442 10th Ave, San Francisco, CA 94118

The property at 442 10th Avenue in San Francisco's Inner Richmond neighborhood is a two-unit, two-story multi-family residential building constructed in 1920, currently owned by Steven B C & Kitty Cheung K. The building's history reveals several significant events, particularly regarding unit modifications and structural maintenance. In 2021, an active complaint was filed regarding an allegedly unauthorized in-law unit located behind the garage, which raises potential concerns about building code compliance and tenant safety.

In 2018, there was an attempt to add a basement unit with two bedrooms and one bath, though this permit application was ultimately withdrawn. The building has undergone several maintenance and improvement projects over the years, including a completed dry rot repair and stucco replacement in 1995, and an expired permit for a horizontal addition from 1990 valued at $83,300. The property has experienced some public infrastructure issues in its vicinity, with recent reports including a street maintenance request in 2024 and an outstanding curb defect complaint from 2020.

Previous issues such as an abandoned garbage incident in 2023, and a sidewalk defect investigation in 2013 (which was resolved with no violations found), have been addressed. The building has been subject to various planning and inspection records, including a closed investigation for alleged unauthorized short-term rental use, which found no violations. While the building's structural issues appear to have been addressed based on historical permit completion statuses, the active complaint regarding the unauthorized unit and the history of attempted basement modifications suggest ongoing concerns about proper unit configuration and adherence to current building codes.
