Fire Sprinkler Requirements
Casper's adopted 2024 International Residential Code strips out the model fire sprinkler rules entirely. City Code Section 15.02.120 deletes IRC Section R317.5, Fire Sprinklers, and Section 15.02.130 deletes IRC Section R309, Automatic Fire Sprinkler Systems, both in full. New one- and two-family homes built in the City of Casper are not required to install residential fire sprinkler systems under either provision.
