Northern California’s 2026 fire season isn’t waiting for summer. As of May 2026, Cal Fire has declared early-season Red Flag conditions across the Sacramento Valley and Sierra Nevada foothills, weeks ahead of the historical average. The U.S. Drought Monitor shows more than 60% of Northern California in D2–D3 (severe to extreme) drought, driven by a snowpack that was 6% of the average, per the California Department of Water Resources.
In plain terms: the conditions that fueled the most destructive fires in California history are already here, and they’re here early. If you live anywhere in the Sacramento, Bay Area, or foothill regions, the time to prepare your property is right now, not in July.
The good news: preparation works. Research from the Insurance Institute for Business & Home Safety (IBHS) consistently shows that homes with well-maintained defensible space, cleared gutters, and ember-resistant construction features survive wildfires at significantly higher rates than unprepared homes. Every action you take this month improves your odds of protecting your family and property.
What’s Different About 2026
Several factors make this fire season uniquely dangerous, and homeowners should understand them before building their preparedness plan.
Diablo Wind events are already active. Forecasters at the National Weather Service Bay Area are tracking Diablo Wind patterns through late May across the North Bay and Central Valley foothills, with gusts of 15–40 mph and relative humidity below 15%. This is the same offshore wind pattern that drove the 2017 Tubbs Fire and 2019 Kincade Fire.
The insurance landscape has shifted. State Farm, Allstate, and Farmers have non-renewed tens of thousands of NorCal policies. FAIR Plan enrollment is at record highs.
Defensible space is now legally required for property sales. Under SB 901 and AB 38, 100-foot defensible space compliance is a condition of property sale in high-hazard zones. Cal Fire is ramping inspections, and local fire safe councils in Butte, El Dorado, and Placer counties run low-cost or sometimes free chipping programs, check their websites for the most up-to-date information.
Understanding NorCal’s Unique Fire Risk
Northern California faces near-perfect conditions for large, fast-moving wildfires. Steep terrain, dense vegetation, dry summers that drop fuel moisture to critical levels, and seasonal winds that push fires miles in hours. The wildland-urban interface — where homes meet undeveloped land — puts thousands of residences directly in fire’s path.
- Dry summers: June through October, California receives almost no rainfall, leaving vegetation extremely flammable.
- Wind events: Fall and spring winds can reach 40+ mph, spreading fire rapidly across large areas.
- Wildland-urban interface: Homes built near forests or open land face heightened exposure.
- Fuel buildup: Last winter’s heavy grass and brush growth has already cured. Dead fuel moisture in the Sierra foothills and North Bay is at critically low levels — Cal Fire and USFS have flagged Shasta, Trinity, Siskiyou, and Humboldt counties as high-priority pre-treatment zones.
The Checklist: Around the Home
Exterior defensible space is primary, but interior preparedness ensures you and your family can respond quickly if evacuation is needed. The National Fire Protection Association (NFPA) and Ready.gov provide additional guidance.
- Smoke alarms: test every month; replace batteries twice a year (use daylight saving time changes as a reminder). NFPA smoke alarm guidelines.
- Fire extinguishers: place ABC-rated units in the kitchen and garage; ensure family knows PASS (Pull, Aim, Squeeze, Sweep).
- Escape plan: identify two exits from each room; practice with children and visitors. Build your plan with NFPA.
- Meeting point: designate a safe outdoor location where everyone meets if separated.
- Room doors: keep them closed at night to slow smoke spread.
- Window coverings: avoid heavy drapes that catch fire easily.
The Checklist: Documents and Valuables
When evacuation is imminent, you won’t have time to search for documents. A fireproof safe or organized digital backup ensures critical information survives. FEMA’s Emergency Financial First Aid Kit is a free template for organizing critical documents.
- Homeowner’s insurance policy and agent contact information (save the number in your phone).
- Home inventory with photos or video (store digitally in cloud storage). The California Department of Insurance home inventory guide is a free starting point.
- Mortgage documents, property deeds, and titles.
- Medical records, prescriptions, and insurance cards.
- Irreplaceable family photos (scan and back up to cloud).
