112 Jamaica Avenue, Brooklyn, NY 11207

The three-story, two-family residential building at 112 Jamaica Avenue in Cypress Hills, owned by Liang Qin Song and constructed in 1920, has experienced several significant events in recent years that warrant attention. Most notably, in December 2021, the building sustained serious damage from a gas explosion that occurred approximately 20 feet wide by 8 feet tall, primarily affecting the third floor with burn damage and openings through walls and roof sections.

This incident resulted in active violations requiring the owner to retain a New York State Professional Engineer to evaluate the building, with repairs needing to be completed and signed off by March 2022. The building's maintenance history shows multiple Department of Buildings complaints and violations in December 2021 alone, including issues with illegal plumbing work, building vibrations affecting structural stability, and failure to maintain building conditions, though one of these complaints was found to warrant no violations upon inspection. Prior to these incidents, the property had been the subject of an Environmental Control Board violation in December 2019 regarding unauthorized construction work that was found to deviate from approved plans, with a $1,250 penalty imposed.

The building's maintenance record shows consistent compliance with bedbug reports from 2021 through February 2025, with no infestations reported in any of the five consecutive annual filings. The property also passed an initial rodent inspection in June 2012, and while there were several complaints filed in 2019-2021 relating to various building issues, most were closed without finding violations. Active violations related to the 2021 gas explosion and building damage incident remain as the primary concerns on the building's current record, though there is no evidence of ongoing pest issues based on recent bedbug reporting history.
