1359 48th Ave, San Francisco, CA 94122

The two-unit multi-family residential building at 1359 48th Avenue in the Outer Sunset, owned by Katherine Ann Fontaine, has undergone significant renovations and improvements since its construction in 1947. The most substantial recent improvement was completed in 2014-2015, when a ground-level unit was added with a complete kitchen and bathroom, along with necessary electrical and plumbing upgrades including a new boiler installation, DWV rough-ins, and a 200-amp electrical system upgrade with two meter sockets.

The property has received consistent maintenance attention, including a reroofing project in 2020 costing $10,000, and multiple window replacements in 2014 involving wood sashes at both the front and rear of the building. Prior infrastructure improvements included the replacement of galvanized main water lines in 2014 and a complete electrical rewiring project that same year, which replaced old K&T wiring and updated lighting and receptacle systems throughout the building's various areas. The building has a history of maintaining compliance with housing regulations, with only one historical complaint from 1996 regarding an allegedly illegal unit, which was promptly investigated and abated within a week.

Recent external issues have been minor and primarily related to public spaces, including sidewalk parking violations and street tree maintenance matters, which were addressed by city services. The property has demonstrated regular upkeep and modernization efforts, with permits showing investment in both unit improvement and building systems infrastructure, suggesting proactive management of the property's maintenance and regulatory requirements. The most recent building inspections and permits indicate no current active violations or major structural concerns.
