Cascade County Building and Safety Divisions
In unincorporated Cascade County, Montana, building code enforcement is handled by the Montana Department of Labor and Industry (DLI) Building Codes Program. The Cascade County Planning and GIS Department is responsible for administering zoning regulations, floodplain permits, and subdivision reviews. For building code work that is not exempt, you must apply separately through the Montana DLI portal or by mail. Plumbing work must comply with the Montana Plumbing Code, which is based on the Uniform Plumbing Code (UPC). A plumbing permit is generally required for new water supply installations and for alterations that extend, reroute, or replace supply lines. This permit is issued through local building departments or, in unincorporated areas, through DLI's state plumbing program. Licensed installation is required, with work performed or supervised by a licensed journeyman or master plumber.
Rules for Properties in Unincorporated Areas
For properties in unincorporated areas of Cascade County, a two-layer permit system is in place. First, a Location/Conformance Permit (zoning permit) is required from the Cascade County Planning and GIS Department for all proposed buildings, structures, signs, land uses, and changes in land use within the Zoning Jurisdictional Area, unless exempted. Second, for commercial or non-exempt building code work, a separate state DLI building permit is necessary. This includes plumbing work. The Montana DLI Building Codes Program handles building code enforcement for these areas. Exemptions from building permits in unincorporated Cascade County generally include non-commercial structures of 200 square feet or less.
