140 Haight St, San Francisco, CA 94102

140 Haight Street is a 12-unit, 3-story multi-family residential building constructed in 1905, currently owned by Susan M. Mitchell and located in Hayes Valley. The building has undergone several significant improvements in recent years, including a major fire alarm system upgrade in late 2023 costing approximately $27,880 to comply with current fire code requirements, following an earlier 2021 installation of low frequency sounders and replacement of the fire alarm control panel costing $36,000.

The building received a new roof in 2022 at a cost of $19,875, and Unit 9 underwent a kitchen and bathroom remodel in early 2022 costing $30,000, with associated plumbing and electrical work properly permitted and completed. However, there are several active building violations from July 2023 that require attention, including issues with the fire escape drop ladder, gas utility shutoff tools, and various compliance affidavits. The building's maintenance history shows periodic attention to infrastructure needs, including a sewer line replacement in 2014 and a series of fire safety inspections and repairs between 2004 and 2005.

While there have been multiple fire alarm system activations and some fire safety violations over the years, most have been related to system malfunctions or maintenance issues rather than actual emergencies, with no civilian injuries reported in any of the documented incidents. A notable complaint from 2020 highlighted concerning tenant-manager interactions and maintenance issues, though this complaint is no longer active. There have been ongoing issues with graffiti and sidewalk maintenance in the surrounding area, as evidenced by multiple 311 calls throughout 2024, though these are external to the building itself.
