186-188 17th Ave, San Francisco, CA 94118

The two-unit residential building at 186-188 17th Avenue, owned by the Cheng Family Trust, is a two-story flats and duplex structure built in 1922 in the Lake The Presidio neighborhood. The property has undergone several significant renovations over the past three decades, with the most substantial being a ground-level addition completed in 1999 that included a bedroom, family room, and bathroom. Other notable improvements include a complete kitchen and bathroom remodel in 1995, kitchen cabinet and countertop replacement in 1992, and a horizontal and vertical extension with rear stairs rebuild in 1987.

In terms of recent maintenance, four replacement windows were installed in the rear of the house in 1996. The building's location has experienced multiple street-related incidents over the past five years, though none directly related to the building's condition or safety. These include several reports of abandoned vehicles (seven complaints between 2018-2020), three of which were resolved when the vehicles were no longer present.

Other street incidents included reports of human or animal waste (January 2021, closed due to insufficient information), an encampment cleanup (August 2020, area cleared), and a sidewalk parking complaint from February 2019 which was not validated by responding officers. A street cleaning sign repair request from October 2018 was successfully resolved. While these street-related issues may impact the immediate neighborhood environment, they appear to be typical urban challenges unrelated to the building's structure or management.
