Westlake Village — Development Standards

Q: How is Floor Area Ratio (FAR) applied in Westlake North Planning Areas?

Each Planning Area has a net FAR cap (for example, Area A 0.50 , Area B 0.40 , Area D 0.55 , Area E 0.35 ). Apply the Planning Area FAR in § 9.24.030–.040 for Specific Plan parcels.

Q: What are the Hillside setback and ridgeline rules?

For sites in the Hillside Management Area, Chapter 9.17 requires visual analysis, minimizes grading, and generally prevents locating structures closer than 150 ft horizontal or 50 ft vertical to a prominent ridgeline unless findings justify a change. See § 9.17.040–.050 .

Q: Where do parking screening and berm requirements show up?

Parking screening, berm heights (commonly 42 in ), and parking location standards are required in the Specific Plan’s per‑area rules and by reference to the city’s off‑street parking chapter; see Planning Area rules (e.g., § 9.24.040 entries that require berm screening) and Chapter 9.19 for counts.

Overview

This page synthesizes what the Westlake Village municipal zoning and planning ordinance requires for development standards — setbacks, height, lot coverage, density/FAR, and closely related rules — where those rules live in the local code and how they vary by zone or planning area. It is grounded in the City’s Development Standards chapter and the Westlake North Specific Plan; citations to the controlling code sections are provided for every requirement cited. For rules on parking, design review, overlays, ADUs, or the state building code, see the linked topic pages called out below where those processes are handled in more detail.

Key local chapters used here: Chapter 9.14 (Development Standards), Chapter 9.24 (Westlake North Specific Plan — Planning Areas A–F), and Chapter 9.17 (Hillside Development Standards); each citation below shows the controlling section (§) and the ordinance source.

(First mention links — use these when you need the other topic pages: Westlake Village zoning & planning overview, Westlake Village Zoning, Westlake Village Parking, Westlake Village Design Review, Westlake Village Overlay Districts, Westlake Village ADUs, California Building Standards Code, Westlake Village Landscaping and Screening.)

How the code is structured (short)

Citywide baseline development standards live in Chapter 9.14 — Development Standards; the R‑1, RPD, CPD and similarly named zone rules are set out as subsections there (yards, heights, lot width/area, lot coverage, separations) (§ 9.14.010–.020).
The Westlake North Specific Plan establishes Planning Areas A through F with their own allowed uses, maximum FARs, lot coverage, heights and area-specific setbacks; those are in § 9.24.030–.040 and detailed per Planning Area in § 9.24.040 et seq.
Special standards for freeway-fronting development, cemetery perimeters and SCE easements are in § 9.24.100. Modifications to Specific Plan standards require Council action per § 9.24.110.

District-by-district breakdown (what applicants actually need to know)

Note: every district name below is bolded when first used and grounded to the § that defines its standards. For practical processing guidance, also check the city's Design Review and Parking rules referenced in the cited sections.

R-1 (Single-Family Residential) — basic residential standard set

Purpose and typical uses: conventional single-family residences; accessory guest houses and garages. Standards sit in § 9.14.020 (A).

Key dimensional standards (practical effect)

Maximum building height: 2 stories; 35 ft for main structures; 1 story; 18 ft for accessory structures/guest houses. (§ 9.14.020(A))
Front yard: 20 ft. (§ 9.14.020(A))
Rear yard (residences): 25 ft; accessory structures 5 ft. (§ 9.14.020(A))
Side yards: 10% of average lot width per interior side (max 10 ft) (street-side corner and reversed corner rules also defined). (§ 9.14.020(A))
Minimum lot area / width: 8,000 sq ft / 65 ft. (§ 9.14.020(A))
Lot coverage: Accessory buildings may not occupy more than 50% of the required rear yard; overall lot-coverage language is applied in project design and in other zones. (§ 9.14.020(A))

Practical note: setbacks are the "yard" minimums; on flag/irregular lots the Planning Director can determine yard layout (§ 9.14.020).

RPD (Residential Planned Development)

Purpose and typical uses: planned single‑family developments; rules largely mirror R-1 with project- or condition-specific modifications. Standards in § 9.14.020 (B).

Key points

Maximum height: 2 stories; 35 ft (main), 1 story; 18 ft (accessory). (§ 9.14.020(B))
Yards for single-family dwellings: same as R‑1 unless modified by conditions of approval. Multifamily yard rules: 20 ft from any public right-of-way. (§ 9.14.020(B))

Practical note: RPD projects typically proceed with a planned development permit and CC&Rs; minimum distances between buildings follow the same residential rules.

CPD (Commercial Planned Development) — citywide baseline

Purpose: commercial centers and mixed commercial uses; baseline provisions in § 9.14.020 (C); more detailed breakdown inside the Westlake North Specific Plan for Planning Areas C/E.

