483-485 Oak St, San Francisco, CA 94102

The property at 483-485 Oak Street is a two-unit, two-story multi-family residential building located in Hayes Valley, constructed in 1890 and currently owned by Bradley C Bombola and Coleman. The building has experienced significant structural and safety issues in recent years, most notably in 2022 when unauthorized removal of a load-bearing wall during kitchen remodeling led to substantial settlement problems, including cracks in walls and floor sagging. This triggered multiple Notices of Violation (NOV) and required several subsequent repairs, including the 2023 removal of decking debris from the egress to garage, installation of new guardrails, and chimney repairs, costing $6,500.

Other notable improvements include a $35,000 bathroom and kitchen remodel in 2022, installation of a tankless water heater in 2021, and various plumbing and electrical upgrades, though several of these projects faced permit compliance issues. The building has a documented history of compliance challenges, particularly in 2021-2022, including unpermitted electrical work, plumbing installations, and unauthorized modifications to building egress. These issues began to be addressed following the 2022 NOV, with multiple permits and repairs completed throughout 2022 and 2023 to restore structural integrity and safety features.

Recent maintenance work has included interior unit improvements such as kitchen and bathroom remodels, and the property has generally shown more active compliance with building requirements in the past year. External factors affecting the property include several recent parking violations and sidewalk cleaning issues, though these are not directly related to the building's structural or safety conditions. The property had one minor fire-related incident in 2021 regarding blocked exits, which was referred to the Department of Building Inspection.
