4072 18th St, San Francisco, CA 94114

The three-story multi-family residential building at 4072 18th Street, owned by 4072 18th Street SF LLC, was constructed in 1901 and contains two residential units with ground floor commercial space. The property has undergone significant commercial space renovations in recent years, with the most recent permit issued in June 2024 for a $28,000 commercial remodel. There was a notable period of housing violations and complaints in early 2023, with the most serious issues involving heating problems, water damage, and safety concerns including non-compliant smoke/carbon monoxide detectors and fire extinguishers.

These violations were abated by February 10, 2023. The building has also experienced maintenance and safety issues involving the residential units, including reports of broken appliances and heating systems, most notably a dangerous unconnected furnace system discovered in July 2022. Recent infrastructure improvements include the installation of new smoke/carbon monoxide detectors in February 2023 and an electrical service upgrade to 400 amps in July 2018.

The property has active planning records indicating ongoing development and compliance work, particularly regarding the ground floor commercial space's change of use from retail to restaurant. There are two long-standing building complaints from 2019 and 2012 that remain active, involving unauthorized exterior work including new siding, trim installation, and window modifications, as well as concerns about construction work beyond permitted scope and an unpermitted rear structure installation. Recent maintenance issues have included two sewer backup incidents in early 2024 and various noise complaints related to the commercial space's operations. The building's commercial space has seen regular changes, with multiple permits issued between 2015 and 2024 for kitchen equipment installations, fire suppression system upgrades, and restroom modifications.
