San Fernando — Design Review

Q: Do I need design review (site plan review) for a 300 sq ft addition to my single‑family home in San Fernando?

Yes — a residential exterior alteration that adds 200 sq ft or more triggers a site plan review permit under § 106‑856(3) ; the director will review the plans for conformity to code, the general plan and any design guidelines before approval.

Q: What are the R‑1 setback and height standards I should design to?

The residential tables in § 106‑43 (Tables 106‑43.1/106‑43.2) list standard setbacks (front ~20 ft , rear 20 ft , side 5 ft ) and a maximum height of 35 ft for R‑1 homes; use these when preparing elevations and site plans. § 106‑43 .

Q: Does the SP‑5 specific plan area impose separate design rules?

Yes. Properties inside the SP‑5 San Fernando Corridors Specific Plan must follow SP‑5’s mandatory development standards and recommended design guidelines; the specific plan controls where it addresses an issue and is applied during site plan review per § 106‑135 and § 106‑133 . § 106‑133 , § 106‑135 .

Overview

In San Fernando the city’s zoning ordinance (commonly Title 17 / the San Fernando Zoning Ordinance) folds architectural and aesthetic control into two related review tracks: (1) a formal site plan review procedure for development that meets specific triggers, and (2) lower‑level administrative planning review for smaller changes and ministerial checks. The relevant rules and thresholds are contained in the Municipal Code (notably the site plan review divisions and the residential/overlay zone tables) and apply differently depending on whether a project is in R-1/R-2/R-3, M-1/M-2, RPD, PD/MU overlays, or the SP-5 specific plan area. See the San Fernando Zoning page for context and the city’s Development Standards for dimensional detail.

What the code requires (short syntheses, with controlling §§)

The core trigger list for when a formal site plan review permit is required is in § 106-856 (site plan review applicability). Typical triggers include residential additions ≥ 200 sq ft or adding a second story, commercial/industrial additions equal to 20% of existing square footage or ≥ 500 sq ft, work requiring a CUP/variance, and all new construction in certain overlays (PD, RPD, MU) or the SP-5 specific plan. § 106-856.
The application and processing steps (submittal requirements, completeness review, fees) and that the director reviews plans for conformity to the ordinance, general plan, specific plans, and any adopted design guidelines are in § 106-857 (procedure) and § 106-858 (application/completeness). § 106-857, § 106-858.
Approval of a site plan review requires specific findings for non‑housing and housing projects (what the review authority must find) in § 106-859; conditions to ensure conformity and mitigation (including CEQA compliance) are in § 106-860. § 106-859, § 106-860.
For smaller exterior changes, color/material updates, or other lower‑impact revisions, the director may process them via administrative planning review (minor or major) under § 106-844 to § 106-846; those items are explicitly listed (for example, residential paint or non‑form‑changing exterior materials). § 106-844–§ 106-846.
Where a specific plan applies (for example the SP-5 San Fernando Corridors Specific Plan), the specific plan’s development standards and design guidelines control; site plan/submittal requirements still apply, but the SP‑5 rules are mandatory where they exist. § 106-131 – § 106-136 and § 106-133 (SP‑5). § 106-135 requires discretionary approvals to be consistent with any specific plan.
Development agreements remain subject to architectural (design) reviews as provided in the Code (see § 106-1098). § 106-1098.

Note: the Code repeatedly ties design review to other topic areas (landscaping, parking, signage, historic resources). See the city’s pages on Parking, Signage, Historic Preservation, and Landscaping and Screening for parallel standards that the reviewer will use.

District-by-district breakdown (purpose, typical uses, key dimensional standards, where design review applies)

All district summaries below quote the code section that contains the rules; always verify parcel zoning on the official map.

R-1 (single-family residential)

Purpose / typical uses: Single‑family detached housing; density limited to 1 unit per lot in standard R‑1 development. See the lot/density table. § 106-43.
Key standards: Minimum lot size 7,500 sq ft, front setback ~20 ft, rear 20 ft, side 5 ft, max height 35 ft per the residential tables. § 106-43.
Design review application: Alterations that add ≥ 200 sq ft or add a second floor trigger site plan review under § 106-856(3); smaller material/color changes may be eligible for administrative planning review under § 106-846. § 106-856, § 106-846.

R-2 / R-3 (multi‑family residential)

Purpose / typical uses: R‑2 and R‑3 allow progressively higher densities (tables list the maximum density formulas), with R‑3 permitting the tallest heights (up to 45 ft). § 106-43.
Key standards: See TABLE 106‑43.1 and 106‑43.2 for lot sizes, setbacks, and heights (front 20 ft, side 5 ft, rear 15–20 ft depending on condition). § 106-43.
Design review application: Residential projects are subject to the standard site plan triggers; housing projects have separate findings in § 106‑859(2). § 106-859(2).

