Summary
Lancaster requires any landscape design plan for a project in a fire-prone area to build in defensible space around buildings under Municipal Code Section 8.50.090, tying the local landscaping ordinance directly to the state's defensible-space law, Public Resources Code Section 4291(a) and (b). Plans must avoid fire-prone plants and flammable mulch and follow the local fire authority's fuel modification guidelines.
A landscape design plan for projects in fire-prone areas shall address fire safety and prevention. A defensible space or zone around a building or structure is required per Public Resources Code Section 4291(a) and (b). Avoid fire-prone plant materials and highly flammable mulches. Refer to the local fuel modification plan guidelines.

Full Breakdown
Lancaster folds wildfire risk directly into its landscape ordinance rather than carrying a separate wildfire-zone chapter. 50, the city's water-efficient landscape ordinance adopted under Ordinance No. 090. Subsection (A)(1)(j) of that section singles out fire-prone areas: the plan must address fire safety and prevention and build in a defensible space or zone around each building or structure as required by Public Resources Code Section 4291(a) and (b), the state's defensible-space clearance law. 020 as the guidelines a local fire authority issues to assist residents and businesses developing land or building structures within a fire hazard severity zone.
090(A)(1)(a) reinforce this by directing applicants to choose plants from the city's approved list based on local fuel modification plan guidelines. Every sheet of the landscape design plan must carry a licensed landscape architect's or landscape contractor's stamp and signature certifying compliance with the chapter, and city development services staff reviews the plan as part of the permit, plan check, or design review process before construction can proceed.
Violations & Fines
Lancaster enforces Chapter 8.50 through the same permit, plan check, and design review process that governs any landscaping project; a design that omits the required defensible space or ignores the fuel modification plan guide can be rejected or held up at plan check by development services, and work built without an approved landscape documentation package is subject to the code's general penalty and administrative citation provisions in Chapters 1.12 and 1.16.
