Gardena — Landscaping and Screening
Landscaping and Screening under the Gardena local zoning and planning code, with the controlling citations.
Last reviewed: July 2, 2026
Overview
This page explains what the City of Gardena's zoning ordinance requires for landscaping, screening, fences/walls, parking lot planting, and equipment/refuse screening. It is grounded in Gardena's Title 18 zoning rules: the citywide landscaping regulations, fence standards, parking-landscape requirements, and the zone-specific development standards that add or refine those rules. For permit timing or building-code construction details, verify with the city (see checklist). See the Gardena zoning overview for broader context.
Key citywide rules you must know (summary)
- A complete landscape plan is required for most new or expanded multifamily, commercial, and industrial projects; plans must show plant species, sizes and spacing and comply with irrigation and water-efficiency rules in § 18.42.075.
- Front setbacks for commercial/industrial properties must be landscaped (minimum 10 ft or 20 ft when adjacent to residential) under § 18.42.085.
- Parking-lot planting minimums (trees, planter widths, curb protection, xeriscaping) are in § 18.40.090 (including one 24‑inch box tree per 10 parking spaces and minimum 3 ft-wide planting beds).
- Fences/walls: front setback fences/hedges are limited to 3.5 ft (interior lots) / 3 ft (corner lots); side/rear fences may be up to 8 ft; materials and streetscape setbacks are regulated in § 18.42.070.
- Mechanical equipment, rooftop and ground-mounted, must be screened; ground units may be screened with matching materials or landscaping per § 18.42.140.
- Refuse enclosures must be screened from public view and, where adjacent to landscaped areas, planted with vines or similar per § 18.42.130.
(When a specific plan or overlay applies it can modify these standards — see the Overlay Districts page.)
District-by-district (zoning) breakdown — landscaping & screening specifics
Note: the following subsections summarize standards that either appear in the zone's property development standards or rely on the citywide landscaping/fence rules. Always check the parcel's exact zone and any specific plan or overlay that may apply; specific plans can supersede ordinary zone rules. Verify with the jurisdiction for parcel‑specific requirements.
R-1 (Single‑Family Residential) — § 18.12.050
- Purpose / typical uses: single‑family homes.
- Landscaping/screening highlights: Front yard setback: 20 ft; no more than 50% of the front yard (including driveways) may be paved — the remainder must be permanently landscaped with softscape and a permanent irrigation system (city approval required) per § 18.12.050.G.1–5.
- Fences/walls: front setback fences limited to 3.5 ft (interior) / 3 ft (corner) and front-yard fence materials limited to wood, wrought iron, tubular steel, stone, brick, stucco, or decorative block; side/rear fences up to 8 ft where allowed § 18.42.070.
Practical note: if you are replacing front yard hardscape (driveway/patio) you must show the softscape percentage and irrigation on plans; see Development Standards for measurement rules. Development Standards
R-2 / R-3 / R-4 (Multi‑family Residential, incl. cluster developments) — Chapters 18.14–18.18
- Purpose / uses: duplexes, small multifamily to higher-density residential (varies by chapter).
- Landscaping/screening highlights: cluster and multi‑family projects must provide usable open space and landscaping; not less than 10% of outdoor open space must be planted and irrigated per § 18.42.065 and must meet the planting and irrigation standards of § 18.42.075.
- Fences/walls and visibility cutbacks follow § 18.42.070; cluster developments can have exceptions allowing up to 8 ft fences in front setbacks if accompanied by 5 ft of landscaping between sidewalk and fence and wrought‑iron/tubular steel design (see § 18.42.070.A.2.d).
Practical note: plans for multifamily must include a landscaping maintenance strategy and irrigation specification; site plan review will inspect these items. Design Review
C‑P / C‑2 / C‑3 / C‑4 (Commercial zones; heavy commercial = C-4) — § 18.26 / § 18.34
- Purpose / uses: professional offices, retail, restaurants and, in C‑4, highway‑oriented and heavier commercial uses.
