Tempe's Building Setbacks & Zoning: The Rules That Matter

Every city handles building setbacks & zoning a little differently. In Tempe, Arizona, there are 3 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Setback Rules

Tempe's Zoning and Development Code establishes minimum setback requirements that vary by zoning district. Single-family residential zones typically require 20-25 foot front setbacks, 5-10 foot side setbacks, and 15-25 foot rear setbacks. Accessory structures may have reduced setback requirements. Corner lots have additional requirements for street-side setbacks.

Key details: Governing Code: Tempe Zoning and Development Code. Front Setback: Typically 20-25 ft in R-1 zones. Side Setback: Typically 5-10 ft interior side. Rear Setback: Typically 15-25 ft. Small Structures: Under 200 sq ft / 8 ft may have reduced setbacks.

Buildings constructed within required setbacks without a variance face code enforcement action, including orders to remove the encroaching portion.

Structure Height Limits

Tempe's Zoning and Development Code establishes maximum building height limits by zoning district. Single-family residential zones typically allow structures up to 25-30 feet in height. Multi-family and commercial zones allow taller buildings. Height is generally measured from finished grade to the highest point of the roof. Accessory structures are limited to 8 feet unless classified as accessory buildings.

Key details: Single-Family: Typically 25-30 ft maximum. Measurement: From finished grade to highest roof point. Accessory Structures: 8 ft maximum before becoming accessory building. Downtown: Specific height overlay districts allow taller buildings. Exceptions: Chimneys, antennas, mechanical equipment may exceed.

Structures exceeding height limits without a variance face code enforcement action, potentially including removal of the non-conforming portion.

Lot Coverage Limits

Tempe's Zoning and Development Code establishes maximum lot coverage limits that vary by zoning district. Lot coverage includes the footprint of all structures (main dwelling, accessory buildings, carports, patios with solid roofs). In single-family residential districts, typical maximum lot coverage ranges from 35-45% depending on the specific zone. Accessory structures and ADUs count toward lot coverage calculations.

Key details: Governing Code: Tempe Zoning and Development Code. Single-Family: Typically 35-45% maximum lot coverage. Included: All structures with roofs: dwelling, garage, carport, patio covers. Excluded: Swimming pools generally not counted. ADUs: Count toward lot coverage.

Exceeding maximum lot coverage without a variance may result in denial of building permits and orders to reduce building footprint.

The Bottom Line

Tempe's building setbacks & zoning rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Tempe is broadly strict or permissive.

Keep in mind that Tempe can amend these rules at any council meeting. For the most current version of any rule mentioned here, check the specific ordinance page, where we track updates as they happen.
