Morgan Hill — Landscaping and Screening
Landscaping and Screening under the Morgan Hill local zoning and planning code, with the controlling citations.
Last reviewed: July 2, 2026
Overview
This page summarizes what the Morgan Hill Zoning Code requires for landscaping and screening (including fences, walls, trees, and parking-lot planting). It pulls only from the Morgan Hill zoning ordinance (Title 18) as supplied and points to the exact controlling code sections so you can verify requirements and prepare application materials. Key chapters are Chapter 18.64 (Landscaping), Chapter 18.52 (Fences and Walls), Chapter 18.72 (Parking and Loading / Parking Lot Landscaping), and the residential transition standards in § 18.92.130 (residential buffering / tree screens) — see the Source References at the end for the files cited (e.g., § 18.64.040, § 18.52.080, § 18.72.070, § 18.92.130).
Note: this page stays strictly within zoning / planning rules; it does not cover Title 24 or building-code details — see the California Building Standards Code page if you need those standards.
What the Morgan Hill code requires (synthesis)
- Landscape plans are required for projects that need a design permit and for additions that materially enlarge buildings; the code lists required plan contents (plant species, sizes, existing trees, irrigation plans, grading) (§ 18.64.020–§ 18.64.040).
- Parking lots have minimum interior-planting percentages and shade-tree requirements (one shade tree per five spaces; interior landscaping 10–20% depending on lot size) and perimeter screening rules (screening adjacent to streets and residential zones, with minimum heights) (§ 18.72.070).
- Where commercial or industrial uses abut residential zones, the code requires robust screening — typically a decorative or landscaped masonry wall with a minimum height of seven feet (and other architectural/landscape compatibility requirements) (§ 18.52.080.D).
- Fence/wall heights and permitted materials vary by district; view-obstructing fences are tightly limited in front setbacks, some materials are outright prohibited in residential districts, and the community development director may grant limited minor exceptions for topography or adjacent open space (§ 18.52.050–§ 18.52.060).
- Residential transition standards require a minimum landscaped planting strip of 10 ft along residential property lines for mixed-use/commercial sites, and a tree screen planted at a maximum interval of 15 ft (the planning commission may allow greater spacing for appropriate species) (§ 18.92.130.C.3).
- Landscaping must meet water-efficiency and irrigation specifications, including drip irrigation for trees, irrigation efficiency minimums, and timing of installation prior to final inspections (§ 18.64.030–§ 18.64.070).
- Screening of mechanical equipment, refuse/recycling areas, and outdoor storage must be provided and be architecturally/landscape-compatible with the site (§ 18.40.x and § 18.52.080).
First natural mentions of some related topics are linked for navigation: see the code overview at Morgan Hill zoning & planning overview, consult the zoning map at Morgan Hill Zoning, use Morgan Hill Development Standards for dimensional tables, check Morgan Hill Parking for parking-lot context, coordinate design-level questions with Morgan Hill Design Review, and check overlay impacts at Morgan Hill Overlay Districts. Consider Morgan Hill ADUs rules when adding secondary units and always cross-check building/craft rules with the California Building Standards Code.
District-by-District breakdown (landscaping & screening implications)
Below are the Morgan Hill district names and the landscaping/screening items that most often affect approvals. Each district entry lists purpose or typical uses (from the code), where the landscaping/screening rules are applied, and the key standards you must watch for.
Residential Detached Low Density — RDL (includes RDL-20,000, RDL-12,000)
- Purpose / typical uses: single-family detached homes and large-lot neighborhoods; standards and development tables are in Chapter 18.16 (Table 18.16-3) .
- Landscaping/screening highlights: single-family projects are subject to the general landscaping chapter when a design permit is required; small-lot subdivisions and courtyard projects require five-foot planter strips and tree plantings to shade sidewalks and buffer adjacent uses (§ 18.40.060 and related small-lot criteria).
- Key dimension notes: typical front setbacks and lot coverage are in the RDL tables; fencing in front setbacks is limited (see Fences & Walls below) — consult § 18.52.050 for height exceptions.
Residential Attached (RAL / RAM / RAH) — RAL, RAM, RAH
- Purpose / typical uses: duplexes, townhomes, small-lot multifamily (Chapter 18.18/18.40). Multifamily projects require more formal screening for mechanical and trash areas; common open space must be landscaped and visible to units. Landscape plan and screening of utilities/refuse are required on permits.
