Orinda — Landscaping and Screening

Q: How tall can fences and retaining walls be on a residential lot?

Generally, fences may not exceed 6 ft ; within 5 ft of a street-facing property line an open-material fence ≤ 4 ft is required. Retaining walls are limited to 4 ft if within 10 ft of a property line or in a required yard setback, otherwise up to 8 ft — § 17.4.27(B) .

Q: How much of a parking lot must be landscaped in downtown Orinda?

Downtown rules require a 5‑ft perimeter planting strip around parking lots and 10% of the interior of parking lots must be landscaped; visible yards not used for parking have a 3‑ft planting strip within 50 ft of a street — § 17.8.10(A) .

Overview

This page summarizes what the City of Orinda's zoning ordinance (Title 17) requires for landscaping, screening, buffers, fences, retaining walls, and trees. It is focused only on what the zoning code mandates (landscape plans, landscape standards, fence/retaining wall limits, parking-lot planting, screening of mechanical equipment, and water-efficient landscaping) and points you to related development topics like Orinda Zoning, Orinda Development Standards, Orinda Parking, Orinda Design Review, Orinda Overlay Districts, Orinda ADUs and applicable state construction rules (the California Building Standards Code). All requirements below are taken from Title 17 (Zoning) provisions in the retrieved ordinance material and are cited to the controlling code sections.

Key city-level rules (plain summary of code requirements)

Landscape plans are required with most new residential or commercial applications and when an addition/remodel significantly affects existing landscaping — § 17.17.1.
A certificate of occupancy requires completion of required landscaping/irrigation and any riparian restoration unless the Zoning Administrator accepts security for delayed installation — § 17.17.2.
Landscape plans must be prepared by a qualified professional and inventory existing trees (species, height, diameter, condition) — § 17.17.3(A). Planting must avoid interference with sight lines, utilities, walkways and drainage — § 17.17.3(C).
The City enforces the State Model Water-Efficient Landscape Ordinance (MWELO) and adds local definitions and irrigation device standards — § 17.17.4.
Fences and retaining walls are regulated: fence height limits and measurement method, requirement for open materials near street frontages, retaining-wall height limits in setbacks, combined wall+fence height rules, and minimum horizontal separation rules — § 17.4.27.
Landscape structures (trellises, arbors, fountains, etc.) have setback, height and area limits — § 17.4.24.
Parking areas (nonresidential and multifamily) must submit a parking-area plan showing planting area, planting list, screening walls/fences, irrigation, lighting and drainage — § 17.16.16. Downtown parking has specific planting-strip and interior-landscape-area rules — § 17.8.10(A).
Exterior mechanical equipment and utility meters must be screened from off-site view; screening may be evergreen planting or architectural screen and may include perforated screening up to 50% open area — typically referenced in development standards for multifamily and nonresidential zones (examples: § 17.4.35 and related development sections).

District-by-district breakdown (how landscaping & screening rules apply)

Note: Title 17 organizes development standards by base districts (R, RM, RH, downtown districts) and overlays. Where district text references schedules (e.g., Schedule 17.4.2(B)) this page cites the landscaping/screening obligations in the sections actually retrieved; numeric setback tables themselves were not part of the retrieved snippets (see Information Gaps).

R districts (single-family residential; collectively referred to in the code as R Districts)

Purpose & typical uses: single-family residential neighborhoods; accessory uses and landscape structures allowed per zone rules. (General R-district context appears throughout Chapter 17; the code uses the term R Districts.)
Landscaping & screening specifics:
- Landscape plans are required with new residential construction and significant additions — § 17.17.1.
- Fences: maximum fence height generally 6 ft, but fences within 5 ft of a property line/right-of-way boundary with street frontage must be open material and may not exceed 4 ft; measurement method defined in § 17.4.27(A–B).
- Retaining walls: limited to 4 ft where within ten feet of any property line or in a required yard setback; otherwise up to 8 ft (with combined wall+fence measurement rules) — § 17.4.27(B)(2–3).
- Landscape structures (trellises, arbors) have a 5 ft minimum setback and height limits tied to whether they are inside setbacks (10 ft) or outside (15 ft) — § 17.4.24.

RM (Residential Medium) and RH (Residential High Density) districts

Purpose & typical uses: multi-unit development in RM and RH (RH specifically used for higher-density multifamily). RH development standards explicitly require landscaping and screening as part of design review.
Landscaping & screening specifics:
- All development in these districts must include a landscape plan complying with Chapter 17.17 and must provide “substantial landscape screening from off-site vantage points” and appropriate side/rear yard landscaping — § 17.4.35(F) (RH) and similar RM provisions.
- Mechanical equipment and meters must be screened from the public right-of-way; screening may be evergreen planting or architectural screens limited to 50% perforation — see § 17.4.35(G) and related mechanical equipment rules.
- Parking for multifamily projects must comply with Chapter 17.16 and parking-area planting and irrigation must be shown on the parking plan — § 17.4.35(B) and § 17.16.16.

