153-155 Silliman St, San Francisco, CA 94134

The two-unit residential building at 153-155 Silliman Street in the Portola neighborhood, owned by Christopher Cardenas, is a two-story flats and duplex structure built in 1900. The property has experienced significant maintenance and safety issues over the past few years, with particular concerns regarding stair safety. Most notably, there have been multiple permit attempts to address rear stairs replacement between 2023-2024, including recent permits filed in October 2024.

A serious cluster of violations was documented in May 2024, including issues with water heaters, sink repairs, tub/shower repairs, smoke detection systems, carbon monoxide alarms, and emergency egress windows. Additional active complaints from 2024 suggest unauthorized utility connections between units and unpermitted construction work, including alleged asbestos removal without proper certification. The building has undergone several renovation attempts, including interior remodeling of the first-floor unit in 2022, bathroom fixture updates, and roofing work in 2022. Multiple permits were issued and revised regarding stair repairs, window replacements, and general building maintenance.

The property has also faced infrastructure challenges, with three sidewalk defect complaints recorded in late 2024, though these were ultimately found to have no conditions requiring action. Recent maintenance activity includes plumbing upgrades, with permits issued in April 2024 for new shower pans and a wall-mounted water heater replacement, as well as a new furnace installation. The building's history includes a fire code violation from February 2020, though this appears to have been resolved. The property has undergone various repair and upgrading efforts throughout its history, including stair construction in 1997, but recent years have shown a pattern of recurring compliance issues and unpermitted work that has resulted in multiple active violations.
