AI summary · updated June 2026

821 Avenue N is a 4-unit, 3-story residential building in Midwood, built in 1931 and currently owned by David Malka. The property has experienced recurring pest control issues, with multiple documented rodent-related complaints and inspections between 2019 and 2024, including several failed inspections in 2024 (most recently in May 2024) and multiple instances of violations requiring follow-up inspections by the Department of Health and Mental Hygiene. The building is currently facing open violations from 2024 related to unsanitary conditions regarding garbage/recycling storage (Class B violation) and an outstanding issue regarding bedbug reporting non-compliance (Class A violation).

Additional concerning findings include an active Environmental Control Board violation from 2021 for failure to maintain a portion of the building (specifically noting disrepair of the side roof ceiling) with an associated penalty of $3,125. The building has a documented history of being reported as vacant, open, and unguarded at various times between 2021 and 2024, though inspections did not warrant violations at the time. Recent service requests in 2024 included complaints about unsanitary conditions that resulted in issued violations. The property has shown intermittent compliance with rodent control requirements, as evidenced by some passed inspections, though the pattern suggests ongoing challenges with maintaining proper sanitation standards. The building has also been subject to scrutiny regarding illegal conversion claims in 2023, though an inspector was unable to gain access to verify the conditions.
