2475-2477 Vallejo St, San Francisco, CA 94123

The two-unit building at 2475-2477 Vallejo Street in Pacific Heights is a two-story flats and duplex structure built in 1918, currently owned by Thomas W & Maggie K Chan 20. Since 2012, the property has undergone substantial renovations, including a comprehensive $150,000 remodel of two kitchens, four full bathrooms, and two half bathrooms, along with window replacements, electrical upgrades, and plumbing improvements. In 2010, the property had to address safety concerns when an illegal deck was removed, and security guard rails were installed to comply with building codes.

The building experienced multiple fire safety system issues between 2017-2018, including violations related to sprinkler/standpipe systems and alarm systems, though all were eventually resolved. The property has had seven fire alarm incidents recorded, all determined to be false alarms or system malfunctions, with no civilian injuries reported. Recent permits show maintenance work continuing through 2013, including window replacements, and the property has had various infrastructure improvements such as new heating systems and electrical upgrades.

There was a proposal in 2007 to convert the two-family dwelling into a single-family home, but this application was withdrawn. The building's recent history shows no major safety violations or resident complaints, though there have been multiple parking enforcement issues in the surrounding area as evidenced by 311 calls throughout 2024. The property has undergone proper condominium conversion processes, with records showing both a withdrawn and an approved application for conversion.
