1834-1838 Mason St, San Francisco, CA 94133

The 6-unit, 4-story multi-family residential building at 1834-1838 Mason Street in North Beach, owned by David & Elizabeth Jensen, was built in 1909 and has undergone several significant renovations over the past decade. Most recently, in October 2023, the building completed a bathroom remodel including new fixtures, lighting, and associated plumbing work costing $20,500. In July 2023, backflow prevention devices were installed and tested, and in 2022, insulation and drywall improvements were made.

A major renovation occurred between 2013-2014 when the building received comprehensive upgrades, including the installation of a new fire sprinkler system, complete electrical rewiring with a new 400-amp panel, and extensive plumbing work for new bathrooms and kitchens throughout the building. The building's history includes some concerning events between 2012-2016, with violations and complaints regarding unauthorized work and permit issues, particularly related to a roof deck construction that allegedly raised the building by 2 feet. There were also multiple building complaints during 2013-2014 regarding construction noise, debris management, and allegedly unauthorized modifications to historical windows.

These issues appear to have been resolved, with most permits from that period having been finalized. The property has undergone regular maintenance and inspection, including recent work to address fire safety systems and plumbing infrastructure. Recent activity has focused on routine improvements rather than emergency repairs or major structural changes, suggesting better compliance with building regulations.
