Riverside County, CA Property Maintenance: Vacant Lot Maintenance (2026)

Riverside County includes thousands of vacant residential and rural parcels across the Coachella Valley, Palo Verde Valley, Anza, Aguanga, and Mead Valley. Under Ordinance 695 the Fire Department inspects vacant parcels annually starting in spring; owners receive an Official Notice to Abate requiring weeds to be cut to 3 inches or less and combustible debris removed by a stated date (usually late April or May). If the owner does not comply, a county-contracted abatement crew performs the work and the cost plus an administrative fee (commonly 200 dollars or more) is added to the property tax bill as a special assessment. Ordinance 725 further prohibits accumulation of construction debris, tires, appliances, and illegal dumping; vacant lot owners who fail to fence or post against dumping may be held responsible for cleanup. Desert parcels near Joshua Tree and the Salton Sea are subject to additional Air Quality Management District fugitive dust rules (SCAQMD Rule 403) requiring stabilized surfaces during disturbance. Posted No Trespassing signs under Penal Code 602 help owners press charges for dumping and vandalism.
