Oakland — Historic Preservation

Last reviewed: July 2, 2026

Overview

This page summarizes how the Oakland Planning Code (Title 17) treats historic preservation, including landmark designation, preservation combining zones, design review triggers and demolition controls. It is limited to what the local zoning/planning ordinance says (Title 17) and points to the specific findings, review routes, and standards an applicant and property owner will face. For related permitting topics see Oakland’s pages on zoning, design review, development standards, overlay districts, parking, ADUs and the California Building Standards Code.

How Title 17 organizes preservation controls (quick map)

• Preservation rules live inside Title 17 (the Oakland Planning Code), primarily in Chapter 17.136 (Design Review Procedure) and the S-20 Historic Preservation Combining Zone (Chapter 17.100B) plus various cross-references to landmark rules and other zone chapters. See the design-review purpose and application rules in § 17.136.010 and following.

District-by-district breakdown

S-20 — S-20 Historic Preservation District Combining Zone

• Purpose: Preserve and enhance areas that collectively have historic value; intended for larger historic districts and to provide a streamlined but protective review process. § 17.100B.010.
• Typical permitted uses: Uses are those of the underlying base zone; the S-20 is a combining zone that supplements the underlying zone (it “may be combined with any other zone”). § 17.100B.020.
• Key development controls and review triggers:
  • Projects that change exterior appearance generally require Regular design review under Chapter 17.136. § 17.100B.030(A).
  • Proposals must meet S-20 design criteria (compatibility, not impairing district value) and follow the City’s Design Guidelines for Landmarks and Preservation Districts; Secretary of the Interior’s Standards apply where federal standards are relevant. § 17.100B.050(A)–(C).
  • Owners must keep exterior portions in good repair. § 17.100B.080.
• Where it applies: As a combining zone it is mapped over neighborhoods determined to be historic districts (check the zoning map; APIs and character-defining features are noted there). § 17.100B.010 and related provisions referencing maps.

S-7 — S-7 Preservation Combining Zone

• Purpose: Intended to protect individual properties or smaller groupings that meet landmark-level criteria; S-7 is referenced as the more protective counterpart to S-20. See multiple design-review cross-references to the S-7 Zone in Title 17. (Referenced throughout Chapters 17.136 and 17.135).
• Typical permitted uses and standards: Uses are those of the underlying zone; the S-7 imposes stricter design review controls (including referral to the Landmarks Preservation Advisory Board for some S-7 projects). See § 17.136.060 for referral rules.
• Where it applies: Mapped over properties individually eligible for landmark designation. (Detailed mapping not in the retrieved snippets; verify with the City’s zoning map.) Not all S-7 text was included in the retrieved materials — verify with the jurisdiction.

Designated Landmark Sites (Landmarks / Landmark Sites)

• Designation: City Council may designate any facility or group as a landmark; the designating ordinance must describe features that must be preserved and the landmark site boundaries. § 17.136.070(A).
• Review and limitations:
  • Exterior alterations and many new structures on a designated landmark site require Design Review and must meet additional landmark-specific criteria. § 17.136.070(B)–(C).
  • Owners of designated landmarks have a duty to keep in good repair exterior portions (and interior portions when the designating ordinance imposes interior controls). § 17.136.070(D).

Areas of Primary Importance (API) and Areas of Secondary Importance (ASI)

• APIs and ASIs are district-level designations used by the Oakland Cultural Heritage Survey to indicate varying levels of district contribution.
  • Projects in an API require compatibility with character-defining elements and may have additional findings; APIs and any character-defining height levels are shown on the zoning maps. (See criteria for API review in Chapter 17.136 and design findings). (see §§ 17.136. and 17.100B.050 excerpts)*.
  • Structures contributing to an ASI or rated “C” by the Survey have specific demolition/replacement findings. § 17.136.075(D) and related subsections.

OS Zone referrals to Landmarks Preservation Advisory Board

• Projects in the OS (Open Space) Zone that require conditional use permits are referred to the Landmarks Preservation Advisory Board if located within S-7 or potentially impacting listed sites or formal Oakland landmarks. § 17.135.040.

Practical guidance (what the ordinance practically means)

• If your property is in a mapped S-20 or S-7 area, or is a designated landmark, plan on Regular design review: submit full elevations, materials, and context drawings and expect review against the City’s Design Guidelines and, often, the Secretary of the Interior’s Standards. See submission requirements for design review applications in § 17.136.020 and chapter-level application lists (e.g., campus-zone application checklist).
• Small repairs that visually match the historic fabric are often exempt, but the exemption requires that the work “will not have a significant effect on the structure's character-defining elements.” Do not assume an exemption—confirm with staff. § 17.136.025.
• Demolition is the hardest outcome to get approved for historic resources. For DHP/PDHP/“A” or “B”-rated properties, the applicant must demonstrate infeasibility or that a replacement is equal or superior in design quality; demolition may be delayed for preservation options. § 17.136.075.
• Many preservation controls are overlays or combining zones; the underlying zone still governs permitted uses and dimensional standards (setbacks, FAR, etc.). Check the underlying zone regulations and the overlay rules together. See the Oakland zoning and development standards pages for base standards. (Verify parcel-specific base zone and overlays with the City).

Checklist

• Confirm whether the property is a Designated Historic Property (DHP), Potentially Designated Historic Property (PDHP), in an S-7 or S-20 zone, or within an API/ASI (check zoning map). § 17.136.023.
• Prepare Design Review application materials per § 17.136.020 (site plans, elevations, materials, context and historic-resource info).
• Evaluate whether your project meets the exemptions in § 17.136.025 (repairs that visually match; some ADU work if conforming).
• If demolition is proposed, compile economic feasibility, hazardous-condition evidence, and replacement-design quality documentation required by § 17.136.075.
• Check whether LPAB referral is likely (S-7 projects, certain S-20 projects, OS CUP projects). § 17.136.060, § 17.135.040.
• Confirm design compliance with the City’s Design Guidelines for Landmarks and Preservation Districts and any Secretary of the Interior standards called for by the project. § 17.136.070(C); § 17.100B.050(C).

Risks & Ambiguities

Plain-English Summary

If your Oakland property is a designated landmark or lies in a mapped historic overlay (especially S-7 or S-20), expect extra layers of design review for exterior changes and very high hurdles for demolition — the Planning Code requires findings about compatibility, replacement quality, and often a referral to the Landmarks Preservation Advisory Board. See the relevant design-review and landmark rules in § 17.136.020–.075 and § 17.100B.010–.050 for the detailed standards.
