Phoenix Chapter 39 (Neighborhood Preservation Ordinance) Section 39-7 requires all exterior property areas to be kept free from weeds, tumbleweeds, and grass taller than 6 inches. Dead vegetation, dead palm fronds within 10 feet of the ground, and overgrown plants that create visual blight, harbor pests, or present fire hazards must be removed. Violations are subject to civil sanctions of $100 to $2,500.
Phoenix City Code Chapter 39 classifies excessive weeds as a public nuisance and requires property owners to remove weeds and maintain lots free of overgrown vegetation. Code enforcement is complaint-driven, and the Neighborhood Services Department issues notices of violation giving property owners a specified number of days (typically 15 to 30) to clear weeds before the city arranges abatement and bills the owner. In the Sonoran Desert climate, weed growth surges during and after the monsoon season (July through September) when sudden rains stimulate rapid germination of buffelgrass, tumbleweeds, and other invasive species. Vacant lots are a particular enforcement focus, as unmanaged weed growth increases fire risk and attracts vermin. Property owners can report weedy lots through the Phoenix 311 system or contact Neighborhood Services directly at (602) 262-7844.
Specific penalty amounts for this ordinance are not published in a publicly accessible fine schedule. Contact Phoenix code enforcement directly for current fines, enforcement procedures, and hearing options.
