Augrented Insights Report for 100 East 21st Street

The 84-unit, 6-story building at 100 East 21st Street in Flatbush, owned by Mark Neiman and constructed in 1941, has experienced several significant maintenance issues and code violations in recent years. Most notably, there is an active Environmental Control Board violation from June 2024 regarding the only elevator in the building, which affects numerous tenants including those with disabilities and carries a penalty of $3,125. In 2025, the building has faced multiple housing maintenance code complaints, including elevator maintenance issues, unsanitary garbage storage conditions, and a smoking/vaping violation.

There were also multiple complaints related to heat and hot water problems in March 2025, with some instances where HPD could not gain access to inspect the conditions. The building's maintenance history shows recurring problems with the elevator system, including multiple complaints between 2024-2025 about various elevator-related issues, with some violations still listed as active. There have also been significant concerns about sanitation, with violations related to garbage storage and pest control noted, particularly in 2024 when there was an infestation of both roaches and mice documented in apartment 103. Building systems have shown persistent issues, as evidenced by multiple housing maintenance code violations throughout 2024-2025, including problems with flooring, stairs, electrical systems, and various plumbing issues.

The building has a mixed history of compliance with rodent inspections, with some years showing rat activity while more recent inspections in 2025 returned different results. Prior violations from 2020 documented issues regarding unauthorized occupancy, including an illegal kitchen installation in the cellar, while a 2021 violation involved defective electrical wiring and outlet issues related to an electrical fire in apartment 216. The building has maintained a relatively good record regarding bedbug infestations in recent years, with no reported cases since 2021, though there was one documented case of mice and roaches in 2024. The property has also experienced some structural issues, including a March 2024 violation regarding a section of collapsed concrete ceiling in the parking garage.
