CHAPTER 6.8. Moderate, High, and Very High Fire Hazard Severity Zones [51175. - 51189.]

Cal. Government Code - GOV 6.8.
in effect

Cal. Government Code - GOV § 51175. Section 51175.

The Legislature hereby finds and declares as follows: (a) Wildfires are extremely costly, not only to property owners and residents, but also to local agencies. Wildfires pose a serious threat to the preservation of the public peace, health, or safety. The wildfire front is not the only source of risk since embers, or firebrands, travel far beyond the area impacted by the front and pose a risk of ignition to a structure or fuel on a site for a longer time. Since fires ignore civil boundaries, it is necessary that cities, counties, special districts, state agencies, and federal agencies work together to bring raging fires under control. Preventive measures are therefore needed to ensure the preservation of the public peace, health, or safety. (b) The prevention of wildland fires is not a municipal affair, as that term is used in Section 5 of Article XI of the California Constitution, but is instead, a matter of statewide concern. It is the intent of the Legislature that this chapter apply to all local agencies, including, but not limited to, charter cities, charter counties, and charter cities and counties. This subdivision shall not limit the authority of a local agency to impose more restrictive fire and public safety requirements, as otherwise authorized by law. (c) It is not the intent of the Legislature in enacting this chapter to limit or restrict the authority of a local agency to impose more restrictive fire and public safety requirements, as otherwise authorized by law.

Cal. Government Code - GOV § 51176. Section 51176.

The purpose of this chapter is to classify lands in the state in accordance with whether a very high fire hazard is present so that public officials are able to identify measures that will retard the rate of spread, and reduce the potential intensity, of uncontrolled fires that threaten to destroy resources, life, or property, and to require that those measures be taken.

Cal. Government Code - GOV § 51177. Section 51177.

As used in this chapter: (a) “Defensible space” means the area adjacent to a structure or dwelling where wildfire prevention or protection practices are implemented to provide defense from an approaching wildfire or to minimize the spread of a structure fire to wildlands or surrounding areas. (b) “Director” means the Director of Forestry and Fire Protection. (c) “Fuel” means any combustible material, including petroleum-based products, cultivated landscape plants, grasses, and weeds, and wildland vegetation. (d) “Fuel management” means the act or practice of controlling flammability and reducing resistance to control of fuels through mechanical, chemical, biological, or manual means or by fire, in support of land management objectives. (e) “Local agency” means a city, county, city and county, or district responsible for fire protection within a very high fire hazard severity zone. (f) “Single specimen tree” means any live tree that stands alone in the landscape so as to be clear of buildings, structures, combustible vegetation, or other trees, and that does not form a means of rapidly transmitting fire from the vegetation to an occupied dwelling or structure or from an occupied dwelling or structure to vegetation. (g) “State responsibility areas” means those areas identified pursuant to Section 4102 of the Public Resources Code. (h) “Vegetation” means all plants, including trees, shrubs, grass, and perennial or annual plants. (i) “Very high fire hazard severity zone” means an area designated as a very high fire hazard severity zone by the State Fire Marshal pursuant to Section 51178 that is not a state responsibility area. (j) “Wildfire” means an unplanned, unwanted wildland fire, including unauthorized human-caused fires, escaped wildland fire use events, escaped prescribed fire projects, and all other wildland fires where the objective is to extinguish the fire.

Cal. Government Code - GOV § 51178. Section 51178.

The State Fire Marshal shall identify areas in the state as moderate, high, and very high fire hazard severity zones based on consistent statewide criteria and based on the severity of fire hazard that is expected to prevail in those areas. Moderate, high, and very high fire hazard severity zones shall be based on fuel loading, slope, fire weather, and other relevant factors including areas where winds have been identified by the Office of the State Fire Marshal as a major cause of wildfire spread.

Cal. Government Code - GOV § 51178.5. Section 51178.5.

Within 30 days after receiving a transmittal from the State Fire Marshal that identifies fire hazard severity zones pursuant to Section 51178, a local agency shall make the information available for public review and comment. The information shall be presented in a format that is understandable and accessible to the general public, including, but not limited to, maps.

Cal. Government Code - GOV § 51179. Section 51179.