Commercial zoning — CN, CG, CO, CH, CS
- Purpose / typical uses: neighborhood retail, general commercial, office, highway/service commercial (Chapter 18.24).
- Landscaping / screening implications: where commercial parcels abut residential zoning, Residential Transition Standards apply (increased setbacks, planting strips, tree screens — § 18.92.130) and screening for outdoor storage, loading docks, and refuse is required (§ 18.52.080, § 18.92.125).
- Parking-lot rules: parking lots must meet the parking-lot landscaping rules (interior planting %, shade trees, perimeter screening — § 18.72.070).
Industrial — IL, IG, IC, IO, CI
- Purpose / typical uses: light to general industrial and campus industrial uses (Chapter 18.26). Landscaping and screening for industrial uses often require heavier materials (masonry walls, berms) where sites interface with residential zones — minimum seven-foot decorative masonry wall for commercial/industrial uses adjacent to residential (§ 18.52.080.D). Prohibited fence materials in industrial front setbacks are spelled out in § 18.52.060.
Form-Based / Mixed-Use districts — MU-D, MU-N, MU-F and FB-* (FB-N, FB-C, FB-UG)
- Purpose / typical uses: walkable mixed-use corridors and downtown nodes (Chapter 18.29 / form-based code). These districts have supplemental landscaping rules (see 18.29.080) and additional requirements where MU zones abut residential (they must comply with § 18.92.130).
- Design-review tie-in: form-based projects are often design-permit-triggering and will require the landscape plan content at § 18.64.040. See the Morgan Hill Design Review page for procedural context.
Open Space / Public Facilities — OS, PF, SRL
- Purpose: preserve natural and park/open-space lands (Chapter 18.28). Fencing exceptions (e.g., open wrought-iron up to six feet in OS and Residential Estate districts) are recognized; landscape requirements prioritize preservation and may be relaxed where appropriate (see § 18.52.050 exceptions).
Quick reference table — most decision-relevant standards
| What to watch for | Standard / requirement | Code Reference |

| Residential transition tree buffer | Landscaped planting area min 10 ft and a tree screen with trees at max 15 ft spacing (planning commission may adjust) | § 18.92.130.C.3 |
| Maintenance and performance guarantees | Landscaping must be maintained per approved plans; the city may require a maintenance agreement or bond (2-year guarantee; bond may equal 100% of planting/irrigation value) | § 18.64.070.B |
Checklist (applicant must satisfy)
- Prepare a full landscape plan with items listed in § 18.64.040 (site boundaries, existing trees with DBH, plant list/species/sizes, irrigation plan, grading)
- Show parking-lot landscaping calculations and tree counts per § 18.72.070 (interior % + 1 tree per 5 spaces)
- Provide perimeter and residential-adjacent screening detail (materials, heights: 3 ft along streets; 6 ft where parking is within 10 ft of residential; 7 ft masonry where commercial/industrial abuts residential) and cite § 18.72.070 and § 18.52.080.D
- Demonstrate irrigation efficiency and water conservation compliance (referenced Chapter 18.148 and § 18.64.030) and show drip irrigation for trees, controllers, backflow devices, etc.
- If replacing or relocating trees, check protected-tree rules (Municipal Code Chapter 12.32) and pruning limits in § 18.64.070.A.4; obtain required tree permits if needed.
- If screening includes fences/walls, ensure materials/heights comply with § 18.52 (and mark any requested minor exceptions or design permit justification)
- Be prepared to sign a landscape maintenance agreement or post a bond per § 18.64.070.B if required.
- Coordinate screening of mechanical equipment, transformers, and refuse enclosures with the site plan and show architectural compatibility (§ 18.40.x, § 18.92.125, § 18.52.080).
