A bill for an act relating to fire protection sprinkler systems in certain residential properties.

SF 310 prohibits requiring fire sprinkler systems in small attached residential buildings. It specifically bans mandatory sprinkler installation for "series of attached single-family residences" with fewer than seven units. The bill mandates that Iowa's state building code commissioner adopt this prohibition and prevents local governments from imposing such requirements. This directly affects developers and builders constructing small attached housing projects, removing a current requirement for sprinkler systems in those properties.
