18-20 Chenery St, San Francisco, CA 94131

The property at 18-20 Chenery Street in Glen Park is a two-unit, two-story multi-family residential building constructed in 1908, currently owned by the Tania M Shertock Revocable Trust. The building has undergone several significant renovation attempts over the past decade, most notably an effort to add an ADU (Accessory Dwelling Unit) in 2017-2018, which included comprehensive structural improvements, bathroom, bedroom, and kitchen installations, though this project was ultimately cancelled.

During 2018, the property experienced flooding concerns that prompted the installation of drainage systems, including trench drains at the garage and front door, along with a sump pump installation at the rear, which are documented through both building and plumbing permits. More recent improvements include a completed upgrade to a 200 amp electrical service in July 2019, though a related electrical permit for new unit wiring from October 2018 expired.

The building experienced a sewage backup incident in April 2023, which was resolved, and there are ongoing concerns with a collapsed sidewalk noted in July 2023. Historical records show multiple parking enforcement issues in the vicinity between 2018-2020, including several instances of blocked driveways and sidewalk parking, though these are unrelated to building conditions. The property's infrastructure has received attention over the years, with various plumbing updates including sewer trap replacement in 2014 and bathroom remodels, indicating ongoing maintenance of essential systems.
