126-128 5th Ave, San Francisco, CA 94118

The Yim Family Trust owns this two-unit, two-story multi-family residential building located at 126-128 5th Avenue in the Lake - Presidio neighborhood. Built in 1910, this flats/duplex property underwent significant renovations in the mid-2000s, most notably a $360,000 expansion project completed in 2004 that added a substantial rear addition with two bedrooms per floor, a master bedroom behind the garage, and a penthouse, while raising the building 2.5 feet to accommodate a four-car parking garage.

During the renovation period, there were multiple building complaints filed in October 2006 claiming unauthorized work beyond the scope of the permits, including concerns about a fourth-floor addition blocking views, though these complaints were subsequently abated within days. The building has undergone several important safety improvements, including the installation of a fire sprinkler system in 2006 ($20,000) and comprehensive electrical upgrades in 2006 that included installing three meters and panels, and wiring for 50 lights and 70 receptacles.

Recent activity at the property has been minimal, with only routine maintenance and minor issues reported through 311 calls, such as parking violations in 2022 (one of which resulted in a citation) and some environmental health and sign maintenance matters in previous years. The only documented fire incident was a false alarm in 2007 due to a malfunctioning system, and no civilian injuries have ever been reported. The most recent building permit on record is from 2007 for street space usage, with no significant construction or major repairs documented in the past decade, suggesting the property has maintained its improvements from the mid-2000s.
