HB 25-1093 Colorado House · 2025 Regular Session

Limitations on Local Anti-Growth Land Use Policies

Summary
The act expands the definition of an anti-growth law, which local governmental entities are generally prohibited from enacting or enforcing, to include a generally applicable land use law that, in census urban areas as defined by the United States census bureau, explicitly decreases the permitted residential density or residential uses of land to a lower residential density or fewer residential uses than were allowed by the land's usage and zoning as of July 1, 2025, without ensuring a corresponding increase of residential density or residential uses elsewhere in the jurisdiction. The act provides that certain limitations on anti-growth laws do not apply to land that contains or is directly adjacent to a wildlife crossing structure. The act also permits a municipality to seek a judicial determination as to the legality of a proposed municipal initiative for a land use ordinance that restricts or limits the development or use of land that is submitted to the legislative body of the municipality, allows the owners of a property that is specifically subject to the proposed ordinance and persons designated as representing the petition proponents to intervene in the proceeding, and tolls the period within which the municipality is required to adopt the proposed initiated ordinance or call an election during the pendency of the judicial determination. (Note: This summary applies to this bill as enacted.)

MINOR
This bill was amended to clarify how it defines 'anti-growth laws' and to expand the ability for property owners to challenge land-use restrictions. The changes make the definition of anti-growth laws more specific about what counts as a decrease in residential density, and they allow more parties to intervene in legal challenges against new land-use ordinances.
Scope change
The bill's scope was expanded to include more specific criteria for what constitutes an anti-growth law and to allow additional parties to participate in legal proceedings related to land-use restrictions.
DEFINITION

The definition of 'anti-growth law' was rewritten to more clearly specify that laws explicitly decreasing permitted residential density in census urban areas count as anti-growth laws.

ELIGIBILITY

Property owners specifically affected by a proposed land-use ordinance and designated representatives of petition proponents were added as parties entitled to intervene in legal proceedings challenging the ordinance.

REQUIREMENT

The language regarding tolling of time periods for adopting ordinances was reorganized and clarified to ensure legal procedures are not delayed during related legal actions.
