Commission adopts downtown historic design standards with follow‑up to clarify storefront guidance

The San Francisco Historic Preservation Commission on April 3 voted unanimously to adopt new downtown historic design standards intended to provide clearer, enforceable guidance for storefronts, signage, awnings and temporary activations in downtown commercial districts.

Rebecca Salgado of planning staff presented the standards (Case 2023-005134CRV), which the department framed as formalizing decades of guidance and aligning local practice with Article 11 of the Planning Code and the Secretary of the Interior standards. Staff said the standards would give consistent direction to building owners, tenants and architects on acceptable materials, illumination and storefront proportions.

Public comment was supportive: Woody Labonte, president and CEO of San Francisco Heritage, said his organization had reviewed the documents and had no substantial comments, urging adoption to improve predictability for developers and to align with state housing production laws. SFNEON also expressed support for including signage standards.

Commissioners praised the clarity and graphics but flagged areas needing additional language and flexibility, particularly the storefront section and how to treat missing historic fabric. Commissioners asked staff to provide clearer language about when matching historic materials is required versus when a compatible, differentiated replacement is acceptable. Staff said the standards are intended to limit staff discretion where possible while preserving case‑by‑case flexibility, and agreed to return with edits.

Commissioner Wright moved to adopt the standards as drafted and to direct staff to return in three months with updates informed by the hearing; the motion passed unanimously 5–0.

The standards will be used by planning staff to evaluate and provide certification for common scopes of work in downtown historic buildings. Staff will return with clarifying changes and suggested edits to the storefront guidance in approximately three months.
