4234-4236 Mission St, San Francisco, CA 94112

The two-unit, two-story multi-family residential building at 4234-4236 Mission Street, constructed in 1933, has experienced several significant maintenance and safety issues over the past decade, with the most critical events occurring between 2017-2018. During this period, the property faced multiple housing violations including rodent infestation, security concerns related to windows and doors, plumbing issues, and problems with smoke and carbon monoxide detectors, all of which were abated by September 2017.

The building underwent multiple repairs and improvements, including a bathroom renovation in 2018 that involved window replacement, flooring updates, and installation of ADA signage, though there were initial concerns about the lack of proper permits for interior work. Electrical safety was addressed through several permits, with work completed in 2014 to correct various electrical code violations including emergency lighting, stage lights, and GFCI installations. The property has had four documented fire department responses between 2017-2018, all related to smoke detector activations with no fires or injuries reported.

Historical records indicate various maintenance work over the years, including sidewalk repairs, roofing in 1995, front glass repairs in 1985, and more recent plumbing work in 2013. The building had some structural concerns in 2010 regarding rear stairs that required repair, and there were issues related to an electric sign installation in 2017 that prompted code enforcement action. More recent activity at the property includes several 311 calls between 2021-2024, primarily related to parking enforcement and street maintenance, though these are not directly related to building conditions or safety.
