1446-1448 9th Ave, San Francisco, CA 94122

The two-unit residential building at 1446-1448 9th Avenue in the Inner Sunset, owned by the Delorenzi Family Trust, has undergone several significant maintenance and safety-related events since its construction in 1909. Most recently, in February 2023, the building received a substantial roof renovation costing $19,200, which involved complete removal of existing roofing materials and installation of new shingles and a modified bitumen system.

The electrical system was notably upgraded in 2003 with an underground service conversion and 200-amp main service upgrade. The building has experienced several safety inspections and maintenance issues over the years, including three separate building violations in 2002 related to staircase repairs, and 2010 violations concerning fire safety equipment and handrails, though all these issues were abated within reasonable time frames. There have been multiple concerning incidents regarding unauthorized units in the building, with investigations in 2012-2013 suggesting the presence of unauthorized units with separate utilities and questionable access routes.

A notable infrastructure issue occurred in 2013 with a flood incident reported in one of the apartments. While the building's documented history shows these violations and complaints were addressed and resolved, including a 1986 permit to bring the building into code compliance, the property has experienced recurring issues with parking enforcement, with multiple citations for blocked driveways recorded between 2021 and 2024. The building's maintenance record, particularly the recent roof renovation and electrical upgrades, suggests active property management, though the historical pattern of building violations regarding safety features and unauthorized units indicates past maintenance challenges that required remediation.
