439-441 Union St, San Francisco, CA 94133

The five-unit, three-story multi-family residential building at 439-441 Union Street in Telegraph Hill, owned by Exemption Trust, was constructed in 1908 and has undergone several significant renovations and faced multiple maintenance challenges over the years. Most recently, in January 2025, a serious security concern was reported regarding a damaged basement door with a large hole potentially created by an intruder, compromising both security and pest control.

Earlier in 2024, the building experienced problems with heating and hot water systems, though these issues were officially abated by June 2024. The property has seen substantial improvement work, including a 2018 kitchen remodel costing $20,000 with associated electrical and plumbing work, and more extensive renovations in 2010 involving multiple units, including kitchen and bathroom upgrades with new electrical systems. The building's maintenance history shows both routine upkeep and some concerning patterns, such as a period of unpermitted electrical work in 2018, structural repairs without permits in 2009, and multiple violations related to heating and hot water systems in 2024.

Historically, there were also concerns in 2005 regarding smoke detectors and emergency exits, though these issues were marked as not active. The property has undergone various inspections and permit processes, including a 2010 effort to verify and properly label addresses for all units in the building. Regular cleaning and maintenance of common areas and the surrounding exterior have been documented through multiple 311 calls for general cleaning and waste removal between 2022 and 2024, though these appear to be routine street maintenance rather than specific building issues.
