From the Colorado guide

Can you live in an RV or tiny home on your land in Colorado?

Colorado has county-specific RV answers for 24 counties: 9 allow temporary occupancy only, 13 have limited allowances and 2 prohibit occupancy; the other 40 counties remain unanswered.7 Temporary-only examples include Teller County, Garfield County and Montrose County.7 An unanswered county is neither permission nor a prohibition; ask the parcel’s county planning office about residential RV occupancy before buying.7

Colorado has tiny-home answers for 23 counties: 5 allowed with applicable conditions and 18 limited, with 41 counties unanswered.12 The allowed category includes Routt County, Gunnison County, El Paso County, Larimer County and Boulder County; use the tiny-home county list to compare the conditions.12 Colorado Division of Housing-regulated residential tiny homes are approved for long-term living, subject to approved plans, applicable standards and local zoning.13 DOH certifies tiny-home units for their specific installation site, so ask DOH about a proposed relocation before moving a unit.32 HUD-code manufactured homes can be installed anywhere in Colorado only where local zoning allows it; the Division of Housing regulates installation and installation inspections, while local building departments regulate mobile-home foundations.18

A second dwelling is a separate question. Colorado requires one accessory dwelling unit, approved administratively, beside a single-unit detached house in larger municipalities and in county areas inside census-designated places of at least 40,000 people within a metropolitan planning organization.33 That rule does not cover every town or rural county, so ask the parcel’s planning office.33
