Overview

This page explains how design review and site plan review work under Lomita's zoning ordinance (Title 11 of the Lomita Municipal Code). It summarizes who reviews designs, the required findings, what types of projects commonly trigger review, and the decision standards you must meet. For related topics see the city's pages on development standards, parking, overlay districts, ADUs, and the California Building Standards Code.

What the code calls "design review" (site plan review)

The Lomita code implements design/architectural review primarily through Site plan review. The controlling rules and required findings for that review are codified at § 11-1.70.07.
The director of community development (staff) is authorized to approve site plan reviews when the proposal is fully consistent with the zoning code; discretionary or modified decisions may go to the Planning Commission, and Planning Commission decisions may be appealed to City Council. See § 11-1.70.07 and § 11-1.70.16.
The Planning Commission (or City Council on appeal) may approve modifications to standards only when accompanied by a satisfactory site plan review and when physical conditions create an unnecessary hardship (see § 11-1.70.08).

Primary site-plan review findings the decision-maker must make (language condensed from the code):

The site plan complies with all applicable provisions of Title 11 (§ 11-1.70.07(B)(1)).
The site is suitable, the layout avoids traffic congestion and public-safety problems, and is consistent with the General Plan (§ 11-1.70.07(B)(2)).
The development design is suitable and functional; the code explicitly says this is not a mandate for any particular architectural style (§ 11-1.70.07(B)(3)).

If a project meets the code literally, the director signs the plan and the decision is final (no appeal), except where the application is identified as discretionary elsewhere in Title 11 (§ 11-1.70.07(C)).

District-by-district breakdown (how Design/Site Plan Review interacts with districts)

Below are the Lomita districts and how design/site-plan review interacts with them. Bolded district names and key numeric standards are taken from the ordinance table of standards and the Specific Plan text; each entry cites the controlling §.

Note on terminology: the Lomita ordinance identifies zones such as A-1, R-1, R-2, R-3 (residential zones) and commercial district codes used in other tables such as DC, NC, CC, RC. Use and site-plan-review triggers are shown in the code's use and standards tables.

Residential zones — A-1, R-1, R-2, R-3

Purpose: standard agricultural and residential zones with progressively higher density allowances. Site plan review, modifications, and planned-residential processes apply when development departs from objective standards or when the ordinance flags a use with an "S" (site plan review) requirement. See § 11-1.30.02 (Table 11-1.30.B) and Notes.

Typical permitted uses: single‑family residence (P), two-unit developments where allowed, accessory structures, planned residential developments (PRD). See Table 11-1.30.B for permitted use notes.

Key dimensional standards (Table 11-1.30.B / § 11-1.30.02):

Maximum density: A-1: 10.89 du/ac, R-1: 10.89 du/ac, R-2: 19.79 du/ac, R-3: 43.6 du/ac.
Maximum principal building height: A-1 / R-1 / R-2: 27 ft, R-3: 35 ft.
Typical setbacks: Front: 20 ft, Side: 5 ft, Rear: 20 ft (notes and exceptions apply) — see § 11-1.30.02.

Where site-plan review applies: the ordinance notes site plan review is required for new buildings or additions that increase parking needs and for other uses marked "S" in the use tables; some additions (e.g., second‑story additions with close setbacks) require site plan approval specifically (§ 11-1.30.03(B) and Table Notes).

Planned Residential Development — PRD

Purpose and triggers: PRDs allow clustering and flexibility subject to an administrative site plan review under Article 70; the administrative site plan review is binding and regulates construction/location/maintenance once approved (§ 11-1.30.17).

Required materials: PRD applications require a general development plan with dimensions, uses, elevations, parking calculations, landscaping, grading plan and other details (see § 11-1.30.17(F)).

24000 Crenshaw Boulevard Specific Plan

This site-specific plan covering a defined parcel is its own set of development standards (density cap, setbacks, heights). For example: maximum height 64 ft in certain faces, front setback 16 ft, side 10 ft, rear 34 ft — see § 11-1.27.04 and § 11-1.27.05. Site plan and design approvals follow the Specific Plan requirements plus Article 70 procedures.

