Chino, CA
San Bernardino County
Chino enforces overgrown grass and weeds through Title 8 (Health and Safety) nuisance abatement, mirroring California's statewide weed abatement framework. Cal. Health & Safety Code section 14875 defines weeds to include 'weeds that bear seeds of a downy or wingy nature' and 'dry grass, stubble, brush, litter, or other flammable material which endangers the public safety by creating a fire hazard.' There is no specific blade-height number, but tall dry vegetation that creates a fire menace to adjacent improved property is abatable.

San Bernardino County
Hesperia contracts with San Bernardino County Fire Hazard Abatement to enforce defensible space. Weeds and grasses must be cut to no more than 4 inches in height within 30 feet of any structure. The High Desert/Mojave WUI environment makes overgrown vegetation a year-round fire hazard, especially tumbleweeds in the fall.

Chino FAQ
How tall can my grass be in Chino before I get a notice?
Chino does not publish a numeric inch limit. Code Compliance evaluates whether vegetation is overgrown to the point of being a nuisance or fire hazard. Standard residential lawns kept under roughly 6 to 8 inches and free of weed seedheads generally avoid complaints; tall dry vegetation does not.
Does the rule apply to vacant lots and the Chino Dairy Preserve?
Title 8 nuisance abatement applies citywide. Active agricultural and equestrian operations in the Agricultural Preserve overlay are treated as the permitted land use, but unkempt vegetation visible from public rights-of-way is still abatable under the state weed-nuisance statute.
Hesperia FAQ

Weeds and grasses must be cut to no more than 4 inches in height within 30 feet of any structure. State law (PRC §4291) also requires 100 feet of defensible space around structures in fire hazard zones.
