Hayward FAQ
Does this apply to ornamental grasses?
Live, irrigated ornamental plantings are generally allowed; the rule targets dry, flammable weeds and grass.
What if my property is vacant?
Vacant parcels are still subject to abatement and frequently top the enforcement list.
Oakland FAQ
Is there a specific lawn height limit in Oakland?
There is no single citywide maximum. Hillside properties follow defensible space rules requiring grass under 3 inches near structures, while flatland properties are judged case by case under the public nuisance ordinance.
What if I miss the Vegetation Management deadline?
The Oakland Fire Department issues a reinspection notice with fees, and if still noncompliant, contracts the work and bills the owner plus administrative costs as a property lien.
