What changed

Colorado Bill HB26-1114, introduced for the 2026 Regular Session, aims to significantly alter local zoning regulations by prohibiting subject jurisdictions from requiring lot sizes larger than 2,000 square feet for single-family homes, effective October 1, 2031. The bill also seeks to prevent minimum lot frontage, setback, open space, or maximum lot coverage requirements that effectively prohibit single-family home construction on a 2,000 square foot lot. Certain parcel types are exempted from these new requirements.

Local governments in Colorado will need to review and potentially revise their zoning ordinances to comply with this bill if it is enacted. The primary implication is a reduction in minimum lot size requirements, which could facilitate increased housing density. Compliance will be mandatory for "subject jurisdictions" by October 1, 2031. Failure to comply could lead to legal challenges or state-level intervention, though specific penalties are not detailed in this summary.

What to do next

Review Colorado Bill HB26-1114 for potential impact on local zoning ordinances.
Prepare to revise local minimum lot size and dimensional requirements to comply with a 2,000 sq ft limit for single-family homes.
Ensure compliance with the effective date of October 1, 2031.
