Azusa — Landscaping and Screening

Q: What fence height can I build on a typical R‑1 (residential) lot in Azusa?

The code sets common maximums: 42 inches in required front setbacks and 6 feet in side and rear setbacks; fences outside required setbacks may be taller up to the maximum building height. Height is measured from the lowest adjacent grade; special exceptions and minor-use permit modifications exist. These are in § 88.30.020 .

Q: What are the parking-lot tree requirements in Azusa?

Interior parking landscaping must total at least 10% of the parking lot area and include trees at a minimum ratio of one tree per five parking spaces ; required shade trees must be from the city’s approved canopy list and planted at minimum specified sizes. § 88.34.050.D.4 .

Overview

This page summarizes what the City of Azusa's Development Code requires for landscaping, screening, buffers, fences, walls, and trees. It pulls the concrete rules from the Development Code (Title 88 / commonly known as the city's zoning code): how tall fences and walls can be, required planting widths and tree spacing, parking-lot landscape minima, landscape plan submittal rules, and when masonry walls or evergreen screens are required for compatibility between nonresidential and residential uses. See the code text referenced below for full legal wording; the bullets and recommendations here are a plain-English synthesis tied back to the specific code sections. Key controlling rules are in § 88.30.020, § 88.34.050, § 88.34.060, and related sections cited below in Sources.

Note: this page stays limited to zoning/development-code landscaping and screening rules. For building-safety (Title 24) or other permit processes see the California Building Standards Code and the city's permit pages.

What the code requires (quick highlights)

Fences, walls, and hedges have measured height limits by location; typical maximums are 42 in in front setbacks and 6 ft in side/rear setbacks except where exceptions apply; separate rules apply for the West End District (DW). § 88.30.020 explains measurement and limits.
Where a commercial or industrial use abuts a neighborhood zone identified in Article 2, a 6 ft decorative masonry wall plus plant materials is required at the parcel boundary (up to 8 ft where allowed by height-limit exceptions), and a planting strip is required adjacent to the wall (minimum 5 ft; 8 ft where the wall adjoins parking). § 88.30.020.G.1 and § 88.34.050.D.3.d.
Parking lots must provide interior landscaping equaling at least 10% of the gross parking area, with one tree per five parking spaces minimum (and required perimeter planting strips, 1 tree per 25 linear feet). § 88.34.050.D.4 and § 88.34.050.D.3.
Landscape plans (preliminary and final) are required for new development or major remodels; final plans must be prepared by a qualified professional and approved before grading or building permits are issued. § 88.34.020.

(Throughout this page, when I say “review authority,” the code means the director, zoning administrator, or planning commission depending on the permit.)

District-by-district breakdown (how rules apply in Azusa’s actual zones)

Below are the districts/zones that the Development Code actually names in the provisions that affect landscaping and screening. The focus is on purpose, typical uses (brief), and the key landscape/screening standards that apply in each area (with the code section).

West End District (DW)

Purpose & where applied: a specialized district called the West End District; part of Article 2/Regulating Plan. See zoning map for exact boundaries.
Typical permitted uses: a mix depending on subareas; the zone appears in special rules for industrial/auto uses and the West End.
Key landscaping/screening standards:
- Fences/walls: special height table applies — in the West End District many locations allow 8 ft (outside front setback) and wrecking-yard sites have 8–16 ft ranges as noted in § 88.30.020 Table 3-1. Measurement rules apply as in the rest of the city.
- Barbed/razor wire: prohibited citywide except the director may allow it in the DW zone where it is not visible from streets. § 88.30.020.F.1.

Downtown North II — Target Overlay (DNT overlay)

Purpose & where applied: an overlay applied to a specific retail/ downtown parcel to permit transformation and TOD-style redevelopment; overlays supplement the base zone. See the overlay chapter for limits. 88.27.60 (DNT).
Typical permitted uses: retail/mixed-use redevelopment under TOD standards.
Key landscaping/screening standards:
- Under the DNT overlay the base zone standards apply generally, but the overlay explicitly references § 88.30.020 (Fences, Walls, Hedges and Screening) and specifies that some rear setbacks/height relationships may be adjusted per Metro Gold Line requirements; refer to the overlay for exact fence/setback exceptions. § 88.27.60 and § 88.30.020.

