638 Moraga St, San Francisco, CA 94122

The two-unit residential building at 638 Moraga Street in the Inner Sunset, owned by the Bertha M T Ouyang Trust, is a 1940s flats and duplex structure that has undergone several significant maintenance and improvement projects over the years. Most recently, in September 2023, a violation was issued regarding building contact information, though this was subsequently abated. The property has a history of addressing structural issues, including repairs to wooden siding in 2015, dry rot remediation in 2009, reroofing in 2007, and the installation of aluminum windows in 1992.

A notable plumbing upgrade occurred in 2012 with the replacement of the house trap. The building's outdoor area has experienced multiple tree-related issues, with the most recent incidents in 2024 involving an overgrown tree and a general request for urban forestry services. Between 2018 and 2020, there were several reports of damaged trees, fallen trees, and pruning requests, all of which were resolved.

The property has also faced some aesthetic challenges, including sidewalk graffiti in 2019, which was promptly addressed. Three fire-related complaints have been recorded, with the most recent in 2023 resulting in a violation for building contact information, though the property has generally maintained compliance with necessary corrections in previous incidents. The building's maintenance record shows regular attention to both structural and exterior upkeep, with most historical permits indicating proper completion of work.
