Augrented Insights Report

The 5-unit, 3-story multi-family residential building at 491 30th Avenue in the Central Richmond neighborhood, owned by the S&p Ng Family Trust 2007, was constructed in 1979 and has undergone several significant maintenance and safety improvements over its lifespan. Most notably, the building completed a mandatory soft-story retrofit in 2015 (Tier 3), ensuring seismic safety compliance, and underwent roof replacement projects in 2011 and 1994. A ground floor room and bath were successfully legalized in 1991, and the building's meter size was adjusted in 1986.

The property has experienced periodic fire safety and building code compliance issues, with the most recent routine inspection in 2023 identifying several concerns that were subsequently addressed, including repairs to doors and removal of egress obstructions. Historical violations in 2004 related to fire safety, such as fire escape maintenance and combustible storage, were resolved within two months. A 2023 complaint regarding a rusty fire escape was recorded, though it is no longer active.

The building has maintained regular compliance with housing inspections, with all identified issues being addressed in a timely manner. While there have been numerous 311 calls regarding the surrounding area in 2023-2024, these primarily relate to parking enforcement and street maintenance rather than building-specific concerns. Currently, there are no active violations or open cases related to the building itself.
