Fort Collins does NOT require owner occupancy for ADUs. The 2024 Land Use Code update removed the owner-occupancy clause from LUC Division 3.8.30 to align with Colorado HB24-1152 (effective 6/30/2025), which prohibits owner-occupancy requirements as a condition of ADU approval in jurisdictions of 1,000+ population.
Earlier Fort Collins ADU rules required the property owner to occupy either the primary dwelling or the ADU as their primary residence. The 2024 LUC update eliminated this requirement to align with state policy direction and Colorado HB24-1152. HB24-1152 expressly prohibits municipalities from conditioning ADU approval on owner occupancy. LUC Division 3.8.30 contains no owner-occupancy clause. No deed restriction is recorded at permit issuance. Both the primary dwelling and the ADU may be rented to separate tenants under standard long-term lease terms. Short-Term Rental (STR) operation remains subject to separate Fort Collins City Code Chapter 15, Article XVI requirements — STR licensing has its own primary-residence rule independent of ADU status.
There is no penalty for non-owner-occupancy of a Fort Collins ADU. Violations of the Short-Term Rental ordinance (Chapter 15, Article XVI) are separate offenses with fines up to $2,650 per occurrence and license revocation. Operating unlicensed long-term rentals at non-conforming density violates LUC 1.4.9 with civil penalty up to $1,000 per day.
