Unincorporated Pueblo County, Colorado requires building permits, which the Pueblo County Building Division issues outside the City of Pueblo and the Town of Boone12. Zoning in unincorporated areas comes from the county's Unified Development Code, while Pueblo and other incorporated places run their own zoning34. Septic permits for the whole county, city or not, come from the Pueblo Department of Public Health and Environment5.

Do you need a building permit in Pueblo County, Colorado?
Yes. Unincorporated Pueblo County requires permits for excavation, grading, fill and construction, including work performed by an owner14. 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 dwellings156. 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 Pueblo216. Septic permits stay with the Pueblo Department of Public Health and Environment either way17. 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 occupancy1819. Structures used solely to shelter farm implements, products, livestock or poultry are exempt from the code, except for electrical and plumbing provisions20.
Who handles Pueblo County building permits, and how do you reach them?
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 standards2122. 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 fee23. 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 itself24.
Does Pueblo County, Colorado have zoning?
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's254. The code contains agricultural, residential, mixed-use, commercial, industrial and overlay districts, and permitted uses and dimensional standards depend on the parcel's district21. Pueblo County does not set a minimum size for a single-family residence, although private covenants or homeowners-association rules may do so26. 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 rear27. Lot size, coverage and building height are also district-specific282930. 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 districts31. 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-established32. 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 them33. Call Planning at 719-583-6000 or visit 215 W. 10th Street, Pueblo, Colorado 81003 to confirm the parcel's district22.
How do septic permits work in Pueblo County?
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 system175. Call 719-583-4300 or visit 101 W. 9th Street, Pueblo, CO 81003 to start with Environmental Health34. A site and soil evaluation may lead to an engineer-designed system, and the department issues a use permit after installation9. 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 installation3536. At a sale or transfer, Pueblo County requires pumping, inspection and approval before closing37. Only about 32.4% of county soils avoid severe limitations for a conventional drain field, so make septic feasibility an early purchase contingency38.
Can you live in an RV or tiny home in Pueblo County?
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 permit10. 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 extension39. The application must show sewer and water connections or a plan to dispose of sewage and water at an RV dump station4041. 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 onsite22. A Colorado-regulated tiny home's plans require state approval, compliance with applicable standards and local zoning, and approval tied to its installation site11. 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 occupied26.
What are the steps to build a home in Pueblo County?
- Ask Planning to confirm the parcel's zone district, permitted residential use and district-specific lot, setback, coverage and height standards212722.
- Resolve subdivision, legal access, drainage, soils and water before final design; all subdivisions must meet county design standards42.
- 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 highway4344.
- If public sewer is unavailable, obtain the public-health department's OWTS permit before construction or repair45.
- Submit the building application to the Pueblo County Building Division, including an owner-builder application if eligible, and confirm the required inspection sequence14122.
- 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 accepted353646.
What should you check before buying land in Pueblo County?
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 certifications47. 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 automatic4849. A new groundwater well generally requires a state permit, with statutory exemptions and basin-specific conditions13. 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 year505152. 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 administration5354.
Watch-outs
- Do not use City of Pueblo or Town of Boone permit instructions for an unincorporated parcel; the Pueblo County Building Division is the correct building office outside those jurisdictions2.
- Pueblo County requires septic inspection and approval before closing when property with an OWTS is sold or transferred37.
- A designated flood-hazard parcel may require a Floodplain Development Permit and additional technical documentation before development47.
- An RV temporary-housing permit does not create a general right to camp or live indefinitely on private land; ask Planning about any use outside active construction or remodeling1022.

- Share of soils USDA rates "not limited" for a conventional septic drain field (SSURGO). A strict rating: the median county is about 6% and a tenth of counties are 0%, so a low figure means most lots need a site evaluation or an engineered system, not that septic is impossible.
