Oro Valley, AZ Landscaping Rules: Grass Height Limits (2026)

The Oro Valley property maintenance code requires all lots, whether improved or vacant, to be maintained free of overgrown vegetation that constitutes a fire hazard or public nuisance. Because most Oro Valley landscaping is xeric or desert-adapted rather than traditional turf grass, the enforcement focus is on overgrown weeds, dead plant material, and accumulated vegetative debris rather than a specific mowing height. Properties must keep vegetation trimmed so it does not encroach on sidewalks, public rights-of-way, or neighboring properties. The Sonoran Desert climate produces rapid weed growth after monsoon rains (July through September), which makes seasonal enforcement particularly active. The Town Code authorizes code compliance officers to issue notices requiring cleanup within a specified timeframe, typically 15 to 30 days depending on the severity. Vacant lot owners are held to the same maintenance standards as improved properties. Pima County also has nuisance vegetation provisions that may apply in unincorporated areas adjacent to town boundaries.
