453-463 Union St, San Francisco, CA 94133

The four-story, seven-unit multi-family residential building at 453-463 Union Street in Telegraph Hill, owned by Tan Chee Yong & Cecilia C, was constructed in 1910 and has undergone several significant improvements and faced various challenges in recent years. Most notably, the building completed its mandatory soft-story seismic retrofit program (Tier 4) with a CFC issued, demonstrating compliance with important safety requirements.

The property has undergone multiple infrastructure improvements, including a $3,500 in-kind back stair repair completed in 2022, substantial sewer system work in 2021 including installation of a house trap, and various electrical upgrades between 2013-2019 including new circuits for ADA compliance and lighting improvements. The building has faced several building violations and complaints, particularly in 2019-2022, including issues with a malfunctioning bathroom ceiling and light fixture, vacant storefront violations, and a period without adequate heat. A routine inspection in 2022 revealed multiple compliance issues related to fire safety and utility equipment, though these were subsequently addressed and abated.

The property has also required various permits for utility work, plumbing renovations, and electrical upgrades over the years, indicating ongoing maintenance and improvements. Recent 311 calls between 2023-2024 suggest ongoing issues with garbage and debris management in the vicinity of the building, though these are primarily street-related matters rather than direct building maintenance concerns. The building's permit and violation history shows a pattern of responsive maintenance and compliance with regulatory requirements, with most issues being promptly addressed.
