Libby requires a sign permit for: In the Residential Business District (Libby Municipal Code 17.20.030): signs must not materially alter the appearance of the lot/dwelling; no electronic signs; illuminated signs must be downward-directional; real-estate/lease signs limited to 8 sq ft total; signs bearing an occupant's name/occupation limited to 6 sq ft per family housed; institutional (e.g., church) signs limited to 12 sq ft; non-illuminated political/campaign signs are allowed but must be removed within 3 days after the election; Downtown Business District (17.24.140) and Highway Commercial District (17.25.100) -- Libby's two zoning districts covering its actual commercial corridors -- each list a 'Signs' section that is currently published as 'Reserved,' meaning no adopted district-specific sign standard, application, or fee currently exists in the ordinance text for these commercial districts; A sign requiring structural anchoring or engineering review on a commercial building must be reviewed under the same 2021 IBC-based Commercial Building Permit issued directly by the Montana DLI Building Codes Bureau, since Libby's own DLI certification does not extend to commercial structures; An illuminated or electrically connected sign, residential or commercial, requires a separate state Electrical Permit from the DLI Building Codes Bureau, since Libby holds no DLI Electrical certification; No Montana sign-contractor-specific license was found; general contractor and/or electrical-contractor licensing requirements apply based on the trade performed.

Libby, 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).; Libby is a Montana DLI-certified jurisdiction for Building (B), RESIDENTIAL ONLY, plus Swimming Pool (SP), within city limits; certified official on file with DLI: Walter Snyder, (406) 293-2731. Verified directly against the DLI Building Codes Bureau's 'Montana Certified Local Government Program' roster PDF, updated 04/22/2026 (fetched and read directly, not taken on secondhand summary): 'Libby | B (residential only), SP | Walter Snyder | 293-2731 | City Limits'.

Local amendments apply — see the Libby overview page for the full list.

Libby's zoning ordinance (Title 17) does not currently have adopted sign standards for its two primary commercial zoning districts -- Downtown Business District and Highway Commercial District -- both districts' 'Signs' sections (17.24.140 and 17.25.100) are published as Reserved with no content, per the Jan 8, 2026 Municode version. The Residential Business District (17.20.030) does have adopted sign size/type limits. A structural or electrical sign component is instead permitted through the same channel as other building/electrical work -- the state DLI Building Codes Bureau -- since Libby's own certification doesn't cover commercial buildings or electrical work.

The Montana DLI Building Codes Bureau in Helena, under the 2021 IBC, since Libby's own DLI Building certification is residential-only and does not extend to commercial structures including commercial signage.
