1222-1224 3rd Ave, San Francisco, CA 94122

Located in San Francisco's Inner Sunset neighborhood, 1222-1224 3rd Avenue is a three-story, two-unit multi-family residential building constructed in 1947 and currently owned by Donald Cheng. The building has undergone several significant improvements over the past few decades, with the most recent major renovation occurring in September 2022 when both main water service supply pipes were replaced with 1-inch diameter copper pipes.

In 2018, the property received attention to its aesthetics and energy efficiency, with the installation of eight new windows in the back of the house featuring a low U-factor of 0.31. Earlier improvements include a substantial ground floor renovation completed in 2000, which added a bedroom, playroom/laundry room, and full bathroom, as well as a complete re-roofing project from 1989. The building's recent history has been relatively stable in terms of major building issues, though there have been some external incidents recorded through 311 calls.

Most notably, there was a noise complaint related to a major event venue in August 2024, and a parking enforcement call in May 2024 regarding sidewalk parking, though enforcement officers were unable to locate the offending vehicle. The property has been subject to typical urban challenges in recent years, including a reported encampment that was cleared in March 2021 and an abandoned vehicle report in October 2019, though in both cases, the issues were promptly addressed and resolved by city services. The building's maintenance record, particularly regarding water infrastructure (as evidenced by the 2022 plumbing permit), suggests ongoing attention to essential systems, while the 2018 window replacement indicates efforts towards improving the building's overall energy performance.
