527-531 Union St, San Francisco, CA 94133

The property at 527-531 Union Street is a three-story multi-family residential building located in Telegraph Hill, consisting of four units and owned by JV&Y LLC. Built in 1906, this flats and duplex structure has undergone several significant improvements in recent years. Most notably, in 2021, two windows were replaced at the back of the house, and in 2016, there was a substantial structural upgrade involving the replacement of wood posts and beams with steel support systems.

A comprehensive renovation was completed in 2015, including kitchen and bathroom remodels, window replacements, reroofing, and an electrical system upgrade to a 200-amp underground service with five meters. These improvements collectively indicate active maintenance and upgrading of the building's systems and structures. The building has a history of addressing safety concerns, particularly regarding fire safety and structural integrity. In 2005, a routine inspection revealed multiple violations related to fire safety, egress obstruction, and combustible storage, though these were all abated by November 2006.

A similar routine inspection in 2000 and a complaint about unsafe stairs in 1995 were also resolved. The most recent building-related complaint was filed in 2014 regarding alterations to the passageway between the rear yard unit and garage, which was marked as not active. Recent maintenance issues have primarily involved exterior cleaning concerns, with multiple 311 calls in 2024 regarding garbage and debris, though these are street-related issues rather than building-specific problems. The property has demonstrated a pattern of addressing both routine maintenance and significant structural improvements, with all recorded building permits showing either completed or properly filed status, suggesting responsible management of the property's maintenance needs.
