621 Natoma St, San Francisco, CA 94103
The two-unit residential building at 621 Natoma Street, owned by Matthew P. Leffers, has a storied history dating back to its 1906 construction. The property has experienced recurrent maintenance issues over the past two decades, with the most recent significant concern being documented flooding problems in early 2015, where one unit reportedly experienced five inches of water accumulation due to pipe issues during rainstorms. The building has undergone several major repairs, including termite remediation (1994) and reroofing work (1991), though some permits from this period are now expired.
A notable cluster of building violations emerged in October 2003, including problems with smoke detectors, toilet security, electrical wiring, light fixtures, and damage to interior surfaces, though these were all abated by December 2003. Additional violations were recorded in 2008 regarding fire safety and structural concerns, and there were complaints in 2004 about electrical issues and heating problems. The building's condition has raised multiple concerns over the years, as evidenced by various tenant complaints between 1996 and 2005. These issues included heating failures, plumbing problems, mold growth, and questions about building code compliance.
The property has also experienced recurring environmental challenges, with multiple reports of graffiti, debris, and sanitation issues noted in recent 311 calls throughout 2023-2024. While many historical violations have been resolved, the pattern of water-related issues in 2015 and the presence of maintenance violations in various categories suggest ongoing upkeep requirements. The building's maintenance history includes both addressed violations and some expired permits, indicating a complex relationship between repairs undertaken and regulatory compliance during the property's lifespan. Recent 311 calls primarily relate to exterior conditions, such as street cleaning and lighting issues, though these are more related to the surrounding area than the building's internal conditions.
