Augrented Insights Report for 421 Hawthorne Street

The two-family residence at 421 Hawthorne Street in Prospect-Lefferts Gardens is a two-story, three-unit building constructed in 1910, currently owned by Jennifer Maxwell.

The building's documented history shows minimal recorded incidents or inspections over the past several years, with the most notable being a successful rodent inspection conducted on December 21, 2018, which resulted in a passing grade.

Given the date of this inspection and the current date of July 2025, it is worth noting that there have been no documented rodent-related issues reported in the past seven years, though this should not be taken as an indication of current conditions. The relatively sparse history of recorded incidents or inspections could suggest either a well-maintained property or simply limited documentation of any issues that may have arisen.