Typical dimensional standards (city baseline)

Maximum building height: 2 stories; 35 ft (subject to area-specific exceptions). (§ 9.14.020(C))
Setback schedules are area-dependent; Specific Plan Planning Areas supply the project-level setbacks (see Planning Area tables below). (§ 9.24.040)

Business Park / BP and Westlake North Specific Plan — Planning Areas A–F

The Westlake North Specific Plan (Chapter 9.24) splits the development site into Planning Areas A, B, C, D, E, F; each planning area has its own permitted uses, maximum FAR/building coverage, height caps and tailored setbacks. See § 9.24.030–.040 for the summary chart and per-area rules.

Summary table of the most decision‑relevant Specific Plan standards (extract)

Planning Area	Typical uses / purpose	Max FAR (net)	Max height (typ.)	Key setbacks / notes	Code Reference
Planning Area A	Hotel, accessory commercial, office	0.50 (net)	55 ft (hotel; 4 stories); other structures 35 ft	Loop Road setbacks; freeway frontage exceptions; see special freeway standard	§ 9.24.040(A)
Planning Area B	Office, restaurants, professional services	0.40 (net)	47 ft (office; 3 stories); restaurants 35 ft	Loop Road 20–30 ft parking/building setbacks; freeway frontage exceptions	§ 9.24.040(B)
Planning Area C	General retail, dining, services (shopping)	0.35 (net)	41 ft (towers up to 52 ft limited)	Russell Ranch, Ventura Fwy, parking setbacks; large anchor rules	§ 9.24.040(C)
Planning Area D (BP)	Office, business park, R&D, light industrial	0.55 (net)	47 ft (3 stories)	Loop Road, residential/cemetery buffers; large building-to-residential separations (140 ft in some cases)	§ 9.24.040(D)
Planning Area E	Retail and neighborhood commercial	0.35 (net)	35 ft (2 stories)	Lindero Canyon & Thousand Oaks Blvd front setbacks 10–30 ft; residential interface 40 ft	§ 9.24.040(E)
Planning Area F	Residential (multi-family)	Density cap: 14.1 du/ac; total ~250 DUs	35 ft	Specific multi-family setbacks; spacing and parking standards tied to PD approval	§ 9.24.030 / § 9.24.040(F)

Practical interpretation: the Specific Plan gives project-level FAR caps and maximum heights by area (A–F). If your site sits in the Specific Plan area, the Specific Plan numbers control; for parcels elsewhere in the city, the zone-specific rules in Chapter 9.14 apply.

Freeway frontage, SCE easement and cemetery perimeter (special-area controls)

Freeway-fronting standards: parking and buildings adjacent to the Ventura Freeway have much larger required setbacks — e.g., parking setback 30 ft; first-floor building setback 100 ft; second floor 120 ft; third floor 140 ft (measured from the freeway). Building orientation and facade modulation rules also apply. See § 9.24.100(B)(1).
SCE Easement Area: landscaping and access, with possible 0 ft setbacks for parking depending on the subarea; subject to SCE approval. (§ 9.24.100(A) and per-area setbacks in § 9.24.040).
Cemetery perimeter: decorative masonry/wrought‑iron wall and buffer required along the interface with the cemetery; see § 9.24.100(C).

Hillside Development Area (Hillside Management Area)

If a lot is in the Hillside Management Area, the Hillside Development Standards (Chapter 9.17) add site-planning and view-preservation limits, slope-specific setbacks, ridgeline protection, and grading constraints; those rules can require additional setbacks from ridgelines (e.g., 150 ft horizontally or 50 ft vertically criteria unless modified) and visual analyses at application. See § 9.17.010–.050.

Fences, walls and screening

Fences and walls have maximum heights and materials rules (front-yard height limits of 42 in in residential setbacks; up to 6 ft walls where abutting residential/commercial edges require decorative walls and landscaping). See § 9.14.050.

Quick-code checklist (what an applicant must satisfy)

Determine the parcel’s zone or Planning Area and apply that district’s height, setback, lot area/width, and lot‑coverage/FAR rules (Chapter 9.14 for traditional zones; § 9.24.030–.040 for Westlake North Specific Plan).
For parcels in the Specific Plan, confirm applicable FAR and max building height from the Planning Area table and apply the area-specific setbacks (e.g., Freeway frontage – § 9.24.100).
Verify interface buffers: cemetery, SCE easement, and adjacent residential areas have specific setbacks and screening obligations (§ 9.24.100 and per-area rules).
Meet off‑street parking requirements in Chapter 9.19 and site screening/berm requirements where specified (loop road, Lindero Canyon/Thousand Oaks, freeway edges). See Westlake Village Parking.
Prepare landscape plans per the design review requirements and the Specific Plan backbone landscaping; landscape and berms are required for parking screening in many locations. See Westlake Village Landscaping and Screening.
If in a Hillside Management Area, include visual analyses, grading balance, and ridgeline siting documentation per Chapter 9.17.
For any proposed deviations from Specific Plan standards, be prepared for a public hearing and Council action under § 9.24.110 (modification of standards).
Confirm whether design review is required and route materials per the City’s Design Review process.

