Overview

This page summarizes what the East Palo Alto Development Code (Title 18) requires for landscaping, trees, screening, fences, and walls. It synthesizes the rules that govern private yards, parking lots, equipment screening, and buffering between zones, and it points you to the exact code sections you must follow when you prepare plans. For permitting steps see the city's East Palo Alto Zoning & Planning overview and the East Palo Alto Zoning pages.

Key takeaways up front:

  • Fences/hedges: 4 ft allowed in front setbacks; 6 ft allowed in side/rear setbacks (with narrow exceptions). § 18.26.020 .
  • Parking lot landscaping and screening minimums (street buffer, % of area, tree spacing) are mandatory for lots with more than 10 spaces. § 18.30.090 / § 18.30.040–E .
  • When nonresidential or industrial zones abut residential, walls/solid screens are required: 6 ft (nonresidential) or 8 ft (industrial). § 18.22.040.D .
  • Trees, tree removal, and water-efficient landscaping are regulated under Chapter 18.28 (tree protection, replacement, and the City’s Water Conservation in Landscaping link). § 18.28.010–040 .

When your design must coordinate with other topics, consult the East Palo Alto Development Standards, the East Palo Alto Parking rules (for lot layout and landscaped buffers), and East Palo Alto Design Review (screening and plant palettes are frequently conditioned). If you are planning an ADU, see the East Palo Alto ADUs page and note that landscaping/trees requirements remain controlled by Title 18; verify parcel-specific constraints.

City rules and where they live (code grounding)

  • Fences, hedges, and walls (purpose, height, measurement): § 18.26.010 – § 18.26.030 .
  • Site planning, screening of mechanical equipment, and buffering between zones (vision triangles; required walls adjacent to residential): § 18.22.020; § 18.22.040 .
  • Landscaping and trees (water-conserving landscaping thresholds, tree planting minimums for subdivisions, tree removal permit rules and replacements): § 18.28.010 – § 18.28.040 .
  • Off-street parking lot landscaping and screening (4‑ft street buffer; 5% minimum landscape area for lots >10 spaces; screening height ~36 in; tree spacing and planting size): § 18.30.090 .
  • Variances/minor variances (fence height adjustments, reductions to landscape standards): § 18.90 (Table 7-3) .
  • Design Review and Site Plan requirements (landscape, screening, and mechanical screening are reviewed): § 18.86 .

District-by-district breakdown

Note: the code groups districts into families. Below are the East Palo Alto district families and the landscaping/screening matters that most often differ between them. For zone listings see the Development Code chapters for each district family. Bold items are the exact local district names and standards.

Residential Zones — R-LD, R-MD, R-HD, R-UHD

Purpose and typical uses

  • Purpose: foster a range of housing types from low-density single-family to urban high-density multifamily. See Chapter 18.10 for intent and allowed uses. § 18.10.010 .

Landscaping & screening highlights

  • All required open/private/common open spaces must be landscaped per Chapter 18.28; tree planting and water-efficiency rules apply. § 18.28.030 .
  • Fences/hedges in front setbacks can be up to 4 ft high; side/rear setbacks up to 6 ft unless exceptions apply. § 18.26.020 .
  • Corner lots must keep the corner vision triangle (25 ft) clear of visual obstructions over 48 in; tree canopies must be pruned to at least 7 ft above curb level in that triangle. § 18.22.020 .
    Where it applies
  • Applies citywide within the R- family; landscaping minimums for open space are captured in each district’s development standards (Table 2-2) and Chapter 18.28. § 18.10; § 18.28 .

Practical note: small-lot urban residential projects are still subject to tree-protection and water-conserving irrigation requirements in § 18.28.

Mixed-Use Zones — MUC, MUL, MUH

Purpose and typical uses

  • Mixed-use zones encourage ground-floor commercial/retail or offices with residential above. See Chapter 18.12 for allowed combinations and design emphasis. § 18.12.010–.030 .

