638-642 Balboa St, San Francisco, CA 94118

This three-unit, three-story multi-family residential building, located at 638-642 Balboa St in San Francisco's Inner Richmond neighborhood, was built in 1906 and is currently owned by Alphonse Jun Wu. The property has undergone several significant renovations, most notably in 2010-2011 when substantial improvements were made to Unit 640, including kitchen relocation, bathroom remodels, and electrical upgrades totaling approximately $68,000.

Earlier maintenance work addressed structural issues, including stair repairs in 2001-2002 due to rotting, and a reroofing project completed in 1997. The building had two routine housing inspections in 2002 and 2015, which resulted in several fire safety violations including the need for fire extinguishers, structural maintenance affidavit, and egress clearance - all of which were abated by January 2016. More recent history shows ongoing maintenance challenges with waste management, as evidenced by multiple 311 calls throughout 2024 regarding improper toter placement and abandonment issues.

There are also two active plumbing complaint cases from 1998 regarding unpermitted plumbing work, though these appear to be quite old given their age relative to the current date. The property had two noise complaints recorded in 2021-2022 related to amplified sound and excessive noise, while a defaced parking sign was reported and resolved in 2023. The building's maintenance record shows periodic attention to both routine upkeep and larger renovations, with all recent housing violations having been promptly addressed in accordance with regulations.
