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

Unincorporated Mono County does not, in the sources reviewed, publish a numeric weed or grass height limit (such as a 6- or 12-inch maximum) for general property maintenance. Instead, overgrown vegetation, weeds, and associated rubbish are handled as potential public nuisances. Under General Plan Chapter 49 (Enforcement), the Community Development director responds to complaints about property maintenance affecting health, issues a Notice of Violation, and orders correction or abatement within 30 days. If the owner does not comply, the County may refer the matter to the District Attorney, request the Board of Supervisors abate the nuisance under Chapter 7.20 of the County Code, or issue an administrative citation under Section 1.12. Because exact code text from Chapter 7.20 could not be retrieved from the codifier during this research, no specific weed-height number, deadline date, or per-day penalty is asserted here. Separately, much of Mono County is high-fire-hazard terrain, and clearing dry grass, weeds, and brush around structures is governed by California defensible-space requirements (Public Resources Code Section 4291) and local fire-safe rules enforced by fire agencies, which operate independently of the general nuisance process. Property owners concerned about a neighbor's overgrowth should file a code-compliance complaint, while those clearing for fire safety should consult the applicable fire district.
