Santa Cruz County Ordinance prohibits horses on parcels less than 3 acres and then only with a use permit and compliance with several criteria. Parcels over 4.2 acres permit horses by zoning. Living in an RV is not allowed in Rio Rico, however it can be parked on the homeowner's property in most areas of Rio Rico. (Check Santa Cruz County, AZ. Planning & Zoning) Outside Rio Rico's platted subdivision lots in the unincorporated county, rules may vary.
