Corning — Landscaping and Screening

Q: What are Corning's fence height limits for a typical single‑family lot?

In Corning the general fence limits are 4 ft in the front yard and 6 ft in required side and rear yards; height is measured from the ground at the fence and exceptions may be authorized by the Technical Advisory Committee (TAC) for noise or glare reasons (sight distance and other conditions apply). § 17.50.150(B–C)

Q: When is a masonry wall required between properties?

The code requires solid masonry walls or equivalent to separate residential development from commercial and industrial development and between certain multi‑family and single‑family adjacencies; substitutes must include an acoustic certification. § 17.50.150(E)

Q: How close must trees be planted to the sidewalk on multi‑family projects?

For multi‑family projects the Code requires one tree per 20 ft of landscaped area between the right‑of‑way and buildings, with trees located 4–10 ft from the back of the sidewalk. § 17.12.070(A)(2)

Overview

This page summarizes what the City of Corning zoning ordinance requires for landscaping and screening (fences, walls, planting, parking lot landscaping, and buffers). It is based on the Corning Zoning Code (Title 17) and the multi‑family/design chapters; where the code requires verification or discretion, the guidance flags that. For the Code and broader context see the city's Corning zoning & planning overview and the Corning Zoning pages.

Key takeaways up front: residential multi‑family projects have detailed landscape, irrigation and screening rules (trees per linear feet and parking tree ratios), fence heights are capped in front/side/rear yards, and solid masonry walls (or acoustic equivalents) are explicitly required to separate residential uses from commercial/industrial uses in many situations (verify on a parcel basis). See the district-by-district breakdown below for where these standards apply.

How to read the citations

Every requirement below is grounded in the Corning Zoning Code and is followed by the controlling code citation (the § symbol and number) and the local file reference used to pull the text.

District-by-district breakdown (what matters for landscaping & screening)

Note: where a district's landscaping/screening rules were not present in the retrieved materials, the entry states "Not found in retrieved materials" and you should Verify with the jurisdiction.

R-2 (Single‑family / Multi‑family residential)

Purpose & where it applies: The R-2 district is intended for single‑family dwellings, duplexes, and small multi‑family and implements the SFR General Plan land use designation. § 17.13.010 .
Typical permitted uses: uses permitted in R-1 plus duplexes and triplexes; see § 17.13.020 for specifics. § 17.13.020 .
Landscaping & screening requirements:
- Multi‑family design standards apply (see Chapter 17.11 and 17.12) — landscaping around building perimeters is required, three‑tier plantings are encouraged, and irrigation must meet city water‑efficient rules. § 17.11.050 and § 17.12.070 .
- Parking lots serving multi‑family projects must include tree plantings and perimeter landscaping (tree ratios and a minimum 10‑ft perimeter strip, see table). § 17.12.070 .
Dimensional/installation highlights: private open space must be delineated by wall, fence, or hedge; fences in multi‑family projects must integrate building materials and may be required to be masonry in certain locations. § 17.11.050, § 17.12.090 .

Multi‑family (R-2, R-3, R-4) design guidelines

The multi‑family chapter (Chapter 17.11) establishes design and landscape expectations for R-2, R-3, and R-4 projects — site planning, perimeter landscaping, three‑tier plantings (groundcover/shrub/tree), irrigation, and lighting orientation are required. § 17.11.010—.050 .

OS-1 and OS-2 (Open Space districts)

OS-1: Purpose is primary open space (text present but landscaping specifics are general). § 17.36.010 Not found in retrieved materials for detailed plant/screen rules; Verify with the jurisdiction. .
OS-2: The OS-2 district explicitly lists parks, greenbelts, landscaped streets and scenic highways as permitted uses; open space design and low impervious coverage are emphasized. § 17.37.010—.050 .

Planned Development (PD)

PD districts allow project‑specific standards; landscaping and screening will be established as part of the PD approval. Where PD applies, the front/side/rear yard and coverage rules are set to match the underlying use and the PD permit will control landscaping/screening expectations. § 17.35.040—.050 .

P‑Q (Public / Quasi‑Public)

The P‑Q district is used for public, institutional and quasi‑public uses; site plan approval ensures compatibility and typically includes landscaped buffers and screening as a condition. § 17.33.010—.030 .

