433-435 Baker St, San Francisco, CA 94117

The 433-435 Baker Street property is a two-unit, two-story multi-family residential building constructed in 1900, currently owned by Howe 2016 Family Trust. The building has undergone significant renovations and has a complex permit history spanning several years, with particular focus on fire safety systems, heating improvements, and unit modifications. Most notably, between 2017-2022, the property received substantial fire safety upgrades including the installation of a sprinkler monitoring system ($4,900 in 2022), smoke detection systems, and associated electrical work.

The building's heating system was modernized with the installation of a hydronic radiant heating system in December 2017, while plumbing upgrades included the addition of a fireplace in 2021-2023. The building's renovation history includes several concerning incidents, particularly in 2017-2020 when multiple complaints were filed regarding unauthorized work, including significant excavation and construction beyond permit scope. A notable complaint in September 2020 reported that construction remained unfinished for over two years, with active scaffolding and work resuming without proper permits.

Earlier complaints in 2015 documented possible unauthorized unit conversions and illegal unit status. Recent planning records indicate proposed foundation upgrades to current seismic codes and interior remodeling work, with attention to maintaining proper bedroom counts and open space requirements. The property has also experienced some exterior maintenance issues, as evidenced by multiple 311 calls in 2024 regarding garbage and debris removal, though these are primarily related to public space maintenance rather than building-specific issues.
