159 23rd Ave, San Francisco, CA 94121

The 4-unit, 2-story multi-family residential building located at 159 23rd Avenue, built in 1963 and currently owned by the Chew Family Trust, has experienced several significant issues in recent years. Most notably, Unit #1 suffered serious water damage in early 2024, leading to multiple repair projects including drywall replacement, flooring repairs, and kitchen renovations with associated plumbing and electrical work, with costs totaling approximately $36,653.

This unit's recent problems required both water damage mitigation and compliance repairs, and there remains an active building complaint regarding damaged walls, ceilings, floors, and cabinets from the February 2024 incident. The building has a history of structural and safety concerns, including a fire incident in 2004 that required roof and electrical repairs, and multiple violations in 2003 related to fire safety and smoke detection that were subsequently resolved.

Recent external issues have been documented through multiple 311 calls between 2024 and 2023, primarily regarding parking enforcement and street maintenance, though these do not directly impact building conditions or resident safety. The property has undergone various maintenance and improvement projects over the years, including a 2008 water heater replacement and a reroofing project in 2003, and is currently facing ongoing challenges related to water damage and building code compliance.
