Half Moon Bay — Landscaping and Screening

Q: Do I always need a landscape plan for a remodel or addition in Half Moon Bay?

Yes — the zoning code requires a landscape plan for all new construction and extensive remodels; multi‑family and commercial projects have explicit plan requirements and must follow the city's water‑efficient landscaping program ( § 18.07.030 , § 18.06.040 ) .

Q: If my commercial property borders homes, do I need a wall?

Generally yes — a solid masonry or concrete wall at least 6 ft high is required where a nonresidential site borders an existing ground‑floor residential use unless the commercial site provides a 10 ft landscaped buffer; alternatives may be approved by the planning commission or director ( § 18.07.040 ) .

Overview

This page summarizes what the Half Moon Bay zoning code requires for landscaping and screening (Title 18 zoning rules only). It covers when a landscaping plan is required, parking-lot and screening standards, fence/wall heights, tree preservation and replacement, and special rules in scenic corridors, open-space and commercial districts. All requirements below are grounded in the city code; code citations and file references follow each rule so you can verify the authoritative text.

Note: this page stays within zoning/land‑use rules. For building construction or fire/fuel‑modification requirements consult the California Building Standards Code and the local fire authority — those are outside Title 18 and not summarized here.

What the code requires (top‑level rules)

A landscape plan is required for virtually all new construction and extensive remodels; plans must conform to the city's water‑efficient landscaping program and the zoning design criteria (see § 18.07.030) .
Parking lot landscaping: perimeter and interior landscaped areas are required, with a minimum two‑foot planting strip separated by a curb and a minimum of one tree per six parking spaces distributed through the lot (§ 18.37.050) .
Screening: storage/service areas, parking lots, RV parks, rooftop mechanicals, trash enclosures, and utility equipment must be screened by landscaping, berms, or walls per § 18.37.055 .
Scenic corridors / visual resources: where development is visible from scenic corridors, vegetation and low berms (not solid fencing) are preferred for screening; planting must block parking/structures from view within five years of project completion (§ 18.37.030 and § 18.12.025) .
Tree preservation & replacement: existing tree stands should be preserved when possible; removal of significant trees may require permits and replacement planting (see § 18.37.035, § 18.37.045) .
Fence and wall heights (residential rules): rear/side property lines—maximum 8 ft; where adjoining residential property a minimum 6 ft fence may be required along the property line; solid fences within 15 ft of a street property line are limited to 3 ft (the director can approve up to 4 ft if openings ≥50%) (§ 18.07.030) .
Nonresidential adjacent to residential: a solid masonry or concrete wall at least 6 ft high is required along property lines shared by a nonresidential site and existing ground‑floor residential use unless there is a 10 ft landscape buffer on the commercial site; exceptions may be approved by the planning commission or director (§ 18.07.040) .

District-by-district breakdown

Note: district names below are those used in Half Moon Bay zoning text. Where a district has its own specific landscaping/screening rules, the controlling § is cited.

R-1 (Single‑Family Residential)

Purpose & typical uses: R-1 is for single‑family homes; residential development standards in § 18.07.030 apply (setbacks, lot coverage, landscaping, fences, open space) .
Key landscaping/screening standards: landscape plan required for new construction or extensive remodels; tree planting and preservation preferences are in § 18.37.050 and sight‑distance rules apply (trees trimmed to provide a 9‑ft clearance; shrubs ≤ 3 ft in corner sight triangle) .
Fences/walls: rear/side max 8 ft; minimum 6 ft fence may be required along side/rear adjoining residential; street‑front solid fence limits apply (see § 18.07.030) .
Where it applies: across residential neighborhoods citywide; single‑family homes must follow R‑1 development standards § 18.07.030 .

R-2 / R-3 (Two‑ and Multi‑Family Residential)

Purpose & typical uses: R-2 for duplex/2‑unit; R-3 for 3+ units. Projects must meet development standards for the corresponding residential district and submit landscape plans for multi‑family projects (§ 18.07.030, § 18.06.040) .
Key standards: landscape plan required for all new multi‑family residences; parking lot/tree spacing, sight‑distance, and planting specifications apply (see § 18.37.050, § 18.06.040) .
Where it applies: multi‑unit residential parcels across city.

