747-749 Capp St, San Francisco, CA 94110

The property at 747-749 Capp Street is a two-unit multi-family residential building located in San Francisco's Inner Mission neighborhood, constructed in 1900 and classified as a Flats & Duplex structure. The building has undergone several significant modifications and improvements over the years, with the most recent major issue being a pending investigation into an unauthorized dwelling unit that was reported as a neighborhood concern in April 2019 and is currently under review.

This situation has historical context, as the owner initiated legalization efforts in 2017 under the ADU ordinance, and there was a previous complaint in 2016 regarding possible short-term rental activity. Other notable improvements include a completed solar panel installation in 2003 (both electrical and roofing work), a completed sewer line replacement in 2014, and various renovations in the late 1980s and early 1990s, including kitchen and bathroom remodels, plumbing and electrical upgrades, and restoration of original ceiling height.

The building has experienced some infrastructure issues, including a sewage backup incident in 2013, and there have been multiple 311 calls regarding street cleaning matters in 2016. Recent records from 2024 indicate issues with human waste on the property and driveway blocking incidents, though these are primarily external concerns not directly related to the building's condition. The property's maintenance history shows attention to systems upgrades and compliance issues, with most permits having been successfully completed or resolved, though some older permits from the 1990s are listed as expired or cancelled.
