1660 Bay St, San Francisco, CA 94123

The 24-unit, 3-story multi-family residential building at 1660 Bay Street in the Marina neighborhood was built in 1939 and is currently owned by 1660 Bay St LLC. The building has undergone significant renovations and improvements over the past several years, with most recent major work focused on fire safety upgrades. In January 2025, a permit was filed to upgrade the fire alarm system to current codes, including installation of low frequency sounders in sleeping areas. The building has experienced multiple fire safety-related issues, with several violations and complaints in 2023-2024 related to alarm systems, sleeping area requirements, and sprinkler systems, some of which resulted in violations being issued.

There is ongoing concern about the building's exterior conditions, particularly the front stucco façade, which prompted a 2023 complaint about possible structural issues and water intrusion. The property has undergone extensive unit renovations from 2018 to 2023, including complete conversions of kitchens to bedrooms in multiple units, bathroom rehabilitations, and installation of washer/dryer facilities in units 101, 105, 206, 303, 306, and 108. Significant plumbing and electrical upgrades have been completed throughout the building, including new sub-panels, rewiring of kitchens and bathrooms, and extensive new fixture installations. The building's maintenance history shows consistent attention to updating and improving individual units, although there are recurring fire safety compliance issues that have required multiple interventions over the years.

Outside the building itself, there have been numerous parking enforcement calls in late 2024, primarily related to driveway blocking, indicating potential ongoing issues with parking in the area. The most pressing current issues revolve around fire safety compliance, with multiple violations and repair orders issued in early 2024 regarding the alarm system maintenance, sleeping area requirements, and records/UL certificate issues. The building's history shows a pattern of fire safety system inspections and corrections, with the most recent fire alarm upgrade permit indicating ongoing efforts to maintain compliance with current safety codes. While the building has had various maintenance and upgrade issues over its history, the most significant recent concerns relate to fire safety systems and exterior façade conditions.
