Phoenix Zoning Ordinance Section 701 sets height limits by district. Most single-family residential districts (R1-6 through R1-10) have a 30-foot maximum. Multi-family and commercial zones allow greater heights. Development adjacent to lower height zones must provide step-backs, with setbacks increased by 10 feet for portions exceeding the adjacent zone's limit.
Phoenix regulates maximum building and structure heights through the zoning code. Typical residential zones allow 35 feet or 2.5 stories, whichever is less. Height is measured from average finished grade to the highest point of the roof. Chimneys, antennas, and mechanical equipment may be exempt up to a limited additional height. Commercial and mixed-use zones may allow greater heights. Planned unit developments may negotiate alternative height standards. Height variances require zoning board review.
Exceeding height limit: stop-work order. Required to reduce height or obtain variance. Fines $250 to $2,000.
