Eastvale, CA Accessory Structures: Tiny Homes (2026)

The City of Eastvale does not have a dedicated tiny-home ordinance in its Zoning Code. How a tiny home is regulated depends on its construction. A tiny home built on a permanent foundation and meeting the California Building Code (or, if factory-built, the manufactured-housing standards in Section 120.04.020) can be permitted as an accessory dwelling unit under Section 120.04.010, which means it must meet ADU size, height, and setback standards and is approved ministerially under California ADU law (Gov. Code 66310-66342). A movable tiny home on wheels (THOW) is a different matter: under California law these are typically registered and certified as recreational vehicles, and RVs are designed for recreational or temporary occupancy rather than as a permanent dwelling. Eastvale does not list a THOW as a permitted dwelling type in the residential standards reviewed, so a tiny home on wheels generally may not be occupied as a permanent residence on a single-family lot and would be limited to a lawfully operated mobile-home or RV park. The state's manufactured-housing pathway (Section 120.04.020) permits mobilehomes on permanent foundations in single-family zones subject to that zone's standards. Anyone considering a tiny home in Eastvale should confirm with the Community Development Department whether their unit is classified as an ADU, a manufactured home, or an RV, because that classification determines whether it can be a legal dwelling.
