FIRE HAZARDOUS PLANTS
|
Inspectors may note the presence of specific species of fire hazardous or "pyrophytic" (or "fire-prone") plants present within 30' of structures or 10' of roads and driveways on your property. Section 4907.2 of the California Fire Code, as amended and adopted by your fire agency, requires removal of pyrophytic, combustible vegetation within 30' of structures and/or 10’ of roads or driveways.
See FIRESafe MARIN's list of fire-prone plants in Marin.
What should I do? Please remove these plans and replace with a fire resistant species. If the removal creates a hardship, please contact us for assistance - in some cases, we can help you modify vegetation or create a plan to remove and replace vegetation over time
|
1. REMOVE ALL BRANCHES WITHIN 10’ OF ANY CHIMNEY OR STOVEPIPE OUTLET.
|
Inspectors noted a tree limb or shrub(s) that are too close to your chimney.
What should I do? Please cut back limbs with foliage that are within 10' of a chimney outlet. Limbs must be cut back even if you don't plan to use the fireplace, or if you have a gas stove or insert. Contact us if removing the limb would cause harm to the structure or health of the tree.

|
2. REMOVE ALL LEAVES, NEEDLES AND DEAD VEGETATION ON ROOFS, GUTTERS, DECKS, PORCHES, STAIRWAYS, ETC.
|
Inspectors observed leaves and needles on your roof or rain gutters, or on decks, porches, and outdoor stairs. This is the most significant hazard found on most homes, and is the most likely source of ignition during a wildfire. Even one handful of leaves or needles may be enough to burn your home down.
What should I do? Please regularly remove fallen leaves, needles, twigs, and other dead vegetation from your roof, rain gutters, decks, proches, exterior stairs, and from around the base of exterior walls.
Fire Code Reference [2016 CFC §4907.2, PRC §4291(a)(6)]
|
3. REMOVE ALL DEAD AND DYING TREES, BRANCHES, SHRUBS, AND PLANTS ADJACENT TO BUILDINGS OR OVERHANGING ROOFS.
|
Inspectors observed dead trees, branches, shrubs or plants adjacent to a structure or overhanging a roof. This may be your home, decks, or an accessory structure like a garage, cottage, shed, or play structure.
What should I do? Please remove any dead vegetation immediately adjacent to or overhanging structures on your property (typically within 5-10 feet). Look for dead limbs in trees and dead shrubs. Some shrubs may have dead woody vegetation beneath a visible layer of green foliage.
Fire Code Reference [2016 CFC §4907.2]
|
4. REMOVE ALL DEAD GRASS, PLANTS, SHRUBS, TREES, BRANCHES, LEAVES, WEEDS AND NEEDLES WITHIN 30’ OF STRUCTURES.
|
Inspectors observed dead vegetation within 30' of structures.
What should I do? Please remove any dead vegetation within 30' of structures. Look for dead grasses, shrubs, landscaping plants or bnative vegetation. Some shrubs may have dead woody vegetation beneath a visible layer of green foliage. This may include fallen limbs and leaves.
Fire Code Reference [2016 CFC §4907.2]
|
5. REMOVE OR SEPARATE LIVE COMBUSTIBLE GROUND COVER AND SHRUBS WITHIN 30’ OF STRUCTURES.
|
Some live plants or even fire-resistant plant species can burn if they are not adequately maintained and irigated. Inspectors observed LIVE plants in a combustible state near your home.
What should I do? Please remove or add separation betwen shrubs to prevent fire from spreading between individual plants. This may require pruning shrubs or removal when plantings are dense or close together. This often refers to plants such as juniper, rosemary, some ornamental grasses, some bamboo species, and other combustible species. See www, firesafemarin.org/plants for details on fire hazardous plants.

