4648-4650 Ulloa St, San Francisco, CA 94116

The property at 4648-4650 Ulloa Street is a two-unit, two-story multi-family residential building located in San Francisco's Outer Parkside neighborhood. Built in 1950 and currently owned by the Ha Su C 1998 Trust, this flats and duplex building has undergone several significant maintenance and repair projects over the past two decades. The most recent major work was completed in December 2023, involving sewer and house trap replacement.

Other notable electrical and infrastructure improvements include a 2015 service entrance repair, a 2008 roofing project (costing $8,000), and a 2006 electrical upgrade involving ground rod installation and GFCI replacements. The building's recent history shows no serious safety incidents directly affecting the structure or its occupants, though there have been numerous 311 calls in 2024 related to street-level issues. These include multiple reports of garbage and debris on or near the property, sidewalk defects, and one instance of parking on the sidewalk (which could not be validated by responding officers).

While there was one fire complaint in 2016 regarding combustible materials, it was determined to have no merit. The property has experienced two documented fire department responses: one for a malfunctioning smoke detector and another for invalid assistance, neither resulting in civilian injuries. The building's maintenance record, particularly the recent sewer work and previous electrical upgrades, suggests regular upkeep of critical systems, though the frequency of street-level complaints in 2024 indicates ongoing neighborhood cleanliness challenges.
