Summary
In the City of Placentia, every new building built or installed in an area with or adjacent to land having hazardous combustible vegetation must follow the City of Placentia Vegetation Management Guidelines in force when plans are submitted. The fire code official can suspend vegetation management enforcement and require alternative measures in five listed circumstances.
324.1 Fuel Modification Requirements for New Construction. All new buildings to be built or installed in areas with or adjacent to land having hazardous combustible vegetation shall comply with the requirements in the edition of City of Placentia Vegetation Management Guidelines currently in use at the time of plan submittal. ... 326.1 Unusual circumstances. The fire code official may suspend enforcement of the vegetation management requirements and require reasonable alternative measures designed to advance the purpose of this code if determined that in any specific case that any of the following conditions exist: 1. Difficult terrain. 2. Danger of erosion. 3. Presence of plants included in any state and federal resources agencies, California Native Plant Society and county-approved list of wildlife, plants, rare, endangered and/or threatened species. 4. Stands or groves of trees or heritage trees. 5. Other unusual circumstances that make strict compliance with the clearance of vegetation provisions undesirable or impractical.
Full Breakdown
Placentia's fuel modification rule sits in the local amendments to the California Fire Code, § 18.04.050. Section 324.1, added by the City, ties new construction to the edition of the City of Placentia Vegetation Management Guidelines currently in use at the time of plan submittal. Section 324.1 itself prints no clearance distance in feet; the standard lives in the guidelines, so a plan is measured against the edition in use on the day it is submitted.
Section 304.1.3 requires the owner or occupant to cut down and remove weeds, grass, vines or other growth capable of being ignited and endangering property, and says vegetation clearance in urban-wildland interface areas follows the California Wildland-Urban Interface Code and the City's vegetation management guidelines. Section 325.1 separately authorizes the fire code official to have areas within 10 feet on each side of improved highways and private streets cleared of flammable vegetation.
Section 326.1 is the relief valve. The fire code official can suspend enforcement of the vegetation management requirements and require reasonable alternative measures if the case involves difficult terrain, danger of erosion, plants on a state, federal, California Native Plant Society or county-approved list of rare, endangered or threatened species, stands or groves of trees or heritage trees, or other unusual circumstances that make strict compliance with the clearance provisions undesirable or impractical. The fire code official is the chief of the Placentia fire and life safety department or a designee (§ 18.04.040).
Chapter 18.05 adopts the California Wildland-Urban Interface Code, 2025 Edition, as the Placentia Wildland-Urban Interface Code (§ 18.05.030). Its purpose clause (§ 18.05.020) covers construction and development in all Fire Hazard Severity Zones and aims to increase the ability of buildings to resist intrusion of flames or burning embers projected by a vegetation fire. The local enforcing agency enforces it (§ 18.05.050).
Violations & Fines
Violations of the Placentia Fire Code are an infraction or a misdemeanor under Section 113.4, with penalties assessed under the PFLSD adopted fee schedule and a separate offense for each day after due notice. Anyone who permits a fire or life safety hazard to exist on premises under their control is guilty of an infraction under Section 113.4.2. Work started without the required permit pays a penalty equal to 100% of the permit fee (§ 18.04.070).
