Augrented Insights Report

The two-unit residential building at 637 Lake Street, located in the Lake-The Presidio neighborhood, is a 2-story flats and duplex structure built in 1909, currently owned by Paual Siegel Separte Proper. The property has undergone several significant maintenance activities over the years, including two complete reroofing projects - one in 1999 and a more recent $18,950 project in 2017 due to roof leaks. In 2009, important plumbing work was completed to replace the house trap under the sidewalk.

The building has experienced some infrastructure challenges, including a sewer vent issue in October 2020 that was resolved by PUC Sewer Operations. The property has faced periodic exterior maintenance challenges, particularly in 2020 when multiple incidents were reported, including a sewage vent issue, a fallen tree, and instances of offensive graffiti. Historical records indicate some recurring issues with sidewalk blockage, particularly in March-April 2017 involving a residential totter, though these were noted for referral to DPT enforcement.

Two damaging tree incidents were recorded in 2014 and 2020, with the 2014 case being listed as a dead tree. The building's permit and violation history suggests regular maintenance but no major structural modifications or violations. The most recent significant event related to the address was a tenant buyout at the neighboring 639 Lake Street unit in July 2022, involving one tenant and a payment of $25,000.
