336 Chestnut St, San Francisco, CA 94133

336 Chestnut Street is a three-story, two-unit multi-family residential building constructed in 1971 in the Telegraph Hill neighborhood, owned by the T Michael Harrison Revocable Trust. The property underwent significant renovations in 2001, including structural improvements such as the installation of a steel frame to brace the second floor, additional interior stairs between the first and second floors, and various aesthetic upgrades in both living units. Earlier modifications included lowering windows at the rear top floor in 2009 to match existing windows.

The building's history includes one notable housing complaint from 1995 regarding alleged illegal units, though this was resolved and closed in 2009. Recent activity at the property has primarily involved parking-related issues, with multiple complaints about driveway blocking between 2019 and 2024. There have also been two noise-related complaints in 2024 (one still open) and a building inspection request in 2020 that was resolved.

A significant regulatory matter was the application for Open Space and Dwelling Unit Exposure Variances, which sought to legalize a ground floor dwelling unit; this was ultimately approved, indicating efforts to formalize previously unpermitted space. The building has undergone various permitted modifications over the years, including exterior improvements like ceramic tile decking installation and wood siding replacement, as well as interior renovations such as partition removals and kitchen relocations. The most recent parking-related incidents were documented in 2024, including citations for vehicles blocking the driveway.
