Tustin — Landscaping and Screening

Last reviewed: July 2, 2026

Overview

This page summarizes what the City of Tustin's zoning ordinance requires for landscaping, screening, buffers, fences and walls. It pulls the controlling requirements from Title 17 (Zoning) provisions that govern district development standards, parking-area landscaping, and general provisions for fences and zone-boundary walls. For applications that trigger design review, off‑street parking, or ADU work, consult those topic pages as noted below. Verify parcel‑specific interpretations with the Community Development Department.

Key city-wide rules (what you must know first)

• Fences, solid hedges and walls: Maximum height on rear/side interior lot lines and rear of front‑yard setback lines is six feet eight inches (6'8"); nothing ≥ 3 ft tall is permitted within required front‑yard setback unless the code allows otherwise. The ordinance text for these rules is in the general provisions for development standards § 9271(i) .

  • Zone‑boundary walls are required in specific adjacencies (e.g., where C, M, or Pr zones abut residential zones): a solid masonry wall 6'8" high is required on the zone boundary, with limited front‑yard exceptions; see § 9271(i)(2)(a–d) .
  • A minor adjustment can permit up to a 20% increase over the 6'8" height for enclosures in the rear half of a lot (see minor adjustment rule) — refer to § 9299(b)(1) for the procedure referenced in the fences clause .

• Parking‑area landscaping & screening: Off‑street parking requires permanent landscaping: at least 5% of interior parking area, perimeter landscaping (min 5 ft wide; 10 ft where abutting a major arterial), tree counts (one 24"‑box per six parking spaces; one tree per 20 lineal feet in perimeter strips), and screening that hides cars to 30–42 inches high; irrigation required. These requirements are in the parking/landscaping development rules § 9266(e)(1–7) . A decorative masonry wall of 6'8" is required where a non‑residential parking/drive area abuts residential property; within a required front yard that wall must not exceed 3 ft subject to visual‑clearance rules (§ 9266(e)(7)) .

• Yard and setback landscaping obligations: In residential districts (example: R‑1) the code requires that all setback areas and all areas not used for walkways, parking, drive aisles or private recreation be fully landscaped and irrigated — see § 9223 (Single‑Family Residential district standards) . Maximum front‑setback coverage references are in § 9267 (see the development‑standards cross reference) .

• Waivers/administrative adjustments: The Community Development Director (Zoning Administrator) can approve minor adjustments (including limited increases in fence/wall height up to 20%) under the minor‑adjustment rules; larger changes require a variance or Conditional Use Permit per § 9299 and § 9291 respectively .

District-by-district notes (where landscaping & screening rules matter)

Below are the principal zoning districts in Tustin where landscaping/screening requirements commonly apply. Each district name is shown with the ordinance section that defines its permitted uses and standards.

• R‑1 — Single‑Family Residential (§ 9223)
  Purpose/typical uses: Single‑family dwellings and accessory uses. Key standards include front yard setbacks (commonly 50 ft in certain areas), lot coverage limits, and the explicit requirement that all setback areas and non‑walkway/parking areas be fully landscaped and irrigated; trees or screening to meet adjoining requirements are applied per development standards § 9223 .

• R‑2 — Duplex Residential (§ 9225)
  Purpose/typical uses: Two‑unit residential uses; landscaping expectations mirror other residential districts and are enforced through Table 1 and the same general landscaping rules in § 9220/§ 9225 .

• R‑3 — Multiple‑Family Residential (§ 9226)
  Purpose/typical uses: Apartments and multi‑family; higher lot coverage and stricter buffering may apply where multi‑family abuts single‑family. Zone‑boundary walls and screening obligations apply where specified in the general fences/walls rules, § 9271(i)(2) .

• R‑4 — Suburban Residential (§ 9228)
  Purpose/typical uses: Suburban‑scale residential; explicitly requires that all lot setbacks be landscaped and irrigated as part of site development § 9228 .

• Pr — Professional District (§ 9231)
  Purpose/typical uses: Offices, professional services. When adjacent to residential, additional perimeter setbacks/landscape buffers are required (see Table 1 / development standards) and the zone‑boundary wall rules in § 9271(i)(2)(a) apply where Pr abuts residential zones .

