Santa Maria — Landscaping and Screening

Q: Do I need a landscape plan for a single‑family yard in Santa Maria?

If your new landscape area is less than 500 sq ft you may be able to use the prescriptive measures from the State's Model Water Efficient Landscape Ordinance; projects with ≥ 500 sq ft of new landscape require the full water‑use calculations and a submitted landscape/irrigation plan in compliance with § 12‑44.03(e) .

Q: What are the fence height limits in front yards in Santa Maria?

Front‑yard fences are generally limited to 3 ft high. A 6 ft wall may be allowed along interior side lot lines and in the front yard where it is set back 10 ft (and meets parcel width limits and corner cutback rules); see § 12‑27.02 and review sight triangles in § 12‑27.03 .

Q: How much planting do I need for a commercial site?

Commercial and manufacturing sites must provide at least 15% of the site as planted open space (minimum); multi‑family sites have a 20% minimum. These are baselines — projects can be required to provide more through permits or PD process — see § 12‑44.04(u) .

Q: What are the parking‑lot landscaping requirements?

Provide 1 tree per 6 parking spaces , at least 200 sq ft of planter area per 20 spaces, and screen parking from streets with 3 ft berms or shrubs; keep trees ≥ 10 ft from driveway approaches to protect sight lines — see § 12‑44.04(l) .

Q: Are existing trees protected?

Yes. Show all existing trees > 6 in. trunk diameter on your landscape plan. Preservation is required unless a Parks Department finding shows hazard or impracticability; if a protected tree is removed, replacement trees must be planted per the ordinance ratios — see § 12‑44.04(n) .

Overview

This page summarizes what the City of Santa Maria's zoning and landscape rules require for landscaping, screening, buffers, fences, walls, and trees. It is drawn from the City's Title 12/Title 17 zoning excerpts and the Landscape Standards (Chapter 12‑44) and the fence/screening and district development standards that control how and where screening and planting are required. For site design, check parking, development standards, and design-review rules as they interact with landscape and screening requirements. Santa Maria Zoning & Planning overview and Santa Maria Zoning are the right starting pages for permits and district maps.

Key rules at a glance

All new development must meet the City's Landscape Standards (Chapter 12‑44) including water‑efficient irrigation and a landscape plan for most projects; see § 12‑44.01 – § 12‑44.05 .
Minimum planted open space: 15% of site area in commercial and manufacturing districts; 20% in multi‑family residential districts (minimums; may be raised by permit) — see § 12‑44.04(u) .
Parking‑lot landscape and screening: 1 tree per 6 parking spaces and 200 sq ft of planter per 20 spaces; 3‑ft berm/shrub screening from streets (with clear‑vision exceptions) — see § 12‑44.04(l) .
Tree protection: show all existing trees > 6 in. diameter on plans; retention is required unless Parks staff find hazard/unworkable; replacement ratios apply if removed — see § 12‑44.04(n) .
When a non‑residential lot abuts a residential zone, a combination of fencing/walls and landscape screening is required, subject to the Zoning Administrator — see § 12‑17.11(a) and similar district screening rules (multiple districts) .
Fence/wall height limits: generally 3 ft in required front yards (exceptions allow 6 ft where set back or in side/rear yards); corner cutback sight triangles apply — see § 12‑27.02 and § 12‑27.03 .

For interactions with vehicle layout and parking lot planting, consult Santa Maria Parking. For instances where design quality/compatibility matters, expect Santa Maria Design Review review. If your site is in an overlay expect Santa Maria Overlay Districts rules to add requirements.

District-by-district breakdown

Below are the districts most relevant to landscaping and screening in Santa Maria, with the ordinance‑backed requirements that typically trigger landscape/screening obligations.

R-1 (Single‑Family Residential)

Purpose & typical uses: single‑family homes and accessory uses. See general residential district rules in Title 12/13.
Landscaping & screening basics: Front‑yard fences are limited to 3 ft maximum within required front yards; 6 ft maximum allowed along interior side lot lines or in front yards if the wall is set back 10 ft from sidewalk/property line and not longer than 1/3 parcel width; trellises/arbors have special allowances — see § 12‑27.02 and § 12‑27.03 .
Where it applies: Citywide single‑family areas; corner lot landscaping requirements (landscaped side yard 10 ft) apply in mixed contexts — see § 12‑17.10(b) .
Permit notes: Most residential landscaping under 500 sq ft can follow prescriptive watering measures; projects ≥ 500 sq ft must meet the State's Model Water Efficient Landscape Ordinance as implemented by § 12‑44.03(e) .

RSL‑1 (Single‑Family Small Lot Residential)

Purpose & typical uses: Small‑lot single‑family product.
Landscaping & screening: Follows the same fence height limits, but the Neotraditional Neighborhood rules alter front yard easement setbacks (trellis/fence placement) — see § 12‑27.02 (Neotraditional-specific text) .
Where it applies: Neotraditional plan areas and small‑lot subdivisions; verify project‑specific plan requirements.