Landscaping & screening highlights

  • Site Plan and Design Review will require landscaping integrated with pedestrian routes and frontage treatments; mechanical equipment screening is required per § 18.22.040. § 18.86; § 18.22.040 .
  • Parking areas serving mixed‑use development must meet parking landscaping and buffer rules in § 18.30. See parking guidance. § 18.30.090 .

Where it applies

  • Central business and corridor areas designated in Chapter 18.12 (and sometimes overlay districts). § 18.12 .

Commercial Zones — C-G, C-N, C-O

Purpose and typical uses

  • Neighborhood to general commercial uses; see Chapter 18.14 for permitted uses and center design guidelines. § 18.14.010–.040 .

Landscaping & screening highlights

  • Commercial sites are expected to provide landscape buffers between parking and streets (minimum 4 ft), street trees (typically 1 tree / 30 ft frontage in parking areas), irrigation, and permanent curbing around planters (6” min). § 18.30.090 .
  • When a commercial parcel abuts a residential parcel, a 6‑ft wall is required (owner of the nonresidential parcel constructs/maintains it) unless the Director approves alternate screening. § 18.22.040.D.1 .

Where it applies

  • Commercial corridors and centers defined in Chapter 18.14. § 18.14 .

Industrial / Employment — REC, IT, WO

Purpose and typical uses

  • Employment centers, industrial transition, and waterfront office districts are aimed at jobs and light industrial uses. See Table and chapter references for allowed uses. § 18.14/Chapter listings .

Landscaping & screening highlights

  • Where industrial lands abut residential zones the Code requires a solid masonry wall at least 8 ft high (industrial owner builds/maintains). § 18.22.040.D.2 .
  • Outdoor storage, loading, and mechanical equipment must be screened (chain link is limited; slats and chain link are generally not allowed for equipment screening). § 18.22.040.A–B .

Checklist — what an applicant must satisfy (preliminary)

  • Show fence/wall heights and how height is measured (comply with § 18.26.030) .
  • Demonstrate corner vision triangle clearance for corner lots (25 ft triangle; no >48 in obstructions) (§ 18.22.020) .
  • If parking is provided, include planting plan meeting the 4‑ft street buffer, ≥5% landscape area if >10 spaces, tree species/spacing, irrigation, and curbing (§ 18.30.090) .
  • Show mechanical equipment and roof‑mounted screening details that make equipment not visible from 6 ft above grade; include materials consistent with building design (§ 18.22.040.A) .
  • For nonresidential sites abutting residential, show 6‑ft (or 8‑ft for industrial) wall or approved planting buffer (§ 18.22.040.D) .
  • Submit landscape areas over thresholds with compliance documentation for the City's Water Conservation landscaping rules (Municipal Code Ch. 17.06) and a permanent irrigation plan (§ 18.28.030; § 18.30.090) .
  • If any tree removal is proposed, include a Tree Removal Permit application meeting the notification and findings standards, plus replacement or in‑lieu fee plan (§ 18.28.040) .
  • Prepare to address screening/landscaping in Design Review or Site Plan review when projects are discretionary — see East Palo Alto Design Review. § 18.86 .

Verify with the jurisdiction for parcel‑specific surveys and if your work triggers other public improvements (street tree requirements are set by the City Engineer) (§ 18.58).

Risks & Ambiguities

Issue Why it matters What to verify
Tree removal may trigger permit Removing any regulated tree can require a permit and replacement or an in‑lieu fee, delaying work Verify whether the subject tree is protected, submit Tree Removal Permit, confirm replacement ratio and valuation method per § 18.28.040
Corner vision triangle vs. desired screening Desire for privacy screening in corner yards conflicts with the 25‑ft triangle and 48‑in height limit Check triangle extents on a site plan and propose alternative buffering outside the triangle; cite § 18.22.020
Parking lot landscape percentage and tree sizes Noncompliance can cause redesign or conditions of approval (5% min; trees 15 gal/6 ft min) Confirm parking count triggers and plan with species/irrigation per § 18.30.090
Screening method approval (wall vs. planting) Director may accept plantings instead of walls only if design/maintenance are guaranteed If substituting plant screens, be ready to post a 3‑year bond and get Director approval (§ 18.30.090.E)
Fence height at uneven grades Code measures fence height from highest adjacent finished grade; lower neighbors may claim taller fence Submit grade survey and show measurement per § 18.26.030 and the uneven grade allowance (max 8 ft in extreme circumstances) § 18.26.030.B
Mechanical equipment screening and height Screening that increases roofline may trigger discretionary height/Design Review issues Confirm screening stays within mechanical equipment limits and height caps in § 18.22.040; coordinate with East Palo Alto Development Standards and Design Review

