1139-1143 Lake St, San Francisco, CA 94118

The 3-unit, 4-story multi-family residential building at 1139-1143 Lake Street, owned by the Dusanic Family Trust and built in 1912 in the Lake - The Presidio neighborhood, has undergone significant safety and system upgrades in recent years. Most notably, in early 2019, comprehensive fire safety improvements were completed including the installation of a new fire sprinkler system on the 4th floor with 18 heads, a 2-inch underground fire service, and a fire alarm monitoring system. The building has also seen substantial infrastructure improvements, including roof work with framing repairs ($30,000) in early 2019, and the installation of a solar power system (6.555 kW) in 2016.

The property has experienced recurring issues with heat and maintenance systems, with several permits for heating system upgrades and replacements between 2009 and 2019. A notable complaint from 2009 regarding inadequate heating was filed and resolved in 2010. There was also a complaint in 2017 regarding unauthorized window size modifications on the east property line of the top floor, which remains active as of October 2023.

The building underwent routine housing inspections in 2001, 2008, and 2017, with multiple violations recorded in 2017 related to building safety requirements, including fire extinguisher provision and routine safety inspection access, though these violations were subsequently abated. Recent maintenance records show typical urban building issues such as graffiti removal, tree maintenance, and street cleaning, with the most recent service requests primarily related to street and sidewalk conditions. The building's systems have been regularly updated and maintained, with multiple permits showing proper documentation of work performed, though there are a few expired permits that may require follow-up for final inspections. The property has a documented history of compliance with housing codes, though some historical violations indicate past challenges with maintaining building safety standards, all of which were addressed through proper channels.
