Summary
Yuma does not require automatic fire sprinklers in new one- and two-family homes. The city's 2024 IRC amendments strike the sprinkler mandate entirely, citing state preemption under A.R.S. § 9-807, so builders of single-family and duplex dwellings need not install residential sprinkler systems to get a permit.
(GG) Section R309.2 One- and two-family dwelling automatic fire sprinkler systems. Delete section in its entirety. (Preemption by ARS § 9-807).
(HH) Section R309.2.1 Design and installation. Clarification: This section is to remain.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: 2026 S-74: Current through May 20, 2026).
Full Breakdown
2 along with it. § 9-807, the state law that bars cities from mandating residential fire sprinklers in one- and two-family dwellings without a qualifying local finding. The deletion sits among dozens of other lettered amendments to the 2024 IRC in § 150-181, running from foundation and seismic bracing rules to mobile-home setback exceptions, all administered by the Yuma Building Safety Division under the same subchapter. 1 still govern how it must be engineered, even though nothing in the adopted code compels the system in the first place.
Practically, this means a single-family home or duplex permitted in Yuma today needs no sprinkler system to pass plan review or final inspection under the IRC track; commercial and multi-family constructions permitted under the separate International Building Code are unaffected and follow whatever sprinkler thresholds that code sets.
Violations & Fines
There is no sprinkler-specific violation or fine here because there is no local mandate to violate: § 150-181(GG) removes the requirement rather than creating one. A permit applicant cannot be cited by Yuma Building Safety for omitting residential fire sprinklers in a one- or two-family dwelling. Standard IRC and City Code enforcement for other building elements, including any sprinkler system a builder chooses to install, still runs through the Building Safety Division's normal plan review, inspection and correction-notice process under Chapter 150.