C‑VS and C‑G (Commercial: Visitor‑Serving and General Commercial)

Purpose & typical uses: C‑VS for visitor‑serving commercial uses; C‑G for general commercial. When residential is proposed as part of a commercial zone, residential landscaping/parking rules still apply (§ 18.08.030) .
Key standards: a landscaping plan is required for new construction or extensive remodels in C‑VS/C‑G and must follow the city's water‑efficient landscaping program; outdoor storage/display areas must be screened, and mechanical equipment screened from public rights‑of‑way (§ 18.08.030, § 18.07.030) .
Where it applies: commercial corridors and the downtown visitor areas.

OS / Conservation / Coastal Resource Areas

Purpose & typical uses: OS (Open Space) and mapped coastal resource areas prioritize habitat protection, scenic qualities, and low‑impact recreation.
Key standards: setbacks from coastal resources, additional coastal conservation standards, strict limits on clearing and grading, and specific landscaping/screening requirements for scenic corridors (planting preferred, screening within 5 years) — see § 18.12.025, § 18.12.030, and the coastal resource chapter § 18.38 .
Where it applies: mapped open spaces, shoreline recreation adjacencies, and areas identified in the Local Coastal Program.

Planned Unit / Special Areas (example: Dykstra Ranch planned‑unit)

Purpose & typical uses: projects like Dykstra Ranch have their own design rules embedded in the Title (see § 18.16.035), including privacy fencing restrictions and drought‑tolerant landscaping requirements for the plan area .
Key standards: perimeter fences on side/rear property lines may be prohibited; privacy fencing limited to patios/courtyards and to 6 ft max height in that PUD (§ 18.16.035) .

Scenic Corridors / Visual Resources Overlay

Purpose & typical uses: to preserve public ocean and coastal views and scenic corridors along highways and access routes.
Key standards: structures and landscaping must preserve views; screening should be vegetative/earth‑berm rather than solid fencing; parking/structures visible from scenic corridors must be screened/landscaped to be reasonably blocked from view within five years (§ 18.37.030, § 18.37.035) .
Where it applies: mapped visual resources/overlay areas (verify with the city's overlay map) — see the Overlay Districts page for maps and processes.

Practical guidance / plain‑English synthesis

If you are proposing any new building, an addition that is extensive, a new parking lot, or a change that increases outdoor storage, plan on submitting a landscape plan that follows the city's water‑efficient landscaping program as part of your application — the code makes this a standard requirement (§ 18.07.030, § 18.37.050) .
For parking reconfigurations or new parking areas, allocate interior planting islands and provide at least one tree per six stalls and planting strips (min 2 ft width) separated by curb; plan for trees that won't conflict with utilities or obstruct sight lines (§ 18.37.050, § 18.37.055, § 18.37.050) .
If your project is visible from Highway 1, beach access, or other scenic corridors, expect more emphasis on vegetative screening and low berms rather than solid block fences; the code explicitly discourages solid fencing in scenic corridors to preserve visual quality (§ 18.37.030) .
When commercial development abuts residential uses, be prepared to provide a 6‑ft masonry/concrete wall or a 10‑ft landscaped buffer; planners can allow alternatives when justified — so include a narrative if you’re proposing a different approach (§ 18.07.040) .
Preserve notable trees where feasible; if removal is proposed, confirm whether the removal triggers a municipal tree‑removal permit or replacement conditions (§ 18.37.035, § 18.37.045) .

Checklist (what an applicant must satisfy for landscaping/screening)

Submit a landscape plan with new construction or extensive remodels that conforms with the city's water‑efficient landscaping program (§ 18.07.030) .
Show parking lot landscaping: perimeter and interior planting, min 2 ft planting strips, curbing, and 1 tree per 6 parking spaces (§ 18.37.050) .
Locate and specify screening for trash enclosures, transformers, mechanicals, and outdoor storage (landscaping, berms or walls) per § 18.37.055 .
For projects visible from scenic corridors, include vegetative screening/low berms and a five‑year planting growth/maintenance plan to achieve screening (§ 18.37.030, § 18.12.025) .
Identify existing notable trees and show preservation or replacement measures; if removing significant trees, include permit justification and replacement planting locations (§ 18.37.035, § 18.37.045) .
Show fence/wall heights and construction, especially where nonresidential abuts residential (6‑ft masonry wall or 10‑ft landscape buffer) and street‑front fence height compliance (§ 18.07.040, § 18.07.030) .
Demonstrate sight‑distance compliance at corners (trees 9‑ft clearance, shrubs ≤ 3 ft in the triangular sight area) (§ 18.06.040) .

Verify with the jurisdiction for parcel‑specific constraints and applicable overlays.

