Residential building permit feeNo fixed valuation-based fee table was found published on hardinmt.com, hardinmontana.info, or in the City's downloadable Building Permit Application form (which has a blank 'PROJECT VALUATION' field but no printed fee schedule) as of this review — an honest publication gap after direct review of the City's own permit materials, not an inferred or invented figure.

Inspection process

    Tips

    • Hardin's local Building certification covers RESIDENTIAL construction only — a commercial project of any kind (new construction, addition, alteration) does not qualify for city-issued permitting and must go to the state DLI Building Codes Bureau instead; see the commercial-building-permit-state entry.
    • The City's own Building Permit Application form is a reformatted version of the state's BCP-1 template and still shows Helena mailing instructions in places — when applying for a RESIDENTIAL permit in Hardin, submit to the City (406 N. Cheyenne Ave or the Citizen Portal), not to Helena; the state mailing address on the form applies to non-covered (commercial, trade) work.
    • Electronic plan submittal is explicitly preferred per the City's application form.
    • Contact Joe Connelly or Nathan McConnell at (406) 665-9260 Ext. 106 (or jconnelly@hardinmt.com / nmcconnell@hardinmt.com) with any questions before applying.
    • No published fee schedule exists online; get a written quote from the Building Department before budgeting a project.

    Hardin, 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, where a city's Building certification is itself partial (e.g. residential-only), non-certified project types — 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).; Hardin is a Montana DLI-certified jurisdiction for Building (B), RESIDENTIAL ONLY, within city limits; certified official on file with DLI: Joseph Connolly (listed on City of Hardin's own site as 'Joe Connelly'), (406) 665-9264. Verified directly against the DLI Building Codes Bureau's 'Montana Certified Local Government Program' roster PDF, updated 04/22/2026 (fetched and text-extracted directly from the source PDF): 'Hardin | B (residential only) | Joseph Connolly | 665-9264 | City Limits'. This is a NARROWER certification than the B-only-but-all-project-types pattern seen in Choteau/Conrad/Cut Bank/Glasgow/Lewistown/Red Lodge — Hardin's own certification does not cover COMMERCIAL building work at all, meaning commercial building permits in Hardin route to the state DLI Building Codes Bureau exactly as they would in a non-certified jurisdiction, in addition to Electrical/Plumbing/Mechanical for all project types. Source: https://bsd.dli.mt.gov/_docs/building-codes-permits/certified-city.pdf; Hardin, MT Code of Ordinances, Title 4 Building Regulations, Chapter 1 Building Codes (current through Ord. 2025-04, passed 12-4-2025) contains three sections: 4-1-1 Adoption Of Codes And Regulations, 4-1-2 Building Code Adopted, and 4-1-3 Other Codes Enforced By State Officials — a notably thin chapter (no locally-authored fee schedule or plan-review-timeline section), consistent with a small, partially-certified jurisdiction that enforces state-adopted code editions rather than authoring independent code text or a distinct administrative process. Section 4-1-3's title ('Other Codes Enforced By State Officials') is itself corroborating evidence of the residential-only/state-routed-commercial split described by the DLI roster. Source: https://codelibrary.amlegal.com/codes/hardinmt/latest/hardin_mt/0-0-0-994; Per the Montana DLI Building Codes Bureau's Current Codes page (statewide effective date June 11, 2022, applicable uniformly to all certified and state-enforced jurisdictions): 2021 IBC, 2021 IRC, 2021 IEBC, 2021 IMC, 2021 IFGC, 2021 IECC, 2021 ISPSC, 2021 UPC, 2020 NEC, 2017 ICC A117.1 Accessibility. Hardin's own Building Permit Application form cites Title 50, Chapter 60, Section 104, MCA and ARM 24.301.131 (the same statutory/administrative basis as the state's own BCP-1 form), consistent with a residential-certified jurisdiction enforcing the state-adopted editions without independently amended local code text.
