Boulder caps unhosted whole-home short-term rentals at a limited number of nights per year under BRC 6-3-7. The cap protects neighborhood character while letting residents earn supplemental income during peak CU events and travel periods.
BRC 6-3-7 caps the number of nights that a primary residence may be rented out as a whole-home STR while the host is away. The night limit, set by city council and reviewed periodically, prevents de facto investor conversion of homes to year-round vacation rentals. Hosted stays where the licensee is present do not count toward the cap. Operators must log every booking through Boulder's licensing portal, and platforms like Airbnb share data with the city under CO 29-29-103-compatible agreements. Repeat overage triggers license revocation.
Exceeding the annual night cap risks license revocation, citation under BRC 5-2-4, and exclusion from re-licensing for a defined cooling-off period after enforcement.
