Gridley — Landscaping and Screening

Q: What fence heights are allowed in residential zones?

In residential zones fences are generally limited to 7 ft in side/rear yards and 3 ft in the front yard; 4 ft can be allowed in front yards if the fence maintains at least 40% open area , and an administrative permit can allow 8 ft where lots have grade differences (measured from the lower lot) § 17.72.040(A–B) .

Q: Do non‑residential sites need walls when next to homes?

Yes. The code requires a minimum 6‑ft solid block wall along rear and side property lines where a non‑residential property abuts property zoned or used for residential uses; the Planning Department reviews these walls § 17.72.040(C) .

Q: What are the front‑yard landscaping requirements for new houses?

For new dwellings, the entire front yard must be landscaped , include underground irrigation , and have at least one shade tree from the City’s approved list in a five‑gallon container prior to final inspection/occupancy § 17.78.020(B)(b) . Also, impervious surfaces between the dwelling and the street may not exceed 50% of the front yard § 17.78.020(B)(c) .

Q: Does Gridley explain how to measure fence height on sloped lots?

Yes: the admin exception allowing up to 8 ft is measured from the ground level of the lower lot at the property line; applicants should verify grade points with staff and may need a site survey § 17.72.040(A)(2) .

Overview

This page summarizes what the City of Gridley’s zoning ordinance requires for landscaping and screening (fences, walls, buffers, trees) across the city’s zoning districts. It is based on the adopted Title 17 zoning provisions: requirements for site development landscaping plans, residential front‑yard landscaping, fence heights/materials, parking-area landscaping and screening, and district-level expectations for commercial and industrial projects. Where the code authorizes Planning Commission or administrative review, the applicable § is cited so applicants can locate the exact text and staff interpretation. See the Gridley zoning overview to orient the parcel to a district. (/us/california/gridley/zoning)

District-by-district subsections that name the district and the landscaping/screening rules that apply there.
A decision‑relevant standards table and a short practical checklist for applicants.
Risks, ambiguities and things to verify with the Planning Department.

Citywide basics (applies to most developments)

A landscape and irrigation plan is a mandatory element of any Site Development Plan (SDP) application; the SDP requirement applies to residential, commercial and industrial development projects subject to site development review § 17.07.020 . (For small projects that are exempt from SDP, see the exemptions in § 17.07.040; verify with staff.)
Fence permits are required to erect, extend, modify, or in many cases repair fences; the permit process and conditions are in § 17.72.041–17.72.043 .
Materials and barbed/razor wire restrictions, maintenance obligations, and height exceptions are regulated in § 17.72.044 and § 17.72.050 .
Off‑street parking areas for non‑residential uses must include landscaping and fencing where they abut residential zones; the parking landscaping standards appear in § 17.76.070 . (If your project triggers parking review, consult the City’s Parking page.) (/us/california/gridley/parking)
Non‑residential projects that abut residential properties are required to provide a minimum six‑foot solid block wall on the rear and side property lines in those locations § 17.72.040(C) .

Note: many district chapters also repeat or add landscape requirements as part of site development review; see the district subsections below.

District-by-district requirements

The code typically layers a district’s use and yard rules with the site development plan (SDP) and Chapter 17.72 (fences/hedges) and Chapter 17.76 (parking landscaping). Below are the districts where landscaping/screening requirements are explicit in Title 17.

AR-5, R-S, R-1, R-2, R-3, R-4 (residential districts)

Purpose / typical uses: single‑family and multi‑family residential (see district tables in Title 17). For zoning maps and precise use tables start at the Gridley Zoning page. (/us/california/gridley/zoning)
Key landscaping/screening standards:
- Entire front yard must be landscaped for new dwelling units; an underground irrigation system and at least one shade tree (from the City‑approved list, in a minimum five‑gallon container) are required prior to final inspection/occupancy § 17.78.020(B)(b) .
- Front‑yard impervious surfaces (walkways, parking, driveways) may not exceed 50% of the front yard area between the house and the street § 17.78.020(B)(c) .
- Fence height in residential districts: side/rear: up to 7 ft; front yard: up to 3 ft (with an option for 4 ft if “clear visibility” (≥40% open area) is maintained). An administrative permit can allow up to 8 ft where grade differences between contiguous lots justify it; measurement is from the lower lot at the property line § 17.72.040(A) .
Where it applies: any new dwelling or redevelopment that requires a building permit or SDP; landscaping items are enforced at final inspection § 17.78.020 .

C-1 (Neighborhood Commercial) and C-2 (General Commercial)

Purpose / uses: commercial services and retail (see Chapter 17.36 and 17.32/17.34 for permitted uses). (/us/california/gridley/land-use)
Key landscaping/screening standards:
- A detailed landscape plan must be approved by the Planning Commission as part of site development review prior to building permits § 17.32.125 (C‑1) and § 17.34.125 (C‑2) .
- Off‑street parking serving commercial uses must be landscaped compatibly and when abutting residential zones require a solid 6‑ft wall § 17.76.070(A–B) .
Where it applies: commercial redevelopment, new commercial buildings and parking expansions (site development review required) § 17.34.120 / 17.32.120 .

