The property at 3654-3656 20th Street is a 6-unit, 3-story multi-family residential building constructed in 1907, currently owned by the Owyang Shirley Trust. The building has undergone significant safety improvements in recent years, including a mandatory soft-story retrofit completed in 2023 at a cost of $60,000. This work was carried out to comply with San Francisco Building Code requirements and involved the relocation of plywood shearwalls and concrete grade beams.

Prior to this, the building had several maintenance and improvement projects including kitchen remodeling (2019) with associated plumbing and electrical work, window replacements (2009), and repair of dry rot in rear stairs (2009). The building's history includes several building violations and complaints, though all have been resolved. Notable past issues included staircase repairs, removal of egress obstructions, and water damage repairs between 2002 and 2009.

A recent complaint regarding failure to comply with the Tier III soft-story seismic retrofit program was filed in 2020 and resolved in 2023, indicating that all required seismic safety improvements have now been completed. The property has had regular maintenance and periodic inspections, with the most recent building permit work relating to final inspections of completed soft-story retrofit work. Recent 311 calls from 2020-2024 have primarily concerned street cleaning and sidewalk maintenance, with one open issue regarding tree root damage to the sidewalk from 2021. The building is now in full compliance with current safety standards, having completed all mandatory seismic improvements and obtained the necessary permits and inspections.
