789 Arguello Blvd, San Francisco, CA 94118

The two-unit, two-story residential building at 789 Arguello Blvd in the Inner Richmond, built in 1908, has undergone several significant infrastructure upgrades in recent years. Most notably, in August 2023, the property received a $24,000 reroofing project and underwent comprehensive plumbing improvements, including a shared sewer line replacement from the garage to the housetrap, installation of new housetraps, trench drains, and two floor drains. These recent improvements follow a pattern of systematic infrastructure maintenance, as evidenced by a gas line extension project completed in 2013.

The building's plumbing system has experienced challenges in the past, with documented sewage backup incidents in 1997 and more recently in March 2022, though the latter was resolved through PUC Sewer Operations intervention. The property has maintained active engagement with city services, with multiple 311 calls in 2024 regarding various neighborhood issues, including garbage, graffiti, and parking concerns. While most of these recent calls were not directly related to building-specific problems, they demonstrate regular interaction with city services.

A 2020 building inspection complaint was found to have no violations, and there was a historical issue in 2021 with illegal postings that was resolved. The property's most recent significant infrastructure work, including the sewer line and roofing updates, suggests proactive maintenance by current ownership. While there have been recurring plumbing issues in the building's history, recent permit activity indicates these systems are receiving necessary attention.
