As to municipal regulations in the Phoenix metro area, living in the county is generally the best option for horse owners. In Maricopa County, occupant-owned horses can be kept on any single family lot. On smaller lots (R1-35 or smaller), horses must be kept in corrals located in the rear yard, set back at least 40 feet from all lot lines, and containing at least 1,200 square feet of area per horse. For properties zoned “Rural” (RU-190, RU-70, or RU-43), there is no space requirement per horse and therefore no limit on the number of occupant-owned horses which may be kept. Up to 5 horses not owned by the owner or occupant may be boarded on a Rural-zoned lot. Next in Part 5: Horse structure Issues