(a) A local agency shall designate, by ordinance, moderate, high, and very high fire hazard severity zones in its jurisdiction within 120 days of receiving recommendations from the State Fire Marshal pursuant to Section 51178. (b) (1) A local agency may, at its discretion, include areas within the jurisdiction of the local agency, not identified as very high fire hazard severity zones by the State Fire Marshal, as very high fire hazard severity zones following a finding supported by substantial evidence in the record that the requirements of Section 51182 are necessary for effective fire protection within the area. (2) A local agency may, at its discretion, include areas within the jurisdiction of the local agency, not identified as moderate and high fire hazard severity zones by the State Fire Marshal, as moderate and high fire hazard severity zones, respectively. (3) A local agency shall not decrease the level of fire hazard severity zone as identified by the State Fire Marshal for any area within the jurisdiction of the local agency, and, in exercising its discretion pursuant to paragraph (2), may only increase the level of fire hazard severity zone as identified by the State Fire Marshal for any area within the jurisdiction of the local agency. (c) The local agency shall transmit a copy of an ordinance adopted pursuant to subdivision (a) to the State Board of Forestry and Fire Protection within 30 days of adoption. (d) Changes made by a local agency to the recommendations made by the State Fire Marshal shall be final and shall not be rebuttable by the State Fire Marshal. (e) The State Fire Marshal shall prepare and adopt a model ordinance that provides for the establishment of very high fire hazard severity zones. (f) Any ordinance adopted by a local agency pursuant to this section that substantially conforms to the model ordinance of the State Fire Marshal shall be presumed to be in compliance with the requirements of this section. (g) A local agency shall post a notice at the office of the county recorder, county assessor, and county planning agency identifying the location of the map provided by the State Fire Marshal pursuant to Section 51178. If the agency amends the map, pursuant to subdivision (b) or (c) of this section, the notice shall instead identify the location of the amended map.

Cal. Government Code - GOV § 51180. Section 51180.

For the purposes of Division 3.6 (commencing with Section 810) of Title 1, vegetation removal or management, undertaken in whole or in part, for fire prevention or suppression purposes shall not be deemed to alter the natural condition of public property. This section shall apply only to natural conditions of public property and shall not limit any liability or immunity that may otherwise exist pursuant to this chapter.

Cal. Government Code - GOV § 51181. Section 51181.

The State Fire Marshal shall periodically review the areas in the state identified as very high fire hazard severity zones pursuant to this chapter, and as necessary, shall make recommendations relative to very high fire hazard severity zones. This review shall coincide with the review of state responsibility area lands every five years and, when possible, fall within the time frames for each county’s general plan update. Any revision of areas included in a very high fire hazard severity zone shall be made in accordance with Sections 51178 and 51179.

Cal. Government Code - GOV § 51182. Section 51182.