Corridor zones (examples: CAZ, CSG, CSA, CAH, CFB)

Purpose & where applied: corridor zones (for major streets such as Azusa Ave, San Gabriel Ave, Arrow Hwy, Foothill Blvd) establish permitted uses and development standards that interact with landscaping and screening standards (Article 2 tables name allowed uses).
Typical permitted uses: retail, service, mixed-use, with various permit levels depending on the corridor. § tables in Article 2.
Key landscaping/screening standards:
- Parking areas that front on streets must include perimeter planting strips equal to the required setback or 10 ft, and shall screen parked cars to a minimum height of 36 in, but must respect sight-line height limits. Trees at 1 per 25 linear feet are required in perimeter areas. § 88.34.050.D.3.a and § 88.34.050.D.3.a.(3–5).

Special Purpose Zones (INS, OS, REC)

Purpose & where applied: institutional, open space, recreation areas; special site planning standards in Table 2-5 supplement Article 3 standards. § 88.28.010 – 88.28.040.
Typical uses: schools, parks, institutional facilities.
Key landscaping/screening standards:
- Site design must still comply with Article 3 landscape standards (minimum landscape widths, plant selection for drought tolerance, and hydrozones). § 88.34.060 and § 88.34.050 apply.

Neighborhood zones / Article 2 neighborhoods (residential areas)

Purpose & where applied: residential neighborhood zoning (various “neighborhood” zones identified in Article 2) — the code repeatedly references “neighborhood zone identified by Article 2” when requiring buffers between commercial/industrial uses and homes.
Typical uses: single-family, multi-family residential.
Key landscaping/screening standards:
- When a nonresidential parking area adjoins residential uses, a minimum 10 ft landscaped buffer is required between the parking and the common property line; plus a solid decorative masonry wall or fence and trees 1 per 25 linear feet. § 88.34.050.D.3.d.
- Between dwellings and adjacent lots evergreen landscape screening is required in some two-unit/lot-split rules: e.g., one 15‑gal plant per five linear feet or 24" box per ten feet; specimens at least 6 ft tall at installation, or a 6 ft solid fence alternative. (Urban lot split / two-unit rules in Article 4 references). § 88.34.060 (and related two-unit provisions).

Plain-English synthesis and practical guidance

If your project is nonresidential and borders housing, plan to put a decorative masonry wall plus landscaping on the boundary; budget space for at least a 5‑ft planting strip (often 8 ft if next to parking) and trees at the code rates — this is a standard condition the review authority expects. § 88.30.020.G.1, § 88.34.050.D.3.d.
Design parking lots so that at least 10% of the paved area is planted and trees are distributed to provide future shade (1 tree per 5 spaces) and specify canopy trees from the city’s approved list on your landscape plan. § 88.34.050.D.4.
For any new development or significant change (≥~25% of floor area) submit a preliminary and a final landscape plan prepared by a licensed landscape professional and be prepared to post landscape surety if the director requires it. § 88.34.020.
Fence and wall heights are measured from the lowest adjacent grade; be careful on sloped lots (retaining wall + fence combined height rules and minor-use permit options apply). § 88.30.020.B.3.

Practical links in the process (first natural mention):

If you have parking changes, factor in the city's parking landscaping requirements and consult the Azusa Parking page early.
Landscaping and screening are part of design review in many districts — consult the Azusa Design Review guidance and expect site-level conditions.
Overlays can change screening/setback rules (for example the DNT overlay) — check the Azusa Overlay Districts when you locate your parcel.
Plant lists and other development standards are tied to the Azusa Development Standards and the city’s approved plant list (city engineer/community services); verify species selection.
Special perimeter or pool fencing references the California Building Standards Code (Title 24) for safety-related fences around pools; the code defers those technical requirements to that code. § 88.30.020.E.6.
If you are proposing an ADU, screening and landscape standards in the underlying zone apply; see Azusa ADUs and the development standards chapter.

Checklist (what an applicant must satisfy)

Confirm applicable zone/overlay for the parcel (Article 2 map) and whether any special purpose zone or overlay modifies screening rules. Verify with the jurisdiction.
Prepare a Preliminary Landscape Plan with species, sizes, locations and irrigation for review (required with planning applications). § 88.34.020.A–C.
Prepare a Final Landscape Plan prepared by a licensed landscape professional and get director approval before grading or building permit. § 88.34.020.B–D.
Provide required parking-lot landscaping (≥10% interior planting; 1 tree per 5 spaces) and perimeter planting (1 tree per 25 ft) where applicable. § 88.34.050.D.4 / D.3.
If the project abuts residential, include the screening wall/fence (masonry decorative wall typically 6 ft) and planting strip (5 ft or 8 ft) as required, or request a waiver with justification. § 88.30.020.G.1, § 88.34.050.D.3.d.
Check fence/wall material rules (no perimeter wood fences except limited circumstances; barbed wire generally prohibited except in DW per director approval). § 88.30.020.F.
Provide plans showing how landscape heights observe traffic-sight visibility areas (no more than 42 in in visibility triangles except allowed tree canopies). § 88.34.060.A.3.
Budget for surety if required (150% of plant/irrigation/installation for two years) if the director requests. § 88.34.020.E.

