3959-3961 Washington St, San Francisco, CA 94118

The three-story multi-family residential building at 3959-3961 Washington Street in Presidio Heights, owned by Lawrence & Nicole Blatt Lvg, is a century-old duplex that has undergone significant renovations and system upgrades in recent years. The most substantial improvements were completed between 2017 and 2018, including the installation of a comprehensive fire sprinkler system, new electrical systems with 300amp service, underfloor hydronic radiant heating, and extensive plumbing work involving multiple bathroom and kitchen installations. The building also received safety upgrades such as a sprinkler monitoring system and various structural improvements, including reconfigured rear exterior stairs, decks, and interior walls.

The property experienced some challenges during construction, including a May 2017 incident where chimney collapse occurred, reportedly affecting both the subject building and a neighboring property. However, this appears to have been addressed promptly. The building's infrastructure improvements included adding four direct vent fireplaces, seven bathroom renovations, and rooftop AC installation.

More recent maintenance issues have mainly involved external municipal services, with several requests for street cleaning, sewer service, and parking enforcement being recorded between 2021 and 2024. The building's most recent fire safety inspection in late 2020 noted issues with the sprinkler/standpipe systems, though these were corrected by early 2021. The property's comprehensive renovation history indicates significant investment in improving both safety systems and resident amenities over the past several years, though some permits from 2018 show as expired, which may require verification.
