433 Corbett Ave, San Francisco, CA 94114

The 433 Corbett Avenue property is a three-story, two-unit multi-family residential building located in the Clarendon Heights neighborhood, built in 1908 and currently owned by the Cooper Worcester Family Trust. The building's maintenance and improvement history includes several significant renovations and some concerning compliance issues. Major permitted improvements have included basement remodeling for storage and bathroom/kitchen updates in 1995, aluminum window installations in 1988-1989, a gas houseline extension in 2011 for both 433 and 435 Corbett, and a 200-amp underground electrical conversion in 2004.

Of particular concern are two building complaints: one in 2014 regarding unpermitted roofing work, and another in 1994 involving unauthorized deck construction and basement room modifications, though the latter was eventually abated in 1996. Additionally, a short-term rental violation was recorded in the planning records, related to both 433 and 435 Corbett Avenue. Recent activity at the property has been relatively minor, with several 311 calls primarily concerning street cleaning issues, including a Christmas tree pickup in 2023, and some reports of hazardous materials (glass) on the street in 2009 and 2014.

The building has experienced two fire department responses: one for a carbon monoxide detector activation (malfunction) and another for assisting an invalid, neither resulting in civilian injuries. The property's permit history shows regular maintenance and upgrades, though the presence of multiple building complaints regarding unpermitted work raises some concerns about past compliance with construction regulations. The most recent major building system upgrades (electrical and plumbing) were completed over a decade ago, with no recent permits on record for significant improvements or repairs.
