1254 21st Ave, San Francisco, CA 94122

The property at 1254 21st Avenue in the Central Sunset neighborhood is a three-story multi-family residential building containing two units, constructed in 1990. The building's permitted improvements include an initial sprinkler installation in 1990, a street space permit in 2008, and most recently, a furnace replacement work initiated in December 2023, though this permit has expired without apparent completion confirmation.

The building has a troubling history of complaints between 2012-2013, with residents reporting serious maintenance and safety concerns including a lack of heat, presence of mold, inadequate security, missing smoke and carbon monoxide detectors, broken windows, poor sanitation, and evidence of overcrowding, though these complaints were marked as "Not Active" in the Housing Inspection Services system. Two 311 calls were logged in 2022 regarding street-related issues near the property - one concerning hazardous materials (though nothing was found upon inspection) and another about a damaged transit shelter platform, which followed standard resolution processes.

The building's permit history shows completed work for vertical and horizontal additions in 1988, but there are no documented permits for any substantial renovations or updates since the furnace work in late 2023. Given the age of the building and its reported maintenance issues from a decade ago, it would be prudent for prospective residents to conduct thorough personal evaluations of the current building condition and management practices.
