1129 Union St, San Francisco, CA 94109

The 6-unit, 3-story multi-family residential building at 1129 Union Street in Russian Hill, owned by Huie Crystal K & Sharon Cho, has undergone several significant improvements and faced multiple maintenance challenges since its construction in 1918. Most notably, the building completed mandatory seismic retrofitting in 2019 as a Tier 3 soft-story building, demonstrating compliance with San Francisco's earthquake safety requirements.

Recent housing concerns include persistent issues with chipping paint and lead paint concerns, with multiple complaints filed in 2023-2024, and a current active complaint from June 2023 regarding incomplete lobby work following the seismic retrofit. The building has experienced recurring maintenance issues, including a serious cluster of violations in mid-2015 that required repairs to various interior surfaces, plumbing systems, and electrical systems, though these were all abated by February 2016. The property has seen consistent infrastructure upgrades over the past decade, including furnace replacements, gas service upgrades for multiple units, and various plumbing improvements including the installation of a new water heater for all units in 2014.

Recent permits from 2023 indicate ongoing maintenance attention, including water damage repairs to the lobby ceiling. The building has encountered several tenant complaints regarding maintenance issues, including problems with flooring, plumbing, and appliances, though most historical violations have been resolved. The property has maintained its compliance with building codes, as evidenced by the completion of the soft-story retrofit program, though recent housing inspection requests indicate persistent maintenance issues requiring ongoing attention.
