Tiny home rules in Maricopa, AZ — 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.
Maricopa generally allows only one dwelling unit per lot and regulates manufactured homes and recreational vehicles under MCC 18.120.150. RVs and park-model trailers used as dwellings are limited to recreational vehicle parks, resorts, and subdivisions, with one RV per approved space. A standalone tiny home cannot become a second independent dwelling on a standard residential lot, and casita-style units are treated as non-rentable guest quarters.
Maricopa does not have a dedicated 'tiny home' category; how a small dwelling is treated depends on whether it is a permanent foundation structure, a manufactured home, or a recreational vehicle. Under MCC 18.120.150, one manufactured home, mobile home, or modular home is permitted per approved space only in residential manufactured home parks and subdivisions, and one recreational vehicle or park-model home trailer is permitted per approved lot or space only in RV parks, resorts, and subdivisions. The aggregate enclosed floor area of all RV accessory structures is limited to 520 square feet. Temporary parking of an RV or park model on a public street in a residential area for loading, unloading, or cleaning is allowed for up to 48 hours. Critically, no more than one dwelling unit is allowed per lot under the city code except in the Heritage Mixed-Use Overlay District, so a tiny home cannot be added as a second residence on a typical lot. A small accessory structure that includes living and cooking space would have to qualify as guest quarters (which cannot be rented). Anyone planning a tiny home should confirm foundation, building code, zoning district, and dwelling-unit limits with Development Services before proceeding.
Living in a tiny home, RV, or park model on a standard residential lot outside an approved park or subdivision, or creating a second dwelling unit on a lot limited to one, can result in code-enforcement citations, fines, and orders to vacate or remove the structure. Unpermitted permanent structures must be brought up to code or removed.
