Your details stay with us, and go only to the one firm you are introduced to. No lists, no resale.

Questions about this building

Does 640 Ditmas Avenue, Brooklyn have open violations?

Yes. 640 Ditmas Avenue, Brooklyn had 63 open violations on September 26, 2026: 63 from HPD. 13 are Class C, the class HPD treats as immediately hazardous.

Is 640 Ditmas Avenue, Brooklyn getting better or worse?

Open violations are sitting, with little movement either way. 13 open Class C, with 0 certifications filed and 5 new Class C in the last 180 days, too few to call a direction. That window ends September 26, 2026. It compares certifications filed with new Class C violations, and it describes what happened, not what anyone intends.

Are any HPD emergency repair orders at 640 Ditmas Avenue, Brooklyn marked completed?

Yes. 3 completed HPD emergency repair orders since September 28, 2023, awarded for $1,879 in total. The most recent of the 3, a lead paint order, was opened January 28, 2025. HPD orders an emergency repair when a hazardous condition cited in a violation, or in another agency's emergency order, is not corrected, and does the work itself or through a contractor. The amounts are what the orders were awarded for, not a bill: this page does not show what was charged to the property or whether it was paid. Orders for lab tests, such as dust-wipe and asbestos samples, are not counted.

What is the ENERGY STAR score for 640 Ditmas Avenue, Brooklyn?

ENERGY STAR score 8 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.

Is 640 Ditmas Avenue, Brooklyn covered by Local Law 97?

Yes. It is on DOB's Local Law 97 covered buildings list. Covered from 2026 as a rent-regulated building (DOB's list, March 1, 2026). Local Law 97 sets greenhouse gas limits for most New York City buildings over 25,000 square feet, and DOB's covered buildings list says which path each building is on. The list reflects DOB's records, which owners can ask DOB to correct. This page never estimates a penalty or says whether a building complies.

Is 640 Ditmas Avenue, Brooklyn rent stabilized?

The building has rent-stabilized apartments on its 2024 registration. That comes from the Rent Guidelines Board's list of buildings with at least one stabilized apartment registered that year. Buildings that registered late are left off, and a 421-a or J-51 building can leave stabilization when its tax benefit ends. A particular apartment's status is for NYS HCR to say.

When was 640 Ditmas Avenue, Brooklyn built?

The city's record gives 1920 as the year 640 Ditmas Avenue, Brooklyn was built, in the Department of City Planning's PLUTO tax-lot file. The same file classes it as a condominium with 4 floors.

How many apartments does 640 Ditmas Avenue, Brooklyn have?

The Department of City Planning's PLUTO tax-lot file lists 39 residential units at 640 Ditmas 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 the Rent Guidelines Board's stabilized-building lists, HPD emergency repair orders, Local Law 84 energy reports, DOB's Local Law 97 covered buildings list 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 page for this building is linked above.

Sources. HPD housing violations and OATH/ECB hearing results, plus the Rent Guidelines Board's stabilized-building lists, HPD emergency repair orders, Local Law 84 energy reports, DOB's Local Law 97 covered buildings list 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.
