208-210 Flood Ave, San Francisco, CA 94112

The property at 208-210 Flood Avenue in Sunnyside is a one-story, multi-family residential building containing 2 units, built in 1911 and currently owned by John Kwong. The building has undergone several significant modifications over the years, most notably in 2017 when work was completed to legalize an unauthorized unit (Unit B) that included 2 bedrooms, 1 bathroom, kitchen, and living room, following a major violation notice.

This legalization process involved substantial improvements, including electrical upgrades with a new 200-amp service, complete electrical replacement, new furnace installation, water heater replacement, and gas line work, all totaling approximately $21,000. The building has a documented history of various permits and violations, including a significant illegal unit conversion in 2016-2017, multiple plumbing issues including sewer problems, and violations related to smoke detectors and carbon monoxide detectors. The property underwent several earlier modifications, including unauthorized room additions in 2001 (playroom, bedrooms, bathroom, and laundry room) and conversion of a commercial unit to residential use in 2001, which resulted in multiple housing code violations.

Structural work including underpinning of the east wall was completed in 1995, and various repair works were carried out through the years, including water damage repairs in 1993 and exterior wall repairs in 1987. Recent activity (2024) shows recurring issues with plumbing systems, including a notable sewage backup incident, as well as multiple parking enforcement issues in the vicinity. The building's maintenance history suggests various unauthorized modifications over the years, with significant efforts made in recent years to bring systems up to code, though some active violations related to unauthorized unit conversion remain on record.
