Antioch — Landscaping and Screening

Last reviewed: July 1, 2026

Overview

Antioch’s Title 9, Chapter 5 Zoning Ordinance concentrates landscaping, screening, and fence/wall expectations in a few places: Article 10 (Landscaping and Irrigation), Article 11 (Site Obstructions at Intersections), Article 12 (Tree Preservation and Regulation), Article 13 (Screening of Mechanical Equipment/Outdoor Storage), and Article 16 (Fences, Walls, Hedges and Screen Plantings). These rules interact with use- and district-specific provisions and with Antioch Development Standards approved through Antioch Design Review. Where a project adds or reorganizes parking, also see Antioch Parking.

Article 10 sets citywide submittal, installation, and maintenance requirements for landscaping on commercial, industrial, and most multi-family developments; Articles 11–13 and 16 set visibility limits, tree restrictions, mechanical/outdoor-storage screening, and fence/wall parameters. Together, they form the baseline regardless of underlying zoning, with overlays or special districts layering on top where applicable.

Citywide landscaping and screening standards

• Applicability and exemptions. Article 10 applies to all commercial, industrial, and residential projects that require a planned development, use permit, and/or design review approvals; it also applies to existing buildings over approximately 2,500 sf undergoing significant exterior alterations. Individually owned single-family homes not in a PD and commercial projects not requiring landscape areas are exempt. Before a certificate of occupancy, the City verifies installation and may require a one-year performance bond for plant establishment. Ongoing “maintenance” is mandatory.
• Plan submittals. A preliminary landscape plan is required with applications for final development plan, use permit, and/or design review. Final landscape and irrigation plans (with plant list and automatic irrigation details) must be submitted for building permit and include a maintenance plan; plans may be required to be stamped by a licensed landscape architect. Stormwater control plans must be consistent across all site plans.
• Design standards. Plant materials must emphasize drought tolerance, shade, fire resistance, and coherence with the site; minimum nursery sizes are typically 15-gallon for trees and 5-gallon for specimen shrubs. Crushed rock as large-area cover is discouraged; non-turf areas need 2 inches of mulch; shrub/groundcover areas must reach 75% coverage at maturity.
• Water efficiency. Antioch adopts the state’s Model Water Efficient Landscape Ordinance (MWELO) by reference; compliance is required for applicable landscape areas.
• Visibility at intersections and driveways. Within the “clear vision zone,” no structure, fence, hedge, or vegetation over 3 ft high is permitted; tree canopies must start at least 8 ft above edge of pavement. Larger triangles apply at uncontrolled intersections; smaller at signalized; similar triangles apply at driveways.
• Fences, walls, hedges, screen plantings. Front-yard fences are limited to 36 inches; most other fences max 6 ft. Commercial/industrial fences can reach 8 ft with an administrative use permit; residential masonry sound walls along arterials or schools can be 8 ft with a sound study; interior side/rear residential fences may reach 8 ft if the top 2 ft is open lattice/iron/tubular steel. Barbed/razor wire is prohibited; retaining walls by streets must be outside the right-of-way and use decorative masonry; chain-link along public realm must be vinyl-clad. Walls between residential and nonresidential uses must be masonry.
• Parking lot edge screening. In and around parking areas, fences/hedges/screen plantings must be at least 30 inches tall to screen vehicles.
• Screening of equipment and storage. Exterior mechanical equipment must be screened from public rights-of-way; series of meters on multi-family or multi-tenant buildings must be concealed behind removable screen walls or cabinets. Outdoor storage must be screened per Article 13 and any applicable use standards.
• Trash enclosures. Enclosures must be roofed; not located in required street-side setbacks; landscaped around the perimeter if visible from public view; and may be required to drain to sanitary sewer with measures to contain runoff and prevent stormwater inflow.
• Tree preservation/planting rules. Certain root-invasive species (e.g., cottonwoods, poplars, aspens, and most willows) are restricted or require approval; trees must be planted at least 5 ft from sidewalks, with branches trimmed to clear sidewalks by 7 ft and streets by 14 ft. Vegetation that threatens public facilities is a nuisance subject to abatement.

District-by-district landscape/screening highlights

Note: Antioch’s landscaping and screening rules apply across districts unless a district or use adds stricter standards. Where purpose or permitted uses are not directly tied to landscaping/screening in the retrieved materials, they are noted as “Not found.”

Residential districts — RE, RR, RTR, R-4, R-6

• Purpose, typical permitted uses, baseline dimensional standards: Not found in retrieved materials.
• Key landscaping/screening:
  • Front-yard fence max 36 inches; side/rear fences generally 6 ft.
  • Exceptions: 8 ft residential sound walls along arterials/schools with a sound study; 8 ft interior/rear fences allowed if top 2 ft is open lattice/iron/tubular steel.
  • Visibility triangle: no vegetation over 3 ft within clear vision areas; tree canopy min 8 ft above pavement edge.
  • Trees: minimum 5 ft setback from sidewalk; 7 ft/14 ft clearance over sidewalk/street.
• Where it applies: Citywide on residentially zoned lots.

