631 8th Ave, San Francisco, CA 94118

The two-unit residential building at 631 8th Ave in San Francisco's Inner Richmond district is a two-story flats & duplex structure built in 1922, currently owned by Raymond Y. Wong and Roland Y. The building has undergone several significant maintenance and improvement projects over the past few decades, with the most recent being the $24,000 replacement of a deteriorated second exit stairway at the light court, completed in May 2024, which enhances the building's safety egress system.

Other notable improvements include a comprehensive electrical upgrade completed in 2005, involving the installation of lights, switches, receptacles, and circuits during kitchen and bathroom remodeling work. The building experienced a sewer-related incident in February 2022, including a sewage backup from a 4-inch vent, which was resolved by PUC Sewer Operations, though this may have temporarily affected resident comfort during the incident. The property has had recurring issues with street parking and abandoned vehicles in the vicinity, particularly between 2017 and 2019, with multiple reports of vehicles blocking driveways and abandoned vehicles, though most of these vehicles were gone by the time authorities arrived.

These parking issues appear to be more related to street management rather than building-specific concerns. A roofing permit from 1996 was recorded, though it has expired. The building's permit history suggests regular maintenance and updates to keep the property maintained, with no documented history of serious safety or structural issues beyond the noted sewer incident. The property has maintained compliance with safety regulations, as demonstrated by the recent stairway replacement project, though prospective tenants should note the building's age and the relative age of some of the systems compared to modern standards.
