The Story So Far

The proposal at 237 Sanchez St would replace the property’s circa-1900 house and in-law unit with a 4-story apartment building containing 5 units and a basement. The tracker records the project as entitled in December 2022 through standard entitlement and classifies all 5 units as affordable. Available unit-mix data identifies 1 two-bedroom unit.

The existing house sold for $1.9 million in July 2018 after marketing described a Victorian-style home with an unlegalized two-bedroom in-law unit, according to SocketSite. Plans later drew public opposition. A January 23, 2025 letter published by 48 Hills criticized the demolition as part of a broader pattern of replacing sound housing with expensive new units.

The Planning Commission hearing moved from January 23, 2025, through February 27 before reaching March 6, 2025. Planning staff then recommended conditional approval and reported that the project was exempt from CEQA. Renderings published by SFYIMBY in January 2025 identified Tony Phan as the owner and Inncon Design as the architect. At that time, permits dating to October 2020 remained unissued, and no construction cost or groundbreaking date had been announced.

The latest step came on August 25, 2026, when applicant Kim, Kevin, working with HAWK N. LEE, P.E., filed new-construction permit 202608257096. The filing declares a $1.5 million value. The permit remains in review under planner Kurt Botn, with no issuance or completion date recorded. The parcel still appears to retain the existing house, and research found no construction start.

The tracker counts 4 prior permits at the parcel. Its feasibility model evaluates a 3-unit scenario at a 3.1 yield on cost, below the required 6.5 by 339 basis points. The surrounding Castro/Upper Market pipeline contains 33 projects and 802 units.