Downtown districts (Downtown Core and other downtown zones)

Purpose & typical uses: commercial/mixed-use downtown development subject to downtown design guidelines and special planting/parking rules.
Landscaping & screening specifics:
- Visible yards not used for parking must have a 3‑ft planting strip adjoining interior property lines within 50 ft of a street; parking perimeter strips are 5 ft and 10% of parking interior must be landscaped — § 17.8.10(A).
- Fences in downtown are capped and the combined retaining wall + fence height rules apply (see § 17.8.10(D) referencing maximum fence heights).
- Projects in downtown that are subject to design review must meet the City of Orinda downtown design guidelines (design review link above) — § 17.30.10.

Overlay districts (e.g., -HD Overlay, SH‑Overlay)

Where overlays modify base-district development standards, the landscaping provisions of Section 17.17 still apply and the overlay-specific design review standards require primary landscaping to consist mainly of native species and supply substantial screening — see § 17.30.11(4) for senior housing/multifamily design review standards and § 17.4.34 for High Density overlay references.

Decision-relevant standards (quick-reference table)

Requirement / item	What the code requires	Code Reference
Landscape plan required with new construction / significant remodel	Applicant must submit a landscape plan prepared by a qualified professional, describing existing trees and how requirements will be met	§ 17.17.1, § 17.17.3(A)
Completion before occupancy	Landscaping/irrigation and riparian restoration must be installed before CO unless security accepted	§ 17.17.2
Water-efficient standards	City enforces State MWELO; local definitions and irrigation device rules added	§ 17.17.4
Fence height (residential yards)	Max 6 ft generally; within 5 ft of street-facing property line must be open material and ≤ 4 ft	§ 17.4.27(B)(1)
Retaining wall height	≤ 4 ft within 10 ft of property line or within required setback; ≤ 8 ft elsewhere; combined fence+wall rules apply	§ 17.4.27(B)(2–3)
Landscape structures	Min 5 ft setback; within setbacks ≤ 10 ft height, outside setbacks ≤ 15 ft height; area limits apply	§ 17.4.24
Parking-lot landscaping & screening	Parking plan must show planting areas, plant list, screening walls/fences, irrigation and drainage; downtown: 3 ft planting strip and 10% interior landscaping	§ 17.16.16, § 17.8.10(A)
Screening mechanical equipment	Equipment (AC units, transformers, meters) must be screened from off-site view; screening may be landscaping or architectural with up to 50% openings	§ 17.4.35(G) (and related standards)
Sports court fences in setbacks	Fences within a minimum setback: max 12 ft (sports courts exception)	§ 17.4.25(D)

Practical guidance & interpretation (plain-English synthesis)

If you propose new construction, an addition that materially changes landscaping, or a development subject to design review, expect to prepare a professional landscape plan that: inventories trees, shows irrigation and plant lists, meets the City’s fire‑safe plant list, implements MWELO water-efficiency measures, and shows any required riparian restoration if a watercourse is present (§ 17.17.1–4).
Front‑yard and corner‑side fences near the street are treated strictly: the code measures fence height from the lowest ground and requires open materials and accompanying landscaping if built within five feet of a street‑front property line (§ 17.4.27(A–B)). If you plan a solid, tall front fence, plan to show a landscape plan and be prepared for design review.
Retaining walls are limited when close to property lines or within setbacks; combined fence+wall heights and spacing rules mean that stacked walls/fences can easily breach the limits — design accordingly and show dimensions on your landscape or grading plans (§ 17.4.27(B)(2–4)).
For multifamily and nonresidential projects, screening of mechanical equipment, parking-lot planting, and pedestrian-focused planting in the downtown area are explicit code requirements that will be reviewed during planning or parking-plan review (§ 17.16.16, § 17.4.35, § 17.8.10).

Checklist (what you must supply / satisfy for a typical submittal)

A professional landscape plan prepared by a landscape designer/architect/qualified person per § 17.17.3(A) showing existing trees (species, height, diameter, condition).
Planting lists keyed to location, irrigation plan, and calculations for required planted/landscape area (parking plan when applicable) — § 17.16.16 and § 17.17.3.
Compliance with MWELO (State model) and the local water‑efficient landscape requirements in § 17.17.4.
Fire‑safe plant selection per the City of Orinda Landscape Guidelines as required by § 17.17.3(E) (verify current guideline document with the City).
Specification of screening for mechanical equipment and refuse enclosures consistent with § 17.4.35(G) and related screening requirements.
If the project includes fences or retaining walls, show measured heights from lowest ground, combined fence+wall heights, setbacks and spacing to demonstrate compliance with § 17.4.27.
For parking-lot work or new nonresidential / multifamily parking, submit the parking-area plan showing planting area, irrigation, screens and drainage per § 17.16.16.
If the property includes a watercourse, include riparian restoration plans in conformance with Chapter 18.04 (riparian rules noted in § 17.17.1).

