Summary

Springfield adopted the 2012 International Residential Code but struck the code's automatic fire sprinkler mandates. Sec. 170.10.03(e) deletes IRC Sections R313.1 and R313.2, so the city does not require sprinkler systems in new townhouses or one- and two-family dwellings, unlike jurisdictions that keep the full IRC intact.

(e)The following are deleted from the International Residential Code: Section R105.2 Work exempt from permit Section R112 Board of Appeals Section R313.1 Townhouse automatic fire sprinkler systems Section R313.2 One- and two-family dwellings automatic fire (sprinkler) systems Section R501.3 Fire protection of floors Chapter 11 Energy Efficiency

Full Breakdown

Sec. 2, Section R112, and Chapter 11 (energy efficiency). Practically, that means a new single-family home, duplex, or townhouse built in Springfield is not required by the city building code to install residential sprinklers, even though the base 2012 IRC model code would otherwise mandate them. 03(b)) are instead governed by the adopted 2012 IBC and the NFPA 101 Life Safety Code (2000 edition), which carry their own fire-suppression triggers based on occupancy classification and size. 03(b), can still trigger IBC or NFPA 101 sprinkler requirements even though the IRC's one- and two-family mandate was struck.

Violations & Fines

Because Springfield deleted the IRC sprinkler mandate, there's no local citation for skipping sprinklers in a one- or two-family home or townhouse. A builder who installs a sprinkler system anyway must still meet plumbing and fire code standards for the equipment installed; violations instead arise if construction proceeds without the required building permit or fails an inspection under Sec. 170.10.06(a).

Frequently Asked Questions

Does Springfield require fire sprinklers in new houses?
No. Sec. 170.10.03(e) deletes IRC Sections R313.1 and R313.2 from the adopted 2012 International Residential Code, so one- and two-family homes and townhouses built in the city are not locally required to have automatic fire sprinkler systems.
What about apartment buildings or condos?
Buildings with three or more units fall outside the deleted IRC sections and are instead regulated under the adopted 2012 International Building Code and the NFPA 101 Life Safety Code (2000 edition), which set their own fire-suppression requirements depending on occupancy classification and size.
Can I still install sprinklers voluntarily?
Yes. Deleting the IRC mandate only removes the requirement; homeowners and builders may still install residential sprinkler systems, which must be permitted and inspected like any other plumbing or fire-protection work under chapter 170's general permit and inspection provisions.