• C3 — Heavy Commercial (§ 9234) and CG — Commercial General (§ 9235)
  Purpose/typical uses: Retail, commercial, and heavier commercial uses. These districts frequently trigger the parking‑landscaping rules § 9266(e) (perimeter strips, screening heights, tree counts) and require consideration of lot‑coverage and buffering when abutting residential § 9234–9235 .

• SP‑1 — Tustin Legacy Specific Plan (§ 9246)
  Purpose/typical uses: Areas governed by the Tustin Legacy Specific Plan; specific landscape and screening standards are contained in the Specific Plan document and apply in lieu of or in addition to standard district rules § 9246 .

Notes:

• Table 1 of the code (development standards) aggregates setback, lot coverage and other dimensional standards that interact with landscaping obligations; see Table 1 / § 9220 for the baseline numeric standards used in the district boxes above .
• For Planned Development (PD) parcels, approved development plans typically require a detailed landscape plan; the PD approval and final development plan will control onsite landscaping obligations (see PD references in the PD district language and the plot‑plan requirements) .

Most decision‑relevant standards (quick reference table)

Practical guidance & interpretation (plain English synthesis)

• If you propose new parking or redevelop an existing lot, expect to meet the parking‑landscape rules in § 9266(e): plan for 5% interior landscaping, perimeter planting widths, tree counts, screening to 30–42 in, and an automatic irrigation system. Sketch these on the site plan early — they cannot be deferred into "landscape to be determined later" without approval .
• If your project borders different zones (e.g., commercial abuts residential), the code mandates a solid masonry zone‑boundary wall 6'8", unless the Director approves a modification; show the wall on the site plan and note any existing adjacent walls that may satisfy the requirement (the Director may waive or modify where an existing wall can be supplemented with landscaping) § 9271(i)(2) .
• For homes: front yards are protected — fences over 3 ft in a required front setback are generally prohibited. Side/rear fences in the rear half of the lot can be taller, and with a minor adjustment may be up to 20% taller than 6'8" for specific enclosures § 9271(i) and § 9299 .
• Large or site‑specific exceptions (e.g., higher walls for sound attenuation, shared party‑walls, or deviations for design) will require the applicable discretionary pathway: minor adjustment, variance, or Conditional Use Permit — see § 9299(b) for minor adjustments and § 9291 for CUPs .
• If the property lies inside an overlay or specific plan (e.g., SP‑1 Tustin Legacy), the Specific Plan's landscape standards may control; always check the Specific Plan text in addition to Title 17 § 9246 .

Checklist (what an applicant must provide for typical site/parking/adjacency review)

• Site plan showing property lines, zoning designation (confirm via Tustin Zoning) and adjacent zones.
• Landscape plan showing all setbacks, perimeter planting strips (width noted), interior parking landscaping (≥5%), tree species/box sizes and locations (24" box where required). Cite § 9266(e)(1–6) on plan notes .
• Elevations and details for any required zone‑boundary masonry walls (6'8") or proposed alternate screening; reference § 9271(i)(2) .
• Irrigation design or notes confirming a permanent automatic irrigation system for landscaped areas (§ 9266(e)(6)) .
• If proposing fence/wall taller than the code limit or in the front yard, include a minor‑adjustment, variance, or CUP justification (as applicable) and reference § 9299 / § 9291 .
• If the parcel is in a Specific Plan or Overlay, show compliance with that document (e.g., SP‑1 / § 9246) .
• For ADUs, confirm landscaping expectations consistent with the underlying zone and the ADU rules; see the ADU page and § 9223/§ 9228 where relevant .

Risks & Ambiguities

Plain‑English summary

Tustin’s zoning code requires landscaped and irrigated setback areas for most residential zones, sets specific parking‑lot landscaping and tree counts, limits front‑yard fence height to about 3 feet while allowing taller rear/side fences up to 6'8", and mandates masonry zone‑boundary walls (6'8") where commercial/industrial/professional zones meet residential properties. Check the applicable district rules and plan to show planting widths, tree sizes, irrigation, and any required masonry walls on your site plan; modifications require the administrative or discretionary processes identified in the code § 9223, § 9266, § 9271, § 9299 .