Risks & Ambiguities

Issue	Why it matters	What to verify
Freeway frontage setback math	Freeway-fronting setbacks are much larger and measured to floors (100/120/140 ft) — they can reduce developable area dramatically	Confirm whether your lot edge qualifies as "freeway frontage" and use § 9.24.100(B)(1) distances in site layout.
Which standard controls: Chapter 9.14 vs Specific Plan	Specific Plan numbers (FAR, height) override or supplement citywide zone rules within the Specific Plan area	Locate parcel on the Specific Plan Exhibit and apply § 9.24.030–.040 first, then Chapter 9.14 where not superseded.
Hillside/ridgeline setbacks	Hillside rules can impose cross‑section setbacks (horizontal/vertical) that override normal yards	If in the Hillside Management Area, follow Chapter 9.17 requirements and prepare required visual/graded analyses.
SCE easement and third‑party approvals	SCE approval may alter allowable landscape or setback treatments adjacent to their easement	Confirm SCE easement limits and written SCE approvals as required by § 9.24.100(A).
Modification path / uncertainty for non-standard designs	Planned Development Permits and Council modifications are discretionary; timing and conditions are uncertain	If your design needs relief, expect a public hearing for modification under § 9.24.110; prepare findings and community outreach.
ADU-specific setbacks/limits	Local code references accessory structures but state ADU law may preempt local limits	Local ADU specifics were not fully found in the retrieved materials; verify ADU treatment with the City and California ADU law. Not found in retrieved materials; consult California ADU law.

Plain-English Summary

Westlake Village’s development standards are a mix of citywide yard/height rules (Chapter 9.14) and area-by-area caps and setbacks inside the Westlake North Specific Plan (Planning Areas A–F in Chapter 9.24). Expect standard single‑family limits (R‑1: 35 ft height, 20 ft front setback, defined side/rear yards) and larger, often stricter setbacks and FAR/height caps for commercial and freeway‑facing parcels; hillside and easement rules can impose additional constraints. Always check the parcel’s zone or Planning Area first — those numbers control.

Frequently asked questions

What can I build on an R-1 lot in Westlake Village?

You may build a single‑family home and customary accessory structures; the R‑1 district sets a 2‑story / 35 ft main structure limit, 20 ft front yard, 25 ft rear yard for residences, side yards equal to 10% of average lot width (max 10 ft), and minimum lot size 8,000 sq ft (65 ft width). See § 9.14.020(A).

What are Westlake Village setback requirements for freeway‑facing buildings?

In the Westlake North Specific Plan, freeway frontage setbacks are oversized: parking setbacks 30 ft; building setbacks of 100 ft (1st floor), 120 ft (2nd), 140 ft (3rd+) from the freeway; additional orientation and facade modulation rules apply. See § 9.24.100(B).

How is Floor Area Ratio (FAR) applied in Westlake North Planning Areas?

Each Planning Area has a net FAR cap (for example, Area A 0.50, Area B 0.40, Area D 0.55, Area E 0.35). Apply the Planning Area FAR in § 9.24.030–.040 for Specific Plan parcels.

Do I need design review for a new building?

Design review requirements are applied as part of project processing and referenced throughout the Specific Plan; consult the City’s Design Review page and the applicable Specific Plan sections; projects in the Specific Plan area will be reviewed under the plan’s architectural standards in § 9.24.030–.040.

What special rules apply next to the cemetery or the SCE easement?

A decorative masonry/wrought‑iron wall and landscape buffer are required along the cemetery interface, and SCE easement boundaries require specific landscaping/board approvals; see § 9.24.100(C) and § 9.24.100(A).

Can the Specific Plan standards be changed for my project?

Yes. The Council can modify Specific Plan development standards after a noticed public hearing if findings in § 9.24.110 are met (demonstrating the modifications still meet the plan intent, aren’t detrimental, etc.). Expect discretionary review.

What are the Hillside setback and ridgeline rules?

For sites in the Hillside Management Area, Chapter 9.17 requires visual analysis, minimizes grading, and generally prevents locating structures closer than 150 ft horizontal or 50 ft vertical to a prominent ridgeline unless findings justify a change. See § 9.17.040–.050.

Where do parking screening and berm requirements show up?

Parking screening, berm heights (commonly 42 in), and parking location standards are required in the Specific Plan’s per‑area rules and by reference to the city’s off‑street parking chapter; see Planning Area rules (e.g., § 9.24.040 entries that require berm screening) and Chapter 9.19 for counts.

Are there lot‑coverage limits and building separation requirements?

Yes — the Specific Plan and residential chapters set lot‑coverage and minimum building separations (the Specific Plan often uses 35% building coverage in commercial areas and 70 ft minimum building separation in many Planning Areas). Check § 9.24.040 and § 9.14.020 for the precise standard applying to your parcel.

How do ADU rules interact with these development standards?

Local ADU specifics were not present in the retrieved ordinance excerpts. State ADU law can preempt stricter local rules on setback/coverage for ADUs; verify with the City and consult state ADU statutes. Not found in retrieved materials; consult California ADU law.
