55-57 Clayton St, San Francisco, CA 94117

The Yip Family Trust owns a 2-unit, 2-story multi-family residential building at 55-57 Clayton Street in Park North, constructed in 1925. The property has undergone several significant improvements over the years, with the most recent major work being the replacement of the main water service with 1" copper pipe completed in August 2023.

There are notable plumbing and electrical upgrades from 2012, including an electrical service panel upgrade to 200 amperes. A concerning history from 2006 revealed unauthorized modifications, including a third dwelling unit on the ground floor with an illegally installed bathroom and kitchen, which were eventually addressed between 2006-2010. Recent infrastructure issues have emerged in 2024, with two documented sewage back-up discharges from the side sewer vent in July and September.

The building's maintenance history shows regular updates, including re-roofing in 2013 ($7,600) and various interior improvements such as kitchen remodels and plumbing fixture replacements. There have been multiple parking-related incidents near the property and some sidewalk-related concerns, including a graffiti incident in 2015, though these are more related to street administration than building condition. The property's permit history suggests ongoing maintenance and upgrading of both units, including compliance work in response to building violations, though some earlier permits from the 1990s are now expired.
