Piedmont — Landscaping and Screening
Landscaping and Screening under the Piedmont local zoning and planning code, with the controlling citations.
Last reviewed: July 2, 2026
Overview
This page summarizes what the City of Piedmont's zoning ordinance requires for landscaping and screening (plants, fences, walls, trash enclosures, terracing, and maintenance) in each zoning district. It is drawn from Chapter 17 (Planning and Land Use) and explains when a landscape plan or design-review permit is required, minimum landscape percentages by zone, fence/wall height limits, and special rules for screening trash and corner sight triangles. For related topics see the city’s pages on Piedmont Zoning, design review, parking, development standards, overlay districts, ADUs and the California Building Standards Code.
Key ordinance rules (plain-English, code pointers)
Landscape plans: required with an application for a conditional use permit, design review permit, or variance for a new residence or other building; the city may also require a plan where site disturbance is substantial. See § 17.34.020 for when plans are required and what they must include.
Mandatory street-setback landscaping: a residential owner must landscape required street setback areas (except paved driveways). See § 17.34.040.
Landscape plan review timing and appeal: the landscape plan is decided together with the underlying permit and may be conditioned (including irrigation). See § 17.34.030.
Landscaping completion and maintenance: the city may require financial security, and all required landscaped areas must be planted with living material and maintained; mulch must be organic. See § 17.34.050–060.
Fences, walls, retaining walls, terracing: height limits and design-review triggers are in § 17.32.010 (table of heights and when design review is required). Notably, a retaining wall up to 30 inches is allowed without design review; fences/walls in a street setback require design review at any height. See § 17.32.010 and the trash-enclosure rule § 17.32.020.
Corner sight triangles: no fence, wall, hedge or vegetation over 3 feet within the triangular sight-distance zone measured 30 feet along each curb extension unless approved. See § 17.32.030.
Trash enclosures: must be solid or open fence/wall 4–6 feet tall or dense evergreen planting screening at least 4 feet at maturity; within a street setback the planning counter will review compliance but a design-review permit is not required if standards are met. See § 17.32.020.
Design review thresholds: many fences, walls, retaining walls, and any improvement requiring a variance or building permit are subject to design review; the thresholds and which body reviews (Director vs Planning Commission) are in § 17.66.030–040. See especially the Planning Commission triggers for fences/retaining walls in a street yard setback or retaining walls over 30 inches.
District-by-district breakdown
Below are the zoning districts in Piedmont (the code uses Zone A, Zone B, Zone C, Zone D, Zone E) with the landscaping/screening items applicants most often need to check. For each district I list purpose, typical permitted uses, the most relevant dimensional/landscaping standards and where that district typically applies.
Zone A — Single-family residential (see § 17.20.040)
Purpose & uses: established for detached homes; single‑family residences, ADUs, small family day care, some care homes. See § 17.20.020–030.
Key landscaping/screening standards:
- Minimum 30% landscaping of the lot (subject to ADU exceptions) — § 17.20.040.

- Street yard setback: 20 ft minimum for primary/accessory structures; required street setback areas must be landscaped (see § 17.34.040).
- Fences and retaining walls: refer to § 17.32.010 for height limits and design-review triggers; small retaining walls ≤ 30 in. generally do not need design review, but fences within the street setback do.
Where it applies: most residential lots in the city; Zone A rules also apply to private structures or fences on city easements unless otherwise stated (see § 17.06.050).
Zone B — Public facilities (see § 17.22.040)
Purpose & uses: public buildings, schools, parks, cemeteries, utilities, housing types including multifamily and ADUs in some cases — permitted uses listed at § 17.22.020.
Key landscaping/screening standards:
- City projects are exempt from most development standards but must meet (1) green‑building chapter requirements and (2) the bay‑friendly landscaping rules referenced in the municipal code (see § 17.22.040.A).
- For non-exempt uses, Zone B generally follows Zone A standards (including minimum 30% landscaping where Zone A standards apply) — § 17.22.040.B.
Where it applies: municipal parcels, parks, Piedmont Unified School District sites, utilities. See § 17.22.040 for special-case rules.

