Weed and Brush Management

defensible space burn

PLEASE NOTE: IF YOU HAVE RECEIVED A WEED ABATEMENT NOTICE REQUIRING ABATEMENT BY MAY 1, 2023, THESE NOTICES WERE SENT IN ERROR. PLEASE DISREGARD. The correct notices are dated April 21, 2023, requesting abatement by May 21, 2023. See additional information below. 

As of April 21, 2023, annual courtesy notices have gone out to all property owners within the Very High Fire Hazard Severity Zone as well as to vacant properties within the City. 

Creating a defensible space around your home can make the difference between whether or not your home can survive a wildfire. The City’s Weed and Brush Management program is governed by the Murrieta Municipal Code, Title 8, Chapter 8.32. Property owners in the City of Murrieta are required to maintain their property in a clean and safe condition throughout the entire year. This responsibility is especially important during the fire season, from March through September, to keep our community safe.

Fire inspectors will begin performing field inspections on May 22, 2023, to further identify required mitigations. At that time, property owners will either be confirmed compliant or will receive an additional notice to comply.  We are asking for your assistance in identifying and completing required mitigation on your property prior to May 22, 2023 

See the link below for more information on what may be considered a violation on your property.

Violation Explanations

Weed Abatement Contractor List


Properties Five Acres in Size or Less

  • All weeds must be abated.
  • Discing, mowing, or weed whacking is acceptable.

Note:  Mowing must be completed in such a manner that the remaining weeds/vegetation are less than 4 inches in height. For safety reasons, mowing should occur in the morning between 8:30 and 11A.M.

Properties Over Five Acres in Size

  • Minimum 100 feet firebreak, along the perimeter and through the parcel, so that no portion is larger than 2.5 acres.

Hillside Residential Properties

  • Structures or improvements must have 100 feet of clearance from any flammable/combustible material or dry weeds or vegetation.

Agricultural Property

  • Minimum 25 feet firebreak along the perimeter of property and from edge of road.
  • Minimum 100 feet firebreak from the improved property.


During warm days, especially when humidity is below 20 percent, do not mow. Fires can be started by mowing during high-risk fire weather conditions.


Due to uncontrolled regrowth of weeds and vegetation, it may be necessary to abate your property several times during the year. All dead, dying, or diseased trees and shrubs must be removed! Unfortunately, some of the vegetation has gone from being decorative to becoming a potential fire hazard, such as the:

  • California Pepper
  • Certain Acacia species
  • Eucalyptus
  • Oaks
  • Oleander
  • Pine
  • Palm

This past year, there has been an increase in the amount of tree and shrub mortality brought on by prolonged drought, insect infestation, disease, and lack of maintenance. Remove all dead and diseased vegetation within 100 feet from your home to reduce the exposure.

Other Things to Watch Out For

  • Tree branches must be trimmed back at least 10 feet from rooftops and fireplace chimneys.
  • Propane tanks need 20 feet of clearance from dead or dying vegetation or combustible material.
  • Move woodpiles and trash cans away from your home. Firewood must be neatly stacked and have a minimum of 30 feet of clearance from a structure. When possible, trash enclosures or trash can storage should be 10 feet away from a structure. Remember to keep lids on all trash cans.
  • Combustible mulch or wood chips should not be closer than 12 inches to prevent a fire from being transmitted to an exterior wall.


If the property is found to be in violation of the Municipal Code, the property owner will be notified by mail to promptly address the violation. If no visible attempt is made to clean up the property within 15 days, the City may abate the property and bill the property owner for the abatement cost.
