490A Jefferson Avenue is a 4-story residential building constructed in 1910, featuring 9 units and classified as a New Law Tenement. The building, currently owned by We 490A Jefferson LLC, has experienced recurring issues with heat and hot water systems, particularly during the winter months, with multiple complaints documented between 2019-2022. Most recently, in early 2022, there were both apartment-specific and entire-building heating issues that required HPD intervention.

The building has also faced maintenance challenges, as evidenced by violations and service requests regarding the first-floor lobby's ceiling and walls, including water leaks and fire-retardant material concerns. A significant renovation period occurred around 2018-2019, during which several DOB violations were recorded, including unauthorized work and non-compliance with construction documents, though these were resolved with proper permit issuance. The property has demonstrated proactive pest management, with bedbug report filings from 2021-2024 consistently showing no infested units.

However, rodent activity has been a recurring issue, with the most recent inspection in June 2025 noting rat activity, though previous inspections in 2024 and 2023 showed different results. The building's maintenance history shows a regular pattern of code compliance inspections and violations, particularly focusing on public areas like stairwells and lobbies. Between 2022 and 2023, several environmental violations were addressed, including water leaks and issues with fire-retardant materials in common areas. The property has also undergone various system improvements, with multiple plumbing and electrical permits issued between 2018 and 2020, indicating ongoing maintenance and upgrading of building systems.
