Atascadero — Landscaping and Screening

Last reviewed: July 3, 2026

Overview

This page summarizes what the Atascadero municipal zoning ordinance requires for landscaping, screening, fences/walls, street trees, and buffers. It is drawn from the zoning/title provisions that organize those rules under the Landscaping, Screening and Fencing heading and related development-standards and planned-development sections (the local zoning ordinance identifies these rules under several § 9‑4.* provisions). Verify parcel-specific requirements with the City; some items are modified by planned development overlays, design review, or conditions of approval.

What the code requires (top-level synthesis)

• The landscaping, screening and fencing rules are codified under § 9‑4.124 through § 9‑4.129. They state purposes and organize the standards for where landscaping is required, what materials count, plan content and fencing/screening rules.
• Where landscaping is required: all project sites requiring approval except single‑family dwellings must landscape required setbacks, unused areas, parking areas, trash enclosures, and street frontages (including minimum street trees). See § 9‑4.125.
• Street trees: minimum 15‑gallon size; spacing and clearances vary by tree class (large, medium, accent) and the code sets maximum spacing, sidewalk offsets, and minimum clearances to buildings; trees within 10 ft of sidewalks/roads require root barriers and deep‑root watering. See § 9‑4.125(a)(5).
• Allowed landscaping materials (non‑single‑family projects): minimum sizes for trees (15‑gallon) and shrubs (1‑gallon), drought‑tolerant planting encouraged, structural features (walls, fences, fountains) allowed; invasive/noxious species, plants with damaging roots, or plants that impair sight distance are prohibited. See § 9‑4.126.
• Landscape plans and maintenance: required for applicable projects; required plantings must be maintained and replaced if they fail; the city may record a maintenance agreement. See § 9‑4.126(c) and the landscaping plan index § 9‑4.127.
• Screening: mechanical equipment, trash enclosures, outdoor storage, and utility substations must be screened. Nonresidential uses abutting residential zones must have a solid wall/fence along the side/rear lot line unless the Design Review Committee (DRC) finds screening infeasible. See § 9‑4.128(a) and (c).
• Fence/wall height & materials: the code sets height maximums by district (street/front setbacks vs side/rear yards), minimum transparency in street setbacks, and prohibits certain materials (e.g., exposed chain link, barbed/razor wire except in limited circumstances). Height measurement rules account for retaining walls and berms. See § 9‑4.128(c).
• Substitution: a planted landscape screen may substitute for a solid wall/fence only if certified to reach 60% blockage in 18 months and 100% in 36 months (with a requirement to install a wall if the planting fails). See § 9‑4.128(c)(3).
• Parking lot screening & landscape strips: parking lots that abut residential zones require a minimum 5‑ft landscape strip and a 6‑ft solid fence/wall; parking adjacent to streets requires a 10‑ft landscape strip with a decorative 3‑ft solid fence/wall or a landscape equivalent. See § 9‑4.119(g).
• Watercourse/wetland areas: in watercourse‑adjacent areas, fences are allowed if 75% open (split rail, welded mesh), landscape walls < 3 ft allowed; other placement limits apply. See § 9‑4.175.

Note: many Planned Development overlays and project‑specific Master Plans add or modify landscaping, screening and fence aesthetics and maintenance requirements; those appear in individual PD sections (examples: PD‑17, PD‑18, PD‑30, etc.). See the PD entries in Chapter 9‑3 for project‑specific requirements.

District-by-district breakdown (how the landscaping & screening rules vary across Atascadero zones)

(Each subsection below states the controlling code excerpts and practical takeaways. For design guidance or deviations see the city's Design Review process and Atascadero Development Standards.)

RS (Residential Single‑family / Rural)

• Purpose & typical uses: single‑family and rural residential; see general residential zone rules in Title 9. (Specific permitted uses are listed elsewhere in the zoning chapters; see the Atascadero Zoning page.)
• Key landscaping/screening rules that apply:
  • Fence heights: within street setbacks up to 5 ft (top 2 ft must be ≥80% open visibility); side/rear setback fences up to 6 ft. See § 9‑4.128(c)(1)(i).
  • Agriculture‑type, high‑visibility deer fencing may be up to 7 ft in rural RS/RR zones (must be ≥80% open). See § 9‑4.128(c)(1)(i)(b).
• Where it applies: typical single‑family lots and larger rural parcels; single‑family residences are largely exempt from the automatic landscaping requirements for other project types, but fences and screening rules still apply. See § 9‑4.125 and § 9‑4.128.

RSF‑X / RSF‑Y / RSF‑Z (Single‑family residential subcategories)

• Purpose & typical uses: single‑family residential varieties (density and lot size distinctions apply in underlying zoning chapters).
• Key rules:
  • Fencing: in lower‑lot‑area RSF zones (e.g., RSF‑Y less than one acre), front/primary street setback fences max 4 ft; side/rear setbacks max 6 ft. See § 9‑4.128(c)(2).
  • Landscaping: single family lots are largely excepted from the general mandatory landscaping for other projects, but PDs and subdivision standards (e.g., PD17, PD7) require landscaping percentages and consistent fences. See PD entries § 9‑3.662 and § 9‑3.651.
• Practical note: gate height and gate setbacks are regulated for residential gates (gates setback a minimum 20 ft from right‑of‑way; gates up to 12 ft permitted with conditions). See § 9‑4.128(c)(iii).