M-1 / M-2 (industrial)

Purpose / typical uses: Light and general industrial uses; the code requires most M‑1/M‑2 uses be inside permanent buildings and specifies site controls (landscaping, underground utilities, street frontage minimum). § 106-104.
Key standards: Required street frontage 75 ft, no outside storage except by CUP, exterior colors and lighting are subject to review (exterior colors reviewed with discretionary review). § 106-104.
Design review application: Commercial/industrial additions that enlarge floor area by ≥ 20% or ≥ 500 sq ft trigger site plan review (§ 106-856(4)), and exterior colors/elevations are reviewed when discretionary review is required. § 106-856(4), § 106-104(1).

RPD – Residential Planned Development Overlay

Purpose / typical uses: Allows planned development flexibility while staying within general plan density limits; emphasizes site planning and open space. § 106-163.
Key standards: RPD sets project‑level standards (minimum project area 2 acres, building height typically 35 ft / 2 stories, lot coverage caps, detailed setback tables in Tables 106‑165.1/2). § 106-165 (Tables 106‑165.1 & 106‑165.2).
Design review application: New construction or major remodel in the RPD triggers site plan review per § 106‑856(2); RPD projects are processed with concept plan review and conditional use permit per § 106‑166. § 106-856(2), § 106-166.

PD / MU Overlay zones

Purpose / typical uses: Purpose varies with the overlay; overlays alter standards or require additional approvals to allow mixed uses or planned development. See the overlay rules (Division 6). § 106-856(2) signals overlays where site plan review is mandatory for major work. § 106-163–§ 106-165 and overlay division.

SP‑5 San Fernando Corridors Specific Plan

Purpose / typical uses: Downtown/corridor revitalization plan with mandatory development standards and recommended design guidelines for Truman St, San Fernando Rd, Maclay Ave, First St. The SP‑5 standards are mandatory; guidelines inform design review. § 106-131 – § 106-136 and § 106-133.
Design review application: Projects inside SP‑5 follow the specific plan standards for development and are subject to site plan review when they meet the triggers in § 106‑856. § 106‑135, § 106‑856.

Quick decision‑relevant table

Issue / standard	What matters to design review	Code reference
Site plan review triggers (residential: 200 sq ft or 2nd floor; commercial/industrial: ≥20% or 500 sq ft; new construction in PD/RPD/MU/SP‑5)	Decides whether director or commission review and a formal site plan review permit are required	§ 106‑856

Procedure / submittal / fees	Number of plan copies, fees, completeness review, and no building permit until approved	§ 106‑857, § 106‑858
R‑zone lot/setback standards (R‑1/R‑2/R‑3)	Lot size, setbacks, heights that design reviewers check for compliance	§ 106‑43 (Tables 106‑43.1 / 106‑43.2)
RPD project standards (setbacks, lot coverage, parking)	RPD requires project‑level standards and concept review before CUP	§ 106‑165 (Tables 106‑165.1/2)

Checklist — what an applicant must provide to clear design review / site plan review

Completed application and the number of plan copies required by the director; application fees paid (§ 106‑857(a)).
Full site plan showing building footprints, elevations, materials/colors, dimensions, setbacks, parking layout, and landscape plan (landscaping standards per § 106‑346–§ 106‑348). § 106‑857(b); § 106‑346–§ 106‑348.

Evidence that off‑street parking and loading comply with Division 3 of Article III (parking counts, layout) — reviewers will check parking against the Code and the city’s Parking standards. § 106‑104(3).
Utility and public facility plans or statements showing capacity for water, sewer, stormwater, fire access; these are part of findings for approval. § 106‑859(e) and § 106‑860(5).
For housing projects: the materials necessary to make the special housing findings (see § 106‑859(2)) — objective design standards must be met or denial is limited. § 106‑859(2).
If applicable: CEQA documents or evidence that CEQA review has been completed in advance of final approval (§ 106‑860(4)).

