1627-1629 9th Ave, San Francisco, CA 94122

The property at 1627-1629 9th Avenue is a two-unit, two-story multi-family residential building located in San Francisco's Inner Sunset neighborhood, originally constructed in 1900. In 2004, significant structural work was completed, including a horizontal addition at the rear, raising the building, and excavating a basement to create a four-car garage, with a reported cost of $441,500. The building underwent substantial improvements in the following years, including two separate plumbing projects in 2008 and 2007 involving bathroom and kitchen additions, along with installation of two furnaces and water heaters.

The electrical system was significantly upgraded in 2003 with an underground service conversion and 100-amp main service upgrade, followed by additional electrical work in 2007 involving extensive lighting and receptacle installations. More recently, there have been some concerning issues regarding the property's condition and management. As of July 2024, there is an open complaint regarding illegal construction and permit violations.

The property has experienced recurring issues with abandoned vehicles in the vicinity, with four separate incidents reported between 2016 and 2024, though all were resolved when vehicles were found to be gone upon inspection. The property and surrounding area have also faced some maintenance challenges, including reports of property damage in June 2024 (which was cancelled) and loose garbage issues reported in 2017 and 2018. Historical planning records show various proposals for the site, including attempts at a two-lot subdivision and partial demolition with construction of new single-family dwellings, though most of these proposals were withdrawn or otherwise closed without implementation.
