Colorado laws taking effect July 1 include changes to gun regulations, domestic violence policies

While legislation in Colorado becomes law the moment the Governor signs it, that doesn’t always mean the new rules are immediately enforced. In many cases, there’s a built-in delay, with some laws taking months—or even over a year—to officially go into effect. This gives state agencies, businesses, and the public time to prepare for the changes.

As July 1 approaches, a new wave of policies passed during the last two legislative sessions is set to become active. These laws cover a range of issues, from public safety and education to environmental protection and consumer rights. Below is a breakdown of the key measures that will take effect starting July 1, shaping how Coloradans live, work, and interact with state systems.
