, the ban on 3D-printed guns, goes into effect July 1. The law expands on Colorado’s prior ban on firearms without serial numbers, known as “ghost guns,” by prohibiting the use of 3D printers or computerized milling machines to manufacture firearms or components like large-capacity magazines and rapid-fire trigger activators.

Polis had threatened to veto an earlier version of the bill that included a prohibition on selling or distributing “digital instructions” needed to print the firearms or their components. Sponsors stripped that measure out before it reached his desk.

increases the overtime threshold for some agriculture workers from 48 hours to 56 hours outside of the peak harvest times. The measure passed narrowly — and with more Republican than Democratic votes — in each chamber of the legislature. Democrats hold a nearly two-to-one majority in each chamber.

Those new overtime provisions go into effect in Jan. 1, 2027. Proponents of the measure argued it’s necessary for a struggling and vital industry and that it would help workers because they could be scheduled for more hours. Opponents argued that bill — voted on weeks after lawmakers renamed a holiday for farmworkers — would mean more exploitation of an already economically vulnerable population.

Polis also signed on Monday. That measure seeks to protect children used in online content creation by requiring the content creators to set aside a portion of proceeds until the child reaches adulthood and allow adults or emancipated minors who were used in content as children to have that content deleted upon request, among other protections.

Once it goes into effect on Jan. 1, 2028, will only allow pet stores to host animals from adoption or rescue services, so long as the stores don’t charge fees and the animals are sterilized. It otherwise prohibits those stores from selling dogs and cats in an effort to curb commercial breeding and sales from “puppy mills.”

, there are seven pet stores in the state licensed to sell the animals and five more that serve as brokers.

As Polis prepared to sign the bill, five black-and-white, 13-week-old puppies — Benedict, Daphne, Violet, Eloise and Hyacinth — lounged, climbed over one another, leaned into a reporter’s mic and cuddled in a pair of pens on the Capitol foyer’s floor. All of them .

The governor also brought his dog, Gia, who hopped off her chair and wandered under the bill-signing table to investigate the newcomers.

“We’re sending a very powerful message with this bill — first of all: Adopt, don’t shop. Little Gia is here, we adopted her 16 years ago,” said Polis, who had scooped up the little brown dog. His husband, animal rights advocate Marlon Reis, stood beaming nearby.

“If you do want to purchase … some people want (a) purebred or a specific breed, (and) there are many wonderful home breeders, legitimate breeders in our state, people who have a litter of dogs in their home and sell them,” Polis added.

The new law will not apply to the sale of specially trained animals — like those used by law enforcement, hunters or people with disabilities.

The bill took eight years to pass, according to Polis and the bill’s primary sponsor, House Majority Leader Monica Duran. Duran officially named the bill after her late Pomeranian, Pistol.

Polis said 26 jurisdictions in Colorado have banned puppy mill sales in retail stores. Denver joined them when its City Council passed an ordinance last year, though the city had no stores selling dogs and cats at the time. Several other states, including and , have adopted similar bans.

HB-1011 was also sponsored by Democrats Rep. Karen McCormick and Sens. Robert Rodriguez and Dylan Roberts. The measure passed the Senate earlier this month on a 19-16 vote, with all Republicans and some Democrats opposed. It had cleared the House 44-21, with only one Republican — Rep. Rick Taggart — voting in support.

“Today, this bill has lived in my heart for eight years,” an emotional Duran said. “Eight years of conversations, eight years of setbacks, eight years of (the time for this law) being not yet, not now and maybe never. But here we are.

“And today, I don’t stand alone. I stand here with every voice that refused to give up on the animals who could not speak for themselves.”

Ahead of the bill signing, the Best Friends Animal Society hailed the legislation and expressed hope it would help reduce euthanization of shelter pets in Colorado by increasing adoptions. In a news release, the group cited recent data showing a nearly 16% increase last year in the killing of shelter pets across the state, though the vast majority of shelters are considered “no-kill.”

“Best Friends has been working to make the country no-kill and it����ap incredible to see the continued momentum in Colorado to help save every healthy and treatable dog and cat,” the society’s CEO, Julie Castle, said in a statement.

Polis signed into law administratively on Monday, without a signing ceremony. The law, which takes effect July 1, will require courts to keep records of petitions for a legal name change from public view if the petitioner is younger than 18 at the time of filing.

The law is aimed at protecting the privacy of trans youths and their families.

The original version of the bill also would have directed family court judges to consider a parent’s acceptance of a child’s gender identity when determining custody. That provision, however, was stripped out.

A spokesperson for Polis said at the time that the governor was worried that the provision would be inadvertently harmful to the children and families it sought to protect.

This year’s builds off the landmark 2019 measure creating the state’s red flag law. That law allows certain people to petition the courts for a temporary restraining order to prohibit people deemed a danger to themselves or others from possessing firearms.

The newest expansion grows the list to include behavioral health co-responders and allows for health care and educational institutions to file the petitions.

“This law will help protect Coloradans and our communities from senseless gun violence,” Polis, a Democrat, said in a signing statement. “Colorado’s red flag law has been successfully used over 370 times though 2024, keeping Coloradans safe across the state.

“This updated legislation builds on our strong law to promote safe gun ownership and expands the list of those who can keep our communities safe through petitioning a protection order.”

