Summary

Greeley does not require automatic fire sprinklers in one- and two-family homes: Sec. 22-95 deletes the IRC's sprinkler mandate outright, and Sec. 22-465 excepts them from the fire code's Group R rule.

903.2.8 Group R. An automatic sprinkler system installed in accordance with section 903.3 shall be provided throughout all buildings with a Group R fire area. Exception: One- and two-family dwelling units unless otherwise required based upon fire flow, fire apparatus access, to include gated communities, or other life safety hazard as deemed by the fire code official.

Full Breakdown

The 2021 IRC's automatic fire sprinkler mandate for one- and two-family dwellings (R313.2) is deleted in its entirety by Sec. 22-95. Greeley never adopted it. The fire code's parallel Group R sprinkler requirement (section 903.2.8) is amended by Sec. 22-465 to exclude "one- and two-family dwelling units," unless the fire code official finds a fire-flow, apparatus-access or other life-safety reason to require one (gated communities are named as an example). Where a sprinkler system is required anyway or installed voluntarily, Sec. 22-466 bars using NFPA 13D and instead requires the system be installed under IRC section P2904.

Violations & Fines

There's no baseline sprinkler mandate for one- and two-family homes, so no violation applies in most cases. Where the fire code official has specifically required a system for fire-flow or access reasons, failing to install and maintain it is enforced under the fire code's standard penalty provisions.

Frequently Asked Questions

Does Greeley require sprinklers in new single-family homes?
No. Sec. 22-95 deletes the IRC's R313.2 sprinkler mandate for one- and two-family dwellings entirely, and the fire code excepts them from its Group R sprinkler rule too.
Can the city ever require a sprinkler system in a house anyway?
Yes, if the fire code official finds a fire-flow, apparatus-access, or other life-safety issue, some gated communities are named as an example, under Sec. 22-465's exception.
