411-413 Bowdoin St, San Francisco, CA 94134

The property at 411-413 Bowdoin Street in the Portola neighborhood is a two-story multi-family residential building owned by the Zeng Family Trust, constructed in 2010 following the demolition of two previous commercial buildings on the site. The structure, which has undergone several modifications since its completion, was originally built as a single-family dwelling with garage space in 2008-2009, with construction costs totaling $504,000.

Between 2010 and 2014, various modifications were implemented including revisions to bedroom layouts and the addition of kitchen facilities, with the most recent significant work being completed in 2014 involving stair enclosure upgrades for safety compliance, including one-hour rated walls and doors. The building's infrastructure was substantially upgraded in 2009 with the installation of a 200-amp electrical service and comprehensive electrical systems including outlets, lighting, and appliance connections. Plumbing improvements were completed during the same period, including the installation of three bathrooms and associated fixtures.

Recent maintenance concerns have primarily involved exterior issues, with multiple 311 calls in 2024 regarding street cleaning and debris removal, including reports of abandoned furniture and appliances. The property has experienced recurring issues with blocked driveways, with three documented cases between 2022 and 2024 resulting in citations, though there is an open case from August 2022 regarding a damaged tree from vandalism. The most recent building-related service request was recorded in September 2024 for environmental health concerns, though this request has been marked as "Closed Accepted."
