518-520 Taylor St, San Francisco, CA 94102

The 43-unit, 6-story residential building at 518-520 Taylor Street in Union Square, built in 1922 and currently owned by 520 Taylor Street LP, has faced ongoing maintenance and safety issues throughout 2023-2024 that warrant attention. Most concerning are recent complaints about electrical problems, with tenants reporting power outages when using space heaters and other appliances, and more recent issues with heating systems in October 2024. The building has also experienced multiple plumbing and water-related problems, including window leaks and water intrusion issues reported in late 2023 and early 2024.

Structural maintenance work has been ongoing, with a front exterior steel reinforcement repair permit issued in May 2024, following previous improvements including a fire alarm system upgrade in 2020 and elevator electrical system upgrades in 2020. The property has a documented history of fire safety violations, though many have been addressed or corrected, including issues with sprinkler systems, exit maintenance, and fire door alignments. Between April 2024 and January 2025, several fire-related complaints were filed, including issues with electrical systems and blocked exits.

The building's elevator system has required attention, with multiple incidents of passengers being trapped requiring fire department assistance, though no injuries were reported. The property's maintenance history shows regular updates to systems and infrastructure, including plumbing upgrades in 2018, though some historical permits from 2008-2011 show past compliance issues that were ultimately resolved. Recent 311 calls regarding the property have primarily focused on street-level concerns such as garbage and debris, though these are more related to the building's location than its condition.
