158 Lisbon St, San Francisco, CA 94112

The two-unit residential building at 158 Lisbon Street in the Excelsior neighborhood, owned by Cecilia Choi Ha Chan, was constructed in 1908 and has undergone several significant renovations and faced multiple regulatory challenges over the years. The property has a documented history of structural work, including foundation upgrades in 2013, stair repairs in 2007, and multiple roofing projects in 2005 and 1992. Notably, between June and July 2013, the building experienced substantial unpermitted construction activity that triggered multiple building violations, including unauthorized concrete work, new stairs, and foundation modifications, though these issues were ultimately resolved by May 2014.

A significant incident occurred in January 2007 when a water heater failure caused flooding that affected multiple units. More recently, the building has been subject to ongoing fire safety concerns, with multiple violations recorded between 2015 and 2024, including issues with exits, alarms, and sprinkler systems. There are currently three open fire violations as of September 2024 related to electrical systems, sprinkler service, and exit obstructions.

The property has also generated several maintenance requests in late 2024 regarding parking violations and tree root damage to the sidewalk, though these are administrative matters not directly related to building safety. The building's infrastructure improvements include comprehensive electrical work completed in 2007, featuring rewiring of key areas such as bathrooms, kitchen, and laundry facilities. While the property has faced various regulatory challenges, most historical violations have been addressed, with the exception of the recent fire safety concerns that remain open.
