121-123 Precita Ave, San Francisco, CA 94110

The two-family residential building at 121-123 Precita Ave in Bernal Heights, owned by Ng Chind Yin Wong & Thomas, has undergone several significant modifications and faced various compliance issues since its construction in 1926. Most notably, in 2019, the rear perimeter underwent voluntary strengthening with plywood installation costing $24,000.

Major compliance actions occurred between 2012-2018, including the removal of unauthorized installations and conversion of illegal bedrooms at the first floor and basement, as well as a rear exterior staircase repair following a 2016 violation. The building's maintenance history shows attention to basic upkeep, including reroofing completed in 2016 ($9,000) and previous repairs to rear stairs in 1983.

The property has faced multiple building code violations primarily related to unauthorized modifications of an illegal ground floor unit with kitchen, bedrooms, and bathroom, which were addressed between 2012 and 2018 through proper permitting and conversions to storage space, accompanied by plumbing and electrical work. More recent activity consists of numerous parking enforcement calls between 2022 and 2024, with several complaints about blocked driveways and sidewalk parking, though most of these cases resulted in either citations or officers being unable to locate the offending vehicles. The building's record shows ongoing enforcement of parking regulations, with the most recent violation recorded in November 2024.
