Building permits, zoning and land rules in Pueblo County, Colorado

Yes. Unincorporated Pueblo County requires permits for excavation, grading, fill and construction, including work performed by an owner¹. The county has adopted the 2021 International Building, Energy Conservation and Existing Building codes with amendments, plus the 2021 Residential Code for one- and two-family dwellings^6,11. The Pueblo County Building Division serves land outside the City of Pueblo and the Town of Boone; inside those jurisdictions the Southern Colorado Building Department issues building permits instead, as the City of Pueblo's code confirms for Pueblo^2,12. Septic permits stay with the Pueblo Department of Public Health and Environment either way⁵. A record owner may build a single-family dwelling or manufactured home at the owner's principal residence without a contractor license, but a county permit is still required, and a new owner-built dwelling permit is limited to once every 36 months after the certificate of occupancy¹. Structures used solely to shelter farm implements, products, livestock or poultry are exempt from the code, except for electrical and plumbing provisions⁶.

The Pueblo County Building Division handles building permits and inspection services for unincorporated Pueblo County, and the division's services began on January 1, 2026². Call 719-583-6100 or visit 201 W. 8th St. #120, Pueblo, CO 81003². The same official site is the county's online starting point for permit applications². Before applying, have the Department of Planning and Development identify the parcel's zone district, because Pueblo County publishes district-specific permitted uses and development standards^7,13. Permit fees vary: new homes and residential additions are valued by square footage, other construction uses total contract value, and every permit has a minimum fee¹⁴. We could not confirm one universal residential inspection schedule, so ask the Building Division which inspections apply. For factory-built structures, county inspections cover the foundation, utilities and installation to the foundation rather than the manufactured unit itself¹.

Yes. Pueblo County's Unified Development Code governs land use and development in unincorporated Pueblo County³. Incorporated municipalities administer their own zoning, so a parcel inside Pueblo follows the city's zoning rather than the county's^3,4. The code contains agricultural, residential, mixed-use, commercial, industrial and overlay districts, and permitted uses and dimensional standards depend on the parcel's district⁷. Pueblo County does not set a minimum size for a single-family residence, although private covenants or homeowners-association rules may do so¹⁵. Setbacks vary by district and road adjacency; in the A3 district, for example, principal buildings need 25 feet in front and 15 feet on each side and rear⁷. Lot size, coverage and building height are also district-specific⁷. Accessory dwellings are allowed only in listed districts and under additional standards: one per lot, plus an accessory farmstead dwelling in the A1 and A2 agricultural districts⁷. New manufactured homes must meet the code's manufactured-home definition, and existing mobile homes may stay on a residentially zoned lot but may not be moved and re-established⁷. Short-term rentals in unincorporated Pueblo County are limited to stays of 28 days or less and need a responsible party within 20 miles; private covenants may prohibit them⁷. Call Planning at 719-583-6000 or visit 215 W. 10th Street, Pueblo, Colorado 81003 to confirm the parcel's district¹³.

The Pueblo Department of Public Health and Environment must issue a permit before an onsite wastewater treatment system is constructed or repaired in Pueblo County, and it also issues permits to expand, use or operate a system⁵. Call 719-583-4300 or visit 101 W. 9th Street, Pueblo, CO 81003 to start with Environmental Health¹⁶. A site and soil evaluation may lead to an engineer-designed system, and the department issues a use permit after installation⁵. Colorado requires final inspection before a permitted system is used, and a building without public sewer cannot receive occupancy approval until the local health agency approves the installation¹⁷. At a sale or transfer, Pueblo County requires pumping, inspection and approval before closing¹⁸. Only about 32.4% of county soils avoid severe limitations for a conventional drain field, so make septic feasibility an early purchase contingency¹⁹.

Pueblo County allows one RV as temporary housing while a dwelling is under construction or an existing dwelling is being remodeled, but the RV requires a Temporary Use Permit and an active building permit⁷. The RV must be licensed, registered, operable and kept on private property outside the public right-of-way; occupancy is limited to six months unless the county grants an extension⁷. The application must show sewer and water connections or a plan to dispose of sewage and water at an RV dump station⁷. We could not confirm a broader rule allowing recreational camping or long-term RV residence on private land, so ask Planning before moving an RV onsite¹³. A Colorado-regulated tiny home's plans require state approval, compliance with applicable standards and local zoning, and approval tied to its installation site⁸. Pueblo County does not impose a general minimum size on a single-family residence, but that does not by itself establish where a tiny home may be occupied¹⁵.

1. Ask Planning to confirm the parcel's zone district, permitted residential use and district-specific lot, setback, coverage and height standards^7,13.
2. Resolve subdivision, legal access, drainage, soils and water before final design; all subdivisions must meet county design standards⁷.
3. Obtain an access permit from the county Department of Public Works before connecting to a county-maintained road (fees vary by road classification and use), or a Colorado Department of Transportation permit for a state or federal highway^7,20.
4. If public sewer is unavailable, obtain the public-health department's OWTS permit before construction or repair⁵.
5. Submit the building application to the Pueblo County Building Division, including an owner-builder application if eligible, and confirm the required inspection sequence^1,2,9.
6. Complete required inspections and final approvals before occupancy; an unsewered building needs final OWTS approval, and a covered structure cannot receive its certificate of occupancy until required public improvements are built and accepted^17,21.

Confirm zoning, legal access, water, septic feasibility and floodplain status before the inspection period ends. Development in a designated flood-hazard area in unincorporated Pueblo County requires floodplain review and may require scaled plans, elevations, floodproofing information and professional certifications⁷. Pueblo County averages about 13.5 inches of precipitation a year, and severe drought occurs in about 32.2% of years, so verify the parcel's lawful and dependable water source rather than treating a future well as automatic¹⁹. A new groundwater well generally requires a state permit, with statutory exemptions and basin-specific conditions¹⁰. For carrying costs, the median property-tax bill is about $1,382 a year at an effective rate near 0.5%, while the typical home-insurance premium is about $2,534 a year¹⁹. If you plan to divide the land, begin with county subdivision review; Colorado's exclusion for qualifying parcels of at least 35 acres does not replace local administration^3,22.
