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

Unincorporated Mono County addresses vacant and undeveloped lots primarily through its general nuisance framework rather than a stand-alone vacant-property ordinance. Under General Plan Chapter 49 (Enforcement), the Community Development director acts on a complaint basis when property maintenance creates health or nuisance concerns, issuing a Notice of Violation that requires correction or abatement within 30 days. Conditions on vacant lots such as accumulated rubbish, junk, abandoned materials, or hazards can be pursued as a public nuisance: the director may refer the matter to the District Attorney, request the Board of Supervisors initiate abatement under Chapter 7.20 of the County Code, or issue an administrative citation under Section 1.12. The specific text of Chapter 7.20 was not retrievable from the codifier during this research, so exact dimensional standards (for example, a required clearance distance or weed height) for vacant lots are not asserted here. Property owners in Mono County also have wildfire-related vegetation responsibilities that are administered separately through fire-safe and defensible-space requirements; those are distinct from the general nuisance process and are not detailed here. Owners of vacant parcels should keep them free of rubbish and junk and respond promptly to any Notice of Violation to avoid abatement costs being assessed against the property.
