453 Buena Vista Ave, San Francisco, CA 94117

The property at 453 Buena Vista Avenue is a three-unit, three-story multi-family residential building constructed in 1910 and currently owned by Xu Yingnan. The building has undergone significant renovations and improvements over the past several years, with the most substantial work occurring between 2017 and 2023. In 2017, a major renovation was initiated costing over $1.18 million, which included adding a new level, installing a car stacker for two cars, and modernizing the units.

This work included the installation of a comprehensive NFPA-13R fire sprinkler system throughout the building, completed in 2020 at a cost of $53,600. The building has experienced several notable events related to safety and compliance. In 2020, a complaint investigation revealed that demolition work had exceeded approved permits, including the unpermitted removal of entire facade sections and second-floor joists.

This led to additional inspections and the necessary completion of updated demolition calculations in 2021 to satisfy compliance requirements. The property has also undergone various infrastructure improvements, including the installation of new mechanical systems, plumbing upgrades, and electrical work, with particular attention to fire safety systems such as smoke detectors and monitoring equipment. While the building has had several building complaints regarding construction practices in 2020 (particularly during the shelter-in-place period), most issues appear to have been resolved through proper channels. The most recent permits from 2023 indicate ongoing commitment to building maintenance and system upgrades, including fire safety improvements.
