Augrented Insights Report

The two-unit residential building at 420-422 Linden Street in Hayes Valley, owned by Ramakrishnan Satish and constructed in 1909, has undergone several significant modifications and experienced various incidents over the past several years. In 2017, the property underwent substantial renovations including the installation of washer and dryer units in bathrooms, conversion of bathtubs to showers, and stove replacements in both units, with the work being properly permitted at a cost of $20,000. During this renovation period, there was one documented building complaint regarding construction activities reportedly spilling onto the sidewalk in June 2017, though this complaint is currently listed as not active.

More recently, the building has been the subject of multiple public health and environmental concerns. In 2024 alone, there were four public health complaints filed with the Department of Public Health, including two environmental health requests and a food-borne illness complaint. The property has also experienced recurring issues with garbage and debris on the street and sidewalk, with multiple reports in 2024 (including instances of needles and abandoned garbage), though most of these cases were resolved by city services.

Additionally, there was one recorded building fire incident, classified as unintentional, though no civilian injuries were reported. A notable event in the building's history was a tenant buyout at 422 Linden Street in November 2016 for $39,757.13, involving one tenant. The most recent recorded complaints primarily relate to public health and sanitation issues rather than structural concerns, suggesting that while the building itself may be stable, there are ongoing challenges with maintenance of the surrounding environment and infrastructure.

2017-06-22 00:00:00+00:00NoneBuilding Inspection DivisionThis covers both 420 and 422 linden street --- these units are undergoing renovation and the crews have been regularly using the sidewalk for their activities. today they have a large power saw on a large stand completely blocking the sidewalk. their activities have been highly intrusive but taking over the sidewalk (obviously without permit) seems to be illegal use. i have a photo of their activities and am happy to share it. we'd like their activities routinely spilling out onto the sidewalk to cease. please follow up with me on this. thanks!
