3145-3147 Fillmore St, San Francisco, CA 94123

The three-story, seven-unit apartment building at 3145-3147 Fillmore St in Cow Hollow, owned by Terence C P & Amy Chu Chuan, was constructed in 1912 and has undergone several significant renovations and faced critical safety issues over recent years. Most notably, in January 2022, there was a serious carbon monoxide leak in Unit 6 (3rd floor) linked to faulty gas water heater ventilation, which was subsequently documented as a violation requiring correction by December 2022. The building completed mandatory soft-story retrofit work in 2018, demonstrating compliance with seismic safety requirements.

Recent improvements include a restaurant remodel in late 2023 with ADA bathroom upgrades and new kitchen equipment, followed by the installation of a fire suppression system in 2024, though a multiple fire code violation was noted in April 2024. The property has experienced recurring issues with the ground floor commercial space, including multiple complaints about vacancy between 2018-2024, and faced plumbing and electrical challenges, such as water heater venting problems in 2022 that required multiple permits to address. Recent maintenance and improvements include reroofing work in 2023, repair of water-damaged stucco walls in 2022, and various plumbing and electrical upgrades.

The building has a history of fire safety compliance issues, with violations in 2006, 2017, and most recently in 2024 requiring attention to alarm systems and fire safety equipment. The property's gas infrastructure received attention in 2022 following the carbon monoxide incident, with permits issued for new water heater vents and gas line updates. External to the building, there have been numerous 311 calls regarding street cleaning and sidewalk maintenance in recent months (2024), though these are more related to public space maintenance than building conditions. The current status of the building shows active permits and recent improvements, though the 2024 fire code violation indicates that there are still safety compliance issues requiring attention.
