23-25 Balboa St, San Francisco, CA 94118

The four-story multi-family residential building at 23-25 Balboa Street in San Francisco's Inner Richmond neighborhood, owned by Ma Cheng and Yang Jing, was built in 1908 and has undergone significant transformations, most notably between 2008-2011. The most substantial renovation occurred in 2008 when the property was converted from a single-family dwelling to a two-unit building, including a three-story horizontal and one-story vertical addition over the existing garage, with a construction cost of $200,000.

This major renovation was followed by comprehensive upgrades in 2011, including the installation of a new fire sprinkler system ($33,500), bathroom reconfigurations on all floors ($10,000), and extensive plumbing work involving nine bathrooms, two kitchens, and various utility installations. The building received necessary safety upgrades including three new 200-amp electric meters, though these permits are currently marked as expired. Since the major renovations, the building's history has been relatively stable, with most incidents recorded through 311 calls relating to street maintenance, parking violations, and the occasional noise complaint.

Notable recent concerns include a June 2024 report of furniture debris and a January 2024 complaint about driveway blockage, though both were promptly resolved. The property's infrastructure improvements from 2008-2011 demonstrate a significant investment in safety and modernization, including comprehensive plumbing and electrical upgrades, though some permits are marked as expired and may require follow-up verification. While the building has experienced typical urban maintenance issues such as sidewalk cleaning needs and parking enforcement matters, these appear to be general neighborhood concerns rather than building-specific problems.
