HB24-1152 is the official Colorado bill to reference when discussing the state’s ADU framework. Homeowners and local partners should still confirm whether their jurisdiction, parcel, timing, and project type are covered by the law and by local implementation rules.

What to verify first
- Applicability: whether the property is in a covered jurisdiction and zoning context.
- Local implementation: what local standards still apply to size, access, parking, design, utilities, or occupancy.
- Utility feasibility: whether the site can connect or expand service without disproportionate cost.
- Timeline: whether rules are adopted, pending, paused, or still moving through a local process.
Policy is the doorway, not the project
The real question is not simply whether ADUs are allowed. It is whether this parcel can support this ADU type at a cost and timeline that still makes sense.
For municipalities and counties, the implementation challenge is different. The work is to translate state law, local code, utility capacity, public messaging, grant requirements, and staff workflow into a process residents can actually use.