- Landscaping/screening highlights: commercial and industrial properties have mandatory landscaped front setbacks—generally 10 ft front landscape setback (or 20 ft where adjacent to an R zone) and landscaped side/rear setbacks when abutting residential, often with an 8‑ft masonry screen wall along residential property lines (then stepping down to 3.5 ft within front yard) per § 18.42.085.
- Parking lots must meet parking‑landscaping standards (planters, tree counts, curb protection, and xeriscape preference) in § 18.40.090.
Practical note: if a commercial parking area abuts a residential zone, expect an 8 ft masonry wall + planting; on streetside frontages a 3 ft masonry wall or hedge is required. Always show these on your site plan.
M‑1 / M‑2 (Light / Heavy Industrial) — § 18.36.060 (M‑1 example)
- Purpose / uses: warehouses, manufacturing, distribution.
- Landscaping/screening highlights: 10‑ft landscape setbacks along street frontages, automatic irrigation, and truck/loading areas must be screened from public view by an 8‑ft high wall, accessory structure, or landscaping (see § 18.36.060.C–D).
- Fencing/walls: barbed wire is prohibited where visible from the public; any high security fencing visible to the public may require conditional permits.
Practical note: industrial uses frequently require screening for loading and mechanical areas; show plant sizes, berms, and wall materials on the plan.
P (Public / Institutional) — § 18.22.050
- Purpose / uses: public buildings, parks, water works, etc.
- Landscaping/screening highlights: where P abuts R zones, a 20‑ft landscaped front yard is required; side/rear abutting residential typically require an 8‑ft masonry wall (reduced within front yards) per § 18.22.050.
Specific plans / overlays
- A specific plan or overlay may create different landscaping and screening standards for a targeted area; see the Specific Plan chapter and Overlay Districts. When a specific plan exists, its provisions govern. Overlay Districts

Checklist — what an applicant must include for landscaping & screening
- Site plan that shows property zoning and any specific plan/overlay affecting the lot (verify with the city) .
- Full landscaping plan for projects covered by § 18.42.075 showing botanical/common names, sizes, quantities, spacing, and a planting key § 18.42.075.C.
- Irrigation plan with an automatic system and controllers using ET or soil moisture sensors § 18.42.075.F.1.a.
- Show water‑use classification for plants (WUCOLS) and confirm ≥ 75% water‑efficient plantings § 18.42.075.E.1.
- Parking landscape layout: tree counts (one 24‑inch box per 10 spaces), planter widths ≥ 3 ft, curbs, and xeriscape areas § 18.40.090. Parking
- Fence/wall elevations and materials, showing compliance with front‑yard limits (3.5 ft interior / 3 ft corner), street frontage landscape setbacks, and any cluster exceptions § 18.42.070.
- Equipment and rooftop screening details (materials, colors, ventilation open area), or planting buffer for ground units § 18.42.140.
- Refuse enclosure location, elevations, and screening (opaque gates or enclosed within building) § 18.42.130.
- Maintenance plan (who maintains irrigation and plant replacement) — the code requires permanent maintenance and thriving condition of plantings § 18.42.075.F.
- If requesting reduced landscaping (administrative adjustment), include findings to support the adjustment § 18.50.030.
