Colorado’s new fiscal year brings July 1 laws on 3D-printed firearms, conversion therapy civil claims, and mobile home tax notices, while CDOT adds I-25 speed cameras and warns drivers about holiday traffic and wildfire risk.
Colorado entered the new fiscal year this week with several new laws taking effect, while other major 2026 policies are scheduled to phase in later this year or in 2027.
At the same time, state transportation officials are rolling out automated speed enforcement in another construction zone, warning drivers about heavy Fourth of July mountain traffic, and urging extra caution as fire restrictions cover western Colorado.
Here are the state policy and infrastructure updates to know this week.
A new Colorado law now prohibits the unlawful 3D printing of firearms and certain firearm components.
House Bill 26-1144 makes it unlawful to knowingly manufacture or produce a potentially functioning firearm, unfinished frame or receiver, large-capacity magazine, or rapid-fire device using 3D printing technology — defined broadly to include both additive manufacturing and subtractive manufacturing such as CNC milling.
The law includes exceptions for federally licensed firearm manufacturers, accredited gunsmithing programs, and certain instructors or students connected to those programs.
Note: Earlier versions of the bill also would have prohibited the possession and distribution of digital instruction files used to program 3D printers to produce firearms. That provision was removed before passage after Governor Polis signaled he would veto legislation that restricted the distribution of information. The signed law covers manufacturing only.
House Bill 26-1322 gives survivors of conversion therapy a new civil legal pathway.
The law allows an injured person to bring a civil claim against a licensed mental health professional — as well as entities that employed or supervised that professional — for harm caused by sexual orientation or gender identity change efforts.
The law also allows those claims to be filed without a time limitation, removing the prior two-year statute of limitations. If the injured individual is deceased, their personal representative may bring a survival action within five years of the individual's death.
House Bill 26-1120 changes how counties handle delinquent property tax notices for mobile homes.
Beginning July 1, county treasurers must provide delinquent mobile home property tax notices in both English and Spanish. The notice must also explain how a mobile home owner can obtain language translation or interpretation services.
The law also changes parts of the process for mobile home tax liens, redemption periods, and collection procedures.
Not every major law passed this year is fully operational yet.
Senate Bill 26-155, signed by Governor Polis in early June 2026, creates the Strengthen Colorado Homes Enterprise within the Division of Insurance. The enterprise — already established by the signing — is designed to help reduce hail and windstorm losses by supporting grants for resilient roof systems, and to study insurance risk in high-risk wildfire areas of the state.
However, the insurance fee that funds the enterprise does not begin until no sooner than calendar year 2027. Insurer filing requirements tied to the enterprise also take effect no sooner than January 1, 2027.
House Bill 26-1224 strengthens financial protections for mobile home park residents, including more disclosure when a park owner intends to sell, good-faith requirements for sales, and limits on how much of a registration fee can be passed on to residents.
This law is scheduled to take effect January 1, 2027.
The Colorado Department of Transportation began issuing automated speed warnings June 30 in the I-25 and US 50B Interchange Reconstruction work zone in Pueblo.
This is the third active corridor in CDOT's Colorado Speed Enforcement Program, which uses Automated Vehicle Identification Systems to identify vehicles traveling an average of 10 mph or more over the posted speed limit in high-risk corridors such as construction zones.
Warnings will be issued for at least 30 days before civil penalties begin. CDOT says $75 civil penalties in the I-25 and US 50B corridor are expected to begin July 30.
Once penalties begin, violations will be mailed to the registered vehicle owner. CDOT says the violations will not add points to a driver's license.
CDOT is warning drivers to expect heavy Fourth of July travel on mountain highways, especially along the I-70 Mountain Corridor.
Because Independence Day falls on a Saturday this year, CDOT expects westbound I-70 traffic to peak Friday, July 3, starting around 10 a.m. Return eastbound traffic is expected to be heaviest Sunday afternoon into Sunday evening.
To avoid the worst congestion, CDOT recommends passing through the Eisenhower-Johnson Memorial Tunnel before 9 a.m. Friday when heading west and around 6 p.m. Sunday when returning east.
The holiday travel period also overlaps with high wildfire risk. Drivers should check COtrip before leaving, watch for sudden wildfire-related road closures, and avoid anything that could spark a roadside fire — including tossing cigarettes from vehicles, dragging trailer chains, or overheating brakes on steep descents.
Colorado's 2026 primary election was held Tuesday, June 30.
Unofficial results are shaping the legislative, statewide, and congressional matchups for the November general election, but post-election processing is still underway.
Voters have until July 8 to fix signature or ID issues with their primary ballots through Colorado's BallotCure process.
County clerks will continue required processing, verification, and reporting steps before results are finalized.
This week brought a mix of new laws, phased-in policy changes, transportation enforcement, fire danger, and post-primary election processing.
For Colorado residents, the biggest immediate changes are the July 1 laws on 3D-printed firearms (manufacturing only — digital files are not covered), conversion therapy civil actions, and mobile home property tax notices.
For drivers, the main reminders are to slow down in work zones, plan around heavy I-70 holiday traffic, and take wildfire prevention seriously while fire restrictions remain widespread across western Colorado.
