Thousand Oaks — Landscaping and Screening

Last reviewed: July 2, 2026

Overview

This page summarizes what the Thousand Oaks Municipal Code (Title 9 / zoning chapters) requires about landscaping, screening, buffers, fences/walls, and trees for development and subdivision projects inside the City. It pulls the controlling code provisions (the most-used rules are about required screening where non‑residential uses abut residential zones, maximum fence/wall heights, planting-strip widths adjacent to parking and streets, and protected tree/site plan requirements) and cites the exact local sections. Always verify site‑specific application with the Community Development Department.

For the City overview and zoning map start points see the Thousand Oaks zoning & planning overview. When this page refers to parking, design review, overlays, development standards, ADUs, or the state building code it links to the City pages you’ll need for next steps.

Key citywide rules (short list)

• Fences/walls/hedges along side and rear lot lines are generally limited to 6 ft; front yard fences are limited to 3 ft unless otherwise allowed. Exceptions exist for noise attenuation and special subdivision walls — see § 9-4.2805(i) and § 9-3.1025.
• Where a non‑residential parking or circulation area abuts property in an R zone, a 6 ft solid decorative wall or an evergreen hedge (6 ft) is required to screen view/light; multiple zone articles repeat this rule (examples: C‑3 § 9-4.1404(c), M‑2 § 9-4.1704(b), M‑1 § 9-4.1605(b), P‑L § 9-4.3203(b)).
• Planting strips and parking-lot landscaping are regulated (typical planter/strip widths and minimum landscaped percentages appear in the parking/landscaping rules used by the Community Development Director); some zone-specific planting strip widths (for example C‑2 and C2/AM) are spelled out in the ordinance text. See cited passages below.

District-by-district requirements (purpose, common uses, key landscaping/screening standards, where it applies)

Note: bolded district names and bolded numeric standards make it quick to scan. Each requirement below is tied to the Municipal Code § that contains it.

R zones (single‑family & multi‑family: R-1, R-2, R-3, R-P-D, R‑P‑D SP, etc.)

• Purpose & typical uses: residential; preserve neighborhood scale and open space (rules and objective design standards for residential development are in Article 22 and the zone articles). See objective design standards for residential development in § 9-4.2205.
• Key landscaping/tree rules:
  • Street trees / parkway trees: subdivisions must include street tree planting (one tree per lot, two for corner lots) selected from the Forestry Master Plan; tree plans must be prepared by a registered landscape architect and approved prior to installation — § 9-3.1006.
  • Protected tree/site plan: applications for many residential permits must show location of protected trees (and arborist memo) and address replacement if removal is required; see Oak Tree and Landmark tree chapters (definitions: § 9-4.4202 and § 9-4.4302) and the protected-tree submittal requirements in the development application text. The code requires the site plan to include protected trees on or within 15 ft of the property and an arborist memo if trees will be impacted — see the site and tree plan requirements text (tree provisions referenced through protected tree sections).
• Fences/walls: front‑yard fences generally limited to 3 ft; side/rear fences/walls/hedges permitted up to 6 ft (measurement rules and corner‑lot sight‑distance rules apply) — § 9-4.2805(i).
• Where it applies: all properties in the City with R zoning; development-level design standards are in Article 22 and the applicable R zone article (verify the exact underlying R designation on your parcel).

C-1 — Neighborhood Shopping Center Zone

• Purpose & typical uses: planned neighborhood shopping centers (supermarket, drugstore and convenience retail) intended to be compatible with surrounding residences — § 9-4.1200.
• Key landscaping/screening standards:
  • When parking/circulation abuts an R zone, a 6 ft solid fence/wall or evergreen hedge (6 ft) must be provided — see § 9-4.1404(h) and related development permit conditions for commercial zones; C‑1 development requirements mirror this same approach.
  • Trees in parkway/curbside areas as approved by the Landscape Supervisor are required in commercial frontage conditions — see the C‑zone development permit text.
• Where it applies: sites zoned C‑1 (Neighborhood Shopping Center).

C-2 / C2‑AM — Community Commercial / Automotive‑oriented

• Purpose & typical uses: larger convenience and community commercial uses; the ordinance includes specific planting-strip dimensions for these zones.
• Key landscaping/screening standards:
  • Front landscape strip widths: C‑2 front = 20 ft; C2/AM front = 14 ft; in all other locations the code prescribes 10 ft (C‑2) or 4 ft (C2/AM) planting strips as the base requirement where parking or circulation abuts streets; the text is explicit in the parking/landscaping provisions. See the parking/landscaping paragraph that spells out the C‑2 / C2‑AM exceptions.
  • Standard screening where parking abuts residential property: 6 ft solid wall or evergreen hedge (see other zone examples below that repeat the same requirement).

C-3 — Community Shopping / Commercial

• Purpose & typical uses: larger community retail/service uses where the code requires design compatibility and screening to adjacent residential areas — § 9-4.1404.
• Key landscaping/screening standards:
  • If parking/circulation area abuts an R zone a solid fence or wall 6 ft high or evergreen hedge 6 ft high is required (§ 9-4.1404(c)).
  • Where parking or circulation abuts a public street and the parcel across is residential, provide a planting strip (example: 1.5 ft for C‑3 per the same subsection) with a minimum planting height — § 9-4.1404(h).

C-4 / C-O (regional, office)

• Purpose & typical uses: C‑4 (regional commercial) and C‑O (commercial‑office) have similar requirements for parking landscaping and screening; the C‑O article requires a minimum landscaped percentage of parking area and planting strip widths along adjacent streets — see § 9-4.1109 (C‑O) and the C‑4 development permit subsections.

