3 Porter St, San Francisco, CA 94110

The two-unit residential building at 3 Porter Street in Bernal Heights, owned by Richard K. Lui, is a two-story flats and duplex structure built in 1916.

The property has undergone significant renovations and faced several compliance issues in recent years, with the most pressing concerns emerging in late 2020 when unauthorized work was documented, including new interior framing and plumbing modifications, which led to building violations that remain active. Since then, the property has seen substantial permitted improvements, including a 2022 project to relocate bathrooms and kitchens in both units, replace windows, and rebuild exterior stairs, followed by 2023 updates including electrical rewiring and various façade improvements.

Of particular note is a recently filed complaint in December 2024 alleging the building is in an abandoned/derelict condition with damaged walls, dilapidation, and graffiti, which marks a concerning regression in building maintenance and resident safety. The property has also experienced multiple parking violations on the adjacent public streets and some noise disturbances, though these are less significant compared to the building's structural and maintenance issues. Multiple building permits show ongoing efforts to maintain and update the property, including bathroom remodels, roof reinforcement work, and kitchen renovations, with most recent permits focusing on façade improvements and electrical upgrades.
