739-741 40th Ave, San Francisco, CA 94121

The two-unit residential building at 739-741 40th Avenue in San Francisco's Outer Richmond neighborhood is a two-story flats and duplex structure built in 1947, currently owned by Chwang Ann. The building's maintenance history includes a reroofing project from 1998 (now expired) and the installation of six aluminum windows in 1988.

More recently, in 2010, both units received new 40-gallon water heaters, marking the most significant infrastructure upgrade in recent years. The property has experienced various neighborhood issues over the past several years, with the most notable being a tenant buyout at 739 40th Avenue in December 2019, involving two tenants and a payment of $60,000. There have been multiple parking-related incidents between 2020 and 2022, including several cases of driveway blocking and sidewalk parking, with varying enforcement outcomes.

The building's surrounding area has faced some infrastructure challenges, including pavement defects in early 2022, though these were resolved by March 2022. A noise complaint was filed in April 2020 regarding excessive noise, and there is currently an open case from December 2023 related to loose garbage on the street. The property management has maintained basic infrastructure through periodic updates, though the limited number of major improvements on record suggests a potentially aging building systems profile.
