Chino FAQ
Do I need to maintain my vacant lot in unincorporated San Bernardino County?
Yes. Owners must keep lots free of weeds, debris, and fire hazards. In high-fire-severity zones (most mountain and WUI areas), annual weed abatement and 100-foot defensible space are required.
What is defensible space?
Under California Public Resources Code 4291, property owners must maintain 100 feet of reduced-vegetation defensible space around structures. The first 30 feet must be lean, clean, and green.
San Bernardino FAQ
When is the weed abatement deadline in San Bernardino?
Typically late May, set each year by City Council resolution. Owners receive written notice by mail approximately 30 to 60 days in advance.
What if my lot is a chronic illegal dumping target?
Installing a fence, cameras, no-trespassing signs, and lighting can reduce incidents. The city will still cite the owner if dumping accumulates, but good faith security measures are considered in penalty decisions.
Can the city really put a lien on my lot for weeds?
Yes. Under Government Code 39580 through 39588 and Municipal Code Chapter 8.27, unpaid abatement costs are placed on the property tax roll as a special assessment collected like taxes.
