3730-3734 Judah St, San Francisco, CA 94122

The property at 3730-3734 Judah Street in San Francisco's Outer Sunset neighborhood is a two-unit, two-story multi-family residential building constructed in 1956, currently owned by Kathy Ai Gen Tong. The building has undergone significant and complex renovations over the past decade, including a major 2015-2019 project to add an ADU and modify various interior elements, which was initially completed without proper permits, leading to multiple complaints and violation notices.

The property has experienced several safety concerns and building code issues, notably in 2021 when there were complaints about massive unauthorized excavation work affecting neighboring properties and unauthorized removal of rear stairs. Recent improvements include a comprehensive renovation of unit 3734 in 2023 ($35,000), and ongoing work as of 2024 involving utility upgrades and plumbing fixture replacements, including new fire sprinklers installed in 2022.

Historical issues included multiple violations for unpermitted construction and electrical work in early 2015, which remain active in the records, though the most recent complaint regarding exit maintenance was corrected in 2022. The building's mechanical systems have been upgraded significantly, with recent permits showing replacement of various electrical fixtures, appliances, and safety systems. The property has also had several maintenance issues documented through 311 calls, including parking violations and sewer problems, though these are generally not directly related to building safety or habitability.
