Initial analysis

The three-story mixed-use building at 530-534 Irving Street in the Inner Sunset, constructed in 1907, contains three residential units and ground-floor commercial space, currently owned by Lam Quyen Duc. The building's history shows a pattern of ongoing maintenance and improvement, including significant work on the ground floor commercial space in recent years. In late 2020, there were violations related to unpermitted tenant improvements in the ground floor restaurant, specifically concerning electrical and plumbing work, though these were abated by February 2021. More recent building improvements include plumbing modifications in 2021 for gas lines and sink drains, and historical upgrades such as a 2003 underground service conversion to 400A 3-phase meters.

The property has experienced recurring issues with noise and disturbance, particularly regarding outdoor entertainment and amplified sound, with multiple 311 calls in 2022-2024 suggesting ongoing concerns with compliance and resident comfort. There have also been several historical commercial space modifications, including cooking equipment installations in 2014 and 2013, a fire suppression system installation in 2009, and various roofing and awning works in the early 1990s. The building has undergone multiple inspections and permits across various trades, including electrical, plumbing, and general building modifications, indicating active management and upkeep of both residential and commercial components. Recent complaints in 2024 regarding disruptive amplified sound and illegal parking suggest ongoing neighborhood impact issues, while planning records show successful referral processes for restaurant and ABC Type 41 licensing.

Risk rating

How 530-534 Irving St's risk score is calculated
