527 27th Ave, San Francisco, CA 94121

The three-story, two-unit multi-family residential building at 527 27th Avenue in the Central Richmond neighborhood, owned by the Huang 2014 Family Trust, has undergone several significant renovations and maintenance work since its construction in 1915. Most recently, in July 2023, a major remodeling project was completed in Unit 527, involving kitchen relocation, bedroom conversion, bathroom addition, and structural modifications, with associated plumbing and electrical work totaling $75,000.

In November 2023, work was performed to address a building violation regarding unauthorized deck and stair construction in the rear yard, with the owner attempting to legalize a previously unpermitted 60-square-foot deck and stairs at a cost of $8,000. The building has experienced some maintenance challenges over the years, including historical issues with dry rot repairs in 2014, mildew remediation in 2005, and various infrastructure updates including a furnace replacement. The property has exhibited some concerning recent patterns, particularly in 2024, with multiple infrastructure-related incidents including sewer system issues (backups and leaks in September and October 2024) and ongoing concerns about tree root damage to the sidewalk (as of July 2024).

The building's permit history shows a pattern of unpermitted modifications being addressed through regularization processes, most notably the recent rear deck and stair situation. Historical improvements include significant renovation work in 1983 and various maintenance updates, though some older permits have expired without completion verification. The property has experienced typical urban neighborhood issues such as parking violations and street maintenance needs, as evidenced by multiple 311 calls, though these are not directly related to the building's condition or habitability.