Risks & Ambiguities
| Issue | Why it matters | What to verify |
|---|---|---|
| Specific‑plan or overlay overrides | A Specific Plan can change or supersede zone landscaping rules, so standard zone tables may not apply. | Verify whether the parcel is inside a Specific Plan or Overlay before finalizing plans. |
| Measurement of fence height on sloped lots | Height is measured from the higher side of the grade; noncompliance can trigger corrections or variances. | Confirm grade baseline and show fence profile on plan; reference § 18.42.070.C. |
| Water‑use classification (WUCOLS) | The code ties acceptable plants to WUCOLS lists; wrong species could violate the 75% water‑efficient requirement. | Provide WUCOLS citations for plant selections and note the source listed in § 18.42.075 (verify current WUCOLS link). |
| Visibility / sight‑triangle rules | Landscaping or hedges can become illegal hazards if they block driver sightlines at corners. | Ensure landscape plans respect intersection visibility cutbacks in § 18.42.110 and fence visibility rules in § 18.42.070.B. |
| Conflicting standards between parking chapter and zone | Parking chapter has planting detail; zone may add a different front‑setback landscape dimension. | Show both parking and zone landscaping calculations on plan; include cross‑references to Ch. 18.40 and applicable zone section (e.g., § 18.12.050 for R‑1). |
| Equipment clearances / fire code conflicts | Screening placed too close to equipment may violate fire or utility clearance rules. | Verify required clearances with utilities and the Fire Department; the zoning rule allows landscaping for screening but utility clearances still apply. Verify with the jurisdiction. |
Plain‑English summary
Gardena requires most commercial, industrial and multifamily projects — and many residential front yards — to include permanent, irrigated landscaping, tree counts in parking lots, and proper screening for trash and mechanical equipment; front yard fences are limited in height and materials, and industrial/commercial edges next to residences usually require tall masonry walls or landscaped buffers. Follow the citywide rules in § 18.42.075, the fence rules in § 18.42.070, parking landscaping in § 18.40.090, and the zone’s property standards for the parcel.

Frequently asked questions
What landscaping information must I put on site plans for a commercial project in Gardena?
Include a full landscape plan showing botanical and common names, size and quantity of plants, spacing/design, irrigation type (automatic with ET or soil moisture controller), compliant water‑use percentages and any parking lot trees/planters; these requirements are in § 18.42.075 and parking planting rules in § 18.40.090.
How tall can a residential fence be along my back property line in Gardena?
Residential side and rear fences may be up to 8 ft in height; front‑yard fences are limited to 3.5 ft (interior lots) and 3 ft (corner lots) unless a cluster‑development exception applies; see § 18.42.070.
Do I need to plant trees in a new parking lot? How many?
Yes. Parking landscaping standards require tree planting — typically one 24‑inch box tree for every 10 parking spaces (or two 15‑gallon trees if fewer than 10 spaces) and planter widths of at least 3 ft; see § 18.40.090.
If my commercial site borders homes, what screening does Gardena require?
When a commercial or industrial parking lot or rear yard abuts a residential zone, Gardena requires an 8‑ft decorative masonry wall along that property line (stepping down to 3.5 ft within the adjacent front setback) or equivalent landscaping per § 18.42.070 and § 18.42.085.
Can I use drought‑tolerant plants, and are there limits on turf?
Yes — Gardena requires that at least 75% of plantings be water efficient (WUCOLS low/very low); no more than 5% of plantings or turf can be high‑water‑use. The code explicitly references WUCOLS in § 18.42.075.E.
Will mechanical equipment (HVAC, transformers) need screening, and how?
Yes. Ground‑mounted equipment must be screened with materials matching the building or with landscaping; rooftop equipment must be screened with matching materials, painted to match, and may use vertical slats so that no more than 20% of screening is open — see § 18.42.140.
Can I replace part of required planted area with hardscape?
Some nonplanted areas (seating, patios, shade structures) may substitute for up to 50% of planted area; however, poured concrete/asphalt is generally prohibited except for accessible paths and sports courts, and front‑setback hardscape cannot exceed 50% of the setback without the required minimum landscape buffer § 18.42.075.G.
If my lot slopes sharply, how is fence height measured?
Fence height is measured from the higher side of the finished grade when a fence, wall or landscape treatment of a specified height is required; see § 18.42.070.C.
Can I ask the city to reduce landscaping requirements for a tight parcel?
An administrative adjustment of up to 20% for landscape standards is possible if the adjustment meets the findings in § 18.50.030; prepare a demonstration showing practical difficulties and neighborhood consistency.
Who enforces the watering and maintenance requirements for required landscaping?
The zoning code requires landscaping to be permanently maintained in thriving condition and irrigation systems kept operational per § 18.42.075.F; enforcement is through the Community Development Department and can be conditioned on site plan approvals.
