Zone 1 and Zone 2 Clearing — What CAL FIRE Requires
California's defensible space law sets two zones around a structure. Zone 1 is the 0–30 foot perimeter where the highest fuel reduction standard applies. Zone 2 covers 30–100 feet and requires thinning and spacing rather than complete clearance. We clear to these specs.
- Zone 1 (0–30 ft): remove dead plants, dry leaves, combustible debris, and ember-vulnerable vegetation
- Zone 1: maintain separation between shrubs and trees — no continuous fuel path to structure
- Zone 2 (30–100 ft): thin trees and shrubs for spacing, remove dead material and ladder fuels
- Zone 2: no requirement to remove all vegetation — fuel spacing and dead material removal
- Annual maintenance: CAL FIRE inspects SRA properties; clearance must be maintained seasonally

Which Sacramento Properties Need Defensible Space Clearing
The SRA and VHFHSZ boundary runs east of Sacramento proper. Checking your specific parcel is the only reliable way to know — neighborhood generalization is not sufficient.
- Core Sacramento: LRA — no state defensible space mandate
- East Sacramento fringe near Mather and Rancho Cordova: boundary varies by parcel
- Properties near Folsom Lake corridor: higher likelihood of SRA touch
- Check parcel designation: FHSZ viewer at osfm.fire.ca.gov
- CAL FIRE Unit Sacramento district covers SRA parcels — contact them for inspection scheduling
- Sacramento Fire Department covers LRA city lots — separate jurisdiction from CAL FIRE
What Defensible Space Clearing Does Not Mean
We're direct about what fuel reduction does and doesn't do. Clearing vegetation to CAL FIRE spec reduces fuel load near your structure; it does not eliminate wildfire risk.
- Fuel reduction clears ember-vulnerable materials and reduces fire intensity near structure
- Does not protect against direct flame contact, radiant heat, or ember intrusion through vents
- Structure ignitability (roofing, vents, decking material) matters as much as vegetation clearance
- Consult CAL FIRE for formal inspection and compliance confirmation — we clear the vegetation, they certify compliance
Frequently asked questions
Does my Sacramento property require defensible space clearing?
Only if your parcel is in an SRA or VHFHSZ — the majority of Sacramento city lots are LRA and are not subject to the 100-foot state requirement. Check your parcel at osfm.fire.ca.gov. East-side lots near Mather and the Folsom Lake foothills are the most likely Sacramento properties to have SRA designation.
How much does defensible space clearing cost for Sacramento east-side properties?
Zone 1 and Zone 2 clearing for a typical 5,000–10,000 sq ft residential lot runs $1,200–$4,000 depending on vegetation density and slope. Flat east-side lots near Mather tend to cost less than steeper foothills properties. Annual maintenance clearing is less expensive than initial establishment clearing.
Can CAL FIRE fail my property after you clear it?
Yes, if our work doesn't match their inspection standard on that visit. We clear to the published CAL FIRE Zone 1/Zone 2 spec. If an inspector identifies additional requirements specific to your parcel, we can return to address them — contact us with the inspection notes and we'll quote the additional work.
