Can I operate an investment STR in Boulder if I don't live there?
No. Boulder restricts STRs to the operator's principal residence — defined as the property where they live more than 50% of the year. Non-primary investment properties cannot obtain a Rental Housing License for STR purposes. The city verifies residency through utility records and tax filings.
What happens if Boulder decides I'm not truly a primary resident?
If your primary residency documentation is found insufficient at verification, your license application will be denied or your existing license revoked. Boulder has expanded its verification program and is cross-referencing multiple records. If you split time between locations, confirm you meet the >50% threshold at the Boulder address.
Is Boulder likely to impose additional restrictions on STRs?
Yes. City Council is actively reviewing proposals for a night-cap on principal residence STRs and expanded residency verification. Boulder's progressive housing politics make further restrictions more likely than loosening. Operators should monitor council proceedings for 2025 votes.
