Westlake Village Zoning, Planning & Building Codes

Last reviewed: July 3, 2026

Overview

Westlake Village’s zoning and planning rules are codified in the City’s planning and zoning articles (the municipal zoning chapters beginning with the 9.3–9.4 series) and implemented through zone maps, planned‑development procedures, and a small set of city specific plans. The code establishes the set of base zones (for example R-1, RPD, MHP, CPD, CR, BP, MU, PI, OS, SP) and delegates most project‑level numeric controls (setbacks, height, FAR, coverage, parking) to development‑standards chapters and to the Westlake North and other Specific Plans where they apply (§ 9.3.010) . Citywide procedures for zoning clearances, discretionary permits, notices and hearings are set out in the administrative chapters and application‑processing rules (§ 9.4.040; § 9.32.020–.030) .

How Westlake Village's code is organized

• The City organizes its zoning rules into numbered chapters (article and chapter-style sections) where each chapter addresses zones, standards, procedures, or special plan rules (for example the zoning district list in § 9.3.010 and the Westlake North Specific Plan in Chapter 9.24/§ 9.24.010). See § 9.3.010 for the district list and § 9.24.010 for the Westlake North Specific Plan overview .
• The code layers: (1) the base zoning map and zone definitions (§ 9.3.010; § 9.3.020) , (2) citywide development and design chapters (referenced throughout as Chapters 9.14–9.21 and related), and (3) specific plan chapters (notably Westlake North Specific Plan/§ 9.24.010 and the North Business Park Specific Plan referenced at § 9.44.010) .
• Administrative, hearing and appeal procedures (public notices, hearings, and notice of decision) are contained in the processing chapters (for example § 9.32.020–.050) .

(For quick navigation, see the city’s site menus: Westlake Village Zoning, Westlake Village Land Use, and the code’s development chapters such as Westlake Village Development Standards.)

Zoning district families

The municipal code explicitly establishes the following base zoning district families (all caps as used in the code):

• R-1 (Single‑Family Residential) — purpose: low‑density single family neighborhoods (§ 9.5.010) .
• RPD (Residential Planned Development) — allows clustered and planned residential projects subject to a Planned Development Permit (§ 9.6.010–.020) .
• MHP (Mobilehome Park) — rules for mobilehome park uses and conditional uses (§ 9.7.010–.020) .
• CPD (Commercial Planned Development), CR (Commercial Recreation), BP (Business Park), MU (Multiple Use), PI (Public/Institutional), OS (Open Space), and SP (Specific Plan) are also defined and used in the code; the full list and definitions appear in § 9.3.010 and related zone chapters (§ 9.08, § 9.10, § 9.11, § 9.12) .
• The MU (Multiple Use) zone is a holding/parent zone where a specific plan is required before detailed uses and standards are fixed (§ 9.11.010–.020) .

When you read a property’s zone on the Official Zoning Map, the code’s map‑rules and boundary rules control uncertain lines (§ 9.3.020–.030) .

Citywide development standards

• The code treats its listed standards as minimum requirements for public health and welfare and instructs that the more restrictive regulation controls if conflicts arise (for example conflicts with the Building Code) (§ 9.4.060–.070) .
• Chapters referenced as the central standards packages include the development standards chapter (commonly cited as Chapter 9.14), design standards (Chapter 9.15), landscaping (Chapter 9.16), hillside rules (Chapter 9.17), sign rules (Chapter 9.18), and off‑street parking and loading standards (Chapter 9.19) — these chapters are listed repeatedly as the applicable standards that projects must follow (§ 9.6.120; § 9.5.070; APPLICABLE REGULATIONS listings) .
  • For a practical primer on numeric controls and how the city organizes them, consult Westlake Village Development Standards.
• Typical items addressed by those chapters (and by specific plans where they apply) include: setbacks and yard standards, building height caps, lot coverage/maximum building coverage, floor‑area‑ratio (FAR) limits, building separation standards, and parking requirements — the code frequently delegates numeric values to either the zone chapter or to specific plans (for example the Westlake North Specific Plan sets FAR, height, coverage and setbacks for its planning areas) (§ 9.24.030–.040) .
  • Example (Specific Plan area): Planning Area D in the Westlake North Specific Plan has a maximum building coverage of 35%, a maximum FAR of 0.55, and a maximum building height of 47 feet (three stories, plus specific allowances) with tabled setbacks and separation standards in the Specific Plan text (see § 9.24.040 and the Planning Area D standards) .
• Parking standards are located in the off‑street parking chapter; required spaces and guest parking rules are implemented citywide but also vary in specific plans (see § 9.19 and the Westlake North Planning Area tables) — consult Westlake Village Parking and § 9.19 references in the Specific Plan (§ 9.24.040) .

