491-497 4th Ave, San Francisco, CA 94118

The property at 491-497 4th Avenue in San Francisco's Inner Richmond district is a two-story, four-unit multi-family residential building constructed in 1922 and currently owned by San Francisco Bay Area Prop. The building has undergone several significant renovations over the past few decades, with the most recent major work attempted in 2020 involving a comprehensive window replacement project valued at $35,000, though this permit was ultimately cancelled. Prior improvements include a complete kitchen and bathroom remodel in unit #493 in 2020 (successfully completed), and earlier renovations in 2008-2009 to unit #497 that included painting, tiling, window sash replacement, hardware updates, and hardwood floor refinishing.

The building experienced multiple building violations in 2001-2002, primarily related to security and fire safety requirements, including issues with door hardware, egress obstructions, and fire extinguisher maintenance, all of which were abated by April 2002. There were also complaints about unauthorized basement cabinet-making businesses in 2002, which were promptly resolved. More recent building-related issues have been minimal, with only routine complaints filed in 2006 and 2011.

The property's maintenance record shows regular upkeep, with older records indicating roofing and siding work in the early 1990s, though these permits have since expired. Recent activity at the property shows minimal building-related issues, though there have been multiple 311 calls in 2024 regarding parking enforcement, sidewalk maintenance, and garbage removal. The most significant recent concern is an open sidewalk defect report from July 2024 involving tree root damage. The property's most recent approved improvement, as per planning records, involves the installation of new wood windows with specified features, though no cladding of any type was approved for these windows.
