Dorris — Landscaping and Screening

Q: What are the allowable fence heights in Dorris?

In general the city limits fences and walls to 4 feet in the front yard setback area and 6 feet in rear and side yard areas (measured from the uphill side on slopes); administrative exceptions allow up to +2 ft in some slope/privacy situations subject to review — § 18.84.130 .

Q: Do RV parks or manufactured home parks have special screening rules?

Yes. RV parks must provide perimeter screening at least 6 ft high (unless spaces are not visible from the roadway), per‑space landscaping minimums (10% or 200 sq ft) and at least one tree per space; manufactured home parks must have at least 5 ft of landscaped yard adjoining property lines and the city may require additional fences or screening — § 18.84.080 and § 18.84.060 .

Q: Can I add lattice or decorative open material on top of a fence to increase height?

Yes; lattice or decorative wrought iron that is at least 50% open may be added to the top of a fence or wall where reviewed as compatible by the city clerk/designee. However, this does not automatically bypass height, safety, or visibility rules — § 18.84.130 K2 .

Overview

This page summarizes what the City of Dorris zoning and planning ordinance requires specifically for landscaping and screening (fences, walls, hedges, planting and perimeter screening). It stays strictly to provisions in the Dorris municipal zoning text (Title 18 / related chapters) and explains how the rules are applied across the city’s zoning districts. Where the code is silent, the entry notes that the item was Not found in retrieved materials and advises verification with the city.

Key code themes (short)

Fences/walls/hedges/equivalent screening require an administrative fence permit and are height‑limited: 4 feet in front setback areas (except limited exceptions) and 6 feet in side/rear areas unless otherwise allowed; special rules for slopes, corners, and safety apply — § 18.84.130 .
Minimum landscape in development contexts: front setbacks must be landscaped and include one 15‑gallon tree per 50 feet of frontage and one 1‑gallon shrub per 5 feet of frontage; irrigation and maintenance required — see the landscaping rules in the site/development standards (various development chapters) and supporting design standards — § 18.56.070 / development chapters referencing landscaping and § 18.68.090 for parking lot landscape standards .
Manufactured home parks, RV parks and multifamily projects have tailored landscape/screening rules (per‑park perimeter screening, minimum landscaped areas, trees per space) — see the specific special provisions for each use — § 18.84.060, § 18.84.080, § 18.84.090 .

When the page mentions related implementation topics, the first natural mention links to the City menu pages: parking, development standards, design review, overlays, ADUs, signage, and the state building code. For example: the parking rules that trigger parking-lot landscaping are in Dorris Parking, and front/setback dimensional triggers live in Dorris Development Standards.

Parking: Dorris Parking
Development standards: Dorris Development Standards
Design review: Dorris Design Review
Overlay rules: Dorris Overlay Districts
Accessory dwelling units: Dorris ADUs
Signs: Dorris Signage

District-by-district breakdown (where landscaping/screening rules appear)

Note: below each district heading I list the district name exactly as used in the Dorris code and the most relevant landscaping/screening rules that apply to developments in that district, with the controlling code citations.

R-L (Residential Low)

Purpose & typical uses: low‑density single‑family and accessory uses; accessory dwelling units allowed per chapter 18.104. Uses table identifies fences and walls as permitted accessory structures subject to fence rules — R-L is bolded as a district label in the code. See uses and accessory lists in the district table .
Key dimensional standards: front yard 20 ft minimum, side yards 5 ft interior, exterior side 15 ft, 35 ft height caps for primary structures (see Development Standards) — these dimensional standards are in the R‑district development tables and control where landscaping goes; see Dorris Development Standards and § 18.20.060 .
Landscaping & screening notes: fences/walls on R‑L lots must comply with § 18.84.130 (administrative fence permit, 4 ft max in front setback areas, 6 ft elsewhere) and vegetation in setbacks is subject to setback rules and the California Solar Shade Control Act — see § 18.84.130 and § 18.84.200 .
Where it applies: citywide residential neighborhoods zoned R-L.

R-M (Residential Medium)

Purpose & typical uses: medium density housing (duplexes, small multiunits) with accessory uses; accessory structures (including fences/walls) called out as permitted with compliance to fence standards — see district tables .
Key dimensional standards: district development table prescribes lot widths and setbacks (refer to Development Standards) that determine required front yard landscaping; fences subject to § 18.84.130 .
Landscaping & screening notes: multifamily projects of 5+ units must meet open space and landscaped area requirements; front setback planting formula (one 15‑gallon tree per 50 ft frontage; one 1‑gallon shrub per 5 ft) applies to projects when a site plan is required — see the development/site plan provisions and the multifamily open space rule § 18.84.090 and site plan landscaping rules .