Multi‑Family (RM / R‑multiple)

Purpose & typical uses: duplexes, apartments, condos.
Key landscape standards: Minimum planted open space 20% of gross site area in multi‑family residential districts as a baseline; front/rear/side yard planting requirements to mitigate glare/noise — see § 12‑44.04(u) .
Screening: When abutting lower‑intensity residential uses, landscaped setbacks and fences/walls may be required per § 12‑44.04(t) and district screening rules .

C‑1 / C‑2 / CM (Retail / General Commercial / Commercial Manufacturing)

Purpose & typical uses: Retail, services, offices, light commercial/manufacturing.
Landscaping & screening: Commercial and manufacturing districts must provide at least 15% planted area of the site; parking area planting and screening rules in § 12‑44.04(l) apply (trees per spaces, planter area, 3‑ft street screening) .
Buffering: If a commercial property abuts an R district, a landscaped setback and combination of fence/wall and planting is required and subject to Zoning Administrator approval — see § 12‑17.11(a) .
Where it applies: City commercial corridors and industrial parks; special street‑front landscaping may be imposed on major streets (e.g., Miller St., College Ave.) — see § 12‑44.04(p) .

M‑1 / M‑2 (Light / Heavy Manufacturing)

Purpose & typical uses: industrial and manufacturing uses where screening from offsite residential views is frequently required.
Landscaping & screening: Same planted area minimum (15%), strong emphasis on screening for open storage and hazardous areas (solid walls/fences 6 ft may be required), and requirements for landscaping around walls (tree per linear feet) — see § 12‑44.04(u) and § 12‑17.11(b–c) .
Permits: Planned development overlays on industrial sites may allow modifications so long as findings ensure additional visible landscaping is provided to offset any setback reductions — see § 12‑35.203 .

RMH (Mobile Home Park)

Purpose & typical uses: mobile home parks.
Landscaping & screening: Entire front yard and side yard along streets must be landscaped; trash/utility yards screened together with fencing; exterior park boundary walls of not less than six feet are required — see § 12‑9.13 – § 12‑9.14 .
Where it applies: Properties zoned RMH and mobile home park developments.

PD and PD‑f Overlays (Planned Development / Freeway Tower overlay)

Purpose & typical uses: Customized development standards for specific projects or freeway‑facing towers.
Landscaping & screening: The Planning Commission may impose special landscape/wall/tree standards and may modify setbacks where superior landscape mitigation is provided; PD‑f requires “substantial adjacent landscaping” and trees for freeway towers — see § 12‑35.203 and PD‑f rules (referenced in Chapter text) .
Where it applies: Properties with an adopted Planned Development overlay.

Most decision‑relevant standards (quick reference table)

Topic	Requirement (typical)	Code Reference
Landscape chapter purpose / applicability	Landscape plan, water efficiency for most new public/private projects; projects ≥ 500 sq ft trigger full water‑use calculations	§ 12‑44.01–12‑44.03
Minimum planted area — commercial/manufacturing	15% of site area (minimum)	§ 12‑44.04(u)
Minimum planted area — multi‑family	20% of site area (minimum)	§ 12‑44.04(u)
Parking lot trees	1 tree per 6 parking spaces	§ 12‑44.04(l)(1)
Parking planters	200 sq ft per 20 spaces (min)	§ 12‑44.04(l)(2)
Parking screening from street	3 ft berm/shrub screening; trees min 10 ft from drive approaches	§ 12‑44.04(l)(4)
Existing tree protection	Show trees > 6 in. diameter; limits on grade change and pavement over dripline; replacement ratio table applies	§ 12‑44.04(n)

Synthesis & practical guidance

Start your design at § 12‑44.03–12‑44.05 for the landscape plan, water‑use calculations, and irrigation standards; projects with ≥ 500 sq ft of new landscape must meet the Model Water Efficient Landscape Ordinance technical rules built into the City code (so provide a water‑budget or use the prescriptive path when eligible) .
Use the parking‑planting rules in § 12‑44.04(l) to size your parking planters and street‑edge screening: allocate trees early (1 per 6 stalls) and reserve 200 sq ft per 20 stalls for planters to avoid rework during plan check . Link your parking layout to Santa Maria Parking early.
If your site borders residential zoning, expect a landscape buffer and a combined fence/wall and planting solution; the Zoning Administrator has discretion on how these are met — quote § 12‑17.11(a) when asking for clarification or alternative treatments .
For trees: identify all trees >6 in. diameter on the site plan, follow the protection rules for grade and pavement near retained trees, and apply the replacement schedule if removal is approved — § 12‑44.04(n) contains the tree inventory and replacement guidance .
Fence/wall designs must satisfy the front/side/rear height limits and corner sight triangles in § 12‑27.02 and § 12‑27.03; verify any exception with the Zoning Administrator and reference the corner‑cutback triangles to avoid visibility conflicts .
If your project is inside a PD or specific plan area, expect site‑specific landscape obligations or possibilities to trade setback for superior visible landscaping under the planned development findings § 12‑35.203 .