The new law takes effect immediately. It was sponsored by Sens. Tom Sullivan and Julie Gonzales and Reps. Meg Froelich and Jenny Willford, all Democrats.

“Our law will help prevent gun crimes and suicides to save countless Colorado lives while safeguarding people’s rights through a proven process,” Froelich said in a news release after the signing. “… We’re strengthening this gun violence prevention law to save more lives and make Colorado a safer place to live for all.”

Polis signed the original red flag bill into law during his first year in office. This expansion was passed during the term-limited governor’s final legislative session.

His tenure has been marked by a steady increase in firearm regulations.

Gov. Jared Polis’ office signed the legislation into law in a private signing ceremony with sponsors Tuesday morning, according to his office. The final legislative vote, on Monday, came a week after it was heard in its first committee and as lawmakers raced to stop one more César Chávez Day, recognized every March 31, from being celebrated.

The bill passed both the Senate and House unanimously. It was sponsored by House Majority Leader Monica Duran and Rep. Lorena Garcia and Sens. Lisa Cutter and Jessie Danielson, all Democrats.

On March 18, The New York Times published a that found Chávez, who died in 1993, sexually abused numerous women and girls. Polis “is glad the legislature took action to rename César Chávez Day in light of these heinous allegations, allowing the state to use the day to celebrate and honor Colorado farm workers,” spokesman Eric Maruyama said in a statement.

States across the country have moved quickly to rename the holiday to honor the movement, not the man. Colorado recognizes March 31 as a voluntary legal holiday, with state offices remaining open.

But despite the speed, tensions among lawmakers regarding how best to move forward have boiled to the forefront.

On Friday, the Senate amended the bill to rename the holiday only for the next two years and to require future legislative action to adopt a name for future observances. The House accepted the changes Monday in order to send the bill to Polis’ desk, but the sponsors made their displeasure clear.

“This is not the bill I fought for, and it is not what communities have asked for,” Duran told colleagues during the final vote Monday afternoon. “A two-year sunset puts an expiration date on dignity. It tells farmworkers and survivors that their truth comes with a timeline. That’s not justice. That’s compromise.”

But, she continued, “walking away does not move (survivors) forward, and I will not walk away from them.”

Sen. Julie Gonzales, a Denver Democrat, ran the amendment Friday. She said previously that she wanted to create space so the Latino community and survivors could decide the best long-term path forward.

Gonzales said that in her office she has a signed portrait of Dolores Huerta, the co-founder of the National Farm Workers Association, along with Chávez — and one of his victims.

“She has always been an inspiration to me, and to countless others,” Gonzales said in a statement following the House vote. “Her strength as a leader in the fight for justice and as a survivor is unparalleled. It is my hope that, over the coming year, community members will process, metabolize, and heal from the devastating news that led to the change in the holiday’s name.

“Colorado has long been home to trailblazers, and I trust our community to identify leaders worthy of recognition. I also hope that the process itself will lead to healing. In the meantime, I look forward to celebrating Farmworkers Day (on Tuesday).”

This year’s requires large social media platforms to comply with search warrants within 72 hours and to create streamlined processes for law enforcement to file search warrants. Surrounded at the signing ceremony by people holding portraits of deceased loved ones, Polis said the new law would ensure that social media companies turn over records “before the trail goes cold.”

“It is incredibly important to make sure that our online partners, whether they’re marketplaces and whether they’re social media, respond promptly when needed by law enforcement,” Polis said. “It’s everything from helping to track down stolen bikes and cars to helping protect the lives of Coloradans from dangerous drugs.”

Sponsors of the bipartisan law thanked the governor for signing the measure — and also lamented that it was ever necessary.

“I don’t know of another instance where somebody could knock on your door, give you a warrant, and you could say, ‘I’ll get to it when I get to it,’ ” said Rep. Andy Boesenecker, a Fort Collins Democrat and sponsor of the bill. “That privilege does not exist for anybody else in our society. I think, for me, what this bill says is that social media companies have the same sense of obligation that we all should have to respond in a timely fashion, and not hinder investigations.”

The measure was also sponsored by Rep. Jarvis Caldwell, a Colorado Springs Republican, and Sens. Lisa Frizell, a Castle Rock Republican, and Dylan Roberts, a Frisco Democrat.

, a supporter of the bill, held a portrait of her son, 18-year-old Max Osterman, as Polis signed the bill. Max Osterman died in 2021 after he bought a pill laced with fentanyl through Snapchat.

She said the company dragged its feet with disputes about the warrant, undermining the pursuit of justice for her son.

“Had this bill been in place when they were doing my son’s investigation, perhaps the dealer would not have killed how many people after my son,” Osterman said. “The information would have been provided, and (the dealer) would have been doing time for my son’s death.”

The provision was originally part of , a more sweeping set of social media regulations that Polis vetoed last year. Polis said then that he had broader concerns that the bill would hurt privacy, freedom and innovation, and “potentially subjects all Coloradans to stifling and unwarranted scrutiny of our constitutionally protected speech.”

The legislature attempted, but ultimately failed, to override that veto.

A separate measure in this year’s legislative session, , also seeks to require social media companies to comply with warrants within 24 hours, as well as flag to local law enforcement when a user posts specifics threats on the platform and the platform takes action against the user. That measure was introduced in response to the Evergreen High School shooting in September.

HB-1255 has cleared its first committee but is still awaiting a full hearing from the House.
