1263-1267 Bay St, San Francisco, CA 94123

The property at 1263-1267 Bay St is a two-story, three-unit multi-family residential building located in the Marina neighborhood, built in 1924 and currently owned by the Attilio J Cosgrove Revocable Trust. The building underwent significant safety and modernization upgrades in 2013, including the installation of a comprehensive fire sprinkler system throughout all floors (88 heads total) with associated underground fire services, new monitoring systems, and a heat detection system. Major interior improvements were also completed in 2013, including the addition of a private roof deck, modifications to window layouts, and updates to living spaces in multiple apartments.

The building received substantial plumbing and electrical upgrades during this period, including new kitchens, bathrooms, and laundry facilities in all units, as well as furnace and water heater installations. Historical records indicate past maintenance issues that have since been resolved. These include plumbing and electrical violations, lighting problems, and structural concerns such as stairs requiring repairs - all of which were abated by 2009.

More recent maintenance activities have centered around external issues, with several 311 calls regarding driveway blocking and street cleaning matters in the last few years, though these are routine urban living concerns rather than building-specific issues. The property has maintained active compliance with safety upgrades, particularly with the comprehensive fire safety systems installed in 2013, which included over 88 sprinkler heads, heat detectors, and new monitoring systems, demonstrating an investment in resident safety infrastructure. Recent planning records indicate a proposed but disapproved variance related to parking requirements when considering the addition of a third dwelling unit, though an earlier proposal for horizontal additions and interior modifications was approved.