|
6. REMOVE COMBUSTIBLE VEGETATION AND MATERIALS, ON, ADJACENT TO, OR BELOW COMBUSTIBLE DECKS, BALCONIES, STAIRS.
|
Decks, balconies, and stairs are particularly vulnerable to ignition from flames or embers during a wildfire. They must be maintained clear of all vegetation debris and materials, including fallen leaves and needles, and combustible furniture and materials above and below.
What should I do? Please look for vegetation beneath decks, porches, balconies and exterior stairs. Remove all vegetation growing beneath these structures to prevent the spread of fire to vulnerable undersides of overhangs and decks. Remove or replace combustible furniture and materials such as wicker or wooden furniture, firewood, or jute doormats. Do not store exposed combustibles such as lumber or boxes beneath decks or overhangs. Consider enclosing the underside of decks with with a solid wall or wire-mech screening. Redwood lattice is highly combustible and should not be used to cscreen the underside of decks.
Fire Code Reference [14 CCR §1299.03(a)(4)]
|
7. RELOCATE EXPOSED FIREWOOD OR LUMBER OUTSIDE OF ZONE 1 UNLESS COVERED IN A FIRE RESISTIVE MATERIAL.
|
Inspectors observed exposed firewood or lumber stored too close to structure(s).
What should I do? Firewood may not be stored exposed on decks or adjacent to structures. Please relocate or cover firewood and lumber piles. You may move piles more than 30' from structures, move them indoors, or alternately cover them tightly with a fire resistant cover (such as a heavy tarp or canvas, or in a tightly enclosed shed - no specific "fire resistant cover product" exists) to prevent embers from igniting the wood. Storing firewood indoors in a garage or shed is better than leaving it exposed. Keep firewood piles free of leaves, needles, and fine vegetation that can act as "kindling" and ignite from embers during a wildfire.
Fire Code Reference [14 CCR §1299.03(a)(3)]
|
8. CUT ANNUAL GRASSES AND FORBS (WEEDS) TO A MAXIMUM OF 4” IN HEIGHT.
|
Dry grasses are a significant risk, carrying wildfires quickly and igniting readily from embers.
What should I do? Please mow or cut all dry, cured grasses and weeds to a maximum of 4" in height. Cut grasses may remain on ground (no deeper than 4"), however we recommend raking and removing clippings for maximum fire-resistance. You may need to cut grasses more than once each year if they grow back, so don't assume that everything is "OK" because you cut grasses earlier in the year.
Use plastic string trimmers, and be sure to only use gas powered mowers in the morning when vegetation is moist and temperatures are cool. Metal bladed mowers and trimmers can spark fires. Never use outdoor power tools on a Red Flag day.
Fire Code Reference [2016 CFC §4907.2, 14 CCR §1299.03(b)(2)(B)]
|
9. PROVIDE SEPARATION BETWEEN SHRUBS AND TREES, WITH INCREASED SEPARATION ON SLOPES.
|
Shrubs and trees that are too close together can help spread fire from plant to plant. Even fire-resistant plants should have some separation, and shrubs should not be allowed to grow below trees.
What should I do? Please remove any shrubs growing beneath trees which create "ladder fuels" to carry fire from the ground into trees. Provide separation between shrubs and trees by pruning aggressively or removing individual plants. Add additional space on slopes. Follow the helpful guidelines in this FIRESafe MARIN brochure to ensure compliance.
A continuous canopy of fire-resistant trees may be desireable in some cases to create shade (sometimes refrerred to as a "shaded fuel-break") which can suppress weeds and grasses, and help retain moisture. Consult with an arborist or your fire department for advice before removing shade providing trees (unless they are a fire-prone species).

|
10. CUT AND REMOVE ALL FIRE HAZARDOUS COMBUSTIBLE VEGETATION WITHIN 30’ OF STRUCTURES.
|
Inspectors observed one or more FIRE HAZARDOUS plants within 30' of structures.
What should I do? Fire Hazardous vegetation must be removed within 30' of structures. Fire hazardous vegetation includes dry grasses & weeds, juniper, some species of bamboo, pampas/jubata grasses, Scotch/French broom, and many conifer trees. See a list of common fire-prone plants at FIRESafe MARIN.