(a) The State Board of Forestry and Fire Protection shall adopt regulations to implement the rules described in this subdivision. Pursuant to these regulations, a person who owns, leases, controls, operates, or maintains an occupied dwelling or occupied structure within a very high fire hazard severity zone designated by the local agency pursuant to Section 51179, shall at all times do all of the following: (1) (A) Maintain defensible space of 100 feet from each side and from the front and rear of the structure, but not beyond the property line except as provided in subparagraph (B). The amount of fuel modification necessary shall consider the flammability of the structure as affected by building material, building standards, location, and type of vegetation. Fuels shall be maintained and spaced in a condition so that a wildfire would be unlikely to ignite the structure. This subparagraph does not apply to single specimens of trees or other vegetation that are well-pruned and maintained so as to effectively manage fuels and not form a means of rapidly transmitting fire from other nearby vegetation to a structure or from a structure to other nearby vegetation or to interrupt the advance of embers toward a structure. The intensity of fuels management may vary within the 100-foot perimeter of the structure, with more intense fuel reductions being used between 5 and 30 feet around the structure, and an ember-resistant zone being required within 5 feet of the structure, based on regulations promulgated by the State Board of Forestry and Fire Protection, in consultation with the Office of the State Fire Marshal, to consider the elimination of materials in the ember-resistant zone that would likely be ignited by embers. The regulations may also alter the fuel reduction required between 5 and 30 feet to integrate the ember-resistant zone into the requirements of this section. Consistent with fuels management objectives, steps should be taken to minimize erosion, soil disturbance, and the spread of flammable nonnative grasses and weeds. (B) A greater distance than that required under subparagraph (A) may be required by state law, local ordinance, rule, or regulation. Fuel modification beyond the property line may only be required by state law, local ordinance, rule, or regulation in order to maintain 100 feet of defensible space from a structure. Fuel modification on adjacent property shall only be conducted following written consent by the adjacent landowner. Any local ordinance related to fuel modification shall be in compliance with all applicable state laws, regulations, and policies. Any local ordinance may include provisions to allocate costs for any fuel modification beyond the property line. (C) An insurance company that insures an occupied dwelling or occupied structure may require a greater distance than that required under subparagraph (A) if a fire expert, designated by the fire chief or fire official from the authority having jurisdiction, provides findings that the fuel modification is necessary to significantly reduce the risk of transmission of flame or heat sufficient to ignite the structure, and there is no other feasible mitigation measure possible to reduce the risk of ignition or spread of wildfire to the structure. The greater distance may not be beyond the property line unless allowed by state law, local ordinance, rule, or regulation. (2) Remove that portion of a tree that extends within 10 feet of the outlet of a chimney or stovepipe. (3) Maintain a tree, shrub, or other plant adjacent to or overhanging a building free of dead or dying wood. (4) Maintain the roof of a structure free of leaves, needles, or other vegetative materials. (5) Before constructing a new dwelling or structure that will be occupied or rebuilding an occupied dwelling or occupied structure damaged by a fire in that zone, the construction or rebuilding of which requires a building permit, the owner shall obtain a certification from the local building official that the dwelling or structure, as proposed to be built, complies with all applicable state and local building standards, including those described in subdivision (b) of Section 51189, and shall provide a copy of the certification, upon request, to the insurer providing course of construction insurance coverage for the building or structure. Upon completion of the construction or rebuilding, the owner shall obtain from the local building official a copy of the final inspection report that demonstrates that the dwelling or structure was constructed in compliance with all applicable state and local building standards, including those described in subdivision (b) of Section 51189, and shall provide a copy of the report, upon request, to the property insurance carrier that insures the dwelling or structure. (b) A person is not required under this section to manage fuels on land if that person does not have the legal right to manage fuels, nor is a person required to enter upon or to alter property that is owned by any other person without the consent of the owner of the property. (c) (1) The State Board of Forestry and Fire Protection, in consultation with the Office of the State Fire Marshal, shall develop, periodically update, and post on its internet website a guidance document on fuels management pursuant to this chapter. The guidance document shall include, but not be limited to, regionally appropriate vegetation management suggestions that preserve and restore native species that are fire resistant or drought tolerant, or both, minimize erosion, minimize the spread of flammable nonnative grasses and weeds, minimize water consumption, and permit trees and shrubs near homes for shade, aesthetics, and habitat; and suggestions to minimize or eliminate the risk of flammability of nonvegetative sources of combustion such as woodpiles, propane tanks, decks, and outdoor lawn furniture. (2) No later than one year after the State Board of Forestry and Fire Protection adopts regulations in compliance with the deadline in Executive Order No. N-18-25, the State Board of Forestry and Fire Protection shall, in consultation with the Office of the State Fire Marshal, update the guidance document to reflect the new regulations. (d) Existing and new structures shall meet the same standard for the ember-resistant zone, but the regulations adopted by the State Board of Forestry and Fire Protection pursuant to this section shall allow the staging of work for existing structures to support implementation of the ember-resistant zone and address the costs of compliance. (e) For purposes of this section, a structure for the purpose of an ember-resistant zone shall include any attached deck. This section does not limit the authority of the State Board of Forestry and Fire Protection or the Office of the State Fire Marshal to require the removal of fuel or vegetation on top of or underneath a deck pursuant to this section. (f) (1) A local agency responsible for fire protection may designate, by ordinance, defensible space requirements based on regulations promulgated by the State Board of Forestry and Fire Protection pursuant to subdivision (a). In developing the ordinance, a local agency may, in order to meet the intent of the State Board of Forestry and Fire Protection regulations, consider local variations in local fire hazards, geography, development, and other conditions and authorize alternative practices to those in the State Board of Forestry and Fire Protection regulations, if the alternative practices provide for substantially similar practical effects as those stated in the State Board of Forestry and Fire Protection regulations. This subdivision does not preclude a local agency from adopting an ordinance designating defensible space requirements that are more stringent than the regulations adopted by the State Board of Forestry and Fire Protection pursuant to subdivision (a). (2) For purposes of Sections 51185, 51186, 51187, and any other laws imposing penalties for violations of this section, or any other laws otherwise requiring compliance with this section, a property owner in compliance with the applicable alternative practices adopted by that property owner’s local agency in an ordinance described in paragraph (1) shall not be deemed to have violated this section. (3) For purposes of this subdivision, “property owner” means a person who owns, leases, controls, operates, or maintains an occupied dwelling or occupied structure within a very high fire hazard severity zone designated by the local agency pursuant to Section 51179, as described in subdivision (a).

