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.

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).

Frequently Asked Questions

Does Peoria require sprinklers in new single-family houses?
No. Sec. 5-124 deleted IRC Sections R313.1 and R313.2, the model code's townhouse and one- and two-family dwelling sprinkler mandates, in their entirety when the city adopted the 2018 Residential Code. A standard new house or townhouse permit doesn't need a fire sprinkler system.
Are there any Peoria buildings that still need residential-type sprinklers?
Yes. Sec. 5-131 requires a sprinkler system when an existing building changes occupancy classification to a use that triggers sprinklers under Chapter 9 of the International Building Code, though live/work conversions in historic buildings under 12,000 square feet can qualify for an exception.
If I install a sprinkler system voluntarily, does Peoria still regulate it?
Yes. Sec. 11-92(k) requires service providers who maintain, inspect or test fire sprinkler systems in the city to register and submit reports through The Compliance Engine, and a provider that fails to file faces a minimum $250.00 fine per missed report.
