16-18 John St, San Francisco, CA 94133

The property at 16-18 John Street in Nob Hill is a two-unit, two-story multi-family residential building constructed in 1919, currently owned by the Ying Wong Revocable Trust. The building's history reveals significant modifications and compliance issues, most notably in 2008 when violations were documented regarding ground floor rooms occupied as habitable space without proper permits.

This led to a compliance order and subsequent renovation work costing $18,000 to remove an illegal kitchen and legalize bathroom and storage spaces, along with adding a laundry room. These improvements were accompanied by corresponding plumbing and electrical upgrades, including the installation of lights, switches, receptacles, and the electrical service conversion with a 150-amp main service upgrade completed in 2003. The building's maintenance record indicates periodic attention to external issues, with several 311 calls between 2014 and 2020 relating to graffiti removal and general cleaning needs around the property.

While there have been multiple reports concerning park structures and sidewalk maintenance in the vicinity, these were handled by appropriate city departments and were not directly related to the building's condition. The most recent documented issue was a graffiti incident on the residential portion of the building in January 2020, which was resolved. The property's documented history shows that most major compliance issues have been addressed, with no active building violations on record since 2008.
