631-633 7th Ave, San Francisco, CA 94118

The three-story multi-family residential building at 631-633 7th Avenue in San Francisco's Inner Richmond district, owned by Ma Family Trust, was completed in 2001 as a two-unit structure, though historical records show an attempt to construct a four-story building in 1997 that was ultimately cancelled. The property has undergone several significant modifications and faced regulatory challenges over the years, most notably a 2015 complaint regarding a suspected illegal unit that prompted attempts to legalize a ground floor dwelling unit and revert unauthorized second floor modifications, including the removal of a wet bar and non-permitted partition walls. This 2015 work was eventually cancelled, leaving an active complaint status.

More recently, in 2024, repairs were initiated to address dry rot siding issues on the back building, with permits issued for replacement of up to 60 square feet of siding and an exterior door. The building's history includes two fire safety complaints in June 2010 related to combustible materials, though these were marked as corrected the same day. The property has generated multiple maintenance and regulatory issues over the years, including three separate illegal postings incidents in 2022-2023, and various parking violations on surrounding streets, with several citations issued for driveway blocking.

The building's permit history shows various modifications and attempts to rectify unauthorized improvements, including a 2015-2016 period of work valued at $60,000 related to compliance with housing regulations, though this permit was ultimately cancelled. A 2024 permit for dry rot repairs suggests ongoing maintenance attention to building exterior issues. The property's permit and complaint history indicates a pattern of unauthorized modifications and subsequent attempts at compliance, with the most significant and unresolved issue being the suspected illegal unit complaint from 2015.
