The Short Version
Phoenix doesn't have a traditional grass height ordinance since most yards are desert landscaping. Instead, the city focuses on weed abatement and lot maintenance. Weeds and vegetation can't exceed 6 inches in height on any residential property. Dead vegetation must be removed because of fire risk — this is Arizona, and dry brush is a real hazard. The Neighborhood Services Department handles complaints, and Phoenix is aggressive about enforcement on vacant lots. The city can mow your lot and bill you if you don't respond to a notice, and the bill comes with a $400+ administrative fee.
Full Breakdown
Phoenix's property maintenance standards (City Code Chapter 39, Article II) focus on fire prevention and pest control rather than the traditional Midwest/East Coast "mow your lawn" rules. In a desert city, the main concerns are dry weeds that can fuel fires and overgrown vegetation that harbors scorpions, rats, and other pests.
The 6-inch height limit applies to all weeds and grass, including in rock-landscaped yards where weeds grow between stones. Property owners are also required to remove dead palm fronds, fallen branches, and accumulated plant debris. The fire department has weighed in on these rules — dry palm fronds are a significant fire risk.
Phoenix runs proactive sweeps of vacant and neglected lots, especially before summer fire season. If you get a notice, you have 30 days to clear the property. After that, the city sends a contractor, does the work, and bills you — typically $200-$800 for the work plus a $400+ administrative surcharge. That charge becomes a lien on your property if unpaid.
What Happens If You Violate This?
First notice gives 30 days to comply. If the city abates, you pay the contractor's fee plus a minimum $400 administrative charge. Repeated violations within 12 months can result in expedited enforcement with only 10 days' notice. Unpaid abatement costs become property liens.
