107-109 9th Ave, San Francisco, CA 94118

The two-unit, two-story multi-family residential building at 107-109 9th Avenue in the Lake-Presidio neighborhood, owned by Baron John F, has undergone several significant renovations since its construction in 1916. Most recently, in October 2024, the building experienced a sewage discharge incident from the side sewer vent, which was promptly addressed and resolved by the Public Utilities Commission - Sewer Operations.

In 2016, the property required maintenance work involving the repair and replacement of rotted sections in the lightwell staircase, an essential safety feature located mid-building and not visible from the street, with this $5,000 repair successfully completed. The building underwent substantial interior improvements in 2000, including complete kitchen upgrades with new plumbing and electrical work, sheetrock installation, cabinet and countertop replacement, flooring updates, and painting, with a budget of $8,500.

Earlier modifications to the structure included a horizontal addition completed in 1998, reflecting the building's ongoing adaptation to meet modern living standards. The property has experienced several parking-related issues in the vicinity, with three documented incidents between 2010-2020 involving vehicles improperly parked on sidewalks, though these incidents occurred outside the building itself and were resolved by parking enforcement authorities.
