637-639 Masonic Ave, San Francisco, CA 94117

This two-unit residential building, located at 637-639 Masonic Avenue in the Park North neighborhood, is a two-story flats and duplex structure built in 1917, currently owned by Stdenny Steven & Semarapiki. The property has undergone several significant renovations in recent years, with the most substantial work occurring between 2016-2020. This included comprehensive bathroom and kitchen remodels in both units, with particular focus on unit 639 where a tub was replaced with a shower and new plumbing fixtures were added.

The electrical systems were also upgraded during these renovations, including a panel upgrade to 120 amps and installation of new circuits, lighting, and appliance connections. More recent work in 2020 involved a kitchen relocation project in the second floor unit, with associated electrical and plumbing work. The building's maintenance history shows attention to necessary repairs, including addressing dry rot issues in 2020 and retrofitting three windows in the rear sunroom in 2016.

The property has experienced some external issues in recent years, with multiple 311 calls recorded between 2023-2024 regarding graffiti, illegal parking, and sidewalk blockages, though most of these cases were resolved through normal channels. A notable incident is an open graffiti case from June 2024, described as "offensive" by DPW Ops Queue. The property's infrastructure appears to be well-maintained, with all major renovation permits marked as complete, though it's worth noting that the 1993 reroof permit has expired without any recent roof work on record.
