AI summary · updated June 2026

306 Cortelyou Road is a 3-story, 3-unit residential building constructed in 1910, currently owned by Fidelia Taveras. The building has experienced recurring issues with heat and hot water systems, particularly notable during 2019 when multiple emergency complaints were filed regarding both building-wide and apartment-specific heating problems. While some violations were resolved, a pattern of heating system maintenance concerns emerged during that period. More recently, in 2024, the building encountered rodent-related issues, with a rat sighting reported and investigated, though the property ultimately passed inspection with only minor violations noted.

The building currently has several open violations that require attention. These include multiple outstanding violations related to bedbug reporting requirements spanning from 2021 to 2024, and specific safety concerns involving carbon monoxide detector and smoke detector maintenance in Apartment 4 from 2019. The property also faces active penalties for failure to file required annual boiler inspection reports, with a balance due of $625 as of December 2024. Historical complaints show various maintenance issues over the years, including plumbing concerns in 2019 and concerns about building entrance door functionality. Despite these challenges, the building has demonstrated compliance with some inspections, such as recent rodent inspections in 2014 and 2024 showing passing results. An investigation into an alleged illegal conversion was conducted in 2023 but found no violations warranting enforcement action.
