Avondale limits building height by zoning district. Most single-family and lower-density multi-family residential districts cap principal buildings at 30 feet, while higher-density districts such as R-4 allow up to 45 feet. Accessory buildings are limited to 15 feet.
Building height in Avondale is set by the residential dimensional standards in Chapter 28, Article 2. Single-family districts including R1-6, R1-8, and R1-10 each have a maximum building height of 30 feet, as do the R-2 and R-3 multi-family districts. The higher-density R-4 district allows a maximum height of about 45 feet, with the potential for greater height under specific area plans. For accessory structures, Section 28-133 limits residential accessory buildings to a height no greater than 15 feet. Article 7 also provides height exceptions in Section 28-134: certain religious structures and architectural features may extend above the roof, mechanical equipment may rise up to 15 feet above the building height limit, and parapet walls may extend a maximum of 5 feet above the limit. Height is measured according to the definitions in the zoning code. Because the maximum height depends on the parcel's zoning district and any planned-area-development overlay, builders should confirm the controlling height for their lot with Avondale Development Services, particularly for two-story homes, rooftop equipment, or any structure near the district maximum.
Exceeding the district height limit, or building an accessory structure taller than 15 feet, violates Article 2 and Section 28-133. Permits can be denied or revoked, and a structure built over the allowed height may need to be modified to comply. Height-exception features must stay within the limits in Section 28-134.
