Unincorporated Glenn County does set a numeric vegetation-height standard. Its nuisance code makes premises with 'weeds over three inches tall' a public nuisance when they harm the public or create blight, and the Weed Control chapter (7.28) treats weeds over three inches tall as a violation. Overgrown grass/weeds can be ordered abated at the owner's cost.
Glenn County's property-maintenance nuisance rules live in Glenn County Code Chapter 1.15 (Public Nuisance Abatement). Section 1.15.022 (Specific Property Nuisance) declares it unlawful to allow premises where 'overgrown, dead or decayed trees, weeds over three inches tall, or other vegetation pose a risk of harm to the public, or constitute visual blight or reduce the aesthetic appearance of the neighborhood,' when visible from the public right-of-way. The separate Weed Control chapter (Chapter 7.28), amended by Ordinance 1334 on March 25, 2025, similarly makes it 'unlawful and a public nuisance' to allow premises to have 'weeds over three inches tall, or other noxious vegetation, refuse, or rubbish' that pose a risk of harm (Section 7.28.040). Chapter 7.28 is adopted under California Health & Safety Code sections 14930-14931, which let the county compel owners to cut and remove hazardous weeds and vegetation. Enforcement is complaint- and inspection-driven: an enforcing officer in Planning & Community Development mails or posts an abatement notice giving a deadline to cut the vegetation; if the owner does not comply, the county may enter and abate the property and place the cost as a lien (Sections 7.28.080, 7.28.140, 7.28.150). The county's own weed-abatement service contracts describe cutting vegetation to roughly four inches at the ground.
Failure to abate after notice lets the county cut the vegetation and recover the cost as a lien or special assessment against the property; nuisance violations are also enforceable by administrative citation, civil action, and the penalties in Chapter 1.15.
