2253-2255 Bay St, San Francisco, CA 94123

The two-unit residential building at 2253-2255 Bay Street in the Marina, owned by Tam Thomas & Gladys, has undergone significant renovations since its construction in 1927. Most notably, in 2022-2023, substantial improvements were made to enhance the property, including the installation of new stairs between floors, the conversion of a window to a French door, removal of a load-bearing wall, and relocation of HVAC systems. These modifications were accompanied by updates to electrical systems, including a new 5.6 kW solar panel installation in May 2023, and plumbing improvements including water supply pipe relocation and water heater installations.

The building has a history of electrical and plumbing upgrades, with complete rewiring of both units (including installation of subpanels) and comprehensive bathroom remodeling work completed between 2006-2008, though some earlier permits from 2006 and 2008 show as expired. The property has experienced regular maintenance and upgrades, with particular attention paid to safety features including the installation of smoke detectors and upgraded electrical circuits. There have been minimal resident safety concerns, though a June 2024 mechanical equipment noise complaint remains open.

Previous issues included a collapsed utility vault cover in 2012, which was resolved, and various parking-related incidents near the property. The building underwent thorough inspections regarding potential unauthorized dwelling unit (UDU) modifications, with records indicating no evidence of UDU occupancy was found. Recent maintenance activities, including the 2022-2023 improvements, appear to have been properly documented and permitted, suggesting ongoing investment in maintaining and upgrading the property infrastructure while addressing any previous code compliance concerns.
