3277-3279 20th St, San Francisco, CA 94110

The two-unit residential building at 3277-3279 20th Street in San Francisco's Inner Mission is a two-story flats and duplex structure built in 1906, currently owned by Rex and Carol Wood. The building's maintenance record shows a single permitted improvement - a $6,300 reroofing project completed in July 2007.

The property has experienced significant street and sidewalk cleaning issues in recent years, particularly in 2024-2025, with multiple reports of garbage and debris, though most of these cases were resolved without requiring further action. There have been two documented encampment-related incidents near the property (October 2022 and August 2024), and a notable instance of human or animal waste near the property in April 2023, which was determined to be on private property rather than the public sidewalk.

The building's vicinity has faced several infrastructure and public space challenges, including a flooding/sewer issue on the street reported in August 2022, and questions around shared spaces and health violations that were ultimately determined not to be related to the building itself. In 2022, there were two separate investigations regarding shared spaces - one related to a violation at the roadway and another involving a child request regarding trash and waste management, though both cases were either abated or not directly related to the property. While the building itself may not have experienced any direct issues requiring intervention, the surrounding area has faced persistent challenges with public space maintenance and infrastructure, as evidenced by multiple 311 calls over recent years.