Risks & Ambiguities
| Issue | Why it matters | What to verify |
|---|---|---|
| Protected / significant trees not addressed on plan | Could trigger tree-removal permits or conditions; tree pruning/topping is restricted | Confirm whether any trees are protected under Chapter 12.32 and obtain tree removal permits if required (verify with Development Services). Not found in retrieved materials: exact tree-protection lists — verify with jurisdiction. |
| Measurement of fence/wall height vs adjacent grade | Height limits and exception calculations depend on how height is measured across sloped lots | Confirm base grade used for height measurement and whether minor exception (Section 18.52.050) is necessary for grade differences (§ 18.52.050). |
| What constitutes an "opaque screen" | Determines whether planting + open fence is acceptable or a masonry wall is required | For parking within 10 ft of residential the code explicitly requires a six-foot masonry wall — confirm proposed treatment matches § 18.72.070 and § 18.52.080.D. |
| Fire / WUI vegetation rules vs. landscape screening | Wildfire fuel-reduction requirements can affect species choice, berms, and mulches | Verify compliance with local fire authority requirements / Wildland-Urban Interface guidance; some WUI code excerpts are in the materials but parcel-specific rules may apply — Verify with the jurisdiction and fire authority. |
| HOA or private covenants | Private CC&Rs can be stricter than the code and prevent certain fence types | The zoning code does not override private covenants; verify any HOA rules. Not found in retrieved materials: HOA specifics — verify with title/HOA. |
Plain-English Summary
If you need a landscape plan or screening in Morgan Hill, expect to submit a detailed plant-and-irrigation plan when your project needs a design permit; parking lots must include interior landscaping and shade trees, commercial/industrial neighbors to homes generally require a tall masonry/landscaped screen, and fences in front yards are tightly limited in height and materials — all spelled out in Chapters 18.64, 18.72, and 18.52 of the Morgan Hill Zoning Code (see the specific § citations below).

Frequently asked questions
Do I need a landscape plan for my Morgan Hill project?
Yes — if your project requires a design permit or is an addition increasing floor area or market value by 25% or more, a landscape plan with the contents listed in § 18.64.040 is required (plant lists, existing trees, irrigation, grading).
What are Morgan Hill parking-lot landscaping requirements?
Parking lots must provide interior landscaping based on size (16–30 spaces = 10%, 31–60 = 15%, over 60 = 20%), and one shade tree per five spaces (24" box, 30' canopy) — see § 18.72.070 (Table 18.72-6 and Shade Trees).
How tall can my fence be in the front yard?
Front-setback fence height limits vary by district; view-obstructing fences in front setbacks are restricted (chain link/solid board typically limited to 3 ft in the front setback in many residential contexts), and minor exceptions can be granted for topography or adjacency to parks — see § 18.52.050–§ 18.52.060.
Does the city require masonry walls between commercial/industrial and homes?
Yes — commercial or industrial uses adjacent to residential zones are required to be screened by a decorative or landscaped masonry wall with a minimum height of seven feet (or equivalent screening as approved) per § 18.52.080.D.
What does Morgan Hill require where a commercial or mixed-use site borders homes?
When a non-residential or higher-intensity site abuts residential land, the project must follow the Residential Transition Standards: increased setbacks, a 10-foot planting strip along residential property lines, and a tree screen planted at up to 15-foot intervals (planning commission may adjust spacing for appropriate species) — § 18.92.130.
Are there irrigation or water-efficiency rules for landscape plans?
Yes — landscaping must comply with the local water-conservation requirements and specific irrigation standards: minimum irrigation efficiency, drip required for trees, controllers with rain sensors, separate meters for large landscapes, and installation before final building inspections — see § 18.64.030 and § 18.64.040.
Can I use chain link or barbed-wire fencing?
The code prohibits barbed wire, razor wire, chain link, sheet metal and electric fences in residential zoning districts; commercial and industrial districts have more limited allowances but restrict certain materials in front setbacks and where adjacent to residential uses — see § 18.52.060.
Will the city require a maintenance bond or agreement for landscaping?
The city may require a landscape maintenance agreement and/or bond to guarantee maintenance (landscaping must be maintained per approved plans; bonds or agreements often guarantee maintenance for two years; bond amount up to 100% of landscaping/irrigation value) — § 18.64.070.B.
Where do I show screening for trash and mechanical equipment?
Screening for mechanical equipment and refuse/recycling enclosures must be shown on plans; refuse enclosures have specific design and location requirements (solid masonry materials, gated access, landscaped planters) and must not be visible from rights-of-way — see § 18.92.125 and the screening provisions in Chapter 18.40.
If my site is in a form‑based district, are the landscaping rules different?
Form-based districts (FBC / MU zones) include supplemental landscaping standards (Chapter 18.29.080) and may supersede or add to other landscaping rules; where the FBC is silent, the general zoning code applies. Projects in FBC areas commonly require design review and landscape plans too.