LSF‑X / LSF‑Y / LSF‑Z (Lower density single family) and RMF‑10 / RMF‑20 (Multifamily)

• Purpose: small‑lot single family and multifamily standards appear in the development standards and PDs.
• Key rules:
  • Fence and fence‑style requirements for multifamily developments include consistency across the project, materials standards, and the ability to use landscaping as internal screening where certified. See § 9‑4.128(c)(2)(d) and § 9‑4.128(c)(3).
  • Multifamily projects must meet landscape/open space minimums (PDs and specific multifamily sections reference open space and landscaping; see § 9‑4.126 and specific PDs).

CS / CPK / IP / I (Commercial & Industrial)

• Purpose & typical uses: commercial, neighborhood/park commercial, industrial/industrial‑park uses.
• Key rules:
  • Parking lot landscape strips, perimeter landscape requirements, and screening for outdoor storage are enforced—industrial zones may allow otherwise prohibited security fencing (barbed/razor) only with Design Review approval. See § 9‑4.119(g) and § 9‑4.128(c)(2)(ii).
  • Sales lots: require a 10‑ft landscaping strip adjacent to street property lines and 6‑ft screening on interior property lines (solid wall/fence or equivalent). Chain link along street frontage is expressly prohibited on sales lots; decorative rail fencing limited to 3 ft behind sidewalk. See the sales lot standards in § 9‑4.125 and § entries for sales lots.

Planned Development Overlays (PD—e.g., PD‑17, PD‑18, PD‑27, PD‑30, PD‑35)

• Purpose: PDs set site‑specific master plan rules and commonly add stronger/unique landscaping, screening and fence design requirements (consistent materials, maintenance responsibilities, tree protection and special landscape areas). See PD entries § 9‑3.662, § 9‑3.663, § 9‑3.675, § 9‑3.680, etc.
• Practical takeaway: where a parcel sits in a PD overlay, the PD’s landscape plan and appearance review requirements usually control and may require higher landscape percentages, uniform fencing design, preservation of protected trees, and mandatory maintenance agreements. See relevant PD section for the parcel.

Quick reference table — decision‑relevant standards

Practical guidance and interpretation (plain‑English, technical implications)

• If your project is anything other than a single‑family home, expect a required landscape plan showing setbacks, parking landscaping, street trees and trash‑enclosure screening per § 9‑4.125 and § 9‑4.127; the city enforces minimum planting sizes (trees 15‑gal; shrubs 1‑gal) and maintenance obligations.
• Fence proposals must be checked against the underlying zone: front/street setback fences are the most constrained (often 4–5 ft with transparency rules), while side/rear yards are typically 6 ft maximum. If you want a taller fence (>6 ft) or a fully solid fence in a street setback, budget for a minor conditional use permit or design review exception—DRC or Planning Commission modification pathways are available. See § 9‑4.128(c)(iii) and the DRC exception authority.
• For projects abutting residential zones, plan to include a six‑foot solid screen or an approved landscape screen (with certification) along the property line (nonresidential uses). If you propose to use plantings instead of a wall, bring a planting performance certification and a contingency plan to install a wall if plantings fail. See § 9‑4.128(a)(4‑5) and § 9‑4.128(c)(3).
• Parking lot screens: if your lot abuts homes, the code requires both a landscape strip and a solid 6‑ft screen to reduce noise/glare—these standards are enforced with plan review. See § 9‑4.119(g).
• Trees shown to be protected in a PD or other approved plan must be preserved or require specific approval for removal under the city's native tree requirements and PD conditions; many PDs explicitly require tree maintenance and replacement provisions. See PD examples § 9‑3.663 and § 9‑3.674.
• Where your site is near creeks or wetlands, additional placement limits apply (fence openness, no crossings beyond top‑of‑bank) and ministerial approvals are identified in § 9‑4.175. If the project impacts jurisdictional wetlands, state/federal agency permits will likely be required.

Checklist (what an applicant must provide / satisfy for typical non‑SFR development)

• Comply with § 9‑4.125: show landscaping in required setbacks, unused areas, parking areas, and street frontage (including street trees).
• Submit a landscape plan meeting the requirements listed in § 9‑4.127 (plan content, species, sizes) — verify with Community Development for the exact plan checklist. Not all plan details were present in the retrieved materials; confirm with staff. Verify with the jurisdiction.
• Plant 15‑gallon minimum trees and 1‑gallon minimum shrubs where required per § 9‑4.126; avoid species prohibited as invasive or with damaging roots.
• Show parking lot landscape strips and screening per § 9‑4.119(g) if parking abuts residential or public streets.
• If substituting plants for a required wall, provide landscape architect certification of growth performance per § 9‑4.128(c)(3) and a contingency plan.
• For fences/walls: dimensioned elevations showing heights measured from downhill grade, and compliance with the fence‑by‑district table in § 9‑4.128(c).
• Ensure mechanical equipment, trash enclosures and outdoor storage are screened per § 9‑4.128(a).
• If in a PD overlay, conform to the PD’s approved Master Plan of Development landscape and fence standards (see the PD’s section in Chapter 9‑3).

Risks & Ambiguities

Plain‑English summary

If you’re developing in Atascadero (anything other than a typical single‑family house), you’ll need a landscape plan that shows street trees (15‑gal minimum), landscaped setback/parking strips, and screening for trash, equipment and parking; fences in front setbacks must be low and often partly transparent, side/rear fences are usually limited to 6 ft, and in many cases planting can substitute for a wall only if it reliably reaches screening goals within a set timeframe (backed by the city’s planting and maintenance rules). See § 9‑4.124–9‑4.128 for the controlling rules.
