424-428 Union St, San Francisco, CA 94133

The three-story multi-family residential building at 424-428 Union Street in Telegraph Hill, built in 1907 and containing 6 units, has experienced persistent maintenance challenges over the past two decades, particularly regarding its stairwell infrastructure. Most recently, in November 2023, dry rot repair work was completed on less than 50% of the second exit stair at the back of the building, which was not visible from the street. This followed a 2019 complaint about rotten floorboards and water-related issues in the stairway that required attention.

The building's maintenance history shows recurring issues with wood deterioration, as evidenced by a series of repairs including a $15,000 project in 2004 addressing stairs, deck, and window work in the back, and a $5,000 dry rot repair at rear stairs in 2001. Recent complaints raise some concerns about the building's maintenance practices. In October 2023, there was a report about elderly workers performing construction without proper safety gear or visible permits, though this complaint was marked as not active by November 2023.

More recently, in May 2024, a complaint was filed regarding wooden coverings on windows showing signs of deterioration on the building's side, with concerns about their potential to fall into a patio area. The building has also faced several regulatory challenges, with active interior surface violations from 2011 regarding damaged ceilings and reinspection access issues. While the property has undergone various maintenance and repair work over the years, these recurring issues suggest ongoing challenges with maintaining the building's structural components, particularly in terms of addressing moisture-related problems and ensuring proper safety protocols during maintenance activities.