Fire Code Reference [2016 CFC §4907.2]
|
11. REMOVE ALL PILES OF ACCUMULATED DEAD VEGETATION ON THE PROPERTY.
|
Inspectors observed piles of accumulated dead vegetation on the property.
What should I do? Please remove all piles of dead vegetation on property, regardless of the distance to structures.
Fire Code Reference [2016 CFC §4907.2]
|
12. REMOVE TREE LIMBS AND GROWTH LESS THAN 3” DIAMETER TO 10’ ABOVE GROUND (OR 1/3 THE TREE'S HEIGHT).
|
Tree limbs that are too close to the ground can help carry fire into the tree's canopy, even in fire-resistant species.
What should I do? Please remove lower tree limbs to ensure no limbs with foliage are within 10' of the ground, unless the tree is less than 30' tall - in which case you should remove limbs to 1/3 the height of the tree. Please contact us if this would cause harm to the structure or health of the tree.
Fire Code Reference [2016 CFC §4907.2, PRC §4291(a)]
|
13. VEGETATION CLEARANCE ADJACENT TO ROADS AND/OR DRIVEWAYS MUST BE MAINTAINED 10’ HORIZONTALLY AND 14’ VERTICALLY.
|
Inspectors observed unmaintained or dead vegetation adjacent to a road or driveway, or tree limbs or shrubs overhanging the roadway. Property owners are required to maintain vegetation adjacent to any road or driveway fronting their property, even in the public right-of-way between a property line and the pavement's edge.
What should I do? Vegetation adjacent to roads and driveways must be maintained for 10' (horizontally) and 14' vertically. Vegetation must be maintained in the same manner as if it were adjacent to structures. Overhead vegetation, including shrubs and tree limbs, must be cleared to a height of 14' above the driveable surface of the road or driveway for fire apparatus clearance.
Fire Code Reference [2016 CFC §4907.3]
|
14. ADDRESS NUMBERS MUST BE 4” MINIMUM, DISPLAYED IN CONTRASTING COLORS, AND READABLE FROM THE STREET.
|
Inspectors did not see an address number, or your address number is not adequately visible.
What should I do? Please install address numbers that are at least 4" tall and plainly visible from the street in both directions of travel. Numbers must be on a contrasting background to ensure visibility. Lighted numbers are best. Install numbers at all entrances if you have multiple driveways. Address numbers painted on a curb are not adequate.
Fire Code Reference [2016 CFC §505.1]
|
15. EQUIP ALL CHIMNEY OR STOVEPIPE OPENINGS WITH A METAL SCREEN HAVING OPENINGS BETWEEN 3/8” AND 1/2”.
|
Inspectors observed chimney(s) without a spark arrestor or ember screen.
What should I do? Please consult a chnimney professional to install a screen with 3/8" to 1/2" openings to prevent embers from escaping.
Fire Code Reference [2016 CBC §2113.9.2]
|
16. LOGS OR STUMPS EMBEDDED IN SOIL MUST BE REMOVED OR ISOLATED FROM VEGETATION WITHIN 100' OF STRUCTURES.
|
Inspectors observed logs or stumps that might ignite during a wildfire.
What should I do? This is uncommon. If a log or stump is present, clear vegetation 10' around it to prevent ignition.
Fire Code Reference [Applies only to SRA areas: BOF Guidelines #3. May be required in LRA areas under 2016 CFC §4907.2]
|
17. OUTBUILDINGS & PROPANE (LPG) TANKS MUST HAVE 10’ OF CLEARANCE TO BARE MINERAL SOIL.
|
Inspectors observed vegetation or combustibles adjacent to a propane tank.
What should I do? Most properties in Kentfield do not have exterior propane tanks. If you do, 10' of clearance is required with no vegetation allowed for screening. Combustible screens (redwood lattice, for example) are not permitted within 10' of propane tanks.
