1664 Alabama St, San Francisco, CA 94110

1664 Alabama Street is a two-unit, two-story multi-family residential building located in Bernal Heights, owned by Lawrence I. and Susan Lessler and constructed in 1908.

The property has undergone several significant renovations over the past decades, with the most substantial recent work occurring between 2020 and 2024. This included a permitted rear yard addition in 2020 valued at $450,000, followed by extensive plumbing improvements in 2022-2023 comprising bathroom and kitchen renovations, installation of a new high-efficiency furnace, electrical rewiring, and various plumbing fixtures. Historical records show earlier modifications including horizontal expansion in 1991, illegal unit removal in 1986, and proposed but cancelled front stairs and porch work in 1986.

More recent concerns center around two sewage backup incidents in October 2024 originating from a side sewer vent, and numerous parking-related complaints between 2024-2025, including multiple reports of abandoned vehicles and driveway blocking. The building's earlier history includes a termite inspection in 1989 and a fire hazard violation related to weeds and grass in 2005, though this was resolved within the same month. The property appears to have undergone regular maintenance and upgrades over time, with the most significant recent improvements focusing on modernizing plumbing, electrical, and HVAC systems, as well as adding usable space to the structure.
