310 Graystone Ter, San Francisco, CA 94114

The 6-unit, 2-story multi-family residential building at 310 Graystone Terrace in Twin Peaks, owned by Germano Jean, has undergone several significant modifications since its construction in 1958. Most notably, the building achieved compliance with San Francisco's mandatory Soft Story Retrofit Program, completing the $70,000 retrofit work in 2023, which included obtaining a Certificate of Final Completion (CFC) after resolving a violation issued in October 2019 related to the retrofit requirements.

Recent improvements include a filed permit from March 2023 to convert an existing garage into a 556 sq ft studio ADU. The building's maintenance history shows attention to infrastructure, with completed electrical work in 2005 for underground terminal pullcan installation, though two earlier permit applications from 1984 and 1988 for room additions and deck modifications respectively were cancelled.

The property has experienced various maintenance and regulatory issues over its history, with the most significant being the Soft Story Retrofit compliance violation in 2019, which was eventually resolved. Other past concerns included a 2009 fire complaint regarding combustible materials that was determined to have "no merit." The building's recent history shows relatively few serious issues, though there have been multiple 311 calls in the surrounding area between 2019 and 2024, primarily regarding street cleaning and parking enforcement matters, none of which directly indicated building-specific problems. The most recent building modification, the proposed ADU conversion, suggests ongoing investment in property improvement by the current owner.
