133 Sunnyside Avenue, Brooklyn, NY 11207

133 Sunnyside Avenue is a three-story, two-family residential building constructed in 1910 and currently owned by Lucie Regnerova. The property has experienced several significant maintenance issues in recent years, most notably a heat and hot water problem affecting the entire building in December 2024, which resulted in violations that required corrective action. The building has a concerning history of water-related issues, with multiple reports of heavy water leaks in 2019 and more recently in 2022, including a slow water leak noted in 2022, though most of these incidents were closed without violations.

Other notable problems include mold outbreaks in 2022 and 2019, an electrical power outage in 2019, and various safety concerns including a sprinkler system issue in 2019, all of which were investigated by the Department of Housing Preservation and Development. The building has also faced multiple housing maintenance code violations, with significant issues documented in 2022 and 2024. These include an infestation of mice in apartment 2A (December 2024), unpermitted cooking facilities, unauthorized storage of household items in public hallways, and various maintenance problems in apartment 1 such as water leaks, floor damage, and ceiling painting requirements.

The property had an illegal conversion complaint filed in April 2023, which was still being processed as of January 2025. Historical records show rodent control efforts in 2015-2016, with one initial inspection failing to meet compliance standards in August 2016. While many of the documented issues have been addressed and closed, the recurring nature of water-related problems and the recent heating system violations suggest ongoing maintenance challenges.
