Arlington FAQ
Are existing buildings forced to retrofit sprinklers?
Generally no, unless a major change of use, large addition, or substantial remodel triggers full code compliance under the adopted International Existing Building Code.
Do single-family homes need sprinklers?
Most do not, but very large homes or those with restricted fire-department access may require NFPA 13D residential sprinkler systems under local amendments.
Fort Worth FAQ
Are sprinklers required in new Fort Worth single-family homes?
Generally no. Texas Local Government Code allows cities to opt out of the IRC R313.2 residential sprinkler mandate for detached homes, and Fort Worth has not adopted a citywide requirement for new single-family construction.
Do sprinklers need annual inspections in Fort Worth?
Yes. NFPA 25 and Texas State Fire Marshal rules require annual inspection, testing, and tagging by a licensed sprinkler contractor. Fort Worth Fire Marshal staff verify tags during periodic occupancy and complaint inspections.