Design, review and discretionary permits

• Design review and discretionary project review are managed through Planned Development Permits and the design/permitting chapters (the code requires planned development permits for RPD, MU developments, CPD projects where provided, and other situations) and design standards are explicitly applied during permit processing (§ 9.6.020; § 9.11.010–.020; Chapter 9.25 citations for permit procedures) .
  • For the city’s design review pathway and what triggers site‑level design submittals, see Westlake Village Design Review.
• Public notice, hearing procedures, and appeals are set out in the application processing chapter (notice rules for planned development, conditional use permits, and variances follow Government Code notice rules and are codified at § 9.32.020–.050) .
• The Specific Plans include additional plan‑level design requirements, mandatory landscape backbone plans, and CC&R obligations that feed into discretionary approvals (for example Westlake North requires master CC&Rs, backbone landscaping, and design/architectural controls; see § 9.24.110–.120) .

(When projects are ministerial and meet numeric standards they proceed differently — see Building Permit path below.)

Specific plans & overlays

• Westlake Village uses Specific Plans as a zoning overlay where a large site or a master redevelopment area requires unified standards. The Westlake North Specific Plan is codified at Chapter 9.24/§ 9.24.010 and is mapped as MU—SP No. 1 on the Official Zoning Map; the North Business Park Specific Plan is designated SP No. 2 (§ 9.44.010) .
• Specific Plans include their own tables for FAR, height, coverage and setbacks for each planning area and they can supersede or refine citywide chapter standards where stated; the Westlake North Specific Plan explicitly states that its standards implement the General Plan and must be complied with by subsequent permits (§ 9.24.020–.030) .
• Overlay topics (historic preservation, sign control, oak tree preservation, and other overlays) are administered by dedicated chapters referenced from the zone chapters and Specific Plan chapters; see the overlay menu at Westlake Village Overlay Districts and the Historic chapter references (see § 9.21 oak tree preservation and the code’s sign and historic listings) .

Building permits & review — the practical path

• Zoning clearance is required prior to most building permits: the Planning Director issues a zoning clearance certifying compliance with zoning before a building permit is issued, except for limited interior and minor exterior work on single‑family homes which the Building Department may allow without prior clearance (§ 9.4.040) .
• Application processing, ministerial vs discretionary review: the City follows Government Code timelines for application processing and explicitly distinguishes ministerial approvals from discretionary ones (see § 9.32.020). Public notices and hearings for discretionary permits are described in § 9.32.030–.050 for required noticing and hearing procedure .
• For ADUs and JADUs (state‑enabled accessory units), the code provides a ministerial pathway: ADU applications that meet the local ADU standards are ministerially approved by zoning clearance or by building permit only where the State criteria are met (the city’s ADU rules are codified in the development standards chapter and specifically implemented in the ADU subsection) (§ 9.14.070; see the ADU application/permit rules in the ADU subsection) . (See Westlake Village ADUs for city guidance.)
• Appeals and variances: the code provides Chapter 9.32 procedures for hearings and appeal notices and references the variance/exception chapters for the findings required (see Chapter 9.32 and the related variance chapters) (§ 9.32.020–.050) .

(For the building‑code technical review, the City defers to the California Building Standards Code in its building permitting and plan check processes.)

State housing law in Westlake Village

Westlake Village explicitly integrates State housing laws in several ways:

• ADUs / JADUs: The City allows ministerial ADU/JADU approvals consistent with Government Code § 65852.2; the local ADU rules implement ministerial zoning clearance or a building‑permit only path, prohibit denial for unrelated nonconforming conditions in many cases, and incorporate state procedural requirements (see the ADU application path and ministerial approval language in the ADU subsection; § 9.14.070 and the ADU provision text) . See also California ADU law and the city ADU page Westlake Village ADUs.
• Density bonus and related state programs: the code recognizes density bonus rights and states that granting a density bonus pursuant to State law does not, by itself, require a General Plan amendment or zoning change (see § 9.4.100) .
• Supportive and transitional housing: the City’s code contains a chapter to ensure consistency with State law for supportive housing and low‑barrier navigation centers so they are treated consistent with Government Code definitions (see § 9.45.010) .
• SB 9, rent control, and other specific State housing reforms: explicit SB 9 map/lot‑split provisions or local rent‑control ordinances were not located in the retrieved municipal text. Items that could not be confirmed from the materials provided are listed below in the Information Gaps section; verify with the City for up‑to‑date SB 9 and local rent control implementation.

How state rules interact in practice (short checklist)

• If an ADU meets the state eligibility criteria and the local numeric allowances in § 9.14.070, it can be ministerially approved by zoning clearance or building permit only (§ 9.14.070) .
• Density bonus is acknowledged in the code and does not in itself trigger a General Plan amendment (§ 9.4.100) .
• Supportive housing is required to be treated consistent with State definitions by local law (§ 9.45.010) .

Information Gaps (what the retrieved files did not confirm)

• The supplied excerpts do not show a discrete local SB 9 implementation chapter or specific local objective standards adopted to implement SB 9; current SB 9 practice and any city objective design standards for ministerial lot splits are Not found in retrieved materials — verify with the City planner or the latest municipal code online.
• No local rent‑control ordinance text was found in the retrieved municipal zoning excerpts — verify with the City’s housing or legal department for any separate rent regulation.
• The code references Chapter 9.14 (development standards) in many places; the searchable snippets show the ADU subsection and many cross‑references, but a complete table of all citywide setback/height/FAR defaults outside the Specific Plans was not present in the snippets retrieved — consult the full Chapter 9.14 in the municipal code for the comprehensive list.
