Tiny home rules in Douglas County, CO — covering tiny houses on wheels (THOWs), park model RVs, and tiny home on foundation builds — determine where they are legal and how they get permitted.
Douglas County has no tiny-home-specific ordinance. A tiny house on a permanent foundation must meet the 2021 building code and zoning like any dwelling. A tiny house on wheels is treated as an RV or mobile home and cannot be a permanent residence outside the MH district.
A stick-built or modular tiny house on a permanent foundation is regulated as a single-family dwelling: it needs a building permit, must meet the 2021 IRC, and must satisfy district setbacks and minimum lot sizes. A tiny house on wheels is legally an RV and is not a permitted permanent dwelling in residential zones. Under Section 302.10, the A-1 district allows a mobile home only as a caretaker residence when a principal single-family dwelling already exists; converted mobile homes are otherwise limited to the MH zone district. Incorporated towns set their own rules.
Occupying an RV or tiny house on wheels as a permanent residence, or building without a permit, is a zoning violation subject to enforcement and abatement.
