Overview

The City of Larkspur centralizes exterior design oversight in Chapter 18.64 — Design Review of the municipal (Title 18) zoning code. Design review applies to most discretionary land-use permits and to building projects that affect exterior appearance; smaller, objective or ministerial projects are often exempt. See the code for the full list of triggers, exemptions and procedural steps (§ 18.64.020) .

For related topics you will see throughout this page: the City’s rules on design review are in the zoning code and implemented alongside the city’s rules on parking (/us/california/larkspur/parking), development standards (/us/california/larkspur/development-standards), overlay districts (/us/california/larkspur/overlay-districts), ADUs (/us/california/larkspur/adu), and the California Building Standards Code (/us/california/building-codes). Projects affecting historic resources also invoke historic preservation (/us/california/larkspur/historic-preservation) review (§ 18.64.020, § 18.19.040) . Sign controls, landscaping and nonconforming/variance rules interact with design review and are handled in their respective chapters (signage, landscaping and screening, nonconforming uses, variances) (/us/california/larkspur/signage) (/us/california/larkspur/landscaping-and-screening) (/us/california/larkspur/nonconforming-uses) (/us/california/larkspur/variances-and-exceptions).

How Larkspur’s Design Review works (core rules)

Trigger: "Any site or building development or modification requiring a discretionary land use permit or a building permit" is subject to design review unless specifically exempt (§ 18.64.020(A)) .
Exemptions: common exemptions include new single‑story single‑family dwellings and single‑story additions that comply with all zoning standards and do not exceed 20 ft in height, small accessory structures ≤ 400 sq ft, roof solar panels that do not extend more than 3 ft above the roofline, ministerial projects in areas covered by prior approved design guidelines, and maintenance/repair under Chapter 18.68 (§ 18.64.020(B)) .
Decision bodies: depending on project scale and type, review may be by the Zoning Administrator, the Planning Commission, or the Community Development Director (Zoning Administrator list at § 18.64.025; Planning Commission list at § 18.64.030) .
Application materials: plans required include a site plan, grading, sections, conceptual elevations, preliminary floor plans and a parking plan showing compliance with disabled and loading standards (detailed in § 18.64.040) .
Findings / approval criteria: approvals require findings on neighborhood compatibility, bulk, public health and safety, consistency with other plans, and green‑building/energy conservation measures (standards summarized in § 18.64.055) .
Conditions, bonds, compliance and inspections: the Commission/Zoning Administrator can approve with conditions, require bonds, and the Chief Building Official enforces on‑site compliance with approved design review conditions (§ 18.64.060, § 18.64.070, § 18.64.080) .
Expiration: design review approvals expire after two (2) years; a one‑year extension may be granted by the Community Development Director; additional extensions require Commission action (§ 18.64.090) .
Fees: applications and any extension/appeal fees are set by City Council resolution; submit on the City form with the required fee (§ 18.64.100) .

District-by-district breakdown (where design review applies)

Below are the zoning districts that explicitly reference design review in their district chapters. For each district I list the district identifier in bold, the purpose, typical permitted uses, key development/dimensional rules that the district spells out in the ordinance text, and where design review is referenced.

Note: the municipal code is organized with each district in its own chapter (for example Chapter 18.20 for the First Residential or R-1 district). All district citations below point to the zoning text that explicitly requires design review for exterior work.

R-1 — First Residential District

Purpose: to provide low‑density single‑family neighborhoods and protect existing single‑family character (§ 18.20.005) .
Typical permitted uses: one‑family dwellings, accessory structures/uses, parks, group homes, transitional/supportive housing, residential care, ADUs/JADUs per Chapter 18.23 (§ 18.20.020) .
Key dimensional rules: the chapter establishes yard and setback subsections (see Chapter 18.20 for the full numeric yard and height rules) — where not numerically repeated here, refer to the district chapter for exact figures (§ 18.20.060 et seq.) .
Design review: all exterior additions and new structures are subject to Chapter 18.64 unless the project meets the Chapter 18.64 exemptions; exempt single‑family projects that are still objective‑standards‑only must comply with Title 20 objective standards (§ 18.20.085) .

R-2 — Second Residential District

Purpose: medium‑density residential neighborhoods built to the R-1 character and General Plan (§ 18.28.005) .
Typical permitted uses: one‑family and two‑family dwellings, accessory buildings/home occupations, parks, group homes, transitional/supportive housing, family day care, ADUs (§ 18.28.020) .
Key standards: Chapter 18.28 sets lot area, height, coverage, yards and FAR; ADUs are allowed subject to Chapter 18.23 (§ 18.28.020) .
Design review: the district includes a specific design review clause that points to Chapter 18.64 and Heritage Preservation review where applicable (§ 18.28.085) .

