Questions about this building
Does 1729 Caton Avenue, Brooklyn have open violations?
Yes. 1729 Caton Avenue, Brooklyn had 25 open violations on September 26, 2026: 25 from HPD. 16 are Class C, the class HPD treats as immediately hazardous.
Is 1729 Caton Avenue, Brooklyn getting better or worse?
Open violations are sitting, with little movement either way. 16 open Class C, with 3 certifications filed and 0 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.
When were certifications filed on Class C violations at 1729 Caton Avenue, Brooklyn?
Since September 28, 2023, certifications were filed on 4 Class C violations: 1 by the original certify-by date, 3 after it. 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 1729 Caton Avenue, Brooklyn have active DOB violations?
Yes. 3 active DOB violations, most of them for low-pressure boilers. The newest was issued December 1, 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.
What is the ENERGY STAR score for 1729 Caton 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 1729 Caton 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 1729 Caton 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 1729 Caton Avenue, Brooklyn built?
The city's record gives 1931 as the year 1729 Caton Avenue, Brooklyn was built, in the Department of City Planning's PLUTO tax-lot file. The same file classes it as a walk-up apartment building with 4 floors.
How many apartments does 1729 Caton Avenue, Brooklyn have?

Where do these numbers come from?

It also draws on DOB violations, the Rent Guidelines Board's stabilized-building lists, 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.
