Rifles and shotguns for sale at Bristlecone Shooting, Training and Retail Center in Lakewood, Colorado, on Thursday, Jan. 16, 2025. (Jesse Paul, The Colorado Sun)House Bill 1062: Stealing a firearm in Colorado would be a Class 6 felony, punishable by up to 18 months in prison, under this measure awaiting the governor’s signature. Right now, the penalty for stealing a firearm in Colorado depends on the value of the weapon. Stealing a gun worth less than $300 is a petty offense, punishable by up to 10 days in jail. Gun theft currently becomes a felony, and carries the possibility of prison, only when the weapon stolen is worth more than $2,000.

House Bill 1238: This bill requires a gun show promoter to prepare a security plan and submit that plan to each local law enforcement agency with jurisdiction over the gun show.

House Bill 1250: Under this measure awaiting the governor’s signature, starting in the fall, schools would have to provide gun violence prevention materials to parents at the beginning of each academic year and also post them on their website.

Senate Bill 145: This measure, awaiting the governor’s signature, would require that sellers of goods or services give buyers a chance to cancel an automated subscription before it renews through a one-step process. That process could include a link or an in-person cancellation option, but the cancellation option needs to be accessible, at a minimum, through the same medium by which someone subscribed to the good or service in the first place.

House Bill 1093: This new law, signed by Polis in March, expands the state’s prohibition on anti-growth laws in urban areas. Starting July 1, affected local governments will be barred from adopting land use codes that reduce how much residential density is allowed in their community overall. Under the new rules, any reductions to housing density on one piece of land would have to be offset by increases elsewhere.

House Bill 1207: Insurers would be prohibited from refusing, canceling or increasing the cost of coverage for residential property owners based on the breed of their dog under this measure awaiting the governor’s signature.

Senate Bill 20: The Colorado Attorney General’s Office and Department of Law would be given the power to enforce tenant protection laws and sue landlords over violations of certain state housing laws under this measure, which is headed to the governor’s desk. The measure would similarly empower cities and counties to enforce tenant-landlord laws. That would mark a change from the current legal landscape, in which tenants generally have to fight court battles on their own when they face substandard living conditions or other violations of state housing laws.
Health care

Amanda Adams, second from right, the interim nurse manager, runs emergency staff through their first practice scenario of the day. (Kathryn Scott, Special to The Colorado Sun)House Bill 1002: With this measure, signed by Polis, lawmakers are trying to make sure health insurance companies cover behavioral health, mental health and substance use disorder treatments as thoroughly as they cover physical health issues. The bill prohibits health insurers from denying care based on a patient’s current or future behavioral health or substance use disorder. The law takes effect next year.
House Bill 1027: This bill, which has been signed into law, updates Colorado’s vaccination requirements for children attending public schools. It lessens the state’s reliance on vaccine recommendations from the federal government in response to the Trump administration’s Health and Human Services Secretary Robert F. Kennedy Jr., who prior to his current position was a prominent opponent of vaccine policies. When setting immunization standards, the law directs the state Board of Health to also consider guidance from the American Academy of Pediatrics, the American Academy of Family Physicians, the American College of Obstetricians and Gynecologists and the American College of Physicians. The law has several other public health law updates, including repealing a committee that advises the governor during pandemics.
House Bill 1088: This measure is intended to prevent excessive, surprise charges for ambulance rides. It would limit how much ambulance services can charge for transporting patients and would require health insurance companies to cover the cost, minus deductibles or copays. It would also require ambulance services to post their reimbursement rates online. The governor hasn’t signed the bill yet.

Senate Bill 48: All large-group health insurance plans in Colorado would have to offer consumers a plan that covers Glucagon-like peptide-1 medications, known as GLP-1 drugs, to treat obesity and pre-diabetes. Those include injectable medications like Wegovy and Ozempic. The measure, if signed by the governor, would take effect in 2027.

Senate Bill 129: This measure, already signed into law, is meant to shield abortion providers and patients, as well as transgender people and their doctors, from out-of-state investigations. The legislation will let health care providers omit their names from prescriptions they write and clarifies that Colorado governments, hospitals and insurers don’t have to comply with investigations into abortion and transgender care initiated in other states.
Senate Bill 130: This abortion-centered bill would define going into labor and certain pregnancy complications as “emergency medical conditions” and mandate that emergency departments and other medical facilities treat patients with such conditions. It also defines abortion as an emergency medical treatment when the procedure is necessary to stabilize a patient. It would give the attorney general the power to investigate violations and includes protections against retaliation for facilities that follow the rules. It hasn’t been signed by the governor yet.

The bill awaits the governor’s signature.
House Bill 1031: Law enforcement whistleblowers would get new protections against retaliation under this measure, which is awaiting the governor’s signature. The measure lays out specific forms of prohibited retaliation against officers who report misconduct. It also allows whistleblowers to seek damages if they are retaliated against. A similar bill failed at the Capitol in 2024 largely due to opposition from police and sheriffs.
House Bill 1058: This measure, which was signed into law by the governor, changes the process that’s triggered when someone charged with a crime pleads not guilty by reason of insanity. Those changes include requiring attorneys, state officials and the court to determine how long a sanity evaluation will take.

The measure would also implement more stringent reporting requirements for law enforcement agencies when submitting information about officers’ conduct to the database, including requiring that they provide more documentation about disciplinary actions taken against officers.