Commercial & Industrial zones (examples referenced in the code)

The Zoning Code references C‑3, CH, SPMU, M‑1 & M‑2 in multiple places (signage and visual guidelines). Where commercial/industrial zones abut residential uses, the Code requires solid masonry walls or equivalent sound/visual barriers. See § 17.50.150 (E) for wall requirements between commercial/industrial and residential uses. § 17.50.150 .

F (Frontage) and other combining districts

F (Special highway frontage combining district): may require screen planting or fencing for certain commercial uses as a condition of a use permit. § 17.42.020 .
Airport approach and other overlay height limits: trees and other natural growth are subject to height limits in airport zones; check § 17.02.040. § 17.02.040 .

Topic / standard	Rule	Code Reference
Front yard fence height	Max 4 ft in front yards (unless exception)	§ 17.50.150(B)
Side/rear yard fence height	Max 6 ft in required side/rear yards	§ 17.50.150(B)
Parking lot perimeter landscaping	Minimum 10 ft landscaped strip adjacent to public streets/property line; may be within setback	§ 17.12.070(A)(4)(b)
Parking lot tree ratio	At least 1 tree per 6 parking spaces; evenly distributed	§ 17.12.070(A)(4)(c)
Street‑front tree planting (multi‑family)	1 tree per 20 ft of landscaped area between ROW and buildings; placed 4–10 ft from back of sidewalk	§ 17.12.070(A)(2)

Fence materials in multi‑family	Walls: decorative masonry; fences: wood or vinyl; chain link prohibited	§ 17.12.090(A)
Retaining wall encroachment into city property	Encroachment permit required; building permit may also be required	§ 17.50.190

Practical guidance / plain‑English synthesis

If you propose a multi‑family project in R‑2/R‑3/R‑4, prepare a landscape plan that shows perimeter planting, a tree schedule (1 per 20 ft along ROW; 1 per 6 parking spaces in lots), irrigation compliant with the city’s water‑efficient landscaping rules, and lighting oriented away from neighbors. See § 17.11.050 and § 17.12.070. .
For single lots or single‑family yards, fences visible from the street are limited to 4 ft; side and rear yard fences up to 6 ft are allowed unless a special requirement applies (for example, when a masonry wall is required between uses). § 17.50.150 is the controlling fence standard.
Where a commercial or industrial development abuts residential property the Code typically requires solid masonry walls (or certified acoustic equivalents) as a condition of approval — anticipate this when designing site edges. § 17.50.150(E) .
Screening of mechanical equipment, meters, and refuse enclosures is required; refuse enclosures have minimum height and siting rules and must not be visible from rights‑of‑way. § 17.12.090(A) .
Decorative block walls may be allowed within front yard setbacks when screening is necessary, but they must be decorative masonry, capped, and include a landscape setback. § 17.12.090(A)(6) .

(If your project triggers design or site plan review, consult the city’s Corning Design Review page early. For parking‑related landscape coordination see the Corning Parking guidance and the Corning Development Standards. If your project involves an ADU, review the Corning ADUs rules alongside these landscape rules. Building code matters (fire separation of walls, structural design for retaining walls) fall under the California Building Standards Code and are not covered here.)

Show parking lot landscaping: 10‑ft perimeter strip (or note where within setback) and 1 tree per 6 spaces (§ 17.12.070(A)(4)(b–c))
Indicate all screens for mechanical equipment, meters, and refuse enclosures; refuse enclosures min 6 ft tall and out of view (§ 17.12.090(A)(7))
If the project abuts residential/commercial/industrial edges, include masonry wall details or acoustic equivalent and certification if applicable (§ 17.50.150(E))
Fence plan showing heights (front 4 ft, side/rear 6 ft) and materials; obtain building permit for fence per Title 15 (§ 17.50.150(A–B))

