How do grass height limits rules compare between Chino, CA and San Bernardino, CA?
Chino and San Bernardino have similar restriction levels.
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.

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.
San Bernardino FAQ
How tall can my grass legally be in San Bernardino?
There is no single inch threshold citywide, but front-yard grass over roughly 6 in. draws nuisance citations, and foothill parcels must be cut to 4 in. in fire season.
What if I cannot mow my property on time?
Contact San Bernardino Code Enforcement or the county Hazard Abatement program before the deadline; extensions are rare but possible for documented hardship.
Can the county mow my property and bill me?
Yes. If you miss the abatement deadline, the county contracts the work and adds it to your property tax bill as a lien or special assessment.
