Ames, IA Building Safety: Fire Sprinkler Requirements (2026)

Ames Municipal Code Sec. 5.208(31) amends Section 612, Residential Fire Sprinkler Systems, of the adopted plumbing code by deleting sections 612.0 through 612.7.2 outright, so the city imposes no residential fire-sprinkler mandate on one- and two-family dwellings. A separate and older mandate targets larger existing buildings: Sec. 8.301, Existing Buildings to Have Sprinkler Systems, required retrofitting an automatic sprinkler system, installed to Section 403.2 of the 2003 International Building Code and Section 903 of the 2003 International Fire Code, in three building types: existing high-rises with occupied floors more than 75 feet above the lowest fire department vehicle access, institutions housing more than 16 people on a 24-hour supervised basis such as hospitals, nursing homes and assisted living facilities, and dormitories, fraternity and sorority houses or barracks sleeping more than 16 unrelated people.

The retrofit deadline was October 1, 2011, but owners unable to meet it could seek up to two extensions from the Building Board of Appeals, the first sought before October 1, 2010 for a three-year extension to 2014, and a second sought before October 1, 2013 for a further two-year extension to 2016, each conditioned on financial need, documented unsuccessful funding efforts and a completed compliance plan. Sec. 8.501 gives the Building Board of Appeals continuing jurisdiction over sprinkler-extension requests. A Chapter 8 violation, including a missed retrofit deadline, is a municipal infraction under Sec. 8.601.
