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.
