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

Section 28-35's development standards tables set a flat 30-foot maximum building height across all ten single-family zoning districts, AG, RR-43, R1-35, RR-18, R1-15, R1-10, R1-8, R1-7, R1-6, and R1-5. In the multi-family tables, R-2 and R-3 stay at 30 feet as well, but the R-4 district is allowed up to 45 feet under a footnote that lets that cap be exceeded only where land is identified by an adopted specific area plan, such as the Freeway Corridor Specific Plan or the North Avondale Specific Plan, as appropriate for additional height, in which case the plan's own height figure controls instead of the 45-foot default.

Section 28-134 layers exceptions onto every district's height limit: attached church spires, crosses, belfries, cupolas, flagpoles, clock towers, and domes may rise above the roof no more than the height of the building itself, while detached versions of those features can go up to twice the height of the tallest building on site. Chimneys, bulkheads, non-occupied penthouses, ventilators, skylights, water tanks, and similar mechanical equipment are limited to 15 feet above the building height limit and must be fully screened or architecturally integrated. Parapet walls or cornices may extend up to 5 feet above the height limit, measured from the highest side of a sloped roof.

Detached accessory buildings on residential lots are separately capped at 15 feet under Section 28-133(e), except for ADUs governed by Section 28-33 and certain AG-district agricultural structures.
