Phoenix City Code Chapter 39, Section 39-7 limits lawn grass height to 6 inches. Properties must be kept free from overgrown grass that presents visual blight, harbors insects or rodents, or creates fire hazards. This does not apply to single-residence rear yards not visible from the adjacent right-of-way. Code Compliance investigates complaints.
Phoenix City Code Chapter 39 (Property Maintenance) requires property owners to maintain vegetation in a manner that does not create a nuisance, fire hazard, or harbor vermin, though there is no specific maximum grass height stated in inches. Overgrown yards with grass, weeds, or unmaintained vegetation exceeding approximately 6 to 10 inches are typically cited as a nuisance violation through the city's complaint-driven code enforcement process. Given Phoenix's desert climate with summer temperatures exceeding 110°F, many residential properties use desert landscaping with gravel and native plants rather than traditional grass lawns, reducing grass-height concerns. Properties with neglected landscaping receive a notice of violation from the Neighborhood Services Department with a compliance period, after which the city may abate the property and charge the owner. File landscape maintenance complaints with Phoenix Neighborhood Services at (602) 262-7844.
