949-951 York St, San Francisco, CA 94110

The property at 949-951 York Street is a two-unit, two-story multi-family residential building located in San Francisco's Inner Mission neighborhood. Built in 1900 and currently owned by the Nancy A Chieng Trust, this flats and duplex structure has undergone several documented improvements and faced various maintenance challenges over the years.

The building received significant repairs in 2004 when a curb cut was legalized (with one permit being cancelled) and experienced a complete reroofing project in 2002 costing $9,000. Several concerning issues have been reported over the years, with the most significant being a complaint filed in July 2017 regarding unauthorized construction work involving a "significant rear expansion." Previous maintenance problems were documented in 2014, including issues with graffiti, broken windows, and unmaintained trees, while a housing inspection in 1995 temporarily addressed a concern about an illegal unit.

The property has experienced recurring issues with street maintenance and parking violations in recent years, with multiple 311 calls between 2021 and 2024 reporting loose garbage on the street and sidewalk, and three documented cases of driveway blocking. Most recently, there were two street cleaning incidents in October 2023 and minimal parking complaints in early 2024, suggesting some persistence of maintenance challenges in the immediate vicinity. The building's permit history shows reasonable upkeep through the years, with particular attention to roofing and access modifications, though the 2017 complaint regarding unpermitted work remains notable in terms of building compliance history.