Cal. Government Code - GOV § 51182.4. Section 51182.4.

(a) The State Board of Forestry and Fire Protection shall adopt regulations to implement defensible space requirements for an ember-resistant zone required within five feet of a structure in the state responsibility area pursuant to Section 4291 of the Public Resources Code and a very high fire hazard severity zone pursuant to Section 51182 of this code. (b) If adopting the regulations described in subdivision (a) through the regular rulemaking process pursuant to Chapter 3.5 (commencing with Section 11340) of Part 1 of Division 3 of Title 2 would inhibit compliance with the December 31, 2025, deadline in Executive Order No. N-18-25, the regulations shall instead be adopted as emergency regulations, in which case the adoption of initial regulations shall be deemed in response to an emergency and the Office of Administrative Law shall consider the adoption of initial regulations as necessary for the immediate preservation of the public peace, health, safety, and general welfare. (c) The State Board of Forestry and Fire Protection may readopt any emergency regulation authorized by this section that is the same as or substantially equivalent to an emergency regulation previously adopted pursuant to this section. (d) Notwithstanding Chapter 3.5 (commencing with Section 11340) of Part 1 of Division 3 of Title 2, any emergency regulations adopted or readopted pursuant to this section shall remain in effect until revised by the State Board of Forestry and Fire Protection. (e) The adoption or readoption of the regulations described in this section shall not constitute a project for purposes of Division 13 (commencing with Section 21000) of the Public Resources Code.

Cal. Government Code - GOV § 51183. Section 51183.

(a) The local agency may exempt from the standards set forth in Section 51182 structures with exteriors constructed entirely of nonflammable materials, or conditioned upon the contents and composition of the structure, and may vary the requirements respecting the management of fuels surrounding the structures in those cases. This subdivision does not authorize a local agency to vary a requirement that is a building standard subject to Section 18930 of the Health and Safety Code, except as otherwise authorized by law. (b) An exemption or variance under subdivision (a) shall not apply unless and until the occupant of the structure, or if there is no occupant, then the owner of the structure, files with the local agency a written consent to the inspection of the interior and contents of the structure to ascertain whether Section 51182 is complied with at all times.

Cal. Government Code - GOV § 51183.5. Section 51183.5.

