150 20th Street, Brooklyn, NY 11232

150 20th Street in Sunset Park, constructed in 2017 by Prospect Brothers Realty LLC, is a 6-story building that has experienced several notable issues since its completion. The most persistent and concerning current issues are four open Housing Maintenance Code violations from 2021 to 2024 related to the failure to file required annual bedbug reports, indicating ongoing concerns with compliance to basic health and safety requirements.

The building has also faced multiple Environmental Control Board violations related to construction safety in September 2018, including issues with scaffold stability and unsafe housekeeping practices during construction, though these were all resolved with penalties totaling $10,000. There were also some early concerns about rodent activity, with inspections in early 2018 showing evidence of rats, though the building passed subsequent inspections. The property has experienced periodic issues with required energy reporting and compliance, including violations in 2020 and 2021 for failing to file benchmarking reports and display energy efficiency scores, though these violations were dismissed or resolved based on subsequent corrections.

Initial rodent inspections in 2018 showed activity, but later inspections passed. Construction-related permits were regularly issued between 2018 and 2020, indicating ongoing work during the building's early years, with specific permits showing work related to plumbing, electrical, and other systems. While the building has generally resolved most of its historical violations, the recurring bedbug report violations stand out as the most significant ongoing compliance issue as of 2025.
