ENERGY STAR score 100 for 2024, against a median of 67 for Multifamily Housing that year. Buildings over 25,000 square feet report their energy use to the city every year under Local Law 84. The ENERGY STAR score runs from 1 to 100 and compares a building with similar ones nationwide; 50 is the national median. The score is the one the city publishes, and this page never estimates a Local Law 97 emissions penalty. A lot that reported several properties in one year is not scored here.

When was 551 Ralph Avenue, Brooklyn built?

How many apartments does 551 Ralph Avenue, Brooklyn have?

The Department of City Planning's PLUTO tax-lot file lists 3 residential units at 551 Ralph Avenue, Brooklyn. The count is for the whole tax lot.

Where do these numbers come from?

From New York City's own data: HPD housing violations and OATH/ECB hearing results, read whole rather than sampled. It also draws on HPD's housing court cases, Local Law 84 energy reports and the city's PLUTO tax-lot file. This page is current through September 26, 2026. The city's data changes daily, so a violation certified after that can still show as open here; the city's own records are the authority on what is open today.

Sources. HPD housing violations and OATH/ECB hearing results, plus HPD's housing court cases, Local Law 84 energy reports and the city's PLUTO tax-lot file. Counts cover HPD Class B and C violations from the last 3 years that HPD still shows open, and OATH/ECB summonses from the same 3 years that the city still shows active. The city's own pages can show more, never fewer.