Note: where the ordinance cross‑references Building Code constraints (e.g., clearances around mechanical equipment or fire sprinklers), those are separate (see California Building Standards Code) and must be coordinated; do not treat those state building standards as replaced by this landscaping code.

Checklist

Prepare a landscape plan consistent with § 12‑44.04 (plant list, hydrozones, irrigation schematic) and include a maintenance schedule .
Show all existing trees >6 in. diameter, call out trees to remain or be removed, and include replacement calculations if removal is proposed (§ 12‑44.04(n)) .
For projects ≥ 500 sq ft of new landscape, include a water‑budget per the Model Water Efficient Landscape Ordinance (§ 12‑44.03(e)) .
Lay out parking lot planters and trees to meet 1 tree / 6 stalls and 200 sq ft / 20 stalls minimums (§ 12‑44.04(l)) .
For any lot abutting an R zone, include a combined fence/wall + planting buffer and note Zoning Administrator approval path (§ 12‑17.11(a)) .
Confirm proposed fence/wall height and setback comply with § 12‑27.02 and sight triangles § 12‑27.03; dimension setbacks on drawings .
If in a Planned Development/Specific Plan area, review PD conditions and be prepared to show “superior landscape” tradeoffs per § 12‑35.203 .
Coordinate screening of mechanical equipment, backflow devices and trash enclosures with the landscape plan (screening is explicitly required) — see § 12‑44.04(q–r) .

Risks & Ambiguities

Issue	Why it matters	What to verify
Tree removal/replacement math	The code prescribes replacement ratios by trunk diameter; under‑replacing will trigger correction or denial	Check the tree replacement table and get Parks/Zoning Administrator confirmation; cite § 12‑44.04(n)
Front‑yard wall exceptions	Walls up to 6 ft are allowed only under specific setback/length rules; misplacing a 6‑ft wall can violate sight triangles	Confirm allowed setback (10 ft in many cases) and the 1/3 parcel width length limit; cite § 12‑27.02 and § 12‑27.03
Planned Development modifications	PD approvals can change setbacks/landscape obligations, but only with specific findings	If seeking setback reduction, document how extra visible landscaping offsets impacts and reference § 12‑35.203
Applicability of water‑budget rules	Some small projects can use the prescriptive path; others must submit the full water budget	Verify square‑foot thresholds: 500 sq ft new landscape triggers full calculations (§ 12‑44.03(e))
Conflicting requirements across chapters	Landscape chapter defers to more restrictive rules (setbacks, specific plans)	Review the applicable district chapter, any Specific Plan, and overlay rules; if conflict, higher restriction controls (§ 12‑44.03(b))

When in doubt about parcel‑specific interpretations, verify with the Community Development Department or the Zoning Administrator. Verify with the jurisdiction.

Plain‑English Summary

Santa Maria requires a water‑efficient, reviewed landscape plan for most new development, sets numeric minimums for planted area (commercial/manufacturing 15%, multi‑family 20%), mandates parking‑lot trees and planters, protects existing trees over 6 inches unless replaced per code, and limits fence/wall heights in front, side and rear yards with sight‑triangle rules; when non‑residential lots touch residential zones, combined fencing and planting buffers are required — see the cited code sections for exact thresholds and to confirm parcel‑specific exceptions.

If my non‑residential lot touches a residential zone, what screening is required?

A combination of fencing/wall and landscape screening is required where a lot abuts a residential zone; the exact treatment is subject to Zoning Administrator approval and the district's screening rules — see § 12‑17.11(a) .

Are existing trees protected?

Yes. Show all existing trees > 6 in. trunk diameter on your landscape plan. Preservation is required unless a Parks Department finding shows hazard or impracticability; if a protected tree is removed, replacement trees must be planted per the ordinance ratios — see § 12‑44.04(n) .

Can I use decorative rock instead of plants to meet landscape area requirements?

Non‑living materials may be used to accent plantings but may not serve as the primary ground cover unless minimum plant counts are maintained (for example, one 5‑gal plant per 25 sq ft of planter area) — see § 12‑44.04(d) .

Does the City require screening for trash enclosures and backflow devices?

Yes — trash enclosures and backflow prevention devices must be identified on the landscape plan and provided with adequate landscape screening; masonry walls should be softened with vines or vertical planting where appropriate — see § 12‑44.04(q–r) .

Will a Planned Development (PD) allow me to reduce a landscape/setback requirement?

A PD can modify or delete certain setback/landscape requirements only if the Planning Commission makes specified findings that the modification results in superior design and additional visible landscaping to offset impacts — see § 12‑35.203 .

Who enforces the landscape and screening rules?

The Community Development Department reviews conformity with Chapter 12‑44 and the Zoning Administrator has discretionary authority on many screening/fence decisions; appeals from administrative decisions go to the Planning Commission — see § 12‑44.03(c–d) and procedure sections .
