1712-1722 Union St, San Francisco, CA 94123

The 14-unit, 3-story multifamily residential building at 1712-1722 Union Street in Cow Hollow, built in 1962 and currently owned by Yhk Properties LLC, has undergone several significant safety and infrastructure improvements in recent years. Most notably, the building completed mandatory soft-story seismic retrofitting (Tier 4) in 2019, which included both residential and commercial components, demonstrating compliance with San Francisco's seismic safety requirements. The building's fire safety systems have received considerable attention, with recent installations including a modern addressable fire alarm system with low-frequency horns in 2022-2023, following previous fire code violations related to emergency lighting, sprinkler service, and fire extinguisher maintenance identified in December 2019.

Several building complaints have been recorded, with the most recent being filed in January 2024 regarding noise issues and ventilation concerns from a ground-floor dry cleaner, though this complaint is no longer active. Historical complaints from 2014 indicated issues with peeling paint and potential lead hazards, while earlier complaints from 2000-2011 involved various housing and safety concerns, including unauthorized modifications and construction practices. The building's maintenance history includes plumbing work (water line replacement in 2019) and electrical system upgrades.

Recent 311 calls (2021-2024) have primarily addressed external issues such as parking violations, litter, and tree maintenance, suggesting ongoing attention to building surroundings. The property has maintained relatively good compliance with safety requirements since the resolution of earlier violations, with most recent complaints being addressed promptly. The building's management has demonstrated a commitment to maintaining current safety standards through the installation of modern systems and participation in mandatory retrofit programs, though residents have occasionally reported concerns about construction practices and building maintenance in the past. Regular inspections and prompt resolution of violations indicate active management of building safety and maintenance requirements.
