Wildfire in Marin County isn’t a headline. It’s smoke slipping through window screens, red flag texts at 6 a.m., and tenants asking if they should pack a bag.
If you own rentals in Novato, San Rafael, Mill Valley, or Sausalito, your homes sit where neighborhoods meet brush and wind.
Your job is to stay ahead: harden the building, keep the first five feet clear, teach tenants what to do, and keep proof of it all.
Do this well, and you protect people, preserve income, and make renewals, inspections, and the next red flag day less stressful.
In this article, we will tackle the exact steps that lower your risk: build defensible space, harden the structure, prepare and communicate with tenants, meet California requirements, and work with insurance.
Key Takeaways
- Most homes ignite from wind-blown embers, not the flame front.
- Zone 0, the first five feet, should be non-combustible.
- High-impact upgrades: ember-resistant vents or 1/16- to 1/8-inch mesh, Class A roof care, clean gutters.
- Tenant readiness: Alert Marin enrollment and mapped routes reduce confusion.
- Landlords may require renters’ insurance with loss-of-use benefits.
- Defensible space is required under PRC 4291 and Government Code 51182, with inspections.
Understanding Marin County’s Wildfire Risk
Marin County sits where neighborhoods meet open hillsides, a zone fire professionals call the wildland urban interface. Summers are dry, and the wind rushes through the canyons.
In a wildfire, tiny burning pieces called embers can fly far ahead of the flames. They land on roofs and in gutters, or blow through vents and small gaps. Many home losses start this way, not from a wall of fire.
The smart move is to focus on the house first. Keep the first five feet next to walls free of anything that burns, clean roofs and gutters often, and cover every vent with fine metal mesh so embers cannot get inside.
Defensible Space: Zones That Work Together
California law requires defensible space around homes. In Marin County, fire agencies inspect regularly. Manage it in three simple zones.
- Zone 0, 0 to 5 feet. Keep this strip non-combustible. Use gravel, pavers, or concrete: no bark mulch, wood piles, trash bins, or combustible furniture against walls. Remove plants and any limbs overhanging the roof. Clean roofs and gutters during fire season.
- Zone 1, 5 to 30 feet. Create space between plants and buildings. Remove dead leaves, weeds, and shrubs that can carry fire upward. Limb lower branches to about six to ten feet, or up to one-third of tree height if shorter. Choose well-watered, fire-smart plants.
- Zone 2, 30 to 100 feet. Thin rather than clear. Mow annual grasses to four inches or less. Break up continuous fuel patches, separate tree canopies, and remove leaf and branch piles while preserving healthy trees.
Home Hardening: Block Ember Intrusion
Most homes burn because wind-blown embers find a way in or land on something that can catch fire. Home hardening closes those openings and removes easy fuel right at the structure. Start with these high-impact fixes to make your building far more resistant in a single weekend.
Vents. Install ember-resistant vents or cover existing ones with metal mesh sized 1/16 to 1/8 inch. Protect the attic, soffit, crawlspace/foundation, and dryer vents; avoid plastic screens and ensure fasteners are secure.
Roof and gutters. Keep a Class A roof in good repair. Clear leaves from roofs and gutters often, and consider metal gutter covers to keep debris out where embers tend to land.
Windows and doors. Choose dual-pane units with at least one tempered pane. Close windows, exterior doors, and blinds before leaving to block embers and reduce heat exposure.
Fencing. Where a wood fence touches the house, replace the last five feet with a metal or other non-combustible section to keep fire from acting like a fuse to the wall.
Decks. Enclose the underside with ignition-resistant sheathing or fine mesh and seal gaps. Sweep out debris regularly and avoid storing anything under the deck.
Tenant Preparedness and Communication
Buildings can be repaired; people cannot. Give tenants a simple plan they can follow.
At move-in, have every household sign up for Alert Marin so they receive official warnings. Post a clear map with two ways out and tell tenants to leave early when orders come. Provide a go-bag list, medications, important documents, chargers, water, and essentials.
Maintain a reach-out tree: current phone numbers, text/email groups, and a quick test before peak fire weather. Ask tenants with access or functional needs to plan now for transportation, mobility aids, and caregiver support so evacuations are safe and smooth.
Legal and Insurance Essentials
Defensible space obligations. Owners must keep brush and vegetation controlled around each rental in wildfire-risk zones. Inspectors cite the property, not the tenant, so treat it as an owner's duty. Expect recurring checks in Marin County. Keep dated photos and invoices to show compliance.
Renter’s insurance. You can require renters to carry a policy. It protects their belongings and usually includes “loss of use” money for hotels and meals if fire damage makes a unit unlivable. Ask for proof at move-in and renewal, and set clear minimum coverage in the lease.
Mitigation and premiums. California now requires insurers to consider wildfire risk-reduction work when pricing policies. Many carriers, including the FAIR Plan, offer discounts for documented steps such as defensible space, ember-resistant vents, and Class A roofs. Submit photos and reports with renewal and ask your agent which credits apply.
Documentation and Ongoing Maintenance
Make wildfire work routine. Set quarterly reminders to photograph Zone 0, gutters, vents, decks, and fences. File invoices and before-and-after photos. Keep Alert Marin records in tenant files.
On red flag days, sweep roofs, clear under decks, and remove combustibles from Zone 0. Documentation supports renewals, inspections, and claims.
FAQ
Who is responsible for defensible space, me or the tenant?
The owner is responsible under California law. You can delegate yard tasks, but inspectors cite the property, not the resident.
Can I require renter’s insurance?
Yes. You can make it a lease condition, and most policies include loss-of-use benefits that help tenants with temporary housing.
What are the two best low-cost upgrades?
Keep Zone 0 non-combustible, and install ember-resistant vents or 1/16- to 1/8-inch metal mesh on all vents.
Will mitigation help with insurance?
Often, yes. State rules require insurers to account for risk reduction, and programs offer discounts with proof of defensible space and home hardening.
Turn Red Flag Days Into a Plan
Wildfire risk in Marin County is real, but it is manageable. Start at the house: keep the first five feet non-combustible, seal vents with fine metal mesh, maintain a Class A roof, and clean gutters. Build defensible space in Zones 0, 1, and 2. Prepare tenants with Alert Marin sign-ups, maps, and go-bags.
Meet California requirements, document work with photos and invoices, and submit mitigation proof to your insurer. These steps protect people, reduce damage, speed inspections, and support renewals.
