140 Wood St, San Francisco, CA 94118

The 6-unit, 3-story multi-family residential building at 140 Wood Street in Lone Mountain, owned by the Jang Family Trust, was constructed in 1960 and has undergone several significant events over its lifetime. Most notably, in October 2023, a mandatory fire alarm upgrade was filed to meet current fire marshal codes, including updating the fire alarm panel, adding horns in units, and installing a wireless communicator. The building has experienced multiple fire alarm-related incidents, including false alarms, malicious false alarms, and a malfunction in 2017 that required correction.

A documented instance of mold and dry rot was reported in 2016, and in 2005, the property underwent reroofing work costing $10,500. The building has a history of various housing code violations, particularly in late 2002 and late 2005, though all these issues were resolved by November 20, 2002. Violations from 2002 included problems with self-closing doors, gas metering equipment, and plumbing/electrical systems, while 2005 violations noted issues with ceiling repairs and fire escape ladder maintenance.

There was also a concerning report in 2002 of black smoke coming from a heating vent. The building has experienced numerous street-related issues in recent years, with multiple reports of abandoned furniture and debris on the sidewalk between 2022 and 2025, though these were addressed promptly. Two parking enforcement incidents related to driveway blocking were reported in 2020. The property's most recent documented building permit activity is from October 2023, focusing on crucial fire safety upgrades, which suggests ongoing attention to building safety systems.
