374 13th Street, Brooklyn, NY 11215

The three-unit, three-story brownstone at 374 13th Street in South Slope, owned by Ralph Denzer and built in 1899, has experienced several concerning issues in recent years, particularly relating to pest control and building compliance. Most notably, the property has open violations dating back to 2021 regarding the failure to file required annual bedbug reports, a recurring issue over multiple years. Recent complaints in mid-2025 have brought attention to both rodent sightings and chemical odor concerns, though the Department of Health and Mental Hygiene inspections in June 2025 found no violations, except for an advisory regarding the chemical vapor incident.

The building was served with a partial vacate order in July 2025 following an illegal conversion complaint, though this was relatively recent and may still be under review. There have also been two complaints about work being done without proper permits in recent months, one of which was investigated immediately and found not to warrant any violations. The building's maintenance history shows a mix of compliance and violation issues, particularly with pest control matters.

While recent rodent inspections in July 2025 passed, the property has been subject to various rodent-related complaints, with the most recent June 2025 complaint being processed through both 311 and the Housing Maintenance Code system. The Department of Buildings records indicate an ongoing pattern of building code compliance issues, though many recent complaints have been resolved without violations being found. The property has an established history dating back to 2010 showing varied results in rodent inspections, including one failure in early 2010 for unspecified reasons, though subsequent inspections that same year passed.
