1320 20th Ave, San Francisco, CA 94122

The two-story multi-family residential building located at 1320 20th Avenue in the Central Sunset neighborhood is a four-unit apartment complex built in 1958, currently owned by the Teresa Yee Revocable Trust. The building's maintenance history shows several significant improvements, including the replacement of four front windows with wood-clad windows in 2014 (completed) and reroofing work permitted in 2013 at a cost of $5,000.

A notable building violation from 2001 regarding a malfunctioning smoke detector was promptly addressed within a month. The property experienced some recent disturbance in November 2021 due to construction work generating complaints about excessive noise during early hours. The building's immediate surroundings have faced persistent issues with street cleaning and maintenance, as evidenced by numerous 311 calls between September 2024 and January 2025, with reports of various types of debris, including human waste, electronics, glass, and general garbage.

The property has also experienced some exterior maintenance challenges, with documented cases of graffiti on both the public sidewalk (October 2024) and building surface (September 2024), though these were not considered offensive. The building's earlier history includes a routine housing inspection in 2001 and another in 2014, with a completed action in 1984 to bring the building into code compliance. While the recent high volume of street cleaning calls suggests ongoing challenges with the immediate vicinity's cleanliness, these issues primarily relate to exterior conditions rather than the building's structural or safety systems.
