233 Frost Street, Brooklyn, NY 11211

233 Frost Street is a 3-story, 6-unit Old Law Tenement building constructed in 1930, currently owned by Evelyn Gargano and located in Williamsburg, Brooklyn. The building has experienced several significant issues in recent years, with the most immediate concern being a March 2025 complaint about indoor air quality related to construction dust, which was followed by a Department of Health advisory to address the condition. There have been multiple incidents of work without permits in occupied dwelling areas, including two complaints in 2023 and 2025, though inspections found no violations at those times.

Of particular concern are eight active violations related to failures to file external low-pressure inspections between 2018 and 2023, and two violations from 2019 regarding the intention to revoke approvals and permits under plumbing jobs due to the suspension of a master plumber's license. The building has a history of plumbing issues, with multiple complaints in January 2019 resulting in partial stop work orders. An active Environmental Control Board violation from 2019 remains on record regarding construction work not conforming to approved plans, with a penalty of $625.

The property has undergone several inspections with varying results, including a 2018 compliance audit that resulted in DOB violations for construction work. Bedbug reports indicate a significant problem in 2019-2020, with six units affected at that time, though subsequent reports from 2021 through 2025 show no infestations or eradication efforts required. The building's permit history shows multiple permits issued for various work, particularly in 2018 and 2019, including exterior and plumbing work. Recent maintenance compliance must be closely monitored, particularly regarding the active violations related to inspections and the March 2025 indoor air quality issue.
