Tiny home rules in Jefferson 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.
Jeffco allows shipping containers or conex boxes as the building blocks of a home if they meet zone-district setbacks, building height, and full building-code requirements. A permanent tiny home is treated like any dwelling; a detached one used as a second residence must meet the ADU rules.
Jefferson County's Mini-Structures guide states that shipping containers or conex boxes may be used as the building blocks of a home so long as you meet the required property-line setbacks and building-height requirements of your zone district, and the structure meets building-code requirements. A tiny house on a permanent foundation is regulated as a single-family dwelling; a detached tiny home serving as a second unit falls under the ADU provisions (Section 19.D), including the owner-occupancy, lot-size, and one-ADU-per-property limits. Jefferson County does not have a stand-alone "tiny home" ordinance separate from its dwelling, ADU, and building-code standards.
Occupying a tiny home or container dwelling without a building permit and code-compliant construction is a zoning/building violation under C.R.S. 30-28-124; the County may require removal or bring it into compliance.
