400-402 Plymouth Ave, San Francisco, CA 94112

The two-unit, two-story residential building at 400-402 Plymouth Avenue in Oceanview, owned by Huang Xiao Ying, was constructed in 1948 and has undergone several significant modifications over its lifetime. Most notably, in 2019, the property underwent a significant exterior renovation when the owner replaced plastic siding with James Hardie cement boards, a project completed in February 2019 at a cost of $15,000.

The building's interior was expanded in 2004 with the addition of two bedrooms, a full bath, and a laundry room on the ground floor, along with corresponding electrical work including the installation of 7 lights, 8 switches, 14 receptacles, and 5 circuits. The property has experienced some compliance and safety concerns in recent years, particularly regarding unauthorized modifications. In 2014, there were complaints about an illegal unit built over the garage without permits, and similar concerns were documented in 2013 regarding the basement area, though these complaints are now listed as not active.

There have been recurring maintenance issues documented through 311 calls, primarily relating to street cleaning and debris removal between 2023-2025, including multiple reports of loose garbage, furniture, and other debris. The property has also generated several parking enforcement calls between 2019-2023, involving vehicles blocking driveways or parking on sidewalks, resulting in at least two citations being issued. Additionally, there were multiple street space permits issued between late 2018 and 2019, though these permits had minimal cost ($0 or $1) and their specific purpose is not detailed in the records.
