Short answer: Since July 1, 2024 (HB24-1007) Colorado cities cannot limit the number of unrelated people living together based on family relationship. Since June 30, 2025 (HB24-1152) larger Front Range cities must allow one ADU on single-family lots. Cities still control rental licenses, short-term rentals, permits and safety codes.

Questions people ask
Does HB24-1007 let me rent to as many people as I want?
No. It stops limits based on family relationship, but building, fire and health codes still limit how many people can safely live in a home, and HOAs may have rules.
Do I need a permit to rent my basement?
If the basement was finished without permits, or you are adding a kitchen or separate unit, you may need permits. Rental and safety rules vary by city.
Where can I read the state rules?
The Colorado Department of Local Affairs (DOLA) publishes guidance on both HB24-1007 and HB24-1152 on its website.
