3847 22nd St, San Francisco, CA 94114

The three-story, multi-family residential building at 3847 22nd Street in Noe Valley, owned by Ralph Thuler, was constructed in 1906 and consists of two units. The property underwent significant renovations and improvements between 2012 and 2016, including a major project in 2012 that added a garden-level family room, studio, and roof deck, while preserving the historic street facade. In late 2015, the first floor was converted to create an accessory dwelling unit, which included the installation of a fire sprinkler system, radiant heating, and various other improvements.

The building experienced some serious issues in 2002-2004, with complaints regarding structural problems including leaning and sewer leaks affecting the foundation, though these were eventually resolved. A Notice of Violation in 2004 regarding unpermitted stair construction led to abatement in 2012. More recent improvements, including electrical upgrades and bathroom renovations, were completed in compliance with all necessary permits.

The property has had several infrastructure-related permits and improvements over the years, including multiple tree removals and maintenance operations in the vicinity. Recent 311 calls from 2022-2024 primarily relate to parking violations and tree maintenance issues rather than building concerns, suggesting the property is currently stable. The building's comprehensive renovation history shows significant investment in upgrading safety systems, including fire sprinklers, radiant heating, and electrical systems, indicating ongoing maintenance and improvement of the property. All recent permits and improvements appear to have been completed successfully, with the most recent significant work involving final plumbing inspections in 2017 and tree removals in 2023.
