151 Arkansas St, San Francisco, CA 94107

The two-unit multi-family residential building at 151 Arkansas Street in Potrero Hill is a two-story flats and duplex structure built in 1911, currently owned by David Joseph Raynor. The property has undergone several significant structural improvements over its lifetime, including foundation work in 1991 (installation of new foundation and threaded rod in epoxy), construction of a concrete retaining wall in 1987, and removal of a storage shed in 1986.

More recent maintenance work includes the replacement of the front door in 2017 and repairs to siding and rotting studs in 2018. In early 2018, the building experienced some notable issues, including complaints about missing siding on the south side allowing water and pest intrusion, concerns about a potentially unsafe staircase with a cracked concrete archway, and violations related to exposed plumbing piping near the property line. These plumbing issues were resolved by March 2018 with proper rerouting of vent lines.

The building has also experienced some infrastructural challenges since 2024, with records showing flooding and debris concerns, though these recent issues appear to have been addressed. Notably, there were earlier fire safety violations recorded in 2005-2006 at a different address (1450 Mariposa Street) related to construction without permits and improper storage of flammable materials, though these were corrected promptly. The property's maintenance history suggests regular upkeep, with the most recent building permit work addressing structural elements complete by 2018.
