431 31st Ave, San Francisco, CA 94121

The property at 431 31st Avenue in the Central Richmond neighborhood is a three-story, two-unit multi-family residential building constructed in 1991, currently owned by the Ng Family Trust. The building underwent significant construction activity in 1990, including the installation of a partial sprinkler system and a complete sprinkler system, following the demolition of a previous two-family dwelling on the site. Prior to the new construction, in 1987, the original building faced several structural challenges, including termite damage, dry rot issues requiring foundation and exterior wall replacement, and the relocation of non-structural walls on multiple floors.

One notable building complaint from July 2019 involved ADA compliance issues in the common areas, including inaccessible garden doors and heavy laundry room doors, particularly impacting senior and disabled residents. The building has experienced persistent parking-related issues in recent years, with multiple 311 calls between 2020 and 2022 regarding vehicles blocking driveways and parking violations, though these are not directly related to building conditions. The property's permitted work history shows substantial attention to safety features, particularly during its 1990 reconstruction phase with multiple sprinkler system installations.

In 2008, there was a fire complaint that was determined to have no merit. The building's recent history suggests ongoing challenges with common area accessibility and maintenance, particularly concerning ADA compliance, though this complaint was marked as not active with no clear resolution noted in the provided data. The consistent pattern of parking enforcement calls around the property between 2020 and 2022 indicates an ongoing issue with street accessibility, though this appears to be an external neighborhood concern rather than a building-specific problem.
