522-524 37th Ave, San Francisco, CA 94121

The property at 522-524 37th Avenue is a four-story, two-unit multi-family residential building located in San Francisco's Outer Richmond neighborhood. Built in 1906 and owned by Chris Lau and Dia Yim, this building has undergone significant renovation and construction work since 2015. Major improvements have included the installation of a residential elevator (in 2018), complete electrical systems for both units (2015), and extensive plumbing work including new duplex unit installations, kitchen and bathroom fixtures, and heating systems for both units (2015-2017).

The building's construction history is notable for a series of street space permits issued between 2016 and 2017, and a significant plumbing project in 2009 that included comprehensive updates to multiple bathrooms, kitchens, gas lines, and utility services. However, the building's history also includes several concerning incidents and ongoing violations, particularly during the 2007-2009 period. There are active violations related to excessive excavation work that occurred in 2008, creating potentially hazardous conditions at the property lines, with associated compliance issues. Additional complaints from that time period documented unsafe site conditions, including unsecured debris and safety hazards.

More recent complaints in 2017 raised concerns about construction debris blocking sidewalks and sand containment issues. The property has experienced recurring issues with sidewalk parking violations in recent years, particularly involving vehicles not adhering to parking regulations. While many of these historical issues have been resolved through subsequent permits and inspections, the property has required multiple permit renewals and inspections to complete various systems installations, suggesting a somewhat protracted construction timeline. Recent building improvement work appears to be largely complete, though some systems (such as the elevator) were permitted but either installed under an expired permit or not completed according to current records.
