Maricopa County Ordinance P-11 (Abatement Ordinance) requires property owners to maintain lots free of weeds, overgrown vegetation, and fire hazards. While the county does not specify a precise grass height limit like many cities, properties with excessive weed or grass growth that creates a nuisance, fire hazard, or harbors pests may be subject to abatement action by Code Compliance.
Maricopa County Ordinance P-11 (Abatement of Nuisances and Hazardous Conditions) authorizes Code Compliance to address overgrown vegetation on properties in unincorporated areas. While the ordinance does not specify a maximum grass or weed height in inches, properties where vegetation growth creates a fire hazard, harbors vermin, or constitutes a public nuisance are subject to abatement action. Code Compliance issues a notice to the property owner allowing a compliance period before the county may abate the condition and bill the owner for costs. Given the desert climate, weed growth is most problematic after monsoon season (July-September) when rapid growth of buffelgrass and other invasive species occurs. Report overgrown lots to Maricopa County Code Compliance at (602) 506-3301.