(If your commercial project is in the central business combining zone, additional parking/compliance rules may apply; see the Gridley Parking page.) (/us/california/gridley/parking)

M-1, M-2, M-3 (industrial districts)

Purpose / uses: light to heavy industrial and agricultural industrial uses (see Chapter 17.42, 17.44, 17.46 for permitted uses).
Key landscaping/screening standards:
- Industrial development requires a site development plan and detailed landscape plan approved by the Planning Commission prior to permits § 17.42.125, § 17.44.125, § 17.46.125 .
- Where industrial or parking areas abut residential zones, the code requires landscaped side/rear yards (M‑districts include minimum landscaped yard widths in the yard subsections) and 6‑ft solid block walls for non‑residential properties abutting residential uses § 17.42.030 (yards) and § 17.72.040(C) .
Where it applies: new industrial development, expansions and site redevelopment; site development review applies § 17.42.110 / 17.44.110 / 17.46.110 .

Planned Development (PD) / Mixed Use (MUCZ)

The PD/Mixed Use combining provisions require the SDP and may require detailed landscape and maintenance plans as part of PD approvals § 17.55.080–17.55.090 .
Where it applies: projects approved as Planned Developments or using the Mixed Use Combining Zone; landscaping can be tailored as conditions of approval and maintenance covenants are commonly required § 17.55.090(I) . (If your site is in an overlay district check the Overlay rules; see the Gridley Overlay Districts page.) (/us/california/gridley/overlay-districts)

Decision‑relevant standards (quick reference table)

Topic	Key standard (bold where controlling)	Code reference
Fence height — residential side/rear	7 ft maximum (side/rear); 3 ft in front yard (4 ft allowed with 40% openness)	§ 17.72.040(A–B)
Administrative fence exception	Up to 8 ft between lots with grade differential (measure from lower lot)	§ 17.72.040(A)(2)
Non‑residential abutting residential	6‑ft solid block wall required on side/rear property lines	§ 17.72.040(C)
Fence permits	Permit required to erect/extend/modify fences; plan and fee required	§ 17.72.041–17.72.042
Fence materials/prohibitions	Durable materials only; no unfinished plywood, corrugated metal, exposed barbed/razor wire except per exceptions	§ 17.72.044
Parking landscaping / screening	Parking abutting residential: 6‑ft solid wall; parking areas must be landscaped and approved	§ 17.76.070(A–B)

Practical guidance / how it is applied

If your project is anything other than minor home repairs, expect to prepare a landscape and irrigation plan as part of your SDP packet § 17.07.020(B)(1) . The Planning Commission normally reviews these plans for commercial, industrial and many multi‑unit residential projects § 17.07.020(A) . (If your project is design‑sensitive, check whether it also needs design review.) (/us/california/gridley/design-review)
For single‑family homes: include irrigation details and plan to plant one approved shade tree in the front yard before final inspection § 17.78.020(B)(b) .
For commercial and industrial sites adjacent to residences, plan a 6‑ft solid wall and compatible planting on the non‑residential side, and include landscape maintenance language in tenant/owner agreements if the site will have multiple occupants § 17.72.040(C) .
For parking lots: show perimeter planting, interior islands and any required wall fencing; the Planning Department or Planning Commission approves the landscape/planting layout § 17.76.070(B) . (Coordinate with the City’s parking standards for stall counts and layout.) (/us/california/gridley/parking)
For fences: submit a fence permit plan showing location (outside public right‑of‑way), height, materials and relationship to neighbors. Barbed/razor wire is tightly restricted and allowed only in certain industrial districts or with permits and distance restrictions from residences/public roads § 17.72.044 .

Checklist (what an applicant must usually provide)

Confirm zoning district using the Gridley Zoning map and land‑use table (/us/california/gridley/zoning).
If subject to SDP, prepare a Landscape & Irrigation Plan (plans must show plant sizes, species, irrigation method, maintenance responsibility) § 17.07.020(B)(1) .
If new dwelling: include underground irrigation and one shade tree (five‑gallon min) in front yard, and ensure front‑yard impervious area ≤ 50% § 17.78.020(B) .
If property abuts residential zones and is non‑residential or has parking, show 6‑ft block wall on plans § 17.72.040(C) and § 17.76.070(A) .
Submit fence permit application for new/modified fences; include material and height details § 17.72.041–042 .
If proposing barbed wire or razor wire, document district eligibility, visibility setbacks and any administrative permits § 17.72.044(A) .
Coordinate with the Planning Department on whether Planning Commission approval is required (most commercial/industrial SDP landscaping plans) § 17.07.020(A) .
Verify overlay or historic‑district standards if the parcel is in an overlay — overlay rules can change screening or materials (see Overlay Districts) (/us/california/gridley/overlay-districts).
Verify any ADU landscaping or setback interactions with the ADU rules if adding an accessory unit (/us/california/gridley/adu).

