Augrented Insights Report for 335 21st Street

The two-unit building at 335 21st Street in Sunset Park, owned by Rose Marsella, has a relatively long history of maintenance issues since its construction in 1899 as an Old Law Tenement. The most recent concerns, as of May 2025, include unresolved sanitary conditions related to garbage/recycling storage that resulted in violations being issued by HPD.

Earlier in 2025, there were reports of mold and water leaks/damp spots, though HPD was unable to complete inspections for these complaints. The building has experienced recurring sanitary issues, particularly with garbage/recycling storage, with similar complaints in 2024, 2022, and 2020. Multiple inspection attempts for various complaints have been unsuccessful, including reports of electrical concerns (outlets/switches and wiring), pest issues, and paint/plaster problems in 2022, as well as a dog-related sanitation complaint in 2023.

The Department of Buildings records reveal several complaints relating to unauthorized work and inspection access issues between 2020 and 2024, including multiple reports of work without a permit and violations of stop work orders, though most were ultimately unsubstantiated upon inspection. Notably, there was an emergency plumbing complaint regarding water supply in December 2020 that was resolved quickly. The building's maintenance history suggests ongoing challenges with both interior conditions and compliance with building regulations, with particular attention needed for the recurring sanitation issues observed over multiple years.
