160 Connecticut St, San Francisco, CA 94107

The 12-unit, three-story multi-family residential building at 160 Connecticut Street in Potrero Hill, owned by Masu Abe Revocable Trust 19, has undergone significant modifications since 2018, most notably the addition of two ADUs (Accessory Dwelling Units) numbered 13 and 14, completed in 2018-2019. The building's fire safety systems have been a consistent focus, with multiple upgrades including a new fire alarm system in 2018, sprinkler installations, and subsequent monitoring system improvements.

Recent fire safety violations were issued in September 2023 related to sprinklers, extinguishers, and combustible storage, though these were abated promptly. The building's history includes several fire safety-related issues, with multiple violations and complaints between 2009 and 2024 concerning extinguishers, sprinkler systems, exit maintenance, and combustible materials. A significant retrofit was completed to address structural concerns under San Francisco's Soft Story Program (Tier 3), achieving compliance with a Certificate of Final Completion issued.

Recent maintenance and service requests from 2022-2025 have primarily involved exterior issues such as sidewalk cleaning and graffiti removal, with two recent 311 calls regarding sewage backup and garbage/debris issues in early 2024. The building has undergone regular routine inspections by housing authorities, with the most recent common area complaint from October 2023 currently marked as active. While historical violations suggest previous safety concerns, recent records indicate efforts to maintain and upgrade building systems, though attention to fire safety compliance appears to remain an ongoing requirement.