M-1 / M-2 (Industrial / Light Manufacturing)

• Purpose & typical uses: industrial/park/manufacturing uses with stricter interface standards to protect adjacent residential areas.
• Key landscaping/screening standards:
  • If parking/circulation abuts an R zone there must be a 6 ft solid decorative wall or evergreen hedge 6 ft — § 9-4.1704(b) (M‑2) and § 9-4.1605(b) (M‑1) include this requirement.
  • A 10 ft planting strip is required along property lines adjacent to streets when the property opposite is residential or commercial, with planting maintained at ≤ 2.5 ft (except trees) — § 9-4.1704(e) (M‑2).

P‑L (Public, Quasi‑Public, Institutional Lands & Facilities)

• Purpose & typical uses: public/quasi‑public and institutional sites (schools, hospitals, parks). Landscape, parking, and screening requirements are tailored to fit institutional needs — see § 9-4.3201 – 9-4.3203.
• Key landscaping/screening standard:
  • Where P‑L property abuts an R zone a solid wall 6 ft high to substantially bar view/light is required (waiver possible where topography warrants) — § 9-4.3203(b).

Hillside Planned Development — H‑P‑D (overlay)

• Purpose & typical rules: hillside development must preserve natural terrain — the article requires retention of trees/vegetation and usually requires additional landscape and screening to maintain scenic and safety objectives — see § 9-4.3100 (H‑P‑D purpose and policy).

Decision‑relevant standards table

Notes:

• Many different zone articles repeat the same interface/screening rule (the 6 ft screen between commercial/industrial parking and residential), so expect it to apply whenever a parking/circulation area sits adjacent to residential zoning. See the multiple citations in the table.
• Some parking landscaping paragraphs appear across related code excerpts but the consolidated single‑section number for the entire “parking / landscaping” block was not always shown in the excerpts I received; verify the complete block and its section number with the Community Development Department or the official online code if you need the exact single-section citation for an item like the 10% interior landscaping rule. The ordinance excerpts do contain the 10% requirement in the parking paragraphs I reviewed.

Practical guidance for applicants (plain English, applied)

• If your site is commercial/industrial and its parking/circulation area touches a residentially zoned lot line, budget for a 6 ft solid decorative wall or an evergreen hedge that will grow to 6 ft. Multiple zone articles require this screening (examples: § 9-4.1404(c), § 9-4.1704(b), § 9-4.1605(b), § 9-4.3203(b)).
• For any new parking lot expect to show a landscape plan with perimeter planter strips and interior landscaping. Many parking rules require planter curbs, permanent irrigation, and tree species that avoid damaging roots in pavement — see parking/landscaping text. If you must meet a specific C‑zone requirement (e.g., C‑2 front 20 ft strip), follow that zone's numeric requirement.
• If you propose a taller wall (for noise), the code allows up to 9 ft in special circumstances but the Director (or Commission) must find the criteria are satisfied, including terracing and sight‑distance safety — see § 9-4.2805(i)(2). Expect design detail requirements (materials, terracing, architectural elements) when proposing >6 ft walls.
• For subdivisions and projects that will disturb trees, include the protected‑tree inventory, arborist memo, and any replacement planting plan as part of the initial submittal — the code requires the site plan to show protected trees on or within 15 ft of the site and arborist recommendations; replacement rules cross‑reference the oak and landmark tree chapters.
• If you’re working on an ADU or a residential design package, expect the City to look for landscaping that screens service/mechanical equipment and meters from public view; check the ADU objective standards for privacy glazing and screening requirements as well. See the ADU objective standards excerpt and the equipment‑screening rules in multifamily/residential subsections.

(If you are preparing drawings, reference the City’s landscape design/planting standards and the Forestry Master Plan for species lists and irrigation requirements when preparing planting schedules — these are referenced in the code but the full plant palettes live in those referenced standards.)

Checklist

• Identify zoning on the parcel (R‑zone, C‑zone, M‑zone, P‑L, overlay) — verify parcel zoning with City GIS. Verify with the jurisdiction.
• Show all protected trees on or within 15 ft of the property on the site plan and include an arborist memo if trees are affected — see protected tree provisions and application requirements § 9-4.4202 / § 9-4.4302 and the arborist/site plan text.
• Provide a landscape plan showing: planting strips adjacent to streets (per zone), interior parking landscaping, permanent irrigation, planter curbs, species/size/spacing and deep‑root watering or root guards where adjacent to hardscape — see the parking/landscaping requirements excerpt.
• If parking/circulation abuts an R zone, show a 6 ft solid wall or evergreen hedge (design/detail notes) on the plot plan — cite the applicable zone development permit condition (e.g., § 9-4.1404(c), § 9-4.1704(b)).
• If your proposal includes a fence or wall taller than 6 ft (or a noise wall), include sound‑attenuation justification, terraced wall details, color/material palette, and sight‑distance analysis for the Traffic Engineer and Community Development Director per § 9-4.2805(i)(2).
• For subdivisions, show required subdivision perimeter walls and street trees per § 9-3.1025 and § 9-3.1006 and complete as conditions of map approval.
• If your project triggers Design Review or modifications, consult Thousand Oaks Design Review and reference Article 18 objective design standards § 9-4.1800 et seq. — design review will look closely at screening and landscape treatments.

Risks & Ambiguities

Plain‑English summary

Thousand Oaks requires thoughtful landscaping and solid screening where non‑residential activity (especially parking and service areas) is next to homes: plan on a 6‑foot solid wall or hedge, street trees in parkways, planting strips at property lines (zone‑dependent widths), interior parking landscaping and permanent irrigation, and special treatments for hillside and subdivision projects. Fences are normally limited to 6 ft at side/rear and 3 ft in front; taller noise walls require approval and design detail. See the cited code sections when preparing your landscape plan.
