Augrented Insights Report

The three-story multi-family residential building at 1283-1289 Union Street in Russian Hill, owned by Arthur Woo, was constructed in 1915 and contains 4 units. The property has experienced recurring issues over the past several years, with the most pressing concerns currently centering on fire safety violations and unpermitted structures on the roof.

As of January 2025, there are active violations regarding blocked exits and roof access, with a specific violation issued in November 2024 concerning the exit to the roof. Multiple complaints from 2024 have been filed regarding hazardous conditions on the roof, including stored items, debris, and unpermitted structures, with some complaints still marked as active. The building has a documented history of maintenance issues and code violations, particularly during 2018 when multiple complaints were filed regarding unpermitted electrical and plumbing work, possible structural problems, and pest infestations.

Historical records show roof shingle replacement work was performed in 2001, and several violations related to lead paint hazards in the common areas were addressed during that same year. The property has also experienced periodic issues with parking violations on adjacent streets, as evidenced by multiple 311 calls in late 2024, though these are external to the building itself. While some past complaints have been resolved, the current situation regarding roof access and fire safety remains concerning, with open violations that require attention to ensure resident safety and regulatory compliance.
