This law codifies and clarifies mental health parity requirements for insurers, ensuring that individuals receive the same coverage for mental health and behavioral services as they do for physical care.

This law streamlines the permitting process for wireless telecommunication providers in the state by setting deadlines for local governments to approve applications.

House Bill 1090: Protections against deceptive pricing practices

This law requires sellers to disclose the maximum total price of a good or service, including any additional charges or fees.

This law requires car insurance companies to ask claimants whether a car seat was in their vehicle at the time of the accident, and, if so, to cover the replacement cost of the seat.

House Bill 1236: Residential tenant screening

This law clarifies that individuals applying for housing using a housing subsidy are not required to include their credit history report, credit score, or adverse credit event in their tenant screening report.

House Bill 1238: Gun show requirements

House Bill 1285: Veterinary workforce requirements

This law requires the state’s Board of Veterinary Medicine to adopt rules regarding the education, accreditation and scope of practice for veterinary professional associates, a first-of-its-kind position established through a ballot measure during the 2024 election.

House Bill 1295: Food truck operations

This law establishes a statutory definition of “mobile food establishment.” It creates a reciprocal food safety licensing agreement between the City and County of Denver and other local governments throughout the state, as food truck operators in Denver are currently unable to obtain licenses from the Colorado Department of Public Health and Environment.

Senate Bill 004: Regulating child care center fees

This law allows health insurance companies to deliver legally required notices and documents electronically if the recipient consents. The law also requires insurers to provide paper communications upon request.

Senate Bill 053: Protecting wild bison

Senate Bill 158: State agency procurement and disposal certain items

This law establishes procurement rules for how state agencies purchase firearms and other items regulated under the National Firearms Act, requiring bidders and contractors to provide licensing information, safety documents, and theft histories.

The law also prohibits Colorado residents and businesses from complying with out-of-state civil, criminal or regulatory inquiries regarding individuals or entities involved in certain healthcare-related activities.