R-H (Residential High)

Purpose & typical uses: higher density residential and multifamily; same accessory‑fence treatment as other residential districts — fences/walls permitted as accessory uses subject to § 18.84.130 .
Key dimensional standards: R‑H district tables show lot coverage, setbacks and higher height limits where applicable; these influence landscape area calculations — see district development tables and site plan landscaping rules .
Landscaping & screening notes: multifamily open space landscaping and parking lot landscaping requirements apply; irrigation/maintenance obligations explicitly required where landscaping is provided — see § references in the development sections .

R-1 / R-2 and other single/multi family districts

R‑1 (Low Density Single Family) and R-2 (Medium Density) follow the same cross‑references: fences/walls are permitted accessory structures but must follow § 18.84.130; front-yard landscaping requirements appear in site plan/development standards when new projects or subdivisions are reviewed — see § 18.20.060, § 18.24.060, and the general landscaping rules in the Special Provisions chapter .

C-1 / C-2 (Commercial districts) and MU-1 (Mixed-use)

Purpose & typical uses: commercial uses, mixed use, and some residential allowed; accessory fences and walls permitted subject to § 18.84.130; commercial projects triggering parking requirements must provide parking lot landscaping consistent with the off‑street parking design standards — see Dorris Parking and § 18.68.090 referenced in the development sections .
Landscaping & screening notes: commercial perimeter fencing along public streets has material restrictions (decorative iron, pre‑painted welded steel, vinyl, or wood picket) and barbed wire/chain link is prohibited for perimeter frontages — see the development standards referencing fencing and § 18.84.130 .

M (Manufacturing / Industrial)

Purpose & typical uses: light industrial, garden centers, storage, and related uses; the M district explicitly allows uncovered storage on rear lot areas when screened by solid fencing at least six (6) feet in height — see 17.44.030(C) and the cross‑reference to § 18.84.130 for fence standards .
Landscaping & screening notes: industrial uses that store materials in the open are required to screen those areas with the solid fence minimum height stated above; other project landscaping follows site plan requirements.

P-A (Public Agency) and P-D (Planned Development)

P‑A: public uses and parks; accessory fences/walls must comply with § 18.84.130; public facilities and parks often trigger landscape and open‑space rules in their development standards — see 18.52.030 .
P‑D: planned developments are reviewed as a whole; the P‑D process requires submission of a development plan that includes landscaping and utilities and allows the city to set or alter landscaped area requirements as part of the development standards — see § 18.56.050 and the site plan content requirements (landscaped areas must be shown) .

Special‑use rules (manufactured home parks, RV parks, multifamily)

Manufactured home parks: require no less than 5 feet of landscaped yard adjoining each property line; the city may require additional landscaping or fences/walls where needed to screen or buffer — § 18.84.060 .
RV parks: minimum landscaped area per RV space (10% or 200 sq ft, whichever is greater), at least one tree per space, overall park minimum landscaped area 20%, and perimeter screening at least 6 ft unless spaces are not visible from the street — § 18.84.080 .
Multifamily: developments of 5+ units must provide open space and landscape improvements; recreation areas visible from units must be shielded from streets/parking with a fence/barrier at least 4 ft high — § 18.84.090 and related site plan landscaping rules .

Practical guidance / plain‑English interpretation (original synthesis)

If you are building a new fence, plan for an administrative fence permit and submit a site plan showing fence location, elevations and heights. The city enforces 4‑ft front yard visibility and 6‑ft side/rear heights as the default maximums, and will refuse materials that are unsafe or visually offensive — see § 18.84.130 .
For any project that requires a site plan (multiunit, commercial, RV park, manufactured home park, planned development), include a landscape plan that shows the front‑setback tree and shrub counts, irrigation, and a maintenance plan; dead plant replacement is explicitly required — see the landscaping requirements included in site‑plan/development sections .
For parking areas, follow the off‑street parking rules because parking‑lot landscaping is enforced through the parking chapter and referenced in the landscape sections — see Dorris Parking and § 18.68.090 .
Use material and style variation at long perimeter walls to avoid monotonous solid walls (the code encourages variation), and avoid chain link and barbed wire where the property fronts a public street — § 18.84.130 and project standards .

