Livermore FAQ
Does defensible space apply to my Livermore home?
Only if your property is mapped in the VHFHSZ — primarily hillside neighborhoods on the south and east sides. Check CAL FIRE's FHSZ viewer for your parcel.
When does LPFD inspect for weed abatement?
LPFD mails notices in spring (typically April-May) with 30-day compliance windows before city-contracted abatement at owner cost.
Sunol FAQ
When do inspections occur?
The Alameda County Fire Department and CAL FIRE typically inspect from May through October, with peak focus in June and July before peak fire season.
What happens if I fail inspection?
You receive a notice to correct with a deadline; failure to correct results in fines and county abatement where contractors perform the work and bill the property owner.