Plain‑English Summary

East Palo Alto’s Development Code requires water‑wise landscape plans for larger projects, minimum trees on subdivisions, specific parking‑lot buffers and tree sizes, modest front-yard fence heights (4 ft) and taller side/rear fences (6 ft), and mandatory walls or dense screens where nonresidential or industrial uses meet homes; trees and mechanical equipment must also be screened and maintained. Check Chapters 18.22, 18.26, 18.28, and 18.30 when you design or apply. Verify parcel specifics with the City. § 18.22; § 18.26; § 18.28; § 18.30

Frequently asked questions

Do I need a permit to remove a tree in East Palo Alto?

If the tree is a regulated tree as defined by the City, you must follow the Tree Removal Permit procedures in § 18.28.040; the code lists notification, required findings for removal, replacement or in‑lieu fee rules, and appeal rights.

What maximum fence height can I build on a typical single‑family lot?

Fences, hedges, or walls up to 4 ft are allowed in the front setback; 6 ft is allowed in side and rear setbacks (with corner‑lot limitations and exceptions). See § 18.26.020.

Can I put up a 6‑ft fence at a corner lot’s street side?

Corner lots must respect the corner vision triangle (25 ft from the intersection). Within that triangle, no obstructions over 48 in are allowed; outside it you may use the standard side/rear limits. See § 18.22.020 and § 18.26.020.

What are the parking lot landscaping requirements I must show on plans?

A minimum 4‑ft landscaped buffer is required between any parking area and a street; where a lot has more than 10 spaces, landscaped areas including the buffer must be at least 5% of the parking lot area; trees should be water‑efficient evergreens, min 15 gal / 6 ft at planting, and permanent irrigation is required (§ 18.30.090).

If my commercial parcel faces homes, do I have to build a wall?

Yes — where a nonresidential zone abuts a residential zone the code requires a minimum 6‑ft wall (the nonresidential owner constructs and maintains it), though Director‑approved screen planting may be substituted with guarantees (bonding, maintenance). § 18.22.040.D.1.

Do landscape and tree rules apply to small residential improvements like an ADU?

Yes. Landscape and tree requirements in Chapter 18.28 apply to landscape projects meeting the thresholds and to any proposed tree removal; small ADU projects still must respect fences, corner triangles, and tree protections; check East Palo Alto ADUs and § 18.28.

Will Design Review require me to change my plant palette or screening?

Design Review commonly conditions landscaping and screening to ensure compatibility, year‑round screening, and compliance with irrigation/water efficiency rules — see the Site Plan & Design Review chapter § 18.86 and plan to show plant species and maintenance.

Can I use chain‑link fence with slats to screen mechanical equipment?

Chain link (with or without slats) is not allowed for screening ground‑mounted mechanical equipment; the code expects fences, walls, or solid hedges approved by the Director. § 18.22.040.A.3.

What if I need a taller fence than the code allows?

Minor variances can be requested; Table 7‑3 in § 18.90 shows that the Director may approve modest increases (for example, allowable fence height increases up to 7 ft in certain side/rear setbacks under a minor variance). § 18.90 (Table 7‑3).

Where are the exact zone rules that determine how much open space must be landscaped?

Zone development standards (e.g., Table 2‑2 for residential and the mixed‑use/commercial development standards) reference that required open space is to be landscaped in compliance with Chapter 18.28; consult the specific zone chapter (Chapters 18.10, 18.12, 18.14) for parcel‑level dimensional standards.