Risks & Ambiguities

Issue	Why it matters	What to verify
Whether the proposal is legally “development” that triggers site plan review	Triggers in § 106‑856 (e.g., 200 sq ft, second floor, 20% / 500 sq ft) determine route (ministerial vs discretionary). Mis‑classifying can delay permits.	Verify scope vs. § 106‑856 on your parcel and confirm measurement basis (net added GFA). § 106‑856
Specific plan (SP‑5) versus base zoning	SP‑5 standards are mandatory where they apply and may supersede or add to design rules; inconsistent submittals can be rejected.	Confirm whether the parcel is inside SP‑5 and follow SP‑5 required submittal list. § 106‑135, § 106‑133
“Objective design standards” vs discretionary design review	Objective standards constrain discretionary denial for housing projects (see special findings); discretionary design review can involve policy judgments.	For housing projects review § 106‑859(2); if your project meets objective standards, denial grounds are limited. § 106‑859(2)
Overlap with other permits (CUPs, variances, ADUs, building permits)	Site plan/design review is coordinated with CUPs, variances and may block issuance of building permits until resolved.	Confirm other entitlements required and sequencing: see § 106‑857(d) and zone clearance provisions § 106‑823–§ 106‑827. § 106‑857(d), § 106‑823
Historic resources	Work on historic resources may require certificates (COA/Certificate of No Effect) through the preservation procedures and is reviewed under the historic rules, not only design review.	Check the city’s historic register and historic preservation process; see the Historic Preservation page. Not all design exemptions apply to designated resources. (See historic provisions in the Code — certificate definitions).

Plain‑English summary

If you change the outside of a San Fernando building in a way that’s significant (e.g., add ≥200 sq ft on a house, add a second story, or enlarge a commercial/industrial building by ≥20% or 500 sq ft, or build in a PD/RPD/MU or SP‑5 area), you will normally need a formal site plan review and the city must make explicit findings before approving design; smaller paint/material tweaks may be handled administratively. The controlling rules and triggers are in § 106‑856 through § 106‑860 and the residential/overlay tables (e.g., § 106‑43, § 106‑165) — always verify the parcel’s zone and any specific plan overlay.

Frequently asked questions

Do I need design review (site plan review) for a 300 sq ft addition to my single‑family home in San Fernando?

Yes — a residential exterior alteration that adds 200 sq ft or more triggers a site plan review permit under § 106‑856(3); the director will review the plans for conformity to code, the general plan and any design guidelines before approval.

What are the R‑1 setback and height standards I should design to?

The residential tables in § 106‑43 (Tables 106‑43.1/106‑43.2) list standard setbacks (front ~20 ft, rear 20 ft, side 5 ft) and a maximum height of 35 ft for R‑1 homes; use these when preparing elevations and site plans. § 106‑43.

If I change my building colors and siding, can that be handled administratively?

Often yes. Exterior color or material changes that do not change the basic form or theme of the building are listed as examples of minor administrative planning review under § 106‑846(a) and can be approved by the director rather than a full site plan review, provided no other entitlements are triggered. § 106‑846.

Does the SP‑5 specific plan area impose separate design rules?

Yes. Properties inside the SP‑5 San Fernando Corridors Specific Plan must follow SP‑5’s mandatory development standards and recommended design guidelines; the specific plan controls where it addresses an issue and is applied during site plan review per § 106‑135 and § 106‑133. § 106‑133, § 106‑135.

What findings must the city make to approve a housing project?

For housing projects the review authority must find the project does not have a specific, adverse health/safety impact, is consistent with the zoning district requirements and objective design standards, and is consistent with the general plan and public facilities availability per § 106‑859(2). § 106‑859(2).

Can site plan review be appealed if the director denies it?

Yes — decisions of the director or the planning commission can be appealed under the Code’s appeal rules (appeal to the planning commission or city council) and the appeal timeframes and fees are set out in the administrative divisions (see § 106‑817 and following). § 106‑817.

Are landscaping and tree standards reviewed as part of design review?

Yes — landscape plans and plant size/species requirements are part of submittals and are reviewed; the landscape rules and preservation standards are in § 106‑346 – § 106‑348 and tree protection is in § 106‑350. § 106‑346 – § 106‑350.

If my commercial building adds 400 sq ft, do I need site plan review?

Possibly: commercial or industrial exterior alterations that result in 20% or more of existing square footage or 500 sq ft, whichever is less, are triggers per § 106‑856(4); a 400 sq ft addition may trigger review if 400 sq ft ≥ 20% of your existing area (check the percentage test). § 106‑856(4).

What about ADUs — does design review apply differently?

ADU rules are governed by state law plus the local ADU rules; the Code provides development and setback standards that apply — check the San Fernando ADUs page and the local zoning standards. If an ADU’s scope triggers the site plan thresholds (e.g., second story, size), site plan or administrative review rules will apply. Verify with the director for parcel‑specific applicability.

Where can I confirm whether my property is in SP‑5 or an overlay that changes design review?

Confirm on the official zoning map and the code’s specific plan and overlay sections: SP‑5 and other overlays are defined in § 106‑131 – § 106‑136 and the overlay rules in Division 6. If inside an overlay, the specific plan/overlay standards control. § 106‑131 – § 106‑136. ---
