1518 Treat Ave, San Francisco, CA 94110

The two-unit, two-story multi-family residential building at 1518 Treat Avenue in Bernal Heights, owned by Zhao Yun Qing, was constructed in 1900 and has undergone several maintenance and improvement projects over the past few decades. The property has a documented history of various renovations, including bathroom remodeling work in 1998, window replacements and exterior siding work in 1999, and more recent painting and siding repairs in 2008, costing approximately $7,000.

Of particular note, there were two building complaints filed in November 2003 regarding unauthorized work involving curb cutting and concrete pouring for an illegal driveway, though one of these complaints was abated the following day, while the other remains listed as not active. The building's maintenance record indicates regular upkeep, with multiple reports of street cleaning and abandoned vehicles in the vicinity of the property between 2011 and 2023.

There were two instances of loose garbage requiring general cleaning in 2011 and 2022, and various street-related issues including a pavement defect in 2021 and a burnt-out streetlight in 2014 that were all resolved through proper channels. A 2011 environmental health service request was transferred to the Healthy Housing & Vector Control Program. While most of these incidents were external to the building itself, they provide context about the surrounding neighborhood environment.
