Sausalito — Historic Preservation

Historic Preservation under the Sausalito local zoning and planning code, with the controlling citations.

Last reviewed: July 2, 2026

Overview

Sausalito’s historic preservation rules live in Title 10 (Zoning) and are implemented through a local historic register, a citywide -H historic overlay, a Certificate of Appropriateness review process, and the Historic Preservation Commission. The rules create a designation/appeals path, 180‑day interim protection on proposed listings, demolition delay and alternatives, and incentives (including limited building‑code exceptions) tied to local or listed historic resources. See how this interacts with the city’s Zoning, Development Standards, and design processes below. § 10.28.040, § 10.46.020–070 .

How Sausalito’s historic rules work (high level)

Local mechanisms: a Local Historic Register and a maintained local Historic Resources Inventory that the Historic Preservation Commission keeps up to date; properties may be nominated by owners, the public, the HPC or Council. § 10.46.040–050 .
Overlay approach: the -H (historic) overlay can be applied over any base zoning district; it adds preservation review and may identify contributing and non‑contributing resources. § 10.28.040 .
Review: exterior work, new construction, signs and landscaping on register properties or inside an -H require a Certificate of Appropriateness (advisory from the Historic Preservation Commission) before other discretionary approvals; minor categories may be delegated administratively. § 10.46.060 .
Interim protection & demolition: initiation of designation triggers a 180‑day pause on exterior permits (limited maintenance and safety exceptions). Demolition of historic resources requires specific findings and, if withheld, may generate a 180‑day delay to seek alternatives. § 10.28.040(G)(5), § 10.46.070(H) .
Incentives: fee waivers, and limited building‑code exceptions when conforming to the State Historic Building Code are explicitly allowed. § 10.46.070 .

Practical note: design review and historic review are closely connected; read the design review thresholds in the Design Review chapter when planning a project. The Design Review chapter is in Design Review and the City’s sign rules tailored for historic properties are in Signage. § 10.54.010, § 10.42.070 .

District‑by‑district breakdown

Sausalito’s preservation rules apply citywide but are implemented as an overlay (-H) on top of the base zoning districts. Below is a Sausalito‑specific, district‑by‑district orientation: purpose, typical uses, key dimensional standards that matter to preservation review, and where that district commonly appears in the city. (Always confirm parcel status with the Community Development Department — Verify with the jurisdiction.)

Notes on sources: base district uses and dimensional standards are summarized from the Zoning District tables and the General Development Regulations; preservation overlay rules are in the historic and preservation chapters. § 10.20–10.28, § 10.40, § 10.46 .

Residential districts

R‑1 (Single‑Family Residential)
- Purpose: preserve single‑family neighborhoods. Typical permitted uses: single‑family dwellings, accessory structures, limited residential accessory uses. § 10.22.030–040 .
- Key standards relevant to preservation: maximum FAR ~ .45, maximum building coverage ~ 35%, rear setback 15 ft, maximum height 32 ft (see Table 10.22‑2 and Chapter 10.40). § 10.22.040, § 10.40.050–060 .
- Where it applies: most single‑family neighborhoods; if combined with -H, additions or ADUs in an -H must meet historic compatibility findings and ADU siting rules (see ADU protections). § 10.28.040, § 10.44.080 .
R‑2, R‑3, PR, H, A (Other residential categories)
- Purpose & uses: range from denser multi‑family (R‑3, PR) to special zones (H, A) with permitted residential and accessory uses. Tables set minimum parcel sizes, FAR, coverage and setbacks that affect how repairs, additions, or new infill fit the historic context. § 10.22.030–040, Table 10.22‑2. .
- Preservation takeaway: the -H overlay does not change base zoning numeric standards unless a preservation agreement or another overlay modifies them, but it imposes compatibility and Certificate of Appropriateness review for exterior changes. § 10.28.040(D), § 10.46.060(3) .

Commercial districts

CC, CR, CN, SC, CW, W, W‑M (Commercial & waterfront districts)
- Purpose: downtown/visitor serving uses, waterfront marine/service uses, and mixed visitor/resident commerce. Typical permitted uses: retail, restaurants, visitor‑serving stores, wholesale fish sales, professional services (see Table 10.24‑1). § 10.24.030 .
- Key standards: building coverage and FAR and specific sign controls influence historic storefront treatment. Signs on historic properties require a Certificate of Appropriateness under the historic sign rules. § 10.42.070, § 10.46.060(4) .
- Where applied: Bridgeway, downtown corridor and waterfront parcels; when these commercial parcels are inside an -H, the City’s Historic Design Guidelines and sign rules are mandatory for compatibility. § 10.28.040(E) .

Industrial / Marinship district

Marinship / Industrial (Chapter 10.26)
- Purpose: maritime/industrial uses with site‑specific development standards. If a maritime structure or yard is historically significant it can be placed on the local register or included in an -H; in that case preservation review, adaptive reuse incentives, and demolition findings apply. § 10.26, § 10.46.050–070 Not found in retrieved materials for full Marinship text; historic rules apply generally per the preservation chapter. .

