Fremont, CA Landscaping Rules: Weed Ordinances (2026)

Section 8.25.010 defines the 'weeds' this duty covers in five categories: weeds bearing downy or wingy seeds; sagebrush, chaparral, indigenous grasses or other brush that could become a fire hazard as the enforcement officer determines; weeds otherwise noxious or dangerous; poison oak and poison ivy grown to the point of threatening public health; and accumulations of dry grass, stubble, brush, litter, garden refuse and other combustible trash that create a fire hazard. The duty in Section 8.25.030 falls on the property owner, an agent, a lessee, or anyone else occupying or controlling a parcel, and it reaches homeowners' associations and property management companies that control a common interest development's common areas, per the definitions in Section 8.25.010.

Fremont enforces this duty as it does any other neighborhood-preservation nuisance: Section 8.25.040 routes enforcement through Chapter 8.60, meaning the city manager, as enforcement officer, can inspect, issue a notice for specific abatement, and if the owner does not clear the weeds, have the city perform the abatement and bill the cost, or issue an administrative citation under Chapter 1.20 with civil penalties of up to $100 for a first offense, $200 for a second citation for the same violation within a year, and $500 for a third or later citation within a year. Fremont's ordinance does not set a numeric maximum height for grass or weeds; the standard is whether the growth constitutes a 'nuisance' under Section 8.25.010's definition, based on fire-hazard potential, noxiousness, or offensiveness to neighboring residents, leaving the enforcement officer to make that call on inspection.
