Weed Ordinances: Simi Valley vs Thousand Oaks

When is weed abatement required in Simi Valley?

The annual weed abatement program runs in spring with compliance deadlines typically in May or June. Weeds within 10 feet of structures must be controlled year-round.

What happens if I do not clear weeds on my property?

After notice, the city will hire contractors to clear the property and bill you for the cost plus a 25% administrative fee. A lien may be placed on the property for unpaid costs.

Does weed abatement apply to occupied properties?

Yes, all properties must maintain weeds and vegetation. Occupied residential lots must keep weeds under 12 inches and maintain clear areas around structures for fire safety.

When must I clear weeds in Thousand Oaks?

Annual weed abatement notices require compliance by early June. Properties in fire zones must maintain year-round defensible space. Given Thousand Oaks' fire history including the 2018 Woolsey Fire, vegetation management is taken very seriously.

How much defensible space do I need?

100 feet from structures. The first 30 feet should be a lean, clean zone with minimal combustible vegetation. From 30-100 feet, thin vegetation and remove dead material. Properties adjacent to open space have the highest priority.

Who inspects properties for weed compliance?

The Ventura County Fire Protection District conducts annual inspections as part of the weed abatement program. Properties adjacent to open space and in hillside areas receive priority inspection. Contact Fire Prevention at (805) 389-9710.
