Full Breakdown
Weld County Code Chapter 23 does not have a dedicated tiny-home category, so a tiny home is regulated by how it is built. Section 23-3-20 allows one single-family dwelling or group home per legal lot in the Agricultural zone; a permanent, site-built tiny house on a foundation is that dwelling and must meet building code, or it can be your one allowed ADU under Section 23-4-600. A tiny house on wheels is a recreational vehicle under Division 3 (Manufactured Homes, Manufactured Structures, and Occupied Recreational Vehicles) and generally may not be occupied as a permanent home on a residential lot. Cities of Greeley and Evans set separate rules. Confirm classification with Weld County Planning Services first.
Violations & Fines
Placing a second dwelling beyond the one allowed, or living permanently in an RV or tiny house on wheels outside code, is a zoning violation enforced by Weld County Code Compliance under Chapter 23, Article X.
