490-496 2nd Ave, San Francisco, CA 94118

The property at 490-496 2nd Avenue in San Francisco's Inner Richmond district is a 2-story, 4-unit multi-family residential building constructed in 1922, currently owned by Shum & Sons LLC. The building has undergone several significant improvements over the past two decades, including the installation of 22 new wood windows in 2007 ($21,500), a complete roof replacement in 2004 ($6,000), and the repair of dry rot issues in the basement in 1987.

The property underwent periodic safety inspections between 1999 and 2017, with the most recent routine inspection in 2016 revealing multiple fire safety concerns that were subsequently addressed by May 2016, including the need for fire extinguisher servicing, stair repairs, and carbon monoxide alarm installations. A 2017 complaint noted potential lead paint concerns due to the building's age, though this was marked as "Not Active" on the same day it was filed.

Since October 2023, there have been several maintenance-related service requests, primarily regarding street cleaning, garbage, and parking issues near the property, with most being resolved promptly. A single EMS incident was recorded at the address, with no civilian injuries reported. The building's permit history shows regular maintenance and updates, particularly focusing on windows, roofing, and addressing structural issues as they arise, with no recent major renovations or violations on record.
