Summary
In the City of Bloomington, one- and two-family homes are not required to install automatic fire sprinklers: the city deleted the IRC's mandatory sprinkler sections entirely. Instead, Bloomington City Code § 10-501 forces every builder to formally offer the buyer the option before a permit issues.
SEC. R313.1 TOWNHOUSE AUTOMATIC FIRE SPRINKLER SYSTEMS. Modify by deleting the section in its entirety. SEC. ... R313. ... 2 ONE- AND TWO-FAMILY DWELLINGS AUTOMATIC FIRE SYSTEMS. Modify by deleting the section in its entirety. SEC. R313.2.1 DESIGN AND INSTALLATION. Modify the language to read as follows: When provided, automatic residential fire sprinkler systems shall be designed and installed in accordance with Section P2904 or NFPA 13D/2010. SEC. R313.3 AUTOMATIC FIRE SPRINKLER SYSTEMS; MANDATORY OFFER REQUIRED. A contractor or builder of a one- or two-family dwelling subject to the International Residential Code shall: (a) Offer to the prospective purchaser or buyer the option to install, at the buyer's expense, an automatic fire sprinkler system ... (c) Before issuance of a building permit for any one- or two-family residence, the contractor/applicant shall provide to the Economic & Community Development Department a document signed by both the contractor and prospective purchaser or buyer ... stating that the contractor has provided to the prospective purchaser or buyer the information required by Section 1(b) of this ordinance.
Full Breakdown
Article V of Chapter 10 amends the 2018 International Residential Code, and it strikes the mandatory sprinkler mandate at its source: Sec. 1 (townhouse automatic fire sprinkler systems) and Sec. 2 (one- and two-family dwelling automatic fire systems) are each deleted in their entirety, so Bloomington imposes no blanket requirement to install sprinklers in new houses or townhouses. Where a builder or buyer does choose to install one voluntarily, Sec. 1 still controls the engineering: the system must be designed and installed to Section P2904 or NFPA 13D/2010.
In place of a mandate, Sec. 3 requires a mandatory offer: before the Economic & Community Development Department will issue a building permit for a one- or two-family residence, the contractor or builder must offer the prospective buyer the option to install a sprinkler system at the buyer's own expense, provide Home Fire Sprinkler Coalition literature explaining the costs and benefits, and file a signed document confirming that offer was made. For spec homes built before a buyer is identified, the contractor signs in the buyer's place.
The signed offer form itself is written into the code, including a line disclosing that homes without a sprinkler system have floors protected under a different code standard instead.
Violations & Fines
A builder cannot obtain a building permit for a one- or two-family residence under Sec. R313.3 without first filing the signed mandatory-offer document with the Economic & Community Development Department; withholding the offer or the signed form blocks permit issuance rather than triggering a separate fine.
