1506-1508 Underwood Ave, San Francisco, CA 94124

The property at 1506-1508 Underwood Avenue is a two-unit, two-story multi-family residential building constructed in 1907, currently owned by the Yin Kwan Tam Family Trust. The building has undergone significant renovations between 2020-2021, including substantial interior remodeling and system upgrades, with work totaling approximately $420,000. This renovation included adding new bathrooms and closets, relocating bedrooms, and creating a master suite in the attic, along with electrical rewiring and new furnaces installation.

The exterior received attention as well, with staircase redesigns and siding repairs completed in compliance with previous violations from 2015. The property has a documented history of maintenance issues and violations, particularly prior to the recent renovations. Numerous complaints about blight, including peeling paint, broken windows, and pest infestations, were filed between 2015-2019, leading to multiple Notices of Violation.

The building had active violations as of late 2015 related to various building, plumbing, and sanitation issues, including problems with stairs, windows, bathroom facilities, and lead paint hazards. Several fire safety concerns were also recorded between 2006-2018, primarily related to combustible materials and vegetation near the structure. The recent renovation period (2020-2021) appears to have addressed many of the building's prior deficiencies, though there are some ongoing concerns noted in recent 311 calls regarding garbage and debris on the property as of early 2025.
