90 Heather Ave, San Francisco, CA 94118

90 Heather Avenue is a 20-unit, 3-story multi-family residential building constructed in 1951 and currently owned by the Toremi 1994 Revoc Trust. The property has undergone several significant structural improvements in recent years, including completion of a soft-story retrofit in 2015 ($78,000) and comprehensive window and door replacements that same year ($20,000). The building has a documented history of maintenance challenges, particularly regarding water-related issues including a notable 2016 complaint about water leaks with potential mold concerns, and recurring boiler permit violations between 2016-2017.

The property has faced multiple fire safety concerns, with open violations regarding sleeping area requirements (December 2023) and a historical pattern of sprinkler and alarm system issues that have generally been resolved promptly upon inspection. Regular electrical system upgrades have been performed, including the replacement of 18 sub-panels in 2003, suggesting ongoing attention to infrastructure improvements. The building's maintenance history reveals two main areas of recurring concern: water-related issues (including leaks and dry rot repairs) and periodic fire safety compliance matters.

While many historical violations and complaints have been addressed, recent fire safety issues including the open sleeping area violation from December 2023 indicate ongoing regulatory compliance challenges. The most recent building improvement work completed was related to window and door upgrades in 2015, and the property successfully completed its mandatory soft-story retrofit under San Francisco regulations. Regular maintenance appears to be ongoing, though the property has experienced periodic issues with its heating system and boiler permit compliance over the years.
