Augrented Insights Report for 637A Vanderbilt Avenue

The two-family brownstone at 637A Vanderbilt Avenue in Prospect Heights, owned by John Vandecker, is an 1872 three-story building that has experienced some notable health and safety concerns in recent years. Most prominently, there is an active violation as of September 2024 regarding the failure to file the 2023 External Low-Pressure Inspection, which remains unresolved.

The building has a concerning pattern of rodent activity, with the most recent inspection in May 2025 passing, but showing a history of rat activity in previous inspections throughout 2023. The Department of Health and Mental Hygiene (DOHMH) records show multiple food establishment complaints, including a 2024 complaint about rodents/insects/garbage, and several letter grading issues between 2020-2022, though these have all been closed or administratively resolved.

Positive indicators for the property include a clean bedbug report history over the past four reporting periods from 2020 through 2023, with no infestations, eradications, or re-infestations documented. While the recent rodent inspection results from 2024 and 2025 are passing, the pattern of past violations and rodent activity suggests ongoing monitoring of pest control efforts is warranted. The building has been consistently registered as a two-family house under Building Class 2, and has maintained its original three-story structure since construction.
