3659-3677 20th St, San Francisco, CA 94110

The 20-unit, 2-story multi-family residential building at 3659-3677 20th Street, constructed in 1906, has undergone significant renovations and faced various maintenance challenges over recent years. Most notably, the building completed its mandatory Tier-3 soft-story retrofit in July 2024 at a cost of $45,000, demonstrating compliance with seismic safety requirements. Recent improvements include a reroofing project initiated in April 2024 ($36,973), and substantial interior work in 2021-2022 involving the creation of three ADUs in the ground floor parking area ($230,345).

The building has a history of unit upgrades, with multiple renovations between 2013-2020 involving kitchen and bathroom remodels, electrical upgrades, and plumbing improvements across several units. The property has experienced several tenant-related issues that required attention, including multiple instances of mold (2016-2017), a rodent infestation (2014), and various maintenance complaints. Fire safety has been a concern, with recent violations noted for sleeping area requirements (2023), though several fire-related complaints were found to have no merit.

The building's systems have been monitored through regular inspections, with recent fire inspections in 2023-2024 addressing sprinkler systems, alarm systems, and sleeping area requirements. Historical violations from 2002 regarding fire escape maintenance and fire extinguisher certification were resolved in 2017. In 2019, one tenant received a buyout of $30,000. While the building has faced various maintenance challenges over the years, recent improvements suggest active management and compliance with current building codes and safety requirements.