Commercial/Other districts — DC, NC, CC, RC (and special-purpose zones)

Purpose and permitted uses: These commercial district codes appear in tables that list permitted uses and show when a Site plan review (marked "S") or Conditional Use Permit ("C") is required. The lot consolidation/incentive table and other district-specific tables list these designations; consult Table 11-1.53.A and use tables for exact use-by-district rules (§ 11-1.53.09 and the use tables).

Key point for applicants: commercially‑zoned projects commonly trigger site-plan review (for storefront design, parking layout, lighting, waste enclosures, signage and landscape), and the review authority can attach conditions to secure compliance with development standards (§ 11-1.70.14).

How site-plan/design review works in practice

Pre-application: the director may require specific materials (plans, landscape and irrigation plans, elevations, visual simulations, parking calculations and any studies needed) and may waive inapplicable requirements (§ 11-1.70.07 & application requirements notes).
Approval authority: Staff (Director of Community Development) signs off on ministerial-consistent plans; discretionary matters or modifications go to the Planning Commission, with appeal to City Council (§ 11-1.70.07(C); § 11-1.70.16).
Conditions and denial: conditions may be imposed to bring design into conformity; where the design cannot be conditioned to comply, the project is denied (§ 11-1.70.14).
Modifications: the Planning Commission (or City Council on appeal) can approve modifications to setbacks/standards only with findings of hardship and satisfactory site-plan review (§ 11-1.70.08).

Quick decision-relevant table

Topic	Key rule / standard	Code Reference
When is a site plan review required?	When the code or use table marks a use with "S", for new buildings or additions that increase required parking, and for PRDs and other proposals noted in Title 11.	§ 11-1.30.02 (Table 11-1.30.B)
Primary site-plan review findings	Plan must comply with Title 11; site must be suitable and avoid traffic/safety problems; design must be suitable and functional.	§ 11-1.70.07
Who can approve?	Director of Community Development for ministerial-consistent plans; Planning Commission for discretionary matters; City Council on appeal or coordinated review for multi-entitlement projects.	§ 11-1.70.07(C); § 11-1.70.16
Modifications to standards	Allowed only with findings of hardship and satisfactory site-plan review; the Planning Commission (or Council on appeal) grants modifications.	§ 11-1.70.08
PRD submittal essentials	Development plan must include site dimensions, uses, elevations, parking calculations, landscaping, grading plan, easements, and renderings.	§ 11-1.30.17(F)

Checklist (what an applicant must satisfy for a typical site-plan/design review)

Demonstrate compliance with underlying zone standards (setbacks, heights, density) per § 11-1.30.02 (residential) or applicable district tables.
Provide full site plan showing building footprint, parking count and layout, drive aisles, access, and circulation (parking triggers site-plan review).
Submit elevations/architectural renderings and visual simulations showing materials, colors and finishes per PRD/development-plan requirements when applicable (§ 11-1.30.17(F)).
Landscape and irrigation plan where required; screening for utilities, trash/recycling enclosures and mechanical equipment per relevant articles.
If requesting modifications (e.g., reduced setback), include hardship evidence tied to topography or parcel constraints per § 11-1.70.08.
Be prepared for conditions of approval; when design cannot be conditioned to comply, expect denial (§ 11-1.70.14).

