21 Clarence Pl, San Francisco, CA 94107

21 Clarence Place, a 6-story, 95-unit multi-family residential building constructed in 2012 and currently owned by Arc Light Co Affordable Lp, has experienced several significant maintenance and safety issues, particularly regarding its fire safety systems. Most notably, there is currently an active violation regarding the boiler permit (as of October 2024) and sleeping area requirements (as of December 2023), with recent violations in 2024 related to alarm systems, standpipe systems, and other fire safety concerns.

The building has undergone multiple plumbing system updates, including three boiler replacements between 2021 and 2024 (with the most recent in December 2024), though there appear to be ongoing permit compliance issues. The property has a history of various maintenance and safety concerns, including a significant incident in 2013 involving overflowing garbage and undesirable conditions in the garage. More recently, substantial street cleaning and waste management issues have been reported in January 2025, including multiple cases of overflowing city garbage cans and abandoned furniture.

The building's fire safety systems, while installed with various permits totaling tens of thousands of dollars, have shown persistent maintenance issues, as evidenced by multiple fire code violation citations throughout 2024. The building also experienced some tenant enforcement issues in 2023-2024, including violations related to illegal short-term rentals, though these were subsequently resolved. The property has a significant collection of building permits from 2012 to present, indicating ongoing maintenance and system upgrades, particularly in fire safety, HVAC, and plumbing systems, though many of these permits are marked as expired or indicate completed work that suggests historical permit compliance challenges.
