Colorado Springs, CO Building Safety: Fire Sprinkler Requirements (2026)

J, titled 'Lots Requiring Smoke Alarms or Sprinklers,' addresses lots where fire apparatus response is slower because of distance or terrain. It requires either a monitored smoke alarm system or a sprinkler system for all new homes built on lots whose lot lines sit more than 600 feet from the entrance of a cul-de-sac, or on lots where the only vehicle access is a road graded steeper than 10 percent. The City built in two grandfather dates: the rule does not apply to subdivision plats recorded before March 24, 1981, or to subdivisions where a Development Plan was approved before April 1, 1993, so older established neighborhoods on remote cul-de-sacs are not retroactively required to retrofit.

Every lot that meets either the distance or the grade trigger must be identified on the recorded Subdivision Plat, giving future builders and buyers notice at the platting stage rather than at building-permit issuance. 604B requires those lots to separately comply with the City's Fire Prevention Code and Standards, so a remote WUI-O lot can face both the smoke-alarm-or-sprinkler trigger and the WUI-O fuels-management and construction requirements at once. The provision was adopted by Ordinance 23-03 as part of the Design Standards article of the Subdivision chapter of the Unified Development Code.
