240 4th St, San Francisco, CA 94103

240 4th Street is a 30-unit, 7-story multi-family residential building constructed in 1997, currently owned by Tenants & Owners Dev Corp. The building has undergone several significant permit-related changes since its construction, including tenant improvements to office space in 2002 (completed), and a horizontal addition followed by final inspections in 2008-2010.

More recently, in 2024, there was a notable tenant improvement project involving the installation of new interior walls, floor finishes, walk-in coolers, and freezers, conducted under separate electrical, mechanical, and plumbing permits for a catering establishment. The building has experienced recurring fire safety issues over the past decade, with multiple fire code violations documented between 2020-2024, though all violations have been subsequently abated. Fire incidents have primarily involved false alarms, elevator rescues, and unintentional alarm activations, with no reported civilian injuries.

In recent months (2024-2025), there have been various street-level maintenance and public safety issues in the vicinity of the building, including graffiti, sidewalk flooding, and debris removal concerns, though these external matters are not directly related to building operations. A significant improvement was made in October 2024 with the abatement of several fire safety violations related to the ERRCS permit, records/UL certificate, and other systems. The building's maintenance history shows regular attention to permit requirements and code compliance, though the frequency of fire system-related issues suggests ongoing challenges in this area have required consistent monitoring and resolution.
