Fresno County — Landscaping and Screening

Q: How high can I build a fence in the front yard of an R‑1 lot in unincorporated Fresno County?

Front‑yard fences are generally limited to 4 ft ; some R‑1 subzones allow 7 ft front fences when not in a corner cut‑off area and when the fence is ≥70% open (vertical openings). See § 822.3.050 and check the R‑1 subzone for exact exceptions.

Overview

This page summarizes what the Fresno County Zoning Ordinance requires for landscaping and screening in the county’s unincorporated areas. Requirements are found primarily in the Property Development and Use Standards (Chapter 822.3 — Screening, Setbacks, Fences) and the Landscaping Standards (Chapter 826.3) of the Fresno County Zoning Ordinance; check the county-wide zoning overview for context and maps. See guidance on how landscaping ties into parking, development standards, and design review when preparing submittals. Always confirm whether an overlay district or other special plan applies to your parcel and whether the project interacts with ADU rules or the California Building Standards Code.

Key Fresno County rules (plain list)

Screening required between non‑residential and residential zones: an opaque plant screen plus a minimum 6 ft solid masonry wall along parcel boundaries when a commercial, industrial, or institutional development adjoins a residential zone — see § 822.3.090.
Screening of mechanical equipment, loading docks, refuse areas, and outdoor storage: devices and storage must be screened from public view and adjacent residences with materials compatible with on‑site architecture; outdoor storage must be behind a 6–8 ft sight‑obscuring wall or fence and gates — see § 822.3.090.B–C.
Designated large commercial/industrial developments must provide landscape buffers plus walls sized to building footprint thresholds (examples: 5 ft buffer + 6 ft wall for >25,000 sf commercial; larger buffers/walls at 50,000 sf and 100,000 sf thresholds) — see § 822.3.090.E–F.
Landscaping must follow water‑efficient rules (MWELO) for planting design, installation and maintenance (§ 826.3.010) and commercial/industrial/warehousing developments must follow species, spacing, and shade targets (trees 24‑inch box minimum, trees at no greater than 40 ft on center; parking lots >50,000 sf must achieve 35% shade at maturity or equivalent PV shade structures) — see § 826.3.010–020.
Fences/walls/hedges limits (front yards, corner cut‑offs, maximum heights and exceptions such as 7 ft allowances when open on ≥70% vertical surface) and gates/Knox box access are in § 822.3.050.
Walls constructed along a street as a district boundary must be set back 10 ft with that space landscaped and maintained (measurement and exceptions in § 822.3.100 / Setback Regulations).

District-by-district breakdown (unincorporated Fresno County)

Note: each district name is bolded. For full zone maps and listing of allowed uses consult the Fresno County Zoning tables. Verify parcel‑specific rules with the County.

R-1 (single-family residential) — (see Chapter 810.2 Residential Zones)

Purpose / Typical uses: single‑family detached dwellings and accessory uses.
Landscaping / screening focus: residential front yards and street‑facing setbacks are expected to be landscaped; fences/walls in required front yards are limited in height (4 ft typical) with exceptions for open‑work 7 ft fences in some R‑1 subzones if ≥70% open (see § 822.3.050).
Key dimensional standards: common table minimum front setback 35 ft, side 20 ft (varies by subzone); landscaping note in zone tables refers to Chapter 826.3.
Where it applies: county residential neighborhoods and unincorporated subdivisions mapped to R‑1. Verify specific subzone (R‑1‑A, R‑1‑B, etc.) for fence exceptions.

R-2, R-3, R-4 (multi‑family residential) — (see Chapter 810.2 / multifamily tables)

Purpose / Typical uses: duplexes and multi‑unit housing.
Landscaping / screening focus: multi‑family projects must follow Article 3 landscaping standards (Section 826.3) and screening rules for adjacent non‑residential uses (§ 822.3.090).
Key dimensional standards: setbacks and heights vary by zone (typical front 35 ft, side 20 ft; maximum heights differ by zone). See the zone tables in Article 2.

C-2, C-3, RCC, R‑P (commercial / community commercial) — (see Chapter 812.2 Commercial Zones)

Purpose / Typical uses: retail, services, community commercial uses.
Landscaping / screening focus: when abutting residential zones, commercial developments must install opaque screening and walls per § 822.3.090.A; designated larger commercial projects must meet the frontage buffer and wall height thresholds in § 822.3.090.E and also meet Chapter 826.3 for planting.
Key dimensional standards: front setbacks vary (some commercial front setbacks as low as 10 ft with landscaping requirements). See zone tables for exact numbers.

