Questions about this building

Does 123 Linden Boulevard, Brooklyn have open violations?

Yes. 123 Linden Boulevard, Brooklyn had 109 open violations on October 10, 2026: 107 from HPD and 2 from OATH/ECB. 31 are Class C, the class HPD treats as immediately hazardous. The oldest open HPD violation has been open 3 years, since July 4, 2023.

Is 123 Linden Boulevard, Brooklyn getting better or worse?

Certifications are being filed about as fast as new violations come in. 12 certifications filed and 13 new Class C in the last 180 days, neither far ahead. That window ends October 10, 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 123 Linden Boulevard, Brooklyn?

Since October 12, 2023, certifications were filed on 26 Class C violations, all 26 by the original certify-by date. 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 123 Linden Boulevard, Brooklyn have an OATH hearing coming up?

Yes. A hearing on a DOB summons is set for October 28, 2026. DOB summonses are heard at OATH, the city's hearings office, and OATH can move a hearing to a later date. When nobody shows up, the summons is decided by default, the costliest way one ends.

Does 123 Linden Boulevard, Brooklyn have active DOB violations?

Yes. 18 active DOB violations. The newest was issued June 20, 2023. 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 123 Linden Boulevard, Brooklyn been in housing court?

Yes. 7 housing court cases here since 2024, most of them tenant actions. 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 123 Linden Boulevard, Brooklyn?

Yes. 4 DOB complaints in the 12 months to September 25, 2026. The newest was filed August 26, 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 123 Linden Boulevard, Brooklyn marked completed?

Yes. 1 completed HPD emergency repair order since October 12, 2023: a general construction order, opened August 16, 2024, awarded for $1,850. 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 did the latest facade report find at 123 Linden Boulevard, Brooklyn?

Rated SWARMP in the latest facade report, filed April 16, 2026 (inspection cycle 10). SWARMP means safe with a repair and maintenance program. Buildings taller than six stories must have their exterior walls inspected once in every inspection cycle under the city's Facade Inspection Safety Program (every five years under DOB's current rule), and each inspection report is filed with DOB as Safe, SWARMP (safe with a repair and maintenance program) or Unsafe. No Report Filed means DOB has no report for that cycle. The rating is from the latest filing and does not describe the facade today; DOB's page for the building shows anything filed since.

Does 123 Linden Boulevard, Brooklyn have a certificate of occupancy?

Its latest certificate of occupancy is a final one, issued April 12, 2022. A certificate of occupancy says how a building may be used and occupied. A temporary one lets people move in while work finishes and has to be renewed until DOB issues the final one. DOB's records here start in July 2012, so an older certificate may not show.

What is the ENERGY STAR score for 123 Linden Boulevard, Brooklyn?

ENERGY STAR score 34 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 the boiler at 123 Linden Boulevard, Brooklyn last inspected?

It has 3 boilers, all inspected in 2025, the latest on August 18. DOB requires a boiler in a building with 6 or more apartments to be inspected once every calendar year, with the report filed within 14 days of the inspection. Low-pressure boilers in residential buildings with 5 or fewer apartments are exempt.

When did 123 Linden Boulevard, Brooklyn last file its bedbug report?

On December 23, 2025, for the year to October 31, 2025. HPD asks the owner of every building with 3 or more apartments for this report once a year, covering November 1 to October 31, including buildings that had no bedbugs.

Is 123 Linden Boulevard, Brooklyn covered by Local Law 97?

Yes. It is on DOB's Local Law 97 covered buildings list. Covered from 2035 as an income-restricted 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 123 Linden Boulevard, 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.

Does 123 Linden Boulevard, Brooklyn have a property tax exemption?

The building has a 421-a tax exemption on DOF's 2026/27 roll. DOF lists its start year as 2020. An exemption lowers a property's tax bill by reducing its assessed value.

When was 123 Linden Boulevard, Brooklyn built?

The city's record gives 2017 as the year 123 Linden Boulevard, Brooklyn was built, in the Department of City Planning's PLUTO tax-lot file. The same file classes it as an elevator building with 20 floors.

How many apartments does 123 Linden Boulevard, Brooklyn have?

The Department of City Planning's PLUTO tax-lot file lists 467 residential units at 123 Linden Boulevard, 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 OATH hearing dates, OATH/ECB summonses from DOB and FDNY, DOB violations, HPD's housing court cases, DOB complaints, the Rent Guidelines Board's stabilized-building lists, DOF's exemption rolls, DOB facade filings, DOB NOW work permits, DOB certificates of occupancy, HPD emergency repair orders, Local Law 84 energy reports, DOB boiler inspection reports, HPD's annual bedbug reports, DOB's Local Law 97 covered buildings list, the city's PLUTO tax-lot file and DOF's property sales records. This page is current through October 10, 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 OATH hearing dates, OATH/ECB summonses from DOB and FDNY, DOB violations, HPD's housing court cases, DOB complaints, the Rent Guidelines Board's stabilized-building lists, DOF's exemption rolls, DOB facade filings, DOB NOW work permits, DOB certificates of occupancy, HPD emergency repair orders, Local Law 84 energy reports, DOB boiler inspection reports, HPD's annual bedbug reports, DOB's Local Law 97 covered buildings list, the city's PLUTO tax-lot file and DOF's property sales records. 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.
