Tiny home rules in Perris, CA — 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.
Perris has no separate 'tiny home' ordinance. A tiny house on a permanent foundation is generally permitted as an accessory dwelling unit under Municipal Code Chapter 19.81 (minimum 320 sq ft). A tiny house on wheels is treated as a recreational vehicle and may not be used as a permanent residence on a standard residential lot.
The Perris Municipal Code does not contain a dedicated tiny-home chapter. In practice, a tiny house built on a permanent foundation is reviewed as an accessory dwelling unit under Chapter 19.81 (Ordinance No. 1449, 2025). That chapter sets a minimum unit size of 320 square feet but states this shall not prohibit construction of an efficiency unit pursuant to Government Code Section 66321 (Secs. 19.81.070-19.81.100). An ADU also includes a manufactured home as defined in California Health and Safety Code Section 18007 (Sec. 19.81.020), so a factory-built tiny home on a foundation can qualify if it meets the chapter's height, setback, and parking standards and a kitchen and sanitation are provided. A movable tiny house on wheels (THOW) is generally classified as a recreational vehicle or trailer rather than a dwelling; the code's recreational-vehicle provisions and Chapter 19.58 (Recreational Vehicle Parks) do not authorize using an RV or trailer as a permanent residence on an ordinary single-family lot. There is no specific Perris ordinance permitting tiny houses on wheels as permanent dwellings, so anyone considering one should confirm the route with the Development Services Department. The most reliable path to a legal small dwelling in Perris is the ADU/JADU process under Chapter 19.81.
Living in a tiny house on wheels, RV, or trailer as a permanent residence on a residential lot, or installing a tiny home without ADU permits, can trigger code enforcement and orders to cease occupancy or remove the structure.
