Austin FAQ
Do I have to add sprinklers to my existing Austin home?
No. The mandate covers new construction only. Existing single-family homes are not required to retrofit unless major additions or substantial alterations trigger code-compliance thresholds in Austin Building Criteria Manual.
Did Texas try to ban Austin's sprinkler rule?
Texas Health and Safety Code 1301.5515 normally lets cities opt out, not in. Austin's choice to enforce R313 is voluntary uphill regulation. Builders and lobbyists have pushed legislative repeal but it remains in effect.
Pflugerville FAQ
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.
