Pueblo permits accessory dwelling units under Title XVII (Zoning) of the Pueblo Municipal Code in designated residential zones. Plan review, building, electrical, plumbing, and mechanical permits are issued by the Pueblo Regional Building Department (PRBD). Colorado HB24-1152, effective June 30, 2025, requires Pueblo as a PACOG MPO subject jurisdiction with population over 1,000 to allow at least one ADU on every single-family lot through an administrative review pathway, prompting an active Pueblo Title XVII update.
Pueblo's existing ADU framework sits in Title XVII (Zoning) of the Pueblo Municipal Code, which allows accessory dwelling units as accessory uses in certain residential zone districts subject to district-specific standards on size, setbacks, and design. Applicants submit a zoning verification through the Pueblo Department of Planning and Community Development (719-553-2489), then a full plan set to the Pueblo Regional Building Department (PRBD), which serves the City of Pueblo, Pueblo County, and several surrounding municipalities. PRBD reviews construction against the 2021 International Residential Code as locally adopted, including egress, light, ventilation, and energy provisions. Standard setbacks under Title XVII for accessory structures are typically 5 feet from side and rear lot lines, with corner-lot sight triangles preserved. Colorado HB24-1152, codified at C.R.S. § 29-32-101 et seq. and operative June 30, 2025, treats Pueblo as a subject jurisdiction because the city falls inside the Pueblo Area Council of Governments (PACOG) Metropolitan Planning Organization and exceeds 1,000 population. The statute requires at least one ADU per single-family lot through administrative-only review (no neighbor vetoes), forbids ADU-specific parking minimums, restricts owner-occupancy mandates, and prohibits design standards more restrictive than those applied to the principal dwelling. Pueblo is amending Title XVII to comply.
Building an ADU without a permit violates the Pueblo Municipal Code and the PRBD-adopted building code. PRBD can issue stop-work orders, require after-the-fact permitting at doubled fees, and order the removal of unpermitted construction. Zoning violations under Title XVII are enforced by Pueblo Code Enforcement; recorded violations impair clear title and refinancing.