Risks & Ambiguities

Issue	Why it matters	What to verify
Front/Corner-side fence near street	Fences within 5 ft of street-facing property line must be open material and ≤ 4 ft; otherwise you may need landscaping approval or design review — § 17.4.27(B)(1).	Verify exact property line vs. right-of-way edge, and whether a landscape plan is required under § 17.17.1.
Combined retaining wall + fence height	Stacking can exceed allowable heights and trigger redesign or variance — § 17.4.27(B)(3–4).	Measure from lowest existing grade, confirm horizontal separation, and verify whether design review will limit materials/height.
Heritage or protected trees	Tree inventory is required on plans (§ 17.17.3(A)), but specific heritage‑tree protections were not included in the retrieved landscaping sections.	Verify heritage tree rules and removal permit procedures with the City (see Chapter 17.24 reference in definitions). Verify with the jurisdiction.
Exact setback and district numeric standards	The code references schedules (e.g., Schedule 17.4.2(B)) for setbacks and other dimensional standards that affect where landscaping features may be located. Not all numeric schedules were in retrieved snippets.	Confirm the numeric setback and lot‑coverage standards in Schedule 17.4.2(B) and the base zone for your parcel. Verify with the jurisdiction.
Downtown guideline implementation	Downtown planting, screening and design guideline requirements can modify how strict the standards are for downtown development — § 17.30.10 and § 17.8.10.	Ask Planning staff which downtown design guidelines are in effect and whether your project triggers downtown design review.
MWELO applicability & thresholds	MWELO applies, but applicability thresholds and exceptions depend on project scope and local amendments — § 17.17.4.	Confirm whether your specific project meets MWELO thresholds (square footage of landscape area, etc.) and which local form/checklists are required.

Plain-English Summary

If you build or significantly alter a house, business, parking area, or multifamily project in Orinda you will almost always need a professional landscape plan that inventories trees, shows water-efficient irrigation, and screens mechanical equipment and parking; fences and retaining walls are capped and strictly measured, and special rules apply within five feet of street-facing property lines and in downtown zones. Verify property-specific setbacks and any heritage‑tree or riparian obligations with Planning. (Key code refs: § 17.17.1–4; § 17.4.27; § 17.16.16.)

Frequently asked questions

What triggers a required landscape plan in Orinda?

A landscape plan is required with applications for construction of a new residential or commercial structure and for additions/remodels that will significantly affect existing landscaping; the plan is also commonly required as a condition of design review — § 17.17.1.

Who must prepare the landscape plan?

The landscape plan must be prepared by a landscape designer, licensed landscape architect, or another qualified person and must describe all existing trees (species, height, diameter and condition) — § 17.17.3(A).

Do I need to finish landscaping before I get a certificate of occupancy?

Yes — the code requires installation of required landscaping and irrigation (and riparian restoration if applicable) before issuing a certificate of occupancy, unless the Zoning Administrator accepts a security deposit for delayed completion — § 17.17.2.

How tall can fences and retaining walls be on a residential lot?

Generally, fences may not exceed 6 ft; within 5 ft of a street-facing property line an open-material fence ≤ 4 ft is required. Retaining walls are limited to 4 ft if within 10 ft of a property line or in a required yard setback, otherwise up to 8 ft — § 17.4.27(B).

Are there special rules for sports court fencing or similar tall fences?

Yes — sports court fences have a specific allowance: the portion built within the minimum setback may be up to 12 ft in height (see § 17.4.25(D)), but other setback and design rules still apply.

What does the code say about screening HVAC units, meters and other equipment?

Exterior mechanical equipment and utility meters must be screened from view from off-site; screening can be heavy evergreen landscaping or architectural screening (perforations allowed up to 50% of surface area) — see screening specifications in the development standards (example: § 17.4.35(G)).

How much of a parking lot must be landscaped in downtown Orinda?

Downtown rules require a 5‑ft perimeter planting strip around parking lots and 10% of the interior of parking lots must be landscaped; visible yards not used for parking have a 3‑ft planting strip within 50 ft of a street — § 17.8.10(A).

Does Orinda require water‑efficient landscaping?

Yes — Orinda adopts the State Model Water‑Efficient Landscape Ordinance (MWELO) and adds local definitions/standards (see § 17.17.4). Check with Planning on the forms and thresholds that apply to your project.

Are there limits on combining fences and retaining walls?

Yes — the code measures a fence + retaining wall combination as a single structure for height limits unless the fence is set back from the retaining wall by half the required setback (but no more than 5 ft); minimum horizontal separation rules (4 ft) also apply — § 17.4.27(B)(3–4).

If my lot borders a creek, what landscaping is required?

If the property includes or borders a watercourse, riparian landscape restoration is required as part of a landscape plan and must comply with Chapter 18.04 (riparian standards) — § 17.17.1.
