89 Heather Ave, San Francisco, CA 94118

The three-story, 12-unit apartment building at 89 Heather Avenue, owned by the Demartini family, has undergone several significant safety and maintenance improvements since its construction in 1951. Most notably, the building completed a mandatory fire alarm replacement in 2022, including the installation of a new conventional fire alarm panel and LF horns in the units, to comply with current fire safety codes.

The building has also addressed seismic safety requirements through a completed soft-story retrofit in 2016, demonstrating compliance with San Francisco Building Code Chapter 34B. The property has benefited from consistent maintenance and upgrades over the years, including multiple window replacements for improved energy efficiency between 1995 and 2011 (all windows were double-pane with a U-factor of 0.30). Plumbing upgrades include the installation of new domestic hot water systems in 2008 and a furnace replacement in 2015.

Routine safety inspections by Housing Inspection Services in 2000, 2003, 2008, and 2012 have been completed without any noted ongoing concerns. While there have been some street-level issues reported through 311 calls, such as blocked sidewalks and waste on the street, these are typical urban maintenance matters and do not directly reflect on the building's condition or management. The building experienced two fire alarm system-related complaints (2006 and 2016) which were promptly corrected, and there was one incident involving a flammable liquid spill, but no civilian injuries were reported in any incidents.