Risks & Ambiguities

Issue	Why it matters	What to verify
Exact zone/overlay boundary for parcel	Screening/setback exceptions and fence heights change by district/overlay	Verify zone and overlays on the official zoning map and consult Article 2; verify with Planning. Not found in retrieved materials (zoning map).
Which plant species are “approved”	Code requires the city’s approved plant list and drought-tolerant selection; using disallowed species can trigger rework	Request the city's approved plant list from Community Services / City Engineer; the requirement appears in § 88.34.060 and related plan rules.
Combined retaining wall + fence height over slopes	Height is measured from lowest grade; combined height caps and minor-use permit thresholds apply	Confirm field measurement method with the director; see § 88.30.020.B.3 and § 88.30.020.D.
When screening may be waived or substituted	Review authority may approve alternatives when intent is met	If site constraints or compatibility issues exist, request waiver and provide alternative mitigation per § 88.30.020.G.1.e.
Applicability to ADUs or very small projects	Some requirements apply only to new development or “significant expansion”	Verify whether your ADU or small project meets the thresholds in § 88.34.020 for required landscape plans.

Frequently asked questions

Do I always need a landscape plan for a small remodel in Azusa?

If your project is a new development or a “significant expansion” (the code uses thresholds, e.g., ~25% or other director-determined thresholds), you must submit a preliminary landscape plan with the planning application and a final plan before building/grading permits. Check § 88.34.020 and verify with the director whether your remodel meets the threshold.

What fence height can I build on a typical R‑1 (residential) lot in Azusa?

The code sets common maximums: 42 inches in required front setbacks and 6 feet in side and rear setbacks; fences outside required setbacks may be taller up to the maximum building height. Height is measured from the lowest adjacent grade; special exceptions and minor-use permit modifications exist. These are in § 88.30.020.

If my commercial parking lot borders homes, what screening is required?

A nonresidential parking area adjoining a residential use must provide a minimum 10‑ft landscaped buffer between parking and the common property line, a solid decorative masonry wall/fence (except for approved pedestrian access), and trees at the rate of one per 25 linear feet. See § 88.34.050.D.3.d.

Can the city require a masonry wall instead of plants?

Yes. When a commercial/industrial use abuts a neighborhood zone, the required screen is plant materials plus a solid decorative masonry wall of about 6 ft (up to 8 ft if allowed by height limits); the review authority may approve alternatives or waive requirements if equivalent mitigation is demonstrated (see § 88.30.020.G.1).

Are wood fences allowed along my property perimeter?

Perimeter wood fences are generally prohibited except for limited cases (e.g., wood fences ≤ 42 in in front/street side setbacks, or rail fences at equestrian facilities). Chain link visible from public rights-of-way is also restricted. See § 88.30.020.F for allowed/prohibited materials.

What are the parking-lot tree requirements in Azusa?

Interior parking landscaping must total at least 10% of the parking lot area and include trees at a minimum ratio of one tree per five parking spaces; required shade trees must be from the city’s approved canopy list and planted at minimum specified sizes. § 88.34.050.D.4.

Do perimeter masonry walls need design features?

Yes. Perimeter masonry walls visible from public rights-of-way must include articulation — for every 15 feet of continuous wall provide an 18‑inch deep by 3‑ft long landscaped recess or other approved design element; pilasters are required at changes of direction and at least every 25 ft. § 88.30.020.E.4.

If my lot is sloped, how is fence height measured?

Fence height is measured from the lowest natural grade within six feet of the base; where a fence sits on a retaining wall there are combined-height caps and minor-use permit routes for higher combined heights. See § 88.30.020.B.3 and related subsections.

Are rooftop HVAC units required to be screened?

Yes. Roof- and ground-mounted mechanical equipment must be screened from public view and from abutting residential zones as determined feasible by the review authority; the screening method must be architecturally compatible. § 88.30.020.G.2.

Will the review authority accept alternatives to a masonry wall?

Potentially. The review authority may waive or approve substitute screening methods if the relationship of uses or site characteristics make the standard screening unnecessary, or if an alternative meets the intent, per § 88.30.020.G.1.e. Always provide justification and comparative mitigation in your submittal.
