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

Section 21-420(A)'s property development standards table lists a flat 30-foot maximum building height across all eight single-family zoning districts, R1-43, R1-35, R1-18, R1-12, R1-10, R1-8, R1-7, and R1-6, so unlike lot coverage and setbacks, height does not scale with lot size. Section 21-421(A) carries the same ceiling into conditionally permitted principal buildings, stating the maximum is 'two stories of not more than thirty (30) feet, except as provided in Section 21-304 of this Ordinance,' which covers the City's administrative height-exception process for specific site conditions.

Separately, Section 21-419(A) caps any structure within a lot's required front setback area at just 3 feet above grade, preventing a tall wall, fence, or accessory feature from blocking sightlines near the street even though the home itself can reach the full 30 feet farther back on the lot. Accessory buildings are held to a lower 15-foot maximum under Section 21-436(A) when located in mobile home subdivision (RMH-1) settings, keeping detached garages, sheds, and casitas well below the two-story principal-structure limit. Builders proposing anything taller than 30 feet on a single-family lot, a tower element, elevator overrun, or widow's walk, need a variance from the Board of Adjustment rather than a routine building permit.
