1813 Oak St, San Francisco, CA 94117

This two-story, four-unit multi-family residential building located at 1813 Oak Street in the Haight Ashbury neighborhood was built in 1953 and is currently owned by John F. and Karen M. Mulligan.

The building has experienced several significant maintenance and safety issues over its history, most notably a substantial mold problem in late 2012 that affected multiple areas throughout one apartment, including closets, bedrooms, bathrooms, and living rooms, particularly on window frames, though this was addressed through renovations completed in June 2013. In 2002-2004, the building underwent comprehensive remediation of various violations including repairs to stairs, hot water heaters, fire proofing, and security improvements such as installing self-closing devices at exterior doors and providing door viewers, all of which were successfully abated by April 2004. The building's maintenance record shows some attention to infrastructure, including building permits for bathroom repairs due to mold in 2013, though an attempt at electrical system upgrades in 2004 (New PG&E feed and installation of underground pipe) was cancelled.

More recent events from 2022-2024 indicate continuing attention to the property’s surroundings, with multiple 311 calls for general cleaning, sidewalk maintenance, and street defects around the building's perimeter, including a completed restoration project around a manhole and sewer lateral trench in September 2023. The most recent concerns involve a housing encampment report from June 2024, though this appears to be related to street issues rather than the building itself. The building's documented history shows periods of both significant maintenance challenges and sustained efforts to address safety and habitability concerns, particularly during the early 2000s and more recently with ongoing exterior maintenance.
