Operating rules

Primary residence: Yes
Min stay (nights): —
Max nights / year: —
Max occupancy: All advertisements must disclose the maximum allowed unrelated occupancy, and operators must follow the city's occupancy limits. The SPECIFIC number of unrelated persons permitted was NOT quote-anchored to an official page in this pass, and web search surfaced City Ordinance No. 8651 (adopted March 6, 2025) that repealed a prior occupancy section — so the current numeric occupancy limit is unverified and needs_review.
Zoning-restricted: No
Cap on licenses: No

Grandfathering: None identified.

Zoning: No separate STR-specific zoning district restriction identified; STRs are permitted citywide provided the unit is the operator's licensed principal residence. Permanently affordable units are not eligible.

Because each STR must be the operator's principal residence and the operator must hold >=50% ownership, an operator is effectively limited to one STR; no separate numeric citywide license cap was found.
Permanently affordable / deed-restricted affordable units cannot be licensed as short-term rentals — official application page: 'The property may not be a permanently affordable unit.'
'Short-term' is defined as rentals of 29 days or less at a time; no minimum-night requirement and no annual maximum-night cap were found in the official pages.
NEEDS_REVIEW: the exact current unrelated-occupancy number is unverified; Ordinance 8651 (Mar 6, 2025) and other 2025-2026 ordinances (8715, 8743) may have altered occupancy provisions — confirm against the current Boulder Municipal Code Title 10, Chapter 3 before relying on any specific number.
