic scope. Sidney's own permitting program is documented in a companion jurisdiction file (sidney.json) and is OUT OF SCOPE for this file.; No other town within Richland County (Fairview, Lambert, Savage) appears as its own separate line on the DLI roster. Since the roster explicitly carves out only Sidney from Richland County's 'County' jurisdiction line, Fairview, Lambert, and Savage are therefore covered BY Richland County's own Building certification, not separately certified and not state-enforced for Building. Source: Montana DLI Building Codes Bureau, Certified City, County and Town Programs roster PDF (updated 04/22/2026), https://bsd.dli.mt.gov/_docs/building-codes-permits/certified-city.pdf; Electrical, Plumbing, and Mechanical/HVAC permitting and inspection anywhere in Richland County (outside Sidney) are NOT locally certified — these remain under DIRECT STATE ENFORCEMENT by the Montana Department of Labor & Industry, Building Codes Bureau. This is explicitly confirmed on the Richland County General Q&A webpage: 'There are several different types of permits based on the type of construction - structural, plumbing, mechanical, and electrical. Most home owner projects require more than 1 type of permit. Richland County can provide building permits but the others are provided by Montana.' Source: https://www.richland.org/general-qa.html; Statutory basis for the certified-local-government model: 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 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), applicable as the substantive code baseline for both Richland County's own locally-certified Building program and the state-enforced trades: 2021 International Building Code (IBC), 2021 International Residential Code (IRC), 2021 International Existing Building Code (IEBC), 2021 International Energy Conservation Code (IECC), ICC A117.1 Accessibility (2017 Edition), 2021 Uniform Plumbing Code (UPC — state-enforced here), 2021 International Mechanical Code (IMC — state-enforced here), 2021 International Fuel Gas Code (IFGC — state-enforced here), 2020 National Electrical Code (NEC — state-enforced here), 2021 International Swimming Pool and Spa Code (ISPSC), Wildland Urban Interface Code, all effective June 11, 2022 statewide. Source: https://bsd.dli.mt.gov/building-codes-permits/current-codes; Richland County's OWN 'Building Codes' webpage (richland.org/building-codes.html) is, on direct review, stale/outdated: it lists the county's LOCAL adoption as the 2012-edition International Codes (2012 IBC/IEBC/IECC/IRC) and separately lists a mix of older statewide effective dates (including a November 6, 2014 baseline, 2014 NEC, and a 2015-edition ISPSC effective January 8, 2016) rather than the CURRENT 2021-edition/June 11, 2022 statewide baseline confirmed directly on the DLI Building Codes Bureau's own Current Codes page. This is reported as an honest discrepancy between the county's own (apparently unmaintained) codes page and the state's authoritative current-codes page, not resolved by invention — the DLI's Current Codes page is treated as the governing, up-to-date source for code editions actually enforced today. Source: https://www.richland.org/building-codes.html (webFetch, 2026-07-04) vs. https://bsd.dli.mt.gov/building-codes-permits/current-codes. Local amendments apply — see the Richland County (Unincorporated Areas and Towns, excluding Sidney) overview page for the full list.

The Montana Department of Labor & Industry Building Codes Bureau, not the county — Richland County holds no Mechanical certification. Fees are calculated from project value starting at $48 for the first $1,000 plus $14 per additional $1,000 up to $10,000.
