Full Breakdown

Aurora adopted the 2021 International Residential Code as its residential building code, but Sec. 22-191 of the City Code deletes IRC Sections R313 and P2904, the automatic residential fire sprinkler provisions, in their entirety. R313 is the IRC's mandate for sprinklers in new one- and two-family dwellings and townhouses; P2904 is the companion plumbing chapter for dwelling-unit sprinkler systems. By striking both, Aurora opted out of the statewide-model sprinkler mandate: new single-family homes, duplexes, and townhouses built under the city's residential code do not need a fire sprinkler system to get a certificate of occupancy. Commercial and multifamily construction is reviewed under separate fire and building code chapters not addressed here.

Violations & Fines

Not applicable: no sprinkler installation is required, so there is no sprinkler-omission violation for covered residential construction.

Frequently Asked Questions

Does Aurora require sprinklers in new houses?
No. Sec. 22-191 deletes IRC §§ R313 and P2904 entirely, so the automatic residential fire sprinkler mandate does not apply in Aurora.
Does this apply to apartments or commercial buildings?
No: this deletion is in the residential (IRC) code for one- and two-family dwellings and townhouses; multifamily and commercial buildings fall under separate fire/building code provisions.
