Broomfield, CO Accessory Structures: ADU Rental Restrictions (2026)

The short-term rental ban sits inside the broader accessory dwelling unit standards of section 17-32-160, which otherwise let a homeowner build one ADU per parcel up to 800 square feet or 50% of the principal home's footprint. Because subsection (E) points to chapter 5-39, Broomfield's short-term rental licensing chapter, for the definition of a short term rental, an ADU address cannot be added to that licensing program at all; it is not merely subject to extra conditions, it is excluded from eligibility outright. Every ADU owner also records a declaration of use under subsection (I) stating the unit's size and location and confirming ongoing compliance with the accessory dwelling unit rules, which gives the city a paper trail to check against short-term rental listings tied to the same address.

The restriction applies regardless of whether the ADU is located within the principal dwelling, attached to it, or fully detached, and regardless of the unit's size or design. Nothing in section 17-32-160 or in chapter 5-39 carves out an exception for owner-occupied properties or for occasional rentals; the eligibility bar is categorical.
