Is 643 Cauldwell Avenue, Bronx getting better or worse?
Certifications are being filed faster than new violations come in. 12 certifications filed against 2 new Class C 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 643 Cauldwell Avenue, Bronx?
Since September 28, 2023, certifications were filed on 61 Class C violations: 59 by the original certify-by date, 2 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 643 Cauldwell Avenue, Bronx have active DOB violations?
Yes. 3 active DOB violations, most of them for construction. The newest was issued October 17, 2025. 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.
Has DOB received complaints about 643 Cauldwell Avenue, Bronx?
Yes. 9 DOB complaints in the last 12 months. The newest was filed August 15, 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 643 Cauldwell Avenue, Bronx marked completed?
Yes. 1 completed HPD emergency repair order since September 28, 2023: a general construction order, opened December 15, 2023, awarded for $530. 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.
Are any DOB work permits in effect at 643 Cauldwell Avenue, Bronx?
Yes. 1 DOB work permit in effect, for Sidewalk Shed work, issued October 27, 2025. A permit in effect allows the work it names. It does not mean the work has started or finished, or that it fixes any violation on this page.
Is 643 Cauldwell Avenue, Bronx 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 643 Cauldwell Avenue, Bronx 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.

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.
