Colorado Tiny Home Rules by County

Saguache County says it is not zoned but does require building permits. Its FAQ lists a minimum residence size of 150 square feet for one person plus 100 square feet for each additional household member, making it a strong tiny-home research candidate when permitting and septic requirements can be met.

Alamosa County is one of the better tiny-home research candidates, but it should be treated as code-dependent. County materials say residential uses are allowed in most zoned districts except Commercial and Industrial, and the county has separate camping, campground, RV, and tiny-home-related land-use materials; tiny homes on trailers/RV-like frames should be reviewed differently than code-compliant dwelling units.

Chaffee County is a stronger tiny-home research county than many mountain counties because the Land Use Code includes tiny-home standards. Even so, tiny homes need review under zoning, building permit signoff, roads, floodplain, OWTS/septic, water, and whether the unit is a permanent dwelling or RV-like unit.

Costilla County requires land use permits and tells buyers to review the Land Use Code before purchasing property, starting construction, or changing/improving land. Tiny homes remain a strong research candidate because county resources include construction, manufactured home, occupancy inspection, OWTS, physical address, road access, and building-code materials, but parcel classification and dwelling standards must be confirmed before purchase.

Delta County is a stronger tiny-home research candidate than many counties because its Land Use Code and county FAQ discuss dwelling units broadly and distinguish permanent utility-connected dwellings from temporary recreational vehicle use. Any tiny home still needs zoning, building, utility, water, wastewater, and access review.

Archuleta County should be scored as land-use-regulation dependent for tiny homes. Land Use Regulations and residential building permit materials are available, and any tiny home needs review for zoning, building and zoning compliance, foundation/dwelling classification, water, septic, access, wildfire, and Pagosa-area/subdivision rules.

Baca County is a very rural affordability and off-grid research candidate, but public online land-use detail is limited. Treat tiny homes as direct-county-review projects requiring confirmation of zoning/land-use status, dwelling classification, building permits, foundation/manufactured-home path, water, septic/OWTS, and legal access.

Bent County should be scored as permit-dependent rather than broadly tiny-home friendly. The Land Use Office page lists the Planning and Zoning Manual, building permit application, and new manufactured home placement application, but no tiny-home-specific allowance was found in the public page.

Cheyenne County is an affordability and low-density research candidate, but tiny homes should be scored as permit-dependent. The zoning ordinance defines single-family dwellings, modular homes, mobile homes, and dwelling units, but no tiny-home-specific allowance was found.

Conejos County is a solid rural research candidate, but tiny homes should be scored as permit-dependent rather than broadly allowed. The Land Use Office administers building permits and has adopted 2018 ICC building codes; the Land Use Code defines single-family dwellings to exclude tents, camper trailers, and other structures designed or used primarily for temporary occupancy, while allowing properly permitted mobile or manufactured homes.
