HB 2341 Arizona House · 57th Legislature - First Regular Session

fire protection systems; inspections.

HB 2341 establishes standards for inspecting fire dampers and smoke dampers in buildings, requiring inspections to follow nationally recognized standards adopted by local governments. It limits county adoption of building and fire codes to specific types (e.g., nationally recognized codes for construction or fire prevention) and prohibits counties from mandating fire sprinklers in single-family homes or small residential buildings (up to two units), except for pre-2009 codes. The bill also explicitly prevents counties from requiring sprinklers for accessory structures like garages or sheds, protecting property owners’ rights to choose sprinkler installation. These provisions override conflicting local regulations and ensure fire safety standards align with state guidelines without imposing new requirements on residential properties.