(a) A transferor of real property that is located within a very high fire hazard severity zone, designated pursuant to this chapter, shall disclose to any prospective transferee the fact that the property is located within a very high fire hazard severity zone, and is subject to the requirements of Section 51182. (b) Disclosure is required pursuant to this section only when one of the following conditions is met: (1) The transferor, or the transferor’s agent, has actual knowledge that the property is within a very high fire hazard severity zone. (2) A map that includes the property has been provided to the local agency pursuant to Section 51178, and a notice is posted at the offices of the county recorder, county assessor, and county planning agency that identifies the location of the map and any information regarding changes to the map received by the local agency. (c) In all transactions that are subject to Section 1103 of the Civil Code, the disclosure required by subdivision (a) of this section shall be provided by either of the following means: (1) The Local Option Real Estate Disclosure Statement as provided in Section 1102.6a of the Civil Code. (2) The Natural Hazard Disclosure Statement as provided in Section 1103.2 of the Civil Code. (d) If the map or accompanying information is not of sufficient accuracy or scale that a reasonable person can determine if the subject real property is included in a very high fire hazard zone, the transferor shall mark “Yes” on the Natural Hazard Disclosure Statement. The transferor may mark “No” on the Natural Hazard Disclosure Statement if he or she attaches a report prepared pursuant to subdivision (c) of Section 1103.4 of the Civil Code that verifies the property is not in the hazard zone. Nothing in this subdivision is intended to limit or abridge any existing duty of the transferor or the transferor’s agents to exercise reasonable care in making a determination under this subdivision. (e) Section 1103.13 of the Civil Code shall apply to this section. (f) The specification of items for disclosure in this section does not limit or abridge any obligation for disclosure created by any other provision of law or that may exist in order to avoid fraud, misrepresentation, or deceit in the transfer transaction.

Cal. Government Code - GOV § 51184. Section 51184.

(a) Section 51182 shall not apply to any land or water area acquired or managed for one or more of the following purposes or uses: (1) Habitat for endangered or threatened species, or any species that is a candidate for listing as an endangered or threatened species by the state or federal government. (2) Lands kept in a predominantly natural state as habitat for wildlife, plant, or animal communities. (3) Open space lands that are environmentally sensitive parklands. (4) Other lands having scenic values, as declared by the local agency, or by state or federal law. (b) This exemption applies whether the land or water area is held in fee title or any lesser interest. This exemption applies to any public agency, any private entity that has dedicated the land or water areas to one or more of those purposes or uses, or any combination of public agencies and private entities making that dedication. (c) This section shall not be construed to prohibit the use of properly authorized prescribed burning to improve the biological function of land or to assist in the restoration of desired vegetation. (d) In the event that any lands adjacent to any land or water area described in subdivision (a) are improved such that they are subject to Section 51182, the obligation to comply with Section 51182 shall be with the person owning, leasing, controlling, operating, or maintaining the occupied dwelling or occupied structure on the improved lands. All maintenance activities and other fire prevention measures required by Section 51182 shall be required only for the improved lands, not the land and water areas described in subdivision (a).

Cal. Government Code - GOV § 51185. Section 51185.

(a) A violation of Section 51182 is an infraction punishable by a fine of not less than one hundred dollars ($100) nor more than five hundred dollars ($500). (b) If a person is convicted of a second violation of Section 51182 within five years, that person shall be punished by a fine of not less than two hundred fifty dollars ($250) nor more than five hundred dollars ($500). (c) If a person is convicted of a third violation of Section 51182 within five years, that person is guilty of a misdemeanor and shall be punished by a fine of not less than five hundred dollars ($500).

Cal. Government Code - GOV § 51186. Section 51186.

(a) The local agency having jurisdiction of property upon which conditions regulated by Section 51182 are being violated shall notify the owner of the property to correct the conditions. If the owner fails to correct the conditions, the local agency may cause the corrections to be made, and the expenses incurred shall become a lien on the property that is the subject of the corrections when recorded in the county recorder’s office in the county in which the real property is located. The priority of the lien shall be as of the date of recording. The lien shall contain the legal description of the real property, the assessor’s parcel number, and the name of the owner of record as shown on the latest equalized assessment roll. (b) (1) Each local agency having jurisdiction of property upon which conditions that are regulated by Section 51182 apply shall make reasonable efforts to provide notice to affected residents within the jurisdiction of the local agency describing the requirements added by the amendments to paragraph (1) of subdivision (a) of Section 51182 made in Assembly Bill 3074 of the 2019–20 Regular Session before the imposition of penalties for violating those requirements. (2) (A) The requirement for an ember-resistant zone pursuant to Section 51182 shall not take effect for new structures until the State Board of Forestry and Fire Protection updates the regulations, pursuant to paragraph (1) of subdivision (a) of Section 51182, and the guidance document, pursuant to paragraph (2) of subdivision (c) of Section 51182. (B) The requirements for an ember-resistant zone pursuant to Section 51182 shall take effect for existing structures three years after the effective date for the new structures.

