Westminster, CO Short-Term Rentals: Occupancy Limits (2026)

C. 11-12-4,' folding every licensed Short-Term Rental into the City's general dwelling-unit occupancy standard rather than setting a separate STR-specific headcount. ' Section 11-12-4(B)(1) also requires habitable rooms to have at least a seven-foot ceiling height, with a room under five feet of ceiling height excluded from the floor-area calculation entirely. Section 11-12-4(B)(2)(b) lets the building official waive or modify these minimums only for narrow circumstances such as the birth or adoption of a child or a temporary medical-care need, none of which apply to a rented STR.

Because the STR Code incorporates this general standard by reference rather than restating it, a host must count both the total habitable area of the licensed premises and the area of each bedroom used for sleeping to determine the maximum lawful number of overnight guests, and Section 11-12-4(A) separately makes it unlawful to use a building for purposes other than those for which it was designed.
