Wheat Ridge moves to 2024 building code; council agrees to require sprinklers in new townhomes with delayed implementation

Wheat Ridge City staff told council Monday they will update local building regulations to the 2024 model codes and seek direction on a set of local amendments; councilors gave direction to require automatic fire sprinklers in new townhome construction but not to impose a blanket new‑construction sprinkler requirement for detached single‑family homes at this time.

Staff overview and code update scope

Staff said the city currently enforces the 2018 model codes and is proposing adoption of the 2024 codes with local amendments consolidated into a single administrative chapter to improve clarity for customers and contractors. The package includes defined valuation methodology for permit fees, retention of the mid‑roof inspection requirement for roofing work, and a variety of administrative and technical updates intended to make permit review more predictable. Staff said their philosophy is to treat the building division as a collaborative partner to move projects to completion rather than as a barrier.

Residential sprinkler discussion and council direction

Automatic residential sprinklers were the focal point of council discussion. Staff described survey feedback: the development community and the building code advisory board generally preferred to keep sprinkler requirements optional, while local fire districts urged broader mandatory sprinkler coverage, notably for attached products. Fire Marshal Steven Parker and other public‑safety staff recommended expanding sprinkler requirements, at least to multifamily and attached housing.

After extended discussion of public‑safety benefits, construction costs, water‑district tap and meter implications, and insurance impacts, councilors reached consensus to require automatic fire sprinklers in new townhome construction and to implement that change with a delayed applicability to allow water districts and developers time to adapt. Councilors explicitly declined at the meeting to adopt a near‑term requirement extending mandatory sprinklers to all detached single‑family homes and duplexes; several councilors asked staff to continue exploring ADU‑related impacts and fire separation options.

Technical clarifications discussed in the meeting included: - Staff said the expedited implementation for townhome sprinklers would likely use NFPA 13D‑style residential systems, and that water‑district practices vary: some districts require a separate tap for sprinkler service while others allow private risers or shared lines; anticipated tap‑fee upsizing (e.g., from 3/4" to 1") can materially increase developer costs. - The city will test implementation approaches and coordinate with affected water districts; staff proposed a delayed effective date to permit engagement with districts and the development community.

Other amendments and next steps

Staff flagged a set of additional local amendments (administration, valuation used for permit fees, mechanical/energy clarifications, and existing‑building rules) that will appear in the ordinance. Staff noted the mid‑roof inspection for roofing (ice and water barrier inspection) will remain. The building code advisory board and the contracted plan‑review consultants (Charles Abbott Associates) reviewed the proposed changes, and staff plans to present a draft ordinance in October. Council asked for clear public communications and a short “what contractors need to know” one‑page summary when the ordinance is released for public review.

Ending: staff will prepare ordinance language and a phased implementation plan for the townhome sprinkler requirement; remaining code amendments will be presented to council in October for adoption.
