Santa Cruz County, CA Property Maintenance: Weeds & Overgrown Grass (2026)

Weed and grass clearance in unincorporated Santa Cruz County is driven primarily by California state fire law rather than a unique county grass-height ordinance. Because most of the unincorporated county lies within the State Responsibility Area (SRA), California Public Resources Code Section 4291 applies: owners of parcels with an improved building must maintain 100 feet of defensible space (or to the property line). This is organized into zones. The home-defense zone, extending 30 feet from buildings, requires removing dead plants, grass, and weeds, clearing dead leaves and needles from roofs and gutters, and spacing tree canopies. The reduced-fuel zone, from 30 to 100 feet, requires mowing annual grasses to a maximum height of four inches and creating vegetation spacing. The Fire Safe Council of Santa Cruz County and local fire districts advise residents to confirm any stricter local requirements, since some areas impose increased clearance. Separate from PRC 4291, overgrown weeds, brush, and dead vegetation can be addressed by the County as a public nuisance under County Code Chapter 1.14: an enforcing officer may order abatement (generally within 10 days, or 48 hours for an immediate threat), and the County may perform the work and recover the cost on the property tax bill if the owner fails to comply. Owners doing fuel-reduction work must comply with applicable environmental laws and obtain permits where required.
