812 31st Ave, San Francisco, CA 94121

The property at 812 31st Avenue in the Central Richmond neighborhood is a three-story multi-family residential building constructed in 1981, containing two units and currently owned by Huie 1993 Trust The. The building's history reveals significant concerns about unauthorized modifications, most notably between 2002 and 2015 when two illegal units were constructed without permits - one in the garage and another in the penthouse, involving an unauthorized change of occupancy classification from R-3 to R-1.

This violation was ultimately abated in February 2015. The building underwent a legitimate restoration project in 2002 that included work on the basement family room, addition of a bar sink, and restoration of a third-floor social room, though this followed the notice of violation. Earlier records show an expired permit for reroofing work dating back to 1997.

More recently, between 2021 and 2024, there have been numerous 311 calls related to the property, primarily concerning street and sidewalk cleaning issues and parking matters. These recent incidents include reports of abandoned mattresses, illegal sidewalk parking, and driveway blocking, though most of these issues were promptly addressed by city services and marked as resolved. The property appears to have maintained a relatively low profile in terms of major violations or complaints since 2015, with the most recent building-related activities primarily focusing on routine street maintenance and parking enforcement matters rather than building code violations or significant structural concerns.