Risks & Ambiguities

Issue	Why it matters	What to verify
Whether a proposed change is discretionary or ministerial	Ministerial approvals by the Director cannot be appealed; discretionary items go to Planning Commission and have a public hearing — timing and requirements differ.	Verify whether the specific entitlement is listed as discretionary in Title 11 or shown as "S" or "C" in the use table; check § 11-1.70.07(C) and the use tables.
Exact scope of submittal materials for ordinary commercial/site projects	The code lists many potential materials (studies, photometric plans, master sign plan) but often delegates specifics to the Director.	Confirm required checklist with Community Development Director at intake; the Director may waive or require items (§ 11-1.70.07).
Whether a proposed ADU needs design/site-plan review versus only a building permit	State ADU law interacts with local code; Title 11 sometimes treats accessory structures and ADUs differently.	Verify ADU treatment: the ordinance notes ADUs/JADUs may be subject to building permit or ADU-specific rules (Table Notes) and consult the city's ADU page and California ADU law. Not found in retrieved materials: precise threshold language about automatic ministerial approval for ADUs.
Interpretation of "suitable and functional" design finding	Subjective phrase; risk of divergent staff/commission interpretations about aesthetics or neighborhood compatibility.	Expect objective conditions (setbacks, screening, parking) to control; for ambiguous issues, document how proposal meets traffic, screening, and neighborhood compatibility requirements (§ 11-1.70.07(B)).
Whether specific sign/landscaping rules will trigger additional review	Sign and landscape details often produce separate permit triggers (e.g., master sign plan).	Confirm with the sign and landscaping chapters and the Community Development Director; see city sign rules and § 11-1.30.17(F) listing landscaping requirements for PRDs.

Plain-English Summary

In Lomita, "design review" is handled through the code's site plan review process: staff approves straightforward plans that strictly meet the rules, while projects that need exceptions, reductions, or that are discretionary go to the Planning Commission. The reviewer must find the plan complies with the zoning rules, is safe for circulation and neighbors, and is "suitable and functional" — and the city can impose conditions or deny projects that can't be conditioned into compliance (§ 11-1.70.07, § 11-1.70.14).

Frequently asked questions

Do I need design review (site plan review) for a second‑story addition to my R-1 house in Lomita?

If the second-floor addition reduces a required side yard to less than 5 ft or otherwise conflicts with development standards, site plan approval is required; the ordinance specifically requires site plan approval for second‑story additions with less than a 5‑foot setback and ties such review to § 11-1.30.03(B) and the general site‑plan review rules in § 11-1.70.07.

What are the typical front/side/rear setbacks I must meet in Lomita residential zones?

The general residential table sets typical setbacks at Front: 20 ft, Side: 5 ft, Rear: 20 ft (with exceptions and notes); see Table 11-1.30.B and § 11-1.30.02 for full details and exceptions.

Who approves site-plan/design review decisions in Lomita?

The Director of Community Development can approve site-plan reviews that are fully consistent with Title 11; discretionary decisions and modifications are heard by the Planning Commission, with appeals to the City Council — see § 11-1.70.07(C) and § 11-1.70.16.

What findings will the Planning Commission make to approve a design modification?

To approve a modification (e.g., reduced setback), the Commission must find the modification is requested with a satisfactory site plan review and that physical conditions create unnecessary hardship making strict compliance impractical — see § 11-1.70.08.

Does Lomita require visual simulations, colors and materials for design review?

For larger or plan-driven reviews (such as PRDs or wireless facility permits) the code explicitly requires elevations and visual simulations; PRD submittals must include elevations/architectural renderings and visual simulations may be required for certain facilities — see § 11-1.30.17(F) and the wireless facilities article.

If my project meets every numeric standard in the zoning table, can the city still deny it for design reasons?

If a proposal truly complies with all applicable provisions of Title 11, the Director signs the site plan and approval is final; however, for discretionary entitlements the review authority may impose design or operational conditions to ensure findings are met, and may deny projects that cannot be conditioned into compliance (§ 11-1.70.07(C); § 11-1.70.14).

Where do I check whether my commercial use triggers site plan review?

Consult the use tables and the notes in Title 11: uses marked "S" require site plan review (Table 11-1.30.B notes and use tables); also any new building or addition increasing parking normally triggers site-plan review (§ 11-1.30.02 and adjacent notes).

Can the Director waive submittal requirements for site-plan review?

Yes — the Director may waive application requirements if they are not applicable to the specific application; see the application requirements language in § 11-1.70.07.

Are ADUs treated differently for design review in Lomita?

The ordinance's tables note ADUs/JADUs may be subject to a building permit or ADU-specific process; the exact threshold for when an ADU triggers full site-plan review is not fully specified in the retrieved materials — verify with the Community Development Director and the city's ADU guidance. Not found in retrieved materials: explicit ADU ministerial/site‑plan thresholds.
