940 Post St, San Francisco, CA 94109

940 Post Street is a 35-unit, 4-story multi-family residential building constructed in 1912, currently owned by Crosby Apartments LP. The building has undergone several significant upgrades and renovations over the years, with the most recent major work focused on fire safety systems. In 2020-2021, the property underwent a substantial fire alarm system upgrade costing $118,000 to meet current code requirements, including the installation of low-frequency sounders.

The building's safety features have been a recurring focus, with multiple fire system violations and complaints between 2021 and 2024, though most have been addressed promptly. The property has a history of maintenance and renovation, including seismic upgrades in 1996, individual unit improvements, and common area maintenance. Recent years have seen some concerning issues, particularly in 2020, when complaints were filed regarding basement construction work being conducted without permits, plumbing problems suggesting aging infrastructure, and elevator permit expiration.

These issues have generally been addressed, with most building complaints from 2020 being marked as "Not Active." The building's history includes multiple violations between 2005 and 2005 related to fire escape maintenance and smoke detector functionality, which were resolved at that time. A 2023 fire violation regarding sleeping area requirements remains open, along with a historical violation from 2007 regarding fire protection equipment maintenance that was eventually closed. The property has experienced ongoing challenges with building systems and maintenance, as evidenced by various 311 calls in 2024 regarding debris, though these primarily relate to exterior maintenance rather than building systems.
