Plumas County, CA Landscaping Rules: Weed Ordinances (2026)

Weed and dry-vegetation control in unincorporated Plumas County is driven by wildfire risk. Because the entire unincorporated county lies within a State Responsibility Area, the central rule is California Public Resources Code Section 4291, which requires owners of buildings or structures on or adjoining grass-, brush-, or forest-covered land to maintain 100 feet of defensible space and to keep flammable fuels (which PRC 4291 expressly defines to include grasses and weeds) cleared and properly spaced so a wildfire is unlikely to ignite the structure. Defensible space is inspected by CAL FIRE and local fire protection districts (for example, Quincy Fire Protection District performs PRC 4291/AB 38 inspections). Plumas County Code Enforcement investigates violations of the County Code and California Health and Safety Code and works to prevent blight, and the county's code includes a Weeds chapter (Title 5) and general nuisance authority. In practice, much front-line weed-and-debris abatement is handled at the community level: in 2018 the Indian Valley Community Services District sent letters citing Greenville-area properties with at least knee-high weeds and flammable debris, gave owners about 30 days to comply, and warned that tax liens could follow non-compliance. Because exact thresholds and procedures vary by district, owners should confirm requirements with their local fire protection or community services district.
