Augrented Insights Report

The 7-unit, 4-story multi-family residential building at 274-284 Diamond Street, owned by the Kao 1999 Revocable Trust, has undergone several significant improvements since 2016. The most notable project was the construction of an accessory dwelling unit completed in 2016, which included mandatory soft-story seismic retrofitting. The building has seen substantial safety system upgrades, including the installation of a comprehensive sprinkler system in 2018 (with 19 sprinklers on the first floor and a dedicated 2" underground fire service), and a new sprinkler monitoring system with flow and supervisory capabilities.

Recent improvements include a $30,000 kitchen and bathroom remodel in 2019 that added washer and dryer facilities, along with electrical and plumbing upgrades. The building has experienced several maintenance and safety-related issues, particularly during 2019 when multiple complaints were filed regarding ventilation problems, construction dust containment, blocked fire extinguishers, and window repairs. All of these complaints were ultimately resolved between April and June 2019.

Historical records show the building faced multiple fire safety violations in 2001, including issues with combustible storage, fire extinguishers, and egress obstructions, though these were abated by July 2002. More recent infrastructure improvements include electrical system upgrades, with the installation of new electrical heaters and necessary updates to meet current code requirements. The property has maintained compliance with San Francisco's soft-story retrofit program, with work completed and a Certificate of Final Completion (CFC) issued.
