647 San Jose Ave, San Francisco, CA 94110

The property at 647 San Jose Avenue is a two-unit, two-story multi-family residential building constructed in 1924 in the Bernal Heights neighborhood, currently owned by Louie Sue Hong. The building underwent significant renovations in the late 2000s, following major code violations identified in 2001 that documented numerous safety concerns including unapproved dwelling units, improper exiting, inadequate fire safety measures, and lack of proper heating and ventilation systems.

Between 2007-2008, substantial improvements were completed including kitchen and bathroom remodels in both units, electrical panel upgrades, and plumbing system updates, with work totaling approximately $52,000. These renovations addressed the earlier violations, with the illegal garage unit conversion being specifically noted as abated in June 2008. Prior to these improvements, the building experienced several maintenance and safety issues from 2001-2005, including unauthorized construction work, plumbing problems, and various habitability concerns.

Historical records show earlier improvements including window replacements in 1986 and reroofing work in 1993-1994, suggesting ongoing maintenance of the property over time. The most recent maintenance history available shows no building violations since 2008, though there have been several 311 calls between 2021-2024 primarily related to street cleaning and sign maintenance issues rather than building-specific problems. The extensive renovations completed in 2007-2008 appear to have resolved the major safety and habitability concerns that existed in the early 2000s, bringing the building into compliance with current codes at that time.
