Berkeley FAQ
What if I want a no-mow native meadow?
Berkeley allows native bunchgrass landscapes if submitted as a fire-wise plan to the Vegetation Management Unit. Plants must be spaced and irrigated to prevent continuous fuel load.
Does this apply to vacant lots I own?
Yes. Vacant parcels are inspected and abated identically to occupied homes. Absentee owners are billed at the same rates and can face liens.
Fremont FAQ
Do ornamental grasses count?
Maintained ornamental and native grasses used as intentional landscape are generally exempt. The rule targets dry weeds and invasive annual grasses like wild oats and ripgut brome that become fuel when cured brown.
Who do I call to report a weedy vacant lot?
Call Fremont Fire Prevention at 510-494-4200 or use the Fremont 311 app. Include the parcel address and, if possible, the APN. Inspectors respond within 10 business days during abatement season.