Designated Commercial Development (per Table 2‑6) — (special designations inside Article 2)

Purpose / Typical uses: larger retail/warehouse campus developments that trigger scale‑based buffering standards.
Landscaping / screening focus: thresholds trigger specific buffer widths and wall heights — e.g., >25,000 sf = 5 ft buffer + 6 ft wall; 50,000+ sf = 10 ft buffer + 6 ft block wall; 100,000+ sf = 20 ft buffer + 7 ft wall. All landscaping must meet § 826.3.020.

Designated Industrial / Warehousing Development (per Table 2‑8)

Purpose / Typical uses: warehousing, distribution and industrial facilities.
Landscaping / screening focus: scale drives buffer/wall requirements — e.g., <50,000 sf: 5 ft buffer + 7 ft wall; 50,000+ sf: 10 ft buffer + 7 ft block wall; 400,000+ sf: 20 ft buffer + 10 ft block wall. Landscaping must comply with § 826.3.020.

R‑C, R‑E (Special Purpose / Rural residential zones) — (see Chapter 816.2)

Purpose / Typical uses: large‑lot residential, caretaker homes, low density rural uses.
Landscaping / screening focus: fences and walls in rear/side yards up to 7 ft are typical; front yard fence heights are restricted per § 822.3.050. Landscaping references point back to Chapter 826.3.

(If your parcel is in a specific Specific Plan area or the Millerton or other plan, there are additional localized landscaping provisions — see the applicable specific plan chapter.)

Practical guidance & interpretation (what applicants should do)

Provide a landscaping plan that explicitly cites compliance with § 826.3.010 (MWELO) and the applicable items of § 826.3.020 for commercial/industrial sites (tree species, box size, spacing, and parking shade calculations).
For any non‑residential use abutting residential zones, show the location/type of the required 6 ft opaque wall and the planting at the parcel boundary per § 822.3.090.A; specify whether plantings will provide the opaque screen or if masonry wall will do both.
If proposing outdoor storage, detail the wall/fence height (6–8 ft), gate type, and demonstrate stored materials will remain below the fence top and loading operations occur within the fenced area per § 822.3.090.C.
When a project crosses the scale thresholds in § 822.3.090.E–F (designated commercial/industrial), include the buffer width and wall height shown in the code and label adjacent “sensitive receptors” on plans.
Expect Director review/approval for the architectural compatibility of screening treatments and for exceptions (see Fresno County Design Review).

Checklist

Confirm base zone and any overlay/specific‑plan rules for your parcel (verify with County).
Prepare a planting plan meeting MWELO and show plant palette, irrigation strategy, and maintenance notes (§ 826.3.010).
For commercial/industrial sites, show tree species, min 24‑inch box, spacing ≤ 40 ft, or PV shade alternative and 35% shade calc if >50,000 sf parking (§ 826.3.020.B).
If adjacent to residential zoning, show opaque screen + 6 ft masonry wall location/elevations (§ 822.3.090.A).
If outdoor storage or loading is proposed, provide enclosure details: 6–8 ft wall/fence, gates, materials kept below fence, internal circulation (§ 822.3.090.C).
If project size meets thresholds in § 822.3.090.E/F, show appropriate buffer widths and wall heights on plans.
Ensure refuse/recycling enclosures are screened per § 822.3.120 and located per access requirements.
Confirm proposed fences/walls comply with § 822.3.050, corner cut‑offs, and emergency access (Knox box).