Commercial districts (citywide category used by code)

• Purpose, typical permitted uses, baseline dimensional standards: Not found in retrieved materials.
• Key landscaping/screening:
  • Fences up to 8 ft with administrative use permit; barbed/razor wire prohibited; chain-link along public realm must be vinyl-clad.
  • Parking edges screened to at least 30 inches with hedges/fences/plantings.
  • Mechanical equipment screened from public rights-of-way.
  • Trash enclosures roofed, planted at perimeter if visible; not in required streetside setbacks.
• Where it applies: Commercially zoned parcels subject to Article 10; also see Antioch Design Review triggers.

Industrial districts (citywide category used by code)

• Purpose, typical permitted uses, baseline dimensional standards: Not found in retrieved materials.
• Key landscaping/screening:
  • Fences up to 8 ft with administrative use permit; walls between industrial and adjacent residential must be masonry.
  • Mechanical equipment and outdoor storage screened per Article 13.
• Where it applies: Industrially zoned parcels subject to Article 10 and screening provisions.

RTC district (Downtown/Rivertown Traditional Commercial)

• Purpose, typical permitted uses: Not found in retrieved materials.
• Key landscaping/screening:
  • Street-front landscaping depth ties to street type for new construction: along an arterial, provide a minimum 30 ft setback with 30 ft of landscaping; on a collector, 25 ft with 25 ft landscaping; on a local street, 20 ft with 20 ft landscaping. Multi-family has reduced landscaped setbacks by street type (e.g., arterial 15 ft).
• Where it applies: RTC-zoned properties in the Rivertown area. Verify exact boundaries with Antioch Zoning.

HPD — Hillside Planned Development

• Purpose, typical permitted uses, baseline dimensional standards: Not found in retrieved materials.
• Key landscaping/screening:
  • Design must preserve natural features and significant trees; fencing cannot visually intrude on hillside character or extend above significant ridgelines when viewed from off-site.
• Where it applies: Parcels zoned HPD. Verify with Antioch Overlay Districts if layered standards also apply.

Use-specific: Automobile service stations (any zoning where allowed)

• Screening and walls:
  • If abutting residential, provide a 6 ft solid masonry wall along shared property lines (reduced to 3 ft adjacent to the neighbor’s front yard). Restroom entrances must be screened by 6 ft decorative screens set 12–18 inches above grade.
• Landscaping:
  • Street-front planters must run the full length (except driveways) and be bermed high enough to screen pump islands from motorists; corner planters min 150 sq ft; provide concrete curbing at least 6 inches high to separate planting areas from pavement.
  • Utilities on site should be underground or, if above ground, enclosed and screened by landscaping as appropriate.

Decision-focused standards (selected)

How design review fits

Many projects that trigger landscape plans will also trigger Antioch Design Review. Minor design review may be approved administratively for landscaping and site features; the Planning Commission can adopt objective design standards addressing landscape treatment citywide. Projects in a Commercial Infill Housing Overlay that meet objective standards may have streamlined design review.

Checklist

• Determine if Article 10 applies (commercial, industrial, or residential project with planned development, use permit, and/or design review; major exterior alterations over ~2,500 sf).
• Prepare a preliminary landscape plan with entitlement submittal; confirm if a licensed landscape architect is required.
• Prepare final landscape and irrigation plans (with plant schedule, automatic irrigation details) and a maintenance plan for building permit.
• Design planting to meet size, coverage, mulch, and drought-tolerant standards; coordinate with stormwater plans.
• Comply with MWELO for water efficiency.
• Site fences/walls to meet height limits and materials rules; ensure masonry walls between residential and nonresidential.
• Maintain clear vision triangles at intersections and driveways.
• Provide screening for parking perimeters, mechanical equipment, outdoor storage, and trash enclosures.
• If Downtown RTC or HPD, incorporate the special frontage landscaping or hillside visual protections.
• Verify tree species/location restrictions and clearance over sidewalks/streets.

Plain-English Summary

If you’re building or significantly remodeling a commercial, industrial, or multi-family site in Antioch, you’ll need a drought-smart landscape plan that meets minimum plant sizes, mulch, and coverage targets, plus permanent irrigation and ongoing maintenance. Keep front-yard fences to 3 feet, most other fences to 6 feet unless you qualify for limited 8-foot exceptions; keep sightlines open at corners; screen parking edges, mechanical units, outdoor storage, and trash areas; follow tree species/location rules; and satisfy any special district extras (like wider landscaped frontages downtown). Most of this runs through Antioch Design Review and coordinates with Antioch Parking and water-efficiency rules.