Risks & Ambiguities

Issue	Why it matters	What to verify
Which code section controls when overlays and coastal rules overlap	Coastal/overlay rules can be more restrictive than base zone and may change plant/species or setback requirements	Confirm if the parcel lies in a visual resources overlay or coastal resource map; compare § 18.12.025 and § 18.38 requirements and ask planning staff to confirm which standard controls
“Significant tree” removal scope and permit triggers	Removing significant trees can require permits and replacement plantings; failure to follow permit rules can cause stop‑work or mitigation conditions	Verify whether affected trees are “significant” or part of a protected stand (see § 18.37.035, § 18.37.045); consult Community Development Director for required permits
Fence/wall height vs. sight‑distance safety	A tall privacy wall may breach sight triangle or street front height limits, creating a safety or code conflict	Confirm fence heights in relationship to corner sight triangles and street property lines per § 18.07.030 and sight‑distance rules in § 18.06.040
Requirement for masonry wall vs. landscape buffer (commercial next to residential)	The code allows a 10‑ft landscape buffer alternative but makes it discretionary	Verify whether planning commission or director approval is required for alternatives to the 6‑ft masonry wall in § 18.07.040
Planting species and utilities	Wrong species near utilities or with invasive root systems can cause damage and require removal	Trees shall not be planted under utility lines and should use root control in parking strip areas — check planting notes in § 18.37.050

Plain‑English Summary

Half Moon Bay requires a water‑efficient landscape plan for most new construction and major remodels, landscaping in and around parking lots (including a tree every ~6 spaces), and screening of storage and mechanical equipment using vegetation, berms or walls. Fences and walls have clear height limits (rear/side up to 8 ft, streetfront lower), and where commercial meets residential a 6‑ft masonry wall or a 10‑ft landscape buffer is normally required; significant trees should be preserved or replaced if removed. See the cited municipal code sections for specifics and verify overlay or coastal requirements for your parcel.

Frequently asked questions

Do I always need a landscape plan for a remodel or addition in Half Moon Bay?

Yes — the zoning code requires a landscape plan for all new construction and extensive remodels; multi‑family and commercial projects have explicit plan requirements and must follow the city's water‑efficient landscaping program (§ 18.07.030, § 18.06.040) .

How much planting is required in a new parking lot?

Parking lots must include perimeter and interior landscaping with planting strips (minimum 2 ft width, separated by a 6‑inch curb) and a minimum of one tree per six parking spaces distributed through the lot as part of the landscape plan (§ 18.37.050) .

What kind of screening is acceptable for trash enclosures and mechanical equipment?

Screening can be landscaping, earth berms, or walls; rooftop mechanical equipment should be integrated into roof design or screened so it is not visible from adjacent properties or rights‑of‑way per § 18.37.055 .

Are solid fences allowed along scenic corridors?

The code discourages solid fencing in scenic corridors: screening should favor natural vegetation and low berms rather than solid fences to preserve views; the goal is to block parking/structures from view within five years (§ 18.37.030, § 18.12.025) .

If my commercial property borders homes, do I need a wall?

Generally yes — a solid masonry or concrete wall at least 6 ft high is required where a nonresidential site borders an existing ground‑floor residential use unless the commercial site provides a 10 ft landscaped buffer; alternatives may be approved by the planning commission or director (§ 18.07.040) .

What about existing trees — can I remove them?

Significant trees and stands are intended to be preserved; removal often requires a permit and replacement may be conditioned on a one‑for‑one basis. The code requires preservation where possible and replacement planting when removal cannot be avoided (§ 18.37.035, § 18.37.045) .

Are there limits on fence heights in residential neighborhoods?

Yes — in residential districts rear/side fences are generally limited to 8 ft; a solid fence within 15 ft of a street property line is limited to 3 ft, with the community development director able to approve 4 ft where the materials provide ≥50% openings (§ 18.07.030) .

What if my lot is inside a coastal or visual resources overlay?

Overlay rules can be more restrictive: coastal resource and visual/scape standards (setbacks, plant preservation, preferred screening) apply and the more restrictive standard controls. Verify overlay maps and applicable standards in § 18.12.025 and the coastal resource chapters (§ 18.38) .

Will design review look at my landscaping?

Yes — landscaping and screening are part of site and design review considerations for new development and remodels; projects in downtown or historic areas get additional design evaluation (§ 18.37.040, § 18.07.030) .

Does the zoning code say what trees I can plant near utilities or parking?

Yes — the code advises against planting trees directly under or above utility lines and requires root control in tree wells/parking strips for trees with surface root systems; trees should be sited at least 15 ft from major structures unless exceptions apply (§ 18.37.050) .
