Pueblo's Accessory Structures: The Rules That Matter

Every city handles accessory structures a little differently. In Pueblo, Colorado, there are 8 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Carport Rules

Pueblo Municipal Code §17-4-23 treats carports as accessory structures requiring a building permit (over 200 sq ft) and architectural review, with prefabricated metal pole carports allowed only under the narrow conditions in §17-4-23(d)(5).

Key details: Code: PMC §17-4-23. Permit Threshold: Over 200 sq ft (§17-4-23(c)(5)). Front Setback: Cannot encroach (§17-4-23(d)(4)d.). Prefab Metal Pole: Conditional (§17-4-23(d)(5)). Pre-1972 Lots: Required for prefab option.

Building a carport without the required Accessory Structure Application or building permit, placing a carport in front of the principal structure's setback, or installing a prefabricated metal pole carport that fails the §17-4-23(d)(5) conditions can trigger code-enforcement citations, stop-work orders, mandatory removal, and zoning fines.

ADU Owner Occupancy

Pueblo's Title XVII does not impose a blanket owner-occupancy condition on ADUs for long-term rental, and Colorado HB24-1152 (effective June 30, 2025) preempts any owner-occupancy mandate as a condition of building or operating an ADU in subject jurisdictions like Pueblo. HOA covenants and recorded deed restrictions may still impose private owner-occupancy requirements enforceable under Colorado CCIOA (C.R.S. § 38-33.3).

Key details: City Owner-Occupancy: Not required (long-term). State Rule (HB24-1152): Owner-occupancy preempted. STR Exception: Owner-occupancy allowed for STR <30 days. HOA Authority: CCIOA C.R.S. § 38-33.3.

City enforcement of owner-occupancy as a long-term rental condition is preempted by HB24-1152 after June 30, 2025. HOA owner-occupancy enforcement is civil under CCIOA — neighbors and association boards may file in Pueblo County District Court. Recorded deed restrictions can be enforced by parties with standing.

Pueblo is more permissive than most cities when it comes to adu owner occupancy. That said, there are still limits.

ADU Impact Fees

Pueblo charges standard building permit fees through PRBD plus separate water tap fees through the Pueblo Board of Water Works and sewer connection fees through the Pueblo Wastewater Department. ADUs sharing the principal dwelling's water and sewer service avoid most tap fees. Colorado HB24-1152 encourages but does not mandate fee waivers for small ADUs; Pueblo has not adopted a categorical ADU waiver as of 2026.

Key details: Building Permit: Scales with valuation (PRBD). Water Tap (PBWW): ~$4k-$7k new; $0 shared. Sewer Connection: Plant-investment charge applies. City Use Tax: 3.5% on materials. Categorical ADU Waiver: Not adopted (under study).

Permits will not issue until all fees are paid in full. Unauthorized connections to PBWW water service or city wastewater service result in service termination plus reconnection charges and back fees. Unpermitted construction is subject to PRBD stop-work orders and after-the-fact fees at doubled rates.

ADU Permits

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.

Key details: Zoning Authority: Title XVII (Pueblo Municipal Code). Permit Agency: Pueblo Regional Building Department. Building Code: 2021 IRC (locally adopted). State Preemption: HB24-1152 (eff. 6/30/2025). MPO Status: PACOG subject jurisdiction.

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.

ADU Rental Restrictions

Long-term rentals of Pueblo ADUs (leases of 30+ days) are permitted without owner occupancy under HB24-1152 after June 30, 2025. Short-term rentals (under 30 days) require a Pueblo short-term rental license from the City Sales Tax Office plus collection of the city's 3.7% sales tax and 4.3% lodging tax. HB24-1152 allows local governments to retain owner-occupancy conditions only for STR use, not for long-term rental.

Key details: Long-Term Rental: No city license required. STR License: Required (City Sales Tax Office). City Sales Tax: 3.7%. City Lodging Tax: 4.3%. STR Owner-Occupancy: Allowed under HB24-1152.

Operating an unlicensed STR is a violation of Pueblo's licensing and tax codes with civil penalties, back taxes, and abatement orders. Failure to remit city sales and lodging tax accrues interest and penalties under Title XIV (Taxation) and creates personal liability. Long-term rental in a zone district that does not permit dwelling use is enforced by Pueblo Code Enforcement.

Shed Rules

Small sheds under 200 square feet generally do not require a building permit in Pueblo. Larger structures require permits and must meet setback requirements.

Key details: No Permit Needed: Under 200 sq ft. Permit Required: 200+ sq ft. Setbacks: Must comply with zoning code. Easements: Cannot build in easements.

Unpermitted structures over the threshold must be retroactively permitted or removed.

If you are coming from a city with tighter rules, you will find Pueblo gives residents more flexibility on shed rules.

ADU Rules

Pueblo allows accessory dwelling units in certain residential zones under the zoning code. ADUs must meet size, setback, and building code requirements. Colorado supports ADU-friendly policies.

Key details: Allowed: In certain residential zones. Types: Attached or detached. Permits: Required from Pueblo Regional Building. State Support: Colorado encourages ADUs.

Unpermitted ADUs face enforcement. Non-compliant structures must be brought to code.

Garage Conversions

Garage conversions in Pueblo require building permits. The conversion must meet building code for habitable space. Converting to an ADU may be subject to additional zoning requirements.

Key details: Permit: Required for all conversions. Building Code: Must meet habitable space standards. ADU: May be subject to ADU rules. Parking: Replacement may be required.

Unpermitted conversions face code enforcement. The space may need to be restored or properly permitted.

The Bottom Line

Compared to many U.S. cities, Pueblo gives residents more room on accessory structures. 2 of the 8 rules here are rated permissive. But permissive does not mean unregulated. There are still requirements, and the city does enforce them when violations are reported.

All of the above reflects Pueblo's municipal code as of our last review. If you need specifics on fines, exemptions, or filing requirements, the detailed ordinance pages linked above have the full breakdown.
