3276-3280 20th St, San Francisco, CA 94110
The three-unit multi-family residential building located at 3276-3280 20th Street in the Inner Mission, owned by Zaven S & Joan M Ayanian Trust, is a three-story flats and duplex structure built in 1909. The property has seen several significant maintenance and improvement works over the years, with the most recent substantial renovation being an ongoing unit upgrade as of January 2025, including kitchen cabinet replacement, bathroom remodeling, and flooring improvements at a cost of nearly $39,000.
The building has undergone essential plumbing work, with a completed sewer and house trap replacement in December 2024, following a previous sewer line upgrade in 2012. The property's historical records show routine housing inspections in 1999 and 2008, both of which were completed without noting any persistent concerns. A notable fire hazard violation was recorded and resolved in June 2006.
Recent service calls from early 2024 indicate ongoing challenges with street parking issues, particularly regarding driveway blockages, with multiple citations issued to offending vehicles. There have also been recurring reports of garbage and debris on the property grounds in 2024, though these were addressed promptly by city services. While the building's structural and plumbing systems appear to be receiving regular maintenance, as evidenced by the recent permits and completed works, the frequency of illegal parking incidents and occasional street cleaning issues suggests continued attention to the surrounding area management may be necessary.