Risks & Ambiguities

Issue	Why it matters	What to verify
"City‑approved list of trees" referenced for front yards	The code requires a tree from that list but does not include the list text in the zoning excerpt	Verify the City’s adopted tree list and minimum plant sizes with Planning/Building; the list is not in the retrieved materials Not found in retrieved materials (see § 17.78.020(B)(b))
Exact planting densities and species for commercial/industrial landscape plans	Title 17 requires a detailed plan but does not spell out species/density standards	Verify whether the Planning Department has a planting palette, water‑budget or drought‑tolerant requirements; the code language is general § 17.07.020(B)(1)
Measurement of fence height where lots differ in grade	Code measures fence height from the lower lot at the property line for the 8‑ft administrative exception — field measurement can affect compliance	Confirm how the City measures grade at the property line and whether a civil‑engineer topo is needed § 17.72.040(A)(2)
Barbed wire and razor wire allowances	The code prohibits barbed wire generally but lists district exceptions and requires permits when visible to residences or within 20 ft of a public road	Confirm if your parcel is within the limited districts (M‑1, M‑2, M‑3, C‑2) and whether additional permits are required § 17.72.044(A)
Relationship between SDP landscaping approval and building permits	Landscaping is approved at SDP and must be installed prior to final occupancy for many projects; timing and bonding may be required	Verify whether the Planning Commission will require security, phasing or maintenance covenants § 17.07.020 / 17.55.090
Overlay or historic district rules affecting materials	Overlay or historic preservation rules may alter allowable fence/wall materials or require different plant palettes	Check Overlay District and Historic Preservation provisions if applicable — these are not fully reproduced here (verify with the City) (/us/california/gridley/overlay-districts) (/us/california/gridley/historic-preservation)

Plain‑English summary

Gridley’s zoning code generally requires a written landscape and irrigation plan for most new development, mandates front‑yard landscaping (including an irrigation system and a shade tree) for new homes, restricts fence height and materials in residential areas, and requires 6‑ft walls and compatible planting where non‑residential parking or uses meet residential property lines; fence permits and Planning Department or Planning Commission approval are central to getting landscaping and screening approved § 17.07.020, § 17.78.020, § 17.72.040, § 17.76.070 .

Frequently asked questions

What landscaping plan do I need for a commercial project in Gridley?

Commercial projects that require Site Development Plan review must include a detailed landscape and irrigation plan as part of the SDP application; the plan is reviewed by staff and, for larger projects, the Planning Commission § 17.07.020(B)(1) . Also, many commercial district chapters (C‑1, C‑2) explicitly require Planning Commission approval of the landscape plan § 17.32.125; § 17.34.125 .

Do I need a permit to build a fence in Gridley?

Yes. A permit from the Planning/Building Department is required to erect, extend, or modify fences; applications must show location, materials and relationship to neighboring structures and rights‑of‑way § 17.72.041–042 .

What fence heights are allowed in residential zones?

In residential zones fences are generally limited to 7 ft in side/rear yards and 3 ft in the front yard; 4 ft can be allowed in front yards if the fence maintains at least 40% open area, and an administrative permit can allow 8 ft where lots have grade differences (measured from the lower lot) § 17.72.040(A–B) .

Do non‑residential sites need walls when next to homes?

Yes. The code requires a minimum 6‑ft solid block wall along rear and side property lines where a non‑residential property abuts property zoned or used for residential uses; the Planning Department reviews these walls § 17.72.040(C) .

What are the front‑yard landscaping requirements for new houses?

For new dwellings, the entire front yard must be landscaped, include underground irrigation, and have at least one shade tree from the City’s approved list in a five‑gallon container prior to final inspection/occupancy § 17.78.020(B)(b) . Also, impervious surfaces between the dwelling and the street may not exceed 50% of the front yard § 17.78.020(B)(c) .

Are there special rules for parking‑lot landscaping or screening?

Yes. All off‑street parking areas for non‑residential uses must be accompanied by landscaping and fencing; when parking abuts residentially zoned property a 6‑ft solid wall is required and parking landscaping must be compatible with the facility, subject to Planning Department/Planning Commission approval § 17.76.070(A–B) .

Can I use barbed wire or concertina wire on my fence?

Barbed/razor wire is generally prohibited in the City except in limited districts (M‑1, M‑2, M‑3, C‑2) and subject to restrictions; visible uses near residential properties or within 20 ft of public roads typically require an administrative permit § 17.72.044(A) .

What happens if I landscape differently than the approved plan?

The SDP approval and any conditions attached (including required walls, plant palette, irrigation and maintenance obligations) are enforceable; failure to install required landscaping or fencing can lead to denial of final occupancy or corrective actions per the municipal code (SDP conditions and fence permit enforcement) § 17.07.020; § 17.72.043 .

Does Gridley explain how to measure fence height on sloped lots?

Yes: the admin exception allowing up to 8 ft is measured from the ground level of the lower lot at the property line; applicants should verify grade points with staff and may need a site survey § 17.72.040(A)(2) .

If my lot is in an overlay or historic district, do different landscaping rules apply?

Possibly. Overlay and historic‑preservation standards may alter allowable materials, wall design, or planting palettes; check the applicable overlay provisions and the Historic Preservation chapter and confirm with Planning staff (/us/california/gridley/overlay-districts) (/us/california/gridley/historic-preservation).
