3763-3765 Clay St, San Francisco, CA 94118

This two-unit residential building located at 3763-3765 Clay Street in Presidio Heights is a two-story flats and duplex structure built in 1909, currently owned by the Barbara A Lawless Revocable Trust. The building has undergone several significant maintenance and repair projects over the years, with the most recent major work occurring in 2013 when both street space modifications and approximately 6 feet of sewer and house trap replacement were completed.

The property has a documented history of plumbing issues, particularly concerning the sewage system, with incidents recorded in 2019 suggesting ongoing infrastructure challenges, including a noteworthy incident in March 2019 involving an out-of-sewer-vent issue, and a previous sewage backup incident from 2014. Compliance and safety inspections have also been a focus, with records showing a failure to comply with a complete inspection in 1998, though this was eventually abated in 2001. The building's maintenance record shows various historical improvements, including a reroofing project from 1993, stairway repairs from 1986, and a significant building code compliance effort from 1987 that cost $1,750.

More recent external issues have included multiple instances of unauthorized postings (2012, 2022) and graffiti on street poles (2018), though these are primarily cosmetic and have been promptly addressed by city services. The plumbing system's age and history of maintenance interventions suggest this remains a critical infrastructure component requiring attention. While the building has experienced periodic plumbing and sewer system challenges, particularly evident in the past decade, most reported issues have been systematically addressed and resolved through appropriate city services and permits.
