The first 5 feet around your home — Zone Zero — is where most wildfire ignitions begin. Knowles LumberCraft Construction is Marin County's CSLB-licensed home hardening contractor, specializing in outdoor fire improvements that protect your property and meet Cal Fire standards.
We assess your Marin County property, identify the highest-risk wildfire vulnerabilities, and complete all outdoor fire improvements to current Marin fire district and Cal Fire standards. Every project is priority-ranked — the most dangerous exposures get addressed first, so every dollar has maximum impact.
Sausalito, parts of Tiburon (Alto/Richardson Bay), and expanded Mill Valley neighborhoods were reclassified in 2025. If your neighborhood is newly designated, now is a good time to get a property walkthrough.
California law requires every home in a High or Very High Fire Hazard Severity Zone to pass a defensible space inspection before close of escrow — and since July 2025, sellers must also disclose the status of 12 specific home hardening conditions. Failing the inspection, or disclosing unaddressed vulnerabilities, can delay or derail your sale.