Risks & Ambiguities

Issue	Why it matters	What to verify
Which zone/subzone applies	Landscaping/fence exceptions differ by subzone (e.g., R‑1 subtypes)	Verify the parcel’s official zoning label and subzone; check Article 2 tables. Verify with the County.
“Designated” commercial/industrial thresholds	Buffer/wall obligations change with building area; missing these can trigger rework	Confirm whether the project is subject to Table 2‑6/Table 2‑8 designations and measure gross floor area precisely. See § 822.3.090.E–F.
Trade‑offs: planting vs. masonry for opacity	County allows plant material but requires opacity — plant survival and maturity affect screening effectiveness	Show species, sizes (min 24‑inch box for many commercial trees), and maintenance plan; include interim screening if plants won’t attain opacity quickly. § 826.3.020.
Setback vs. wall placement on street boundary	Walls along streets must be set back 10 ft and landscaped — may reduce usable frontage	Confirm in plan whether the district boundary equals a street; show the 10 ft landscape strip and plantings. § 822.3.090.
Director’s discretion	“Architecturally compatible” and screening approvals are discretionary	Expect Director review/conditions; contact staff early or request a pre‑application meeting. § 822.3.090.B.
ADUs and accessory structures	ADU landscaping or fence allowances may differ from primary development standards	Verify ADU-specific rules and state ADU law; parcel‑specific exceptions may apply. Verify with County and review California ADU law. Not found in retrieved materials for landscaping specifics to ADUs.

Plain-English Summary

In unincorporated Fresno County you must show water‑efficient landscaping that meets state MWELO standards and, whenever a non‑residential use touches a residential zone, provide an opaque screen plus at least a 6‑foot masonry wall; larger commercial or industrial projects require wider planted buffers and taller walls at set size thresholds. Trees for commercial sites must be drought tolerant, 24‑inch box minimum, spaced roughly every 40 ft, and parking lots larger than 50,000 sf must reach 35% shade (or provide equivalent PV shade) — verify all details and Director approvals with County planning staff.

Frequently asked questions

What does Fresno County require when a commercial site borders a residential zone?

When a commercial, industrial, or institutional development adjoins a residential zone Fresno County requires an opaque screen consisting of plant material and a minimum 6 ft solid masonry wall along the shared parcel boundary; walls must be landscaped/treated on both sides and height limits must still comply with fence/wall rules. See § 822.3.090.A.

How high can I build a fence in the front yard of an R‑1 lot in unincorporated Fresno County?

Front‑yard fences are generally limited to 4 ft; some R‑1 subzones allow 7 ft front fences when not in a corner cut‑off area and when the fence is ≥70% open (vertical openings). See § 822.3.050 and check the R‑1 subzone for exact exceptions.

Do large retail or warehouse projects need extra landscape buffers?

Yes. Designated large commercial and industrial/warehousing projects must provide scale‑dependent buffers and walls (examples: 5 ft buffer + 6 ft wall for >25,000 sf commercial; industrial thresholds may require 7–10 ft walls at larger sizes). See § 822.3.090.E–F and the related Tables (Table 2‑6/2‑8).

What are the county rules for trees and parking‑lot shade?

Commercial/industrial landscaping requires drought‑tolerant, evergreen trees, minimum 24‑inch box size, spaced at no greater than 40 ft on center (species‑dependent). For parking areas on developments >50,000 sf, the code requires 35% shade coverage at maturity or photovoltaic shade structures as an alternative. See § 826.3.020.A–B.

Must mechanical equipment and dumpsters be screened?

Yes. Roof or ground‑mounted mechanical equipment, loading docks, refuse areas, and utility services must be screened from public view and from adjacent residential/commercial areas using architecturally compatible methods; refuse/recycling enclosures must be screened with masonry walls, gates, and landscaping and meet pad and access requirements. See § 822.3.090.B and § 822.3.120.C.

Do landscaping plans have to meet state water‑efficiency rules?

Yes. All landscaping design, installation, and maintenance must comply with the California Model Water Efficient Landscape Ordinance (MWELO) as adopted by Fresno County in § 826.3.010.

If I plan an accessory dwelling unit (ADU), do these screening/landscaping standards apply?

Landscaping and screening requirements in the Zoning Ordinance apply in the unincorporated area, but ADU rules can alter development constraints. Verify ADU landscaping specifics with the County and consult California ADU law; explicit ADU landscaping standards were not found in the retrieved materials. Verify with the jurisdiction.

Where do I show the 10‑foot street boundary setback for walls?

If the district boundary is a street any wall constructed along that street in a front or side yard must be set back 10 ft from the property line and that strip must be landscaped and maintained; include this on site plans. See § 822.3.090.

Who approves the architectural treatment of screening (walls, gates, trellises)?

The Director (County planning director or designee) reviews architectural compatibility of screening treatments and may require architectural treatment/landscaping on both sides of walls; show elevations and materials and expect Director approval. See § 822.3.090.