Cal. Government Code - GOV § 51188. Section 51188.

In the instance of conflict between this chapter and any provision of state law that allows a regional planning agency to regulate very high fire hazard severity zones, this chapter shall prevail.

Cal. Government Code - GOV § 51189. Section 51189.

(a) The Legislature finds and declares that site and structure defensibility is essential to reduce the risk of structure ignition as well as for effective fire suppression by firefighters. This need to establish defensibility extends beyond the site fuel management practices required by this chapter, and includes, but is not limited to, measures that increase the likelihood of a structure withstanding ignition, such as building design and construction requirements that use fire resistant building materials, and standards for reducing fire risks on structure projections, including, but not limited to, porches, decks, balconies and eaves, and structure openings, including, but not limited to, attic, foundation, and eave vents, doors, and windows. (b) No later than January 31, 2020, the State Fire Marshal, in consultation with the director and the Director of Housing and Community Development, shall, pursuant to Section 18930 of the Health and Safety Code, recommend updated building standards that provide for comprehensive site and structure fire risk reduction to protect structures from fires spreading from adjacent structures or vegetation and to protect vegetation from fires spreading from adjacent structures, based on information learned from the 2017 wildfire season. (c) (1) No later than January 31, 2020, the State Fire Marshal, in consultation with the director and the Director of Housing and Community Development, shall develop a list of low-cost retrofits that provide for comprehensive site and structure fire risk reduction to protect structures from fires spreading from adjacent structures or vegetation and to protect vegetation from fires spreading from adjacent structures. The Department of Forestry and Fire Protection shall incorporate the list in its fire prevention education and outreach efforts. (2) In addition to the requirements of paragraph (1), the list shall include a guidance document, including regionally appropriate vegetation management suggestions that preserve and restore native plant species that are fire resistant or drought tolerant, or both. (d) (1) The Office of the State Fire Marshal shall develop a model defensible space program that shall be made available for use by a city, county, or city and county in the enforcement of the defensible space provisions of Section 51182 of this code and subdivision (a) of Section 4291 of the Public Resources Code. In the development of this program, the State Fire Marshal shall consult with representatives from local, state, and federal fire services, local government, building officials, utility companies, the building industry, insurers and insurance research organizations, and the environmental community. Components of the program shall include, but not be limited to, all of the following: (A) General guidelines for creating and maintaining defensible space around specified structures, including appropriate guidelines and definitions for vegetation management. (B) Provisions for fuel modification beyond the property line, including on unimproved lots, in order to maintain 100 feet of defensible space from a structure. (C) Suggested minimum qualifications needed for enforcement personnel. (D) Enforcement mechanisms for compliance with and maintenance of defensible space requirements, including, but not limited to, the following: (i) Site inspections. (ii) Procedures for notifying a property owner of a violation. (iii) Timelines for corrective action by a property owner and for reinspection. (iv) Citations requiring abatement of a violation and subsequent removal of a fire hazard within the defensible space boundaries. (v) Suggested administrative procedures that allow for appeal of the citation by the property owner. (2) If a defensible space program is adopted, the local agency for enforcement of this program may recover the actual cost of abatement and may cause a notice of abatement lien to be recorded in the county in which the real property is located. The notice shall, at a minimum, identify the record owner or possessor of the property, set forth the last known address of the record owner or possessor, set forth the date upon which abatement was ordered by the local agency and the date the abatement was completed, and include a description of the real property subject to the lien and the amount of the abatement cost. (3) The model defensible space program required pursuant to this subdivision shall be updated whenever the State Board of Forestry and Fire Protection substantially updates the guidance documents created pursuant to subdivision (c) of Section 51182 of this code and subdivision (e) of Section 4291 of the Public Resources Code. (4) In order to develop and implement this subdivision and support any required update of the guidance documents identified in subdivision (c) of Section 51182 of this code and subdivision (e) of Section 4291 of the Public Resources Code, the Office of the State Fire Marshal is authorized to expend funds from the Building Standards Administration Special Revolving Fund, upon an appropriation by the Legislature, pursuant to Section 18931.7 of the Health and Safety Code.
