1031-1033 Guerrero St, San Francisco, CA 94110

The property at 1031-1033 Guerrero Street in Noe Valley is a two-unit, two-story multi-family residential building dating back to 1900, currently owned by Laurence & Esperanza Mahan. The building has undergone several significant changes and faced various compliance issues over the years.

Most notably, in 2007, there was a major intervention to remove an illegal kitchen and bathroom from the garage/basement area, with permits issued for the work across multiple trades including plumbing and electrical. In 2005-2006, the property experienced multiple housing code violations that required attention, including issues with electrical systems, interior surfaces (walls, ceilings, floors), windows, and plumbing fixtures, all of which were ultimately abated by November 2006. More recent history shows fence and trellis work being undertaken in 2020, though this was somewhat contentious as evidenced by a May 2020 complaint about construction noise during remote teaching hours.

There remains an active complaint from July 2014 regarding unpermitted construction in the garage area, which is particularly notable given the property's previous history with illegal units. While there were some permits filed in the early 1990s for seismic upgrades and garage work, these were ultimately cancelled. The most recent building-related activity appears to be limited to relatively minor exterior improvements, though the presence of unresolved complaints from 2014 raises some questions about full compliance with current building regulations.
