Summary
Short-term rentals are illegal in Boulder without a city-issued license. Section 10-3-19(a) bars anyone from operating a short-term rental unless the city manager has issued a valid short-term rental license, and only a natural person, a trust with a natural-person beneficiary, or a qualifying nonprofit may hold one.
(a)Short-term rentals are prohibited unless the city manager has issued a valid short-term rental license for the property.(b)The city manager shall only issue a rental license for short-term rental to:(1)A natural person, whose name appears on the deed to the property;(2)A trust, if the beneficiary of the trust is a natural person; or(3)A not-for-profit corporation licensed pursuant to Section 501(c) of the Internal Revenue Code

Full Breakdown
C. " Subsection (b) narrows who can even apply: a natural person named on the property deed, a trust whose beneficiary is a natural person, or a nonprofit corporation licensed under Internal Revenue Code Section 501(c), and the city manager has discretion to reject a nonprofit's application if it conflicts with the chapter's goal of preserving long-term rental housing and blocking investor-owned short-term rentals. The application itself, under subsection (c), must include a Colorado driver's license or ID card showing the unit as the applicant's (or beneficiary's) address, a sworn statement that the unit is the applicant's principal residence, proof of 501(c) status for a nonprofit applicant, a certification that the unit has operational smoke detectors, carbon monoxide detectors, and other required life-safety equipment, and the names and phone numbers of two contacts able to reach the property within 60 minutes.
A licensed applicant must hold at least a 50 percent fee-simple ownership interest in the property under subsection (d) or (e), and the city manager cannot license a unit owned in fee by a non-tax-exempt entity, cannot license more than one short-term rental to the same applicant, and cannot issue both a short-term rental license and a standard rental license for the same unit under subsections (f), (m), and (n). New applications for most short-term rental licenses stopped altogether after February 1, 2019, under subsection (o)(7)(A); only renewals of unexpired licenses, and a narrower festival lodging license under subsection (q), remain available today.
Violations & Fines
Operating or advertising a short-term rental without a current license violates Section 10-3-19(a) and (l), and, like other Chapter 3 violations, draws the escalating $150/$300/$1,000 civil penalty schedule in Section 10-3-16(a)(1) plus possible license revocation. A licensee who no longer meets the ownership or principal-residence conditions in subsection (c) faces mandatory revocation under Section 10-3-16(a)(3), and unlicensed operation can also trigger the criminal fine of $500 to $2,000 per violation, or up to 90 days in jail, under Section 10-3-17.
