552 Arlington St, San Francisco, CA 94131

The two-unit residential building at 552 Arlington Street in the Glen Park neighborhood, owned by W P Morris Tr, is a two-story flats and duplex structure built in 1906. The property has undergone several significant infrastructure improvements over the past decades, with particular attention to retaining wall and sewer system maintenance between 2011 and 2013, including multiple permits for rebuilding retaining walls and sewer connections, with costs ranging from $2,500 to $25,000.

More recent maintenance includes the installation of two water heaters in August 2024, though this work initially led to a housing complaint about unpermitted installation and potential mold issues, which was abated by late August 2024. The building has a history of plumbing and infrastructure upgrades, including a roofing project in 2004 and various drainage work, though some permits have expired without completion. The surrounding area has experienced various maintenance and service issues in recent years, including tree-related concerns (overgrown and damaged trees), sidewalk blockage, and street defects, with the most recent being a hanging limb issue reported in October 2024.

A minor fire incident involving a carbon monoxide detector activation occurred, though no actual carbon monoxide was present and no civilian injuries were reported. The property management has generally addressed building code violations and maintenance issues, as evidenced by the relatively recent resolution of the plumbing permit complaint. The building's permit history suggests ongoing attention to structural and plumbing systems, particularly focusing on water-related infrastructure and exterior elements such as retaining walls and landscaping.
