740 Tennessee St, San Francisco, CA 94107

740 Tennessee Street is a 4-unit, 2-story multi-family residential building constructed in 1907, currently owned by Tn Crash Pad LLC. The property has undergone significant renovations and infrastructure upgrades over recent years, with major work completed between 2019 and 2024 including a 400-amp service upgrade, installation of new fire alarm systems, comprehensive plumbing and electrical rewiring of all units, roof deck modifications, and relocation of mechanical systems.

Recent permit activity in 2024 shows ongoing improvements with deferred work on mechanical and electrical systems for garage exhaust ($24,000) and substantial compliance work ($300,000) involving relocation of equipment, electrical meters, and modifications to building access points. The building's history includes several notable events and concerns, particularly during the 2019-2022 renovation period. These include multiple complaints about construction noise, equipment placement, and work being performed beyond permitted scope, particularly regarding the handling of concrete slab demolition and exterior work during that period.

The property has maintained building safety systems with regular fire alarm testing and sprinkler system installations, though there have been some instances of false alarms as recorded in fire incident data. Historical building violations from 2001 related to staircase repairs, ceiling issues, and fire safety equipment were all abated by March 2002. Recent planning records indicate the completion of a major renovation project that addressed several historical preservation concerns and included the installation of new mechanical systems, exterior modifications, and interior upgrades across all units.
