161-163 San Carlos St, San Francisco, CA 94110

The two-unit residential building at 161-163 San Carlos Street in the Inner Mission, owned by Brian A. Delbove, is a one-story flats and duplex structure built in 1906. The property has undergone several significant modifications over the years, with the most notable change occurring in 2009 when permits were issued to convert the two-unit building into a three-unit structure.

This conversion included removing the staircase that connected the upstairs and downstairs units and adding a kitchen to the downstairs unit, though the project was completed with a reported cost of $15,800. Earlier modifications included a kitchen and bathroom remodel in 2004, though this permit expired, and the removal of a bedroom and kitchen from the ground floor in 1989 was completed. In recent months (2024-2025), there has been a pattern of street cleaning issues in the vicinity of the building, with multiple reports (seven in total) regarding garbage and debris, including instances of yard waste and other loose materials.

There have also been three documented cases of sidewalk parking violations in late 2024, all resulting in citations. Additionally, a basement unit (designated as 163A) was found to have operated as an unauthorized Airbnb rental from fall 2013, though this investigation was ultimately closed with no violation found. The building has experienced one documented fire incident, though it was minor and related to a malfunctioning alarm system with no civilian injuries reported.
