If you live in Ross, you know wildfire season can feel personal. The combination of wooded hillsides, canyon winds, and older building materials puts many properties inside the Wildland-Urban Interface. You want a clear, local plan that protects your home and supports resale. This guide breaks down Ross-specific rules, priority steps, and resources so you can act with confidence. Let’s dive in.
Ross WUI: what it means for you
Ross is served by Ross Valley Fire Department, which maintains WUI maps, defensible-space programs, and resale inspections for Ross Valley towns. You can check your property’s location on the local maps through the Ross Valley Fire Department’s WUI resources. Explore the current maps and resources on the RVFD site: Ross Valley WUI maps and resources.
The Town of Ross also uses a Hillside Lot Ordinance for certain parcels. Depending on your location and project scope, hillside regulations may apply along with state WUI rules. Review the Town’s Title 18 zoning information and coordinate with the Building Department for site-specific guidance: Town of Ross Title 18 zoning.
Marin’s regional partners, including the Marin Wildfire Prevention Authority and Fire Safe Marin, support free or low-cost home evaluations, chipper days, and community programs. These services help you prioritize changes that reduce ignition risk around your home. Learn more about countywide programs at Marin Wildfire Prevention Authority.
Know the rules and who enforces them
- PRC Section 4291 sets the statewide baseline for defensible space within 100 feet of structures. This law requires clearing and fuel reduction based on local conditions. Review the statute here: California PRC 4291.
- Zone 0 (0 to 5 feet) standards are being finalized at the state level. Expect restrictions on combustible materials close to structures in very high hazard areas as rules roll out. Track updates on the Board of Forestry site: Defensible space zones, including Zone 0.
- New construction and many substantial remodels in WUI areas must meet Chapter 7A standards for fire-resistant roofs, vents, decks, windows, and siding. See background on materials and assemblies: Chapter 7A resources.
- Ross Valley Fire Department coordinates defensible-space evaluations and resale inspections. For permits and inspection coordination, start here: RVFD permits and construction information.
Defensible space by zone (0 to 100 feet)
Zone 0: 0 to 5 feet
- Replace combustible mulch with gravel, rock, or hardscape near structures, and keep this zone as clear as possible while state rules finalize. Learn what Zone 0 covers: State guidance on Zone 0.
- Remove planters, wood furniture, stacked firewood, and propane tanks from this area.
- Install metal mesh vent screens (1/16 to 1/8 inch) or listed WUI vents, and seal gaps at eaves and soffits.
- Sweep leaves and needles off decks and stairs, and do not store items under decks.
Zone 1: 5 to 30 feet
- Prune and separate plants so fire cannot move from the ground to shrubs to trees.
- Keep vegetation low and well-watered if allowed by local rules and water restrictions.
- Move woodpiles at least 30 feet from structures and avoid placing them uphill or downwind of the home when possible.
- Use your local evaluation to confirm spacing and priority tasks: Request a home evaluation.
Zone 2: 30 to 100 feet
- Thin brush, remove ladder fuels, and prune tree canopies for vertical and horizontal separation.
- Maintain annual clearance and keep grasses short through the season.
- Continue removing debris and combustible materials that could carry fire toward the house, in line with PRC 4291 requirements.
High-value upgrades that matter
Low-cost maintenance wins
- Clean gutters and roofs often, especially in fall and after wind events.
- Upgrade vent screens to non-plastic metal mesh and add proper spark arrestors at chimneys if needed.
- Clear under-deck areas and adjacent vegetation, and keep decks free of debris.
Medium-cost retrofits
- Roof: repair or replace with a Class A roof when possible, and keep valleys and edges free of debris.
- Windows: consider dual-pane tempered glass on vulnerable exposures and keep drapes closed during Red Flag days.
- Siding and decks: favor fire-resistant materials or add non-combustible skirting and enclosures around deck undersides.
Major investments
- Plan full Chapter 7A-level upgrades over time for roofs, vents, siding, windows, and decks. See code background here: Chapter 7A resources.
- Some owners consider exterior sprinkler or misting systems as a complement to defensible space. These systems require maintenance and may require permits.
Permits, inspections, and timing in Ross
If you plan to replace a roof, alter vents and eaves, rebuild decks, or change exterior openings, you will likely need permits. Because Ross uses Hillside Lot regulations for certain parcels, confirm if hillside standards apply to your project. Start with Town zoning and then coordinate with RVFD for fire code and WUI applicability: Town of Ross Title 18 zoning and RVFD permits and construction information.
For quick, actionable guidance, schedule a defensible-space and home-hardening evaluation and use the report to plan your work. You can also time vegetation projects with the county chipper program to reduce hauling costs. Check pickup dates for your area: Marin chipper days.
Grants, contractors, and insurance notes
Grant funding for residents has been offered in recent years through MWPA and local fire agencies, although availability changes by season. Review current announcements and program details on MWPA’s site: Marin Wildfire Prevention Authority and past grant notices here: MWPA resident grants announcement.
When hiring, look for contractors with WUI and Chapter 7A experience for roofs, vents, windows, siding, and decks. Ask for product spec sheets, verify licensing and insurance, and confirm permit needs before work begins. Many homeowners also find that documented hardening steps help with insurance reviews and strengthen buyer confidence during resale.
A simple Ross home-hardening plan
- Book an evaluation and walk the report with a contractor or your project lead. Use Fire Safe Marin’s evaluation program.
- Tackle Zone 0 this week. Remove mulch and combustibles near walls and upgrade vent screens.
- Prune, separate, and clean Zones 1 and 2. Schedule chipper days to dispose of green waste.
- Plan medium-cost retrofits over the next one to two years. Prioritize roof maintenance or replacement, windows, and siding on the most exposed sides.
- Confirm permits and inspections. Coordinate with the Town of Ross and RVFD using local permit resources.
