Full Breakdown

Texas HB 1820 prohibits municipalities and counties from requiring fire sprinklers in new one-family or two-family dwellings. Despite that ban, voluntary residential systems are permitted. New apartment buildings, hotels, schools, and most commercial occupancies above the IBC threshold must install NFPA 13 or 13R systems. ESD fire marshals review sprinkler plans during permitting. Existing commercial buildings undergoing major remodel may trigger retroactive sprinkler requirements. Lake Travis-area developments often install voluntary residential systems due to wildfire and remote-response concerns.

Violations & Fines

Stop-work orders, certificate-of-occupancy denial, civil penalties under Travis County Chapter 64, and insurance underwriting issues for nonconforming commercial structures.

Frequently Asked Questions

Must my new house have sprinklers?
No. State law prevents Travis County from mandating sprinklers in detached one-family or two-family homes, though voluntary installation remains allowed and insurance-friendly.
What about a duplex or fourplex?
Duplexes are exempt. Triplexes and larger fall under IBC multifamily provisions, generally requiring NFPA 13R sprinklers reviewed during the building permit process.
