exempting certain dwelling units from automatic sprinkler system requirements.

HB 1004 exempts detached residential buildings with up to four dwelling units (such as single-family homes, duplexes, triplexes, and fourplexes) from automatic sprinkler system requirements in new construction, renovations, or conversions. The bill amends state building and fire codes to remove the mandate for sprinklers in these properties while allowing local authorities to require alternative water sources like cisterns or dry hydrants. Existing buildings without sprinklers are not required to retrofit them, and the exemption applies to all new projects starting 60 days after the bill's passage.
