107-109 Flood Ave, San Francisco, CA 94131

The 105-109 Flood Avenue property in Sunnyside, owned by Liu De Teng, is a 2-unit, 2-story multi-family residential building constructed in 1907. The building has undergone significant renovations and improvements over recent years, with the most substantial work occurring in 2024, including bathroom remodels, furnace replacements, and the installation of tankless water heaters in units 107 and 109.

A notable project involved converting the existing detached garage into an ADU (Accessory Dwelling Unit) in 2021-2024, which included substantial structural work such as new footings, wall studs, and roof rafters, costing $16,000. The property has been actively maintained, with several plumbing and electrical upgrades completed or in progress, including heating system installations and bathroom/kitchen renovations. The building has faced several compliance issues, particularly in 2018, when violations were documented regarding mold and mildew, heating system deficiencies, fire safety concerns, and questions about unpermitted modifications, including a possible illegal third unit and unauthorized dwelling units.

While many of these 2018 violations were resolved by October 2018, a significant concern remains regarding the status of the converted garage, which was the subject of an active building complaint as of 2018. Recent permit activity indicates ongoing improvements to the building's systems and structure, suggesting the owner is actively addressing maintenance needs. The property has experienced multiple 311 calls in late 2024 regarding garbage and debris removal, though these appear to be unrelated to building conditions.