- Serial numbers for electronics and valuables (for insurance claims).
- Emergency contacts for family, doctor, and veterinarian.
Emergency Kit Essentials
Have a grab-and-go emergency kit ready at all times during fire season. Store it near your vehicle. Ready.gov’s Build a Kit guide covers the full recommended inventory.
- Water: one gallon per person per day for several days.
- Non-perishable food: granola bars, nuts, canned goods, and a manual can opener.
- Medications and first aid supplies.
- Copies of documents, insurance cards, and IDs.
- Cash and credit cards (ATMs may be offline during PSPS events).
- Phone chargers (both wall and car).
- Flashlight, batteries, and a battery-powered radio.
- Sturdy shoes and protective clothing for each family member.
- Pet carriers, food, medications, and vaccination records. Ready.gov pet preparedness.
Cal Fire’s Defensible Space Zones: The Official Standard
Cal Fire’s two-zone approach is the gold standard for fire-resistant property management.
Zone 1 (0–30 feet): The “Lean, Clean & Green” zone. Minimal vegetation, no dead plant material, trees spaced widely, ground clear of fallen leaves and branches. Requires spring and fall maintenance.
Zone 2 (30–100 feet): Provides space for firefighters to work and creates a buffer that reduces fire intensity as it approaches your home. Thin vegetation, space trees wider, remove lower branches. The goal is to break fuel continuity — preventing flames from climbing tree trunks and spreading canopy to canopy.
Under SB 901 and AB 38, this isn’t just best practice anymore. It’s the law for property sales in high-hazard zones, and Cal Fire is actively inspecting. Check your property’s hazard designation on the Cal Fire Fire Hazard Severity Zone Viewer.
Evacuation Warnings vs. Evacuation Orders: Know the Difference
During a fire event, local authorities issue evacuation alerts using a tiered system. Understanding these levels helps you react appropriately.
Evacuation Warning (Ready): Fire is not an immediate threat, but conditions are dangerous. Fill your vehicle with gas, gather go-bags, prepare documents. Do not delay — traffic can become impossible quickly.
Evacuation Order (Set): Fire may be approaching soon. Leave immediately. Do not wait for a second notice.
Evacuation Order (Go): Evacuate now. Conditions are extremely dangerous.
Do not wait for a warning to escalate before leaving. Once an order is issued, evacuation routes can gridlock, trapping you on roads with poor visibility and approaching fire. Stay informed through:
- Your county’s emergency alert system — sign up at CalAlerts.org
- The Watch Duty app — real-time fire information from verified sources
- Cal Fire incident updates
- A battery-powered emergency radio tuned to NOAA Weather Radio
If the Worst Happens: What to Do After a Fire
If your property is impacted by fire — even just smoke or soot damage — the steps you take in the first 24–48 hours significantly affect your recovery.
- Confirm it’s safe to return. Do not enter your property until authorities clear the area.
- Document everything before cleanup. Photo and video of every room, every surface, every damaged item. This is critical for your insurance claim.
- Contact your insurance carrier immediately. Ask about Additional Living Expenses (ALE) coverage if you’ve been displaced.
- Don’t wait to mitigate smoke and soot. Smoke damage is corrosive and gets worse the longer it sits. Acidic soot can permanently damage electronics, fixtures, and surfaces within days.
- Call a licensed restoration contractor for emergency services (ES). Board-up, tarping, water extraction, and contents pack-out should happen immediately to prevent secondary damage.
At Lawton Construction & Restoration, our emergency services team responds the same day for fire, smoke, and soot calls across the Sacramento Valley, Bay Area, and surrounding regions.
The Bottom Line
The 2026 fire season started early, and the conditions are more critical than in 2024. But every hour you spend on defensible space, every document you back up, every conversation you have with your family about evacuation — it all adds up. Homes that are prepared survive at dramatically higher rates than homes that aren’t.
Don’t wait for a Red Flag warning to turn into a recovery call. Whether you’re insured, on the FAIR Plan, or paying out of pocket, call (866) 990-5150 for a same-day fire, smoke, and soot assessment — or email help@lawtoncr.com.
