Initial analysis

The property at 4028-4030 24th Street in Noe Valley is a 3-story, 4-unit multi-family residential building with commercial space, built in 1907 and currently owned by Pedro Tan & Raquel B. The building has undergone several significant transformations, most notably converting a former massage establishment to a public bath house in 2013 and later to a small self-service restaurant in 2012 (Easy Breezy Yogurt Shop). A notable incident occurred in 2013 when fire damage required removal of debris and inspection of structural elements in the bar area. The building has faced multiple maintenance and compliance issues, including several violations in 2006 related to interior surfaces, electrical systems, and egress obstructions, as well as a 2019 violation regarding an unpermitted boiler. Recent building maintenance activities include water heater and HVAC upgrades, though there are persistent concerns about building upkeep as evidenced by recent 311 calls for cleaning, garbage, graffiti, and maintenance issues in 2024.

The property's historical records show a range of plumbing and electrical improvements, including an overhead service upgrade and extensive commercial space renovations in 2012. Several notable violations have been addressed over the years, including a 2001 complaint about unauthorized occupancy changes in the bar space, and a 2007 complaint regarding an improperly vented dryer. Recent infrastructure improvements include a water heater replacement in 2018 and various HVAC upgrades. The building's maintenance history shows attention to addressing code violations when they arise, with most being marked as not active or resolved. The most recent planning records show no active proposals for major modifications, though there was a disapproved request for a rear addition to the ground floor to expand the existing health spa. The building's current status shows active maintenance needs and periodic compliance checks, particularly regarding building systems such as the boiler and water heater.

Risk rating

How 4028-4030 24Th St's risk score is calculated
