462 Cambridge St, San Francisco, CA 94134

462 Cambridge Street is a two-unit multi-family residential building located in the Portola neighborhood, constructed in 1944 and currently owned by Angela Jarquin. The property has undergone several significant modifications, most notably in 2015-2016 when the ground floor unit was legalized following a series of building violations recorded in April 2015. These violations included unauthorized construction of an additional dwelling unit, unapproved plumbing and electrical work, and occupancy issues.

The legalization process involved multiple permits totaling approximately $85,000, during which two windows were added, and several unauthorized structures were modified or removed. More recent improvements include a gas line extension in October 2024, indicating ongoing infrastructure upgrades. The building has experienced various maintenance and compliance issues over the years. There were multiple fire code violations noted in 2023-2024 related to the alarm system, sprinkler obstructions, electrical conditions, and other safety concerns, all of which were subsequently abated.

Tenant-related complaints have included mold issues in 2015, though these were reportedly addressed. The property has generated several 311 calls in early 2025 regarding various street maintenance issues, including sidewalk defects and sewer vent cover problems, which remain open. Additionally, there are recent fire alarm activations and CO detector incidents recorded, though none resulted in injuries or indicated serious safety concerns. The building's history shows a pattern of unauthorized modifications being brought into compliance, with the most significant being the legalization of the second unit in 2015-2016, which was completed successfully and received proper permits.
