Full Breakdown
Arlington has adopted the International Building Code and International Fire Code through Chapter 10 of the City Code, with local amendments addressing sprinkler thresholds.

Single-family homes above defined floor-area thresholds or with limited fire-department access may also require NFPA 13D residential sprinklers. The Arlington Fire Department Fire Marshals Office reviews plans, witnesses acceptance tests, and inspects systems during annual occupancy walkthroughs to verify maintenance certifications remain current.
Violations & Fines
Operating a building without a required sprinkler system is a fire code violation with fines up to 2,000 dollars per day and possible certificate-of-occupancy revocation by the city.