Risks & Ambiguities

Issue	Why it matters	What to verify
Masonry wall triggers and waivers	Code requires solid masonry walls between residential and commercial/industrial in many cases; waiver possible by Planning Commission for downtown or other specific findings	Verify whether your parcel triggers the masonry wall rule (see § 17.50.150(E)) and confirm whether a variance or commission waiver is needed.
Front yard block walls within setbacks	Code allows decorative block walls in front setbacks only when screening necessary and if decorative and setback with planting	Confirm allowed design and required landscape setback with planning staff; see § 17.12.090(A)(6).
Fence height exceptions (TAC authority)	TAC can authorize taller front‑yard obstructions for noise/glare — but sight distance and other conditions apply	If requesting higher fence, confirm TAC criteria and sight‑distance review with Public Works; see § 17.50.150(C).
District‑specific landscaping rules missing	Some district chapters do not contain explicit planting palettes or species lists	If a project is in a district where specific landscape standards were not retrieved, Verify with the jurisdiction (city planning) for local lists or specific plan requirements (e.g., Highway 99W specific plan). Not found in retrieved materials for some districts.
Trees in airport approach zones	Trees are limited by airport approach zone height rules — planting could violate height limits	If your parcel is in an airport overlay, confirm tree height allowances per § 17.02.040 before planting.

Plain‑English Summary

Corning's zoning code requires perimeter planting, parking‑lot trees, irrigation that meets water‑efficiency rules, and limits on fence heights (4 ft front, 6 ft side/rear). When commercial/industrial development borders homes, the city typically requires solid masonry walls or certified acoustic equivalents; multi‑family projects have more detailed landscape, lighting, and screening standards. Verify parcel‑specific triggers (masonry walls, TAC exceptions, overlay height limits) with the planning department. § 17.12.070, § 17.11.050, § 17.50.150.

Frequently asked questions

What are Corning's fence height limits for a typical single‑family lot?

In Corning the general fence limits are 4 ft in the front yard and 6 ft in required side and rear yards; height is measured from the ground at the fence and exceptions may be authorized by the Technical Advisory Committee (TAC) for noise or glare reasons (sight distance and other conditions apply). § 17.50.150(B–C)

Do I need a building or other permit to build a fence in Corning?

Yes — no fence shall be constructed prior to obtaining a building permit as provided in Title 15, except for rebuilding an existing fence to the same dimensions and materials. § 17.50.150(A)

When is a masonry wall required between properties?

The code requires solid masonry walls or equivalent to separate residential development from commercial and industrial development and between certain multi‑family and single‑family adjacencies; substitutes must include an acoustic certification. § 17.50.150(E)

What landscaping is required for multi‑family projects in Corning?

Multi‑family projects must provide perimeter landscaping, a three‑tier planting system (groundcover/shrub/tree), irrigation that complies with the city's water‑efficient landscaping regulations, and parking lot landscaping including a 10‑ft perimeter strip and 1 tree per 6 parking spaces. § 17.11.050, § 17.12.070

Are parking lots required to be screened from the street?

Yes — parking areas must be screened from view from public roadways with landscaping, berms (≤2 ft), hedges, walls, or some combination; a 10‑ft perimeter landscape strip is required adjacent to streets or property lines. § 17.12.070(A)(4)(a–b)

Can a block wall be constructed within a front yard setback?

When screening is necessary the Code allows block walls within a front setback only if they are decorative masonry with a decorative cap and include a landscape setback; use of such a wall is conditioned on these design qualities. § 17.12.090(A)(6)

How close must trees be planted to the sidewalk on multi‑family projects?

For multi‑family projects the Code requires one tree per 20 ft of landscaped area between the right‑of‑way and buildings, with trees located 4–10 ft from the back of the sidewalk. § 17.12.070(A)(2)

Are refuse enclosures regulated for screening?

Yes — refuse enclosures for developments with five or more units must be located in an enclosure or building, be at least 6 ft tall, and be designed and sited so they are not visible from public rights‑of‑way. § 17.12.090(B)(2–4,8)

What if my parcel is in an overlay or the Highway 99W specific plan area?

Specific plans and overlays (for example the Highway 99W corridor specific plan) add visual design and streetscape landscaping guidance; those rules apply in addition to Title 17 and can set more specific screening/streetscape expectations. See the specific plan chapters for details and site plan review requirements. § 17.53.020—.040

Do tree height rules apply near the airport?

Yes — in the airport approach zone the Code limits heights of structures and trees (e.g., max 15 ft at a specific approach distance) and allows variances only by the city council/planning commission for practical difficulty. Confirm with § 17.02.040—.050. ---