Checklist
- Include a landscape plan with applications that require a design review, conditional use permit, or variance (see § 17.34.020).
- Show required street‑setback landscaping on plans (residential street setbacks must be landscaped except paved driveways) — § 17.34.040.
- For fences/walls: confirm height vs § 17.32.010 table and whether design review is triggered (street‑yard fences always trigger review) — § 17.32.010 & § 17.66.030–040.
- Trash enclosure: specify enclosure type and show evergreen screening if used; ensure 4–6 ft heights or planting at maturity ≥ 4 ft — § 17.32.020.
- For multi‑family, commercial, or special‑area projects, confirm the district landscaping % standard (Zones A/C/D/E as applicable) and apply it on the plan — e.g., § 17.20.040; § 17.24.040; § 17.26.050; § 17.28.040.
- Confirm whether your project will be routed for design review or ministerial design review; if applicable, budget for the public‑notice process and potential conditions — § 17.66.
- Include irrigation/specifications if requested by Planning Director (the decision‑maker may require irrigation). § 17.34.030.
Risks & Ambiguities
| Issue | Why it matters | What to verify |
|---|---|---|
| Street‑setback fences/walls | Any fence/wall in a street setback triggers design review at any height; unexpected review can delay building permits. | Verify whether the proposed fence is within the street setback and therefore triggers § 17.32.010 and § 17.66.030. |
| Corner sight triangles | Vegetation or walls above 3 ft in the 30‑ft triangle violate sight requirements and may be ordered removed. | Confirm the triangle on your lot plan and measure existing/proposed planting or wall heights — see § 17.32.030. |
| ADU exemptions vs landscaping % | State ADU laws limit local ability to impose landscaping/open‑space rules on certain ADU projects; local ADU rules also include exceptions. | For ADUs, cross‑check Piedmont ADU rules and state ADU law — see § 17.38 (ADU division) and note exceptions indicated in the zoning tables (e.g., no landscaping requirement for junior ADUs). Verify with § 17.38 and the ADU page. Not found in retrieved materials: full text of § 17.38 in the excerpts, verify with the jurisdiction. |
| What counts as “landscaping” | The code defines landscaping and hardscape; disputes affect % calculations. | See the definitions and measurement rules (definitions of landscaping/hardscape, site feature exceptions) — check the definitions in Article 5 / Measurements. Verify measurement method with Planning Director. |
| Trash enclosure in street setback | The code says a compliant enclosure may avoid design review but will be reviewed at the planning counter — inconsistencies can cause rework. | Follow § 17.32.020 standards exactly and confirm counter review outcomes before building permit. |
| Maintenance bonds or deposits | City may withhold final approval until landscaping complete or require deposit; budget/time impacts. | Expect escrow/letter of credit requirements per § 17.34.050 and plan schedule accordingly. |
Plain‑English summary
Piedmont requires landscape plans for most discretionary approvals, sets district‑specific minimum landscaping percentages (for example 30% in Zone A, 15% in Zone C, 40% in Zone E, and 10% for the Grand Avenue subarea in Zone D), and strictly controls fences, walls and trash screening—fences within street setbacks always trigger design review and corner sight triangles cannot be planted or built above 3 ft. Always check whether your project triggers design review and include irrigation/maintenance details and the required percentage of planting on your plans (§ 17.34; § 17.32; district tables).

Frequently asked questions
Do I always need a landscape plan for a house remodel in Piedmont?
If the project requires a design review permit, conditional use permit, or variance (for a new residence or other building), a landscape plan must be included — see § 17.34.020. The Planning Director or Commission may also require a landscape plan for building permits that substantially disturb the site.
What is the minimum landscaping percentage for a single‑family lot in Piedmont?
For Zone A (single‑family) the ordinance requires minimum 30% landscaping of the lot (exceptions may apply for ADUs under division 17.38) — § 17.20.040.
If I build a fence along the street, do I need design review?
Yes. Any fence or wall within a street setback requires design review at any height; other fences outside street setbacks generally do not require design review if ≤ 6 ft, but higher fences or other circumstances trigger review — see § 17.32.010 and the design review rules § 17.66.030.
How high can vegetation or hedges be at a corner lot?
Vegetation, hedges, fences, or walls in the corner sight‑distance triangle (measured 30 ft along front and side lot lines from the extended intersection) may not exceed 3 ft in height, unless approved by the Planning Commission — § 17.32.030.
What are the rules for trash enclosure screening?
Trash enclosures must be either a solid fence/wall 4–6 ft tall, an open fence up to 6 ft combined with dense evergreen planting ≥ 4 ft at maturity, or dense evergreen planting alone ≥ 4 ft at maturity. An enclosure within a street setback is reviewed at the planning counter for compliance and is expected to follow the Piedmont Design Standards and Guidelines — § 17.32.020.
Will the city require me to maintain my landscaping after installation?
Yes. All required landscaped areas must be planted with living materials, irrigated and maintained in a healthy condition; the city may require a maintenance contract or financial security and may withhold final approval until landscaping is complete — § 17.34.050–060.
Does Piedmont treat commercial corridor landscaping differently?
Yes. Zone D has subarea distinctions: the Civic Center subarea may have no minimum landscaping, whereas the Grand Avenue subarea requires minimum 10% landscaping — see § 17.26.050. Plan accordingly for Grand Avenue projects.
Do design standards or the Piedmont Design Guidelines affect plant choice and screening appearance?
Yes — landscape plans and screening must conform to the Piedmont Design Standards and Guidelines, and the decision‑maker may attach conditions (including irrigation). The guidelines are an applied criterion for design review approvals under § 17.66 and the landscape provisions in § 17.34.
Can ADUs be limited by local landscaping/open‑space rules?
State ADU law limits how local open‑space and landscaping requirements can be used to deny or unreasonably restrict ADUs; Piedmont’s ADU division contains local rules and exemptions (see division 17.38). The code excerpts show ADU exceptions to some lot coverage/landscaping rules; verify the full ADU text and state law when planning an ADU. Not all ADU subsections appeared in the retrieved snippets — verify with the planning counter.
Who decides whether my fence or landscaping needs discretionary design review?
The Director administers most design-review applications; the Planning Commission reviews projects that meet specified thresholds (e.g., fences in a street yard setback, retaining walls over 30 in., project valuation thresholds) — see § 17.66.040 for the decision body and applicability.
