Maricopa, AZ Building Setbacks & Zoning: Structure Height Limits (2026)

Structure height in the City of Maricopa is regulated by zoning district under MCC Title 18, with the maximum building height for each district set in that district's development standards table (for example, Table 18.35.030 for RS single-family districts and 18.35.040 for RM, RH, and RMHP). A transitional rule limits the maximum height within 30 feet of an RS district to 30 feet, protecting single-family neighborhoods from taller adjacent buildings. For detached residential accessory buildings, the City of Maricopa Residential Accessory Structures Guide states a maximum height of fifteen (15) feet, while guest quarters above a garage may reach 25 feet with a pitched roof, subject to MCC 18.120.010 guest-quarter standards. Under MCC 18.80.080, certain structures listed in Table 18.80.080, such as chimneys and similar rooftop appurtenances, may exceed the maximum permitted building height subject to limits in that table, but no portion above the height limit may be used for sleeping quarters or advertising. How height is measured matters: for lots in a platted subdivision, height is generally measured from the finished grade shown on the grading plan (or the individual lot grading plan, whichever is lower) to the highest point. Because most Maricopa lots are in HOA-governed subdivisions, association rules and the approved grading plan may further constrain effective height. Confirm the specific district maximum and measurement basis before designing.
