6815 11th Avenue, Brooklyn, NY 11219
The three-story, five-unit residential building at 6815 11th Avenue in Dyker Heights, owned by Nikolaos Atsidis and built in 1920, has experienced several significant maintenance and compliance issues over the past five years. Most notably, there is an ongoing pattern of non-compliance with the Housing Maintenance Code's bedbug reporting requirements, with open violations from 2022 through 2024 indicating failure to file the mandated annual bedbug reports.
The building had an emergency door-related issue reported in June 2025, though this was resolved shortly thereafter. The building's recent history includes a notable environmental control board violation from November 2020, when an improperly supported air conditioning unit at the second floor level was found to be maintaining by three loose bricks near a public entrance, for which a $2,500 penalty was imposed and later resolved.
This followed an illegal conversion complaint in November 2020, which resulted in an Oath violation. A subsequent violation was recorded in February 2021 regarding failure to certify correction on an immediately hazardous (Class 1) violation, though this was dismissed in March 2021 with the payment of an invoice. The only bedbug-related report on record was filed in April 2021 for the period of November 2019 to October 2020, showing no infested units, eradicated units, or re-infested units, suggesting the building was bedbug-free during that reporting period.