R-3 — Third / Multiple‑Family District

Purpose & uses: intended for multi‑family residential development; the chapter includes the same cross‑reference to design review for exterior work (§ 18.48.085) .
Key standards: yard rules, rear/side yard special conditions and massing requirements are in the R‑3 chapter; multi‑family projects and additions are typically routed to Planning Commission review under the design review rules (§ 18.48.060 – .085) .

SD — Storefront Downtown / Downtown Specific Plan

Purpose: downtown storefront character; special frontages along Magnolia Avenue and Ward Street are regulated (§ 18.41.010 et seq.) .
Typical permitted uses: retail, service, mixed‑use, and residential where allowed by the Downtown Specific Plan (see Chapter 18.41) (§ 18.41.020 - .030) .
Key dimensional rules: front yards — none required, with mandatory zero front setback on Magnolia Avenue and Ward Street in specified blocks; side and rear yard rules are tailored to downtown function (§ 18.41.090) .
Design review: all exterior work in SD is subject to Chapter 18.64, and historic resources in the SD area also trigger Heritage Preservation Board review (§ 18.41.120) .

C-1 — Neighborhood Commercial District

Purpose & uses: neighborhood commercial services and retail serving local needs (§ 18.44 chapter) .
Key dimensional standards: front yard minimum of 10 ft (no parking allowed in that yard), side/rear yard special conditions where adjacent to residential or A‑P, landscaping buffer requirements in some edge conditions (§ 18.44.060) .
Design review: exterior work is subject to Chapter 18.64; when adjoining residential or A‑P districts, the Planning Commission may impose landscape/fence buffering as part of design review (§ 18.44.085) .

A‑P — Administrative/Professional District

Purpose & uses: office and professional uses; emergency shelters are explicitly permitted here under standards (§ 18.40 chapter) .
Key dimensional rules: the chapter contains specific yard and setback rules and cross‑references circulation and parking requirements (§ 18.40.060 – .100) .
Design review: all exterior modifications are subject to Chapter 18.64; heritage properties also follow Chapter 18.19 (§ 18.40.085) .

L-1 — Light Industrial District

Purpose & uses: light industrial/industrial service uses; design review is required for exterior changes (§ 18.52.085) .
Key standards: the chapter sets out yard coverage, circulation, and parking requirements; accessory structures exempt rules apply as noted in the district (§ 18.52.060 – .110) .

H — Combining Heritage Preservation District (overlay)

Purpose & process: properties in the H overlay (and any building on the City Historic Resources Inventory) get additional review and recommendation by the Heritage Preservation Board; major exterior changes typically require Planning Commission action after the Board’s recommendation (§ 18.19.040, § 18.64.020) .
Practical effect: projects that would otherwise be Zoning Administrator‑level may be escalated for heritage review; minor historic changes are routed to the Zoning Administrator with possible consultant input (§ 18.64.025, § 18.19.040) .

Risks & Ambiguities

Issue	Why it matters	What to verify
ADU design review trigger	ADUs are generally allowed, but some ADUs are exempt while others are routed to design review under Chapter 18.23	Confirm whether your proposed ADU triggers design review under § 18.64.020 and Chapter 18.23 (§ 18.23, § 18.64.020)
Heritage overlay escalation	Historic resources can turn otherwise ministerial work into discretionary review and require consultant reports	Check whether the parcel is listed or eligible on the City Historic Resources Inventory and the Heritage Board rules (§ 18.19.040, § 18.64.020)
Exact numeric setbacks/FAR per parcel	District chapters give different yard and FAR rules; some numeric standards aren’t quoted here	For parcel‑specific setbacks/FAR, consult the applicable district chapter (e.g., 18.20, 18.28, 18.41, 18.44) and verify with the City — parcel determination is necessary. Verify with the jurisdiction.
When Planning Commission vs Zoning Administrator decides	The thresholds in § 18.64.025 and § 18.64.030 define who hears the case; Community Development Director may reassign	Confirm which body will hear your project early in the pre‑application meeting; the Community Development Director can direct hearings (§ 18.64.025, § 18.64.030)
Objective‑standards exemption (Title 20)	Some projects that meet Title 20 objective standards are exempt from design review, which changes processing and appeal rights	If pursuing the objective standards route, ensure full compliance with Title 20 to avoid discretionary review (§ 18.20.085, § 18.101.060)

Plain‑English summary

If your project changes how a building looks from the outside or needs a discretionary permit, expect Larkspur’s design review process (Chapter 18.64) — you’ll file plans, attend a noticed hearing (Zoning Administrator or Planning Commission), and the reviewers will check compatibility, bulk, materials, landscaping, parking and neighborhood impacts before they approve, conditionally approve, or deny it; heritage properties and some housing projects follow special rules (§ 18.64.020, § 18.64.040, § 18.64.055) .

