Questions about this building

Does 748 St Marks Avenue, Brooklyn have open violations?

Yes. 748 St Marks Avenue, Brooklyn had 35 open violations on September 26, 2026: 34 from HPD and 1 from OATH/ECB. 13 are Class C, the class HPD treats as immediately hazardous.

Is 748 St Marks Avenue, Brooklyn getting better or worse?

New violations are coming in faster than certifications are filed. 10 new Class C against 1 certification filed in the last 180 days. That window ends September 26, 2026. It compares certifications filed with new Class C violations, and it describes what happened, not what anyone intends.

When were certifications filed on Class C violations at 748 St Marks Avenue, Brooklyn?

Since September 28, 2023, certifications were filed on 22 Class C violations, all 22 by the original certify-by date. HPD now marks 1 of them Invalid Certification. A certification is the filing, dated when it was made, not HPD's acceptance of it. It is compared with the original certify-by date on the notice. A granted postponement moves that date and the city's data keeps only the first, so a certification counted after it may still have met a postponed date.

Does 748 St Marks Avenue, Brooklyn have active DOB violations?

Yes. 2 active DOB violations, most of them for elevators. The newest was issued January 26, 2021. The Department of Buildings writes these separately from HPD's housing violations, for things like boilers, elevators, facades, construction and energy filings. Each one stays active until DOB resolves or dismisses it.

Is 748 St Marks Avenue, Brooklyn in housing court?

Yes. 1 open housing court case, opened May 18, 2026. HPD takes buildings to housing court to get violations fixed and heat and hot water restored, and it joins tenants' own repair cases, called tenant actions. A case stays open until the court closes it.

Has DOB received complaints about 748 St Marks Avenue, Brooklyn?

Yes. 2 DOB complaints in the last 12 months. The newest was filed September 3, 2026. Anyone can complain to DOB about a building or the work going on in it, and DOB then inspects and decides whether there is a violation. A conversion complaint says an apartment may have been added or changed without approval. It is a complaint, not a finding.

Are any HPD emergency repair orders at 748 St Marks Avenue, Brooklyn marked completed?

Yes. 2 completed HPD emergency repair orders since September 28, 2023, awarded for $23,075 in total. The most recent of the 2, a general construction order, was opened July 9, 2026. 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 748 St Marks Avenue, Brooklyn?

ENERGY STAR score 94 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 748 St Marks Avenue, Brooklyn covered by Local Law 97?

Yes. It is on DOB's Local Law 97 covered buildings list. Covered under Article 321, the path for certain affordable housing and houses of worship (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 748 St Marks 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 748 St Marks Avenue, Brooklyn built?

The city's record gives 1928 as the year 748 St Marks Avenue, Brooklyn was built, in the Department of City Planning's PLUTO tax-lot file. The same file classes it as an elevator apartment building with 6 floors.

How many apartments does 748 St Marks Avenue, Brooklyn have?

The Department of City Planning's PLUTO tax-lot file lists 36 residential units at 748 St Marks 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 DOB violations, HPD's housing court cases, DOB complaints, 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 DOB violations, HPD's housing court cases, DOB complaints, 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.
