1339 20th Ave, San Francisco, CA 94122

The property at 1339 20th Avenue is a two-unit, two-story multi-family residential building located in San Francisco's Central Sunset neighborhood. Built in 1924 and classified as a Flats & Duplex structure, the building has undergone several maintenance and improvement projects over the years. Most notably, in 2016, a $12,500 foam roof overlay was completed for both 1339 and 1341 20th Avenue, representing a significant roof maintenance upgrade. The building experienced a furnace change-out in early 2015, though records indicate this permit eventually expired.

The property has a documented history of maintenance issues and resident complaints, particularly regarding ventilation and weatherproofing. In July 2001, multiple violations were recorded regarding weatherproofing and siding repairs on the north side of the property, as well as exhaust fan termination issues; however, these violations were abated by September 2001. More recently, in February 2016, there was a complaint about mold in a back room of the house, though this complaint is listed as not active. The building's mechanical systems have required attention, including the aforementioned furnace replacement and roof work.

The surrounding area has experienced various maintenance and parking-related incidents, particularly in recent years. Between 2017 and 2021, there have been multiple reports of vehicles blocking driveways, with several cases resulting in citations. There were also two reports of abandoned vehicles in the vicinity in 2017, though in both cases, the vehicles were gone when authorities arrived. Additionally, there have been occasional sidewalk defect reports and graffiti issues in the immediate area, with the most recent being a closed graffiti case from March 2021. The overall pattern of complaints and incidents suggests that while the building has had its share of maintenance issues, many historical violations have been addressed, though attention to mechanical systems and weatherproofing has been necessary throughout its history.
