631-633 15th Ave, San Francisco, CA 94118

The 2-unit multi-family residential building at 631-633 15th Avenue in the Central Richmond neighborhood, owned by Mina Choo and Minsik Pak, was constructed in 1921 and is classified as a Flats & Duplex building with two stories. The property underwent significant renovations in 2013-2014, with major work including comprehensive updates to both units' kitchens and bathrooms, creation of a recreation room in the garage, installation of new interior stairs, and structural modifications to improve garage access, all completed at a cost of $210,000.

Additional improvements during this period included new plumbing systems for both units, electrical upgrades including a complete rewiring, installation of new water heaters, and bathroom renovations, supported by the replacement of six street-facing windows with wood windows. More recently, the building has seen sustainable upgrades with the installation of solar power systems in 2022, including two separate rooftop solar installations (2.8 kW and 3.8 kW) with Tesla Powerwall energy storage systems. Historical records show the building underwent reroofing work in 2003, though this permit is marked as expired.

The property has experienced minimal issues over the years, with the most significant being a sewage backup incident in 2012, and occasional parking-related concerns in the vicinity. The building was legally converted to two condominiums under the DPW Lottery Bypass program, with the conversion approved by planning authorities. Recent 311 calls have primarily related to street cleaning and parking matters rather than building-specific issues, suggesting good maintenance and management of the property.