Information Gaps

Exact numeric setback figures for every district are not exhaustively reproduced here. Where a district chapter lists numbers (e.g., some C‑ and SD‑district rules), I cited the chapter reference; for parcel‑level setbacks or FAR, verify with the district chapter or the City. Not found in retrieved materials: a single consolidated table of all district numeric dimensional standards across Title 18 (consult Chapters 18.20, 18.28, 18.41, 18.44, 18.48, 18.52, etc.) .
Fees schedule amounts are set by City Council resolution and are not included in the retrieved Title 18 files; check the City’s current fee resolution or contact the Planning Department. Not found in retrieved materials: the numeric fee amounts (§ 18.64.100) .
Specific procedural checklists or submittal templates used by Planning staff (beyond the plan list in § 18.64.040) are not in Title 18. Contact Planning staff for current PDF submittal checklists. Not found in retrieved materials: the City’s submittal packet forms.

Frequently asked questions

Do I always need design review in Larkspur?

Not always. Design review is required for most discretionary land‑use permits and building permits that change exterior appearance, but Title 18.64 lists exemptions (for example, new single‑story single‑family homes meeting district standards, small accessory structures ≤ 400 sq ft, and low‑profile solar panels) — see § 18.64.020(B) for the exemption list and verify for your project.

What kinds of projects go to the Planning Commission versus the Zoning Administrator?

Larger projects and specific types (e.g., new two‑story single‑family homes over 20 ft, multifamily buildings, commercial buildings, additions over certain sizes) are listed for Planning Commission review in § 18.64.030; more limited changes (small second‑story additions ≤ 300 sq ft, accessory buildings > 400 sq ft but not requiring other permits, minor storefront changes) are listed for Zoning Administrator review in § 18.64.025. Confirm the exact threshold that applies to your project early in the pre‑application stage.

What must I submit with my design review application?

The ordinance requires a set of materials including a topographic/site plan, grading plan, sections, conceptual elevations showing adjacent building portions, preliminary floor plans, and a parking plan demonstrating compliance with disabled and loading standards — see § 18.64.040 for the full submission list.

Are historic buildings treated differently?

Yes. Properties in the Combining Heritage Preservation District (zoned H) or on the City’s Historic Resources Inventory are subject to Heritage Preservation Board review and recommendation in addition to design review; major exterior changes may require Commission action after the Board’s review (§ 18.19.040, § 18.64.020)

Do accessory dwelling units (ADUs) need design review?

Most ADUs are permitted and exempt from discretionary review, but the code specifically notes that attached/detached ADUs are exempt unless design review is required under Chapter 18.23; check § 18.23 and § 18.64.020 to determine whether your ADU proposal will be subject to design review. Verify specifics with the Planning Department for site‑specific triggers.

How long does a design review approval last and can I extend it?

A design review approval expires after two (2) years. Before expiration you may apply to the Community Development Director for a one‑year extension; any further extension requires Planning Commission approval (§ 18.64.090)

What happens if I build something that doesn’t match the approved design review?

Noncompliance is grounds for the City to stop work and to withhold or deny occupancy until the approved design is met; in some cases the City allows a cash bond in lieu of immediate completion if justified (§ 18.64.080)

Can I avoid design review by complying with objective standards?

Yes — certain housing projects that comply fully with the City’s objective standards (Title 20) are exempt from discretionary design review; see § 18.20.085 and the Housing Priority rules regarding objective‑standard pathways (§ 18.101.060). Confirm eligibility before filing.

How are neighbors notified of a design review hearing?

Notice is provided by mail to owners within 300 ft of the site, by posting on the property, and on three public noticing boards in the City prior to the hearing (§ 18.64.035)

Who enforces compliance with approved design review conditions?

The Chief Building Official (or designee) checks building permit drawings and inspects for compliance with design review approvals; deviations are reported to the Community Development Director (§ 18.64.060(D))
