320 Hamilton St, San Francisco, CA 94134

The two-story, four-unit multi-family residential building at 320 Hamilton Street in Portola, owned by Tov Foan Yang, was constructed in 1963 and has undergone several important maintenance and improvement projects over its lifetime. In 1997, the building underwent significant repairs including dry rot repairs, reroofing, and the replacement of three windows with double-glazed units, all of which were successfully completed. The building experienced a cluster of safety violations in early 2001, which were all promptly addressed and abated by March 14, 2001.

These violations included stair repairs, fire escape maintenance, handrail repairs, fire extinguisher servicing, and modifications to roof deck safety features. A routine fire alarm system inspection in March 2017 resulted in corrected conditions. More recently, there is an active complaint filed in December 2024 regarding an unpermitted deck addition, which remains unresolved as of the latest available data.

The building's maintenance and violation history shows a pattern of addressing issues in a timely manner when they arise, particularly during the early 2000s when multiple safety concerns were identified and corrected. The most recent documented building-related issue pertains to a potentially unauthorized structure modification from 2024, though no resolution status is currently available. The surrounding area has experienced various municipal service calls over the years, primarily related to street cleaning, abandoned vehicles, and waste management, but these external issues do not directly impact the building's residential conditions or safety.
