Summary
Peoria doesn't require automatic fire sprinklers in new one- and two-family homes or townhouses. When the city adopted the 2018 International Residential Code amendments in Sec. 5-124, it explicitly deleted Section R313.1 (townhouse sprinkler systems) and Section R313.2 (one- and two-family dwelling sprinkler systems) in their entirety, opting the city out of the model code's residential sprinkler mandate.
Section R313.1 shall be deleted in its entirety.
Section R313.2 shall be deleted in its entirety.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Code of Ordinances: Supplement 119).
Full Breakdown
Sec. 5-123 adopts the 2018 edition of the International Residential Code for One- and Two-Family Dwellings, and Sec. 5-124 amends that adopted code section by section. 2 shall each be deleted in their entirety. 2 for one- and two-family dwellings, so builders of new single-family homes, duplexes and townhouses in Peoria are not required to install residential fire sprinklers as a condition of the building permit issued under Sec. 5-91. Sprinklers still come into play elsewhere in the code: Sec. 2. Commercial and multi-family construction permitted under the separately adopted International Building Code, and any fire-suppression system installed voluntarily or by requirement, must still be registered and have inspection and test reports filed through The Compliance Engine, the city's web-based reporting service, under the International Fire Code amendments in Sec. 11-92(k).
Violations & Fines
There's no sprinkler-installation offense for ordinary new residential construction, since Peoria opted out of R313.1 and R313.2. Where a sprinkler system is required elsewhere, such as an existing building's occupancy-change trigger under Sec. 5-131 or a commercial building under the adopted International Building Code, skipping it is enforced as a Sec. 5-127 chapter violation, fined $500.00 to $2,500.00, and a service provider that fails to file required sprinkler inspection reports through The Compliance Engine faces a separate minimum $250.00 fine per report under Sec. 11-92(k).
