Stays of 30 days or longer are not short-term rentals under BRC 6-3-7 and require no STR license. Boulder hosts may run extended home-shares, sublets, and traditional roommate arrangements outside the STR framework provided they comply with rental and zoning rules.
Boulder defines a short-term rental as a stay under 30 consecutive days at BRC 6-3-7. Bookings of 30 days or more are treated as standard residential leases or sublets, exempt from STR licensing. This carves out a permissive lane for furnished mid-term rentals, traveling-nurse housing, and academic visitors at CU-Boulder. Hosts must still respect occupancy limits, parking rules, and any HOA covenants. Mid-term rentals are not subject to lodging tax but may owe sales tax on furniture rentals and utilities.
Booking nominally 30-day stays but allowing early checkout to evade STR rules can be treated as licensing fraud and prosecuted under BRC 5-2-4.