Overlay districts relevant to preservation

-H (Historic Overlay District)
- Purpose: to protect groups of structures that together have historic character; shown on the zoning map as a suffix (for example, CN‑H or R‑1‑H). Establishment criteria include architectural, cultural, historic event, or visual prominence. § 10.28.040(F–G) .
- How it affects uses/standards: base district numeric standards remain in force for land use and development unless a preservation agreement or another overlay modifies them; however, exterior work inside an -H must be compatible and typically requires a Certificate of Appropriateness. § 10.28.040(D), § 10.46.060(3) .
- Where applied: specific areas designated by Council; each district gets an "-H" number (H‑xx) and a map record. Check the zoning map / Table 10.28‑2 for site listings where overlays like H‑29, H‑49, H‑70 apply. § 10.28.090 .

Risks & Ambiguities

Issue	Why it matters	What to verify
Is the parcel already listed or in the Inventory?	Existing listing triggers mandatory Certificate of Appropriateness and demolition findings.	Confirm status with Community Development and the Local Historic Resources Inventory. § 10.46.040–050
Is the parcel inside an -H overlay?	Overlay subjects all exterior changes to compatibility findings even if base zoning numeric standards are unchanged.	Check official zoning map and any -H number (H‑xx). § 10.28.040(B–D)
Subjectivity of “compatibility”	Certificate findings reference compatibility with district character and the Secretary of the Interior’s Standards — interpretation can vary.	Expect HPC and Planning Commission discretion; request pre‑application review and consult adopted Historic Design Guidelines. § 10.46.060(F)(1–3)
CEQA implications	Listing and some project approvals require environmental review which can add time/cost.	Confirm if CEQA/initial study or EIR is required and budget for environmental review. § 10.46.050(G)(2)
Demolition alternatives & delays	HPC can withhold demolition approval for 180 days to explore alternatives — may delay projects.	Plan for potential 180‑day hold and document reuse/financial options. § 10.46.070(H)
Overlap with other overlays (e.g., Housing Opportunity)	Multiple overlays (H‑29, H‑49, etc.) can modify allowable uses, density or design rules.	Verify all overlays on the parcel and which overlay standard is controlling. § 10.28.090

Plain‑English summary

If your Sausalito property is on the Local Historic Register or inside a -H historic overlay, expect mandatory historic review for exterior changes: you'll normally need a Certificate of Appropriateness from the Historic Preservation Commission (advisory) and related design review before other discretionary approvals; demolition faces special findings and possible 180‑day hold; incentives and some building‑code exceptions exist for rehabilitation if you follow the Secretary of the Interior’s Standards. § 10.28.040, § 10.46.060–070 .

Frequently asked questions

What does the -H historic overlay mean for my property in Sausalito?

If your parcel is within a -H overlay, exterior work, new construction, signs and landscaping are subject to compatibility review and generally require a Certificate of Appropriateness; base zoning numeric standards still apply unless modified by another overlay or a preservation agreement. § 10.28.040(D–E)

How is a property added to Sausalito’s local historic register?

A property may be initiated for listing by the City Council, the Historic Preservation Commission, the property owner or members of the public; the HPC reviews at a public hearing, makes a recommendation to City Council, and Council acts; recordation follows upon approval. § 10.46.050(A–G)

Do I need a Certificate of Appropriateness before I replace windows or change siding?

Yes — exterior alterations to properties listed on the local register or within an -H are reviewed by the Historic Preservation Commission via a Certificate of Appropriateness unless the work is explicitly delegated as an administrative minor alteration. The review uses the Secretary of the Interior’s Standards. § 10.46.060(F)(1)

If my building is proposed for designation, can I still get a permit?

After initiation of designation, exterior alteration permits are generally delayed for 180 days, though ordinary maintenance and emergency work are allowed; pending permits may be processed but not finalized until the designation decision or after 180 days. § 10.28.040(G)(5)

What happens if I want to demolish a building that’s on the local register or in an -H?

Demolition requires additional findings: CEQA compliance, alternatives considered (including adaptive reuse), financial alternatives reviewed, and for accessory structures extra findings. The HPC can withhold demolition and impose a 180‑day delay to pursue alternatives. § 10.46.060(F)(6), § 10.46.070(H)

Can I get building‑code relief for rehabilitating a historic building?

Yes — the ordinance explicitly allows building‑code deviations when the work conforms to the State Historic Building Code; preservation rehabilitation projects may also receive fee waivers for certain certificates of appropriateness. § 10.46.070(B–A)

Are signs treated differently in historic districts?

Yes — signs on register properties or within an -H must obtain a Certificate of Appropriateness, follow the Historic Design Guidelines, and many sign types (neon, roof, freestanding, electronic) are strongly discouraged. § 10.42.070(C–F)

Do ADU rules change if I’m in a historic district?

Sausalito requires ADUs in a historic district to be located behind the rear‑most exterior wall of the primary dwelling and to comply with the Secretary of the Interior’s Standards for work affecting historic resources where applicable. § 10.44.080(G)(10)

Who is the decision maker for historic reviews in Sausalito?

The Historic Preservation Commission conducts the Certificate of Appropriateness review (advisory) and recommends to the Planning Commission or City Council as the situation requires; the HPC is established per City code. § 10.46.060, § 10.80.060

If the HPC issues an advisory recommendation, can the Planning Commission change it?

The HPC’s advisory Certificate of Appropriateness is forwarded to the decision‑making body; the Planning Commission may not directly modify the advisory resolution but can refer it back to the HPC for reconsideration. § 10.46.060(D–E)