Checklist (what an applicant must provide / satisfy)

Prepare a scaled site plan showing property dimensions, all structures, driveways/streets, and the proposed fences/walls with elevations and heights (site plan content required for fence permit) — § 18.84.130 .
Apply for the Administrative Fence Permit before construction (permit is required for any fence/wall) — § 18.84.130 .
For projects with required front setbacks, provide landscape plan showing one 15‑gallon tree per 50 ft frontage and one 1‑gal shrub per 5 ft frontage, irrigation, and a maintenance/replacement plan — site plan/development standards .
For parking areas, include parking‑lot landscaping per § 18.68.090 and show plantings on the site plan; include location/type of exterior lighting as part of the landscape plan — § 18.68.090 referenced in development sections .
If proposing fence/wall heights above the default limits (e.g., slope or privacy justification), prepare the slope/grade justification and expect consultation with fire, police, and public works and neighbor notification (administrative or discretionary review may be required) — § 18.84.130 K .
For RV parks, manufactured home parks, and multifamily projects, include the specific landscaped area calculations required by their chapters (e.g., RV park per‑space and overall minimums; manufactured home park perimeter landscaping) — § 18.84.080, § 18.84.060, § 18.84.090 .
Verify whether Design Review or Planned Development approval is required for your project and include landscape/screening elements in those submittals — see Dorris Design Review and P‑D requirements § 18.56.070 .

Risks & Ambiguities

Issue	Why it matters	What to verify
Slope height add‑on for fences (up to +2 ft)	The code permits a limited height increase to maintain privacy on sloped lots, but it triggers administrative review and neighbor notification — noncompliance risks permit denial or appeal — § 18.84.130 K	Verify grade measurement method, submit topo/site docs, and confirm the review timeline and required notifications with planning staff.
Corner lot visibility triangle	Corner visibility reduces allowed fence/hedge height to 3 ft within the defined triangle to protect traffic sightlines; failure causes public-safety objections — § 18.84.130 L	Verify triangle dimensions on your parcel; confirm whether a use permit is feasible for taller screening.
Nonconforming fence replacement threshold	Ordinary repairs allowed, but replacement >50% in one year requires full compliance — could force retrofit of older fences — § 18.84.130 M	Confirm how much of your current fence is nonconforming and whether replacement triggers compliance.
Plant species / fire risk / clearance	The zoning code requires landscaped areas and replacement of dead plants, but does not supply a species list or WUI clearance specifics (fire rules may be in fire code/Title 24 or local Fire Authority rules)	Not found in retrieved materials — Verify with the Fire Department, local planning, and California wildland‑urban interface guidance; see California Building Standards Code.
Applicability across zoning districts	Many landscape standards are invoked only when a site plan or project review is required (multifamily, RV parks, commercial). Single‑lot homeowners may be uncertain whether the tree/shrub formula applies.	Confirm with Planning whether your project is considered a “site plan” submittal or a ministerial building permit only; verify with staff.
Screening chapter text missing	The table of contents lists § 18.84.250 Screening, but full operative text for that section was Not found in retrieved materials	Not found in retrieved materials — Verify the content of § 18.84.250 with the city clerk or planning counter.

Plain‑English summary

If you're adding landscaping, a new fence, or designing a site in Dorris, expect to show a landscape plan with front‑yard tree and shrub counts, to get an administrative fence permit for any fence or wall, and to follow the city’s height limits: generally 4 ft in front yard areas and 6 ft elsewhere (with limited slope and special‑use exceptions). Specific project types (RV parks, manufactured home parks, multifamily, commercial) have additional numeric landscape/screening rules you must show on the site plan — see the cited sections for the exact text and confirm parcel‑level applicability with Planning. § 18.84.130 and the site‑plan/development rules are the controlling places to start .

Frequently asked questions

What are the allowable fence heights in Dorris?

In general the city limits fences and walls to 4 feet in the front yard setback area and 6 feet in rear and side yard areas (measured from the uphill side on slopes); administrative exceptions allow up to +2 ft in some slope/privacy situations subject to review — § 18.84.130 .

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

Yes. An administrative fence permit is required before installing any fence or wall; the site plan and fence elevation must be submitted per the fence section requirements — § 18.84.130 .

What planting do I need in the front yard for a new development?

The code requires that front setback areas be landscaped and, where the site plan rules apply, include one 15‑gallon tree per 50 feet of frontage and one 1‑gallon shrub per 5 feet of frontage; irrigation and replacement of dead plants are required — site plan/development standards (see landscaping requirements) .

Are chain link and barbed wire fences allowed along streets?

Barbed wire and chain link fencing are prohibited for perimeter fences along public streets; perimeter fencing along a public street should be decorative iron, pre‑painted welded steel, vinyl, or wood picket material as specified in project standards — development provisions referencing § 18.84.130 .

Do RV parks or manufactured home parks have special screening rules?
