Data Question

Department of Finance (DOF), Department of Housing Preservation and Development (HPD)

Community Preservation Corporation (CPC) is in the process of bringing in the above mentioned files inhouse. I am trying to define each field for our use. I have come across about 115 data fields in these three file that require some field definition. The given field description for these 115 are either blank or incomplete. So just wondering if you could help me to get a better field description for these 115 - so we can define each field and with right description for our users.

There is a fourth file we are bringing inhouse (PLUTO) which I was able to get the definition for its fields - so I was able to define them correctly in our database with the proper data definition

Appreciate your help.

Data Question

Department of Finance (DOF)

Hi NYC Open Data Team,
 
I am currently developing a data pipeline to analyze property tax exemptions for municipal housing research. I am working extensively with the Property Exemption Detail dataset (muvi-b6kx) and have encountered some inconsistencies in the underlying data logic. Is there a specific technical lead or subject matter expert I could contact directly for detailed inquires?

Hello, we recognize the issue you are flagging. The Open Data team is working on enhancing this dataset to have a functional calendar year and date column for optimized use for our end users. To attempt the filtering you are doing you may need to export the subset of information you need and attempt to do further analysis off of the portal.

IN the meantime we ask for you patience as we prioritize this dataset's enhancement through the remainder 2026

Data Question

Department of Housing Preservation and Development (HPD)

Hello,

. We're looking to use your Housing Maintenance Code Complaints dataset (ygpa-z7cr) on NYC Open Data to match heat complaints to buildings by BBL for our heating operations.
We have a few questions:

1. Timeliness: The dataset appears to refresh about daily. Is there any way to get this complaint data sooner? Can you share why there’s typically a delay—e.g., do complaints need to be vetted or processed through your systems before they’re published? Also, what time of day does the Open Data refresh run? We’d like to pull the data soon after it’s been refreshed.

2. Violations: What is the minimum or typical time from a heat complaint to HPD issuing a violation (or taking enforcement action)? We want to understand the timeline for prioritization.

3. 311 vs Open Data: We’ve looked at NYC 311 heat/hot water complaints, but they don’t include BBL and don’t line up 1:1 with your dataset. From HPD’s perspective, are there drawbacks to using 311 for heat complaints (e.g., different scope, status rules, or compliance) if we can get those sooner? We want to know whether 311 is suitable for building-level heat complaint awareness or if we should rely only on your Open Data feed.

Thanks for maintaining this dataset and for any guidance.

Best regards,

Data Question

New York City Fire Department (FDNY)

My name is *** and I am a graduate student at *** working on a research project examining EMS response time patterns in New York City. For our analysis, we are using the publicly available EMS Incident Dispatch Data published on NYC Open Data (https://data.cityofnewyork.us/Public-Safety/EMS-Incident-Dispatch-Data/76xm-jjuj/about_data).
Our project investigates whether high volumes of lower-acuity calls are associated with slower response times for the most critical emergencies, with the goal of building an interactive tool that lets users explore how response times might change if some lower-acuity calls were redirected to alternative care pathways.
To conduct this analysis, we need to correctly classify calls by urgency using the FINAL_SEVERITY_LEVEL_CODE field, which contains numeric values ranging from 1 to 8. However, the dataset documentation does not include a code key explaining what each value represents. Without this, we are unable to reliably distinguish high-acuity from low-acuity incidents.
Would you be able to share a reference document or brief explanation of what each severity level code corresponds to? Any guidance on the clinical or operational meaning behind the scale would be greatly appreciated.

I am encountering challenges synchronizing with this dataset. Old records intermittently appear with new timestamps in a way that inhibits retrieving incremental updates from this dataset.

Issue: Older records intermittently show with newer "created_at" timestamps. Additionally the unique_key column appears to not be unique - based in incrementally pulling new records i have higher counts of total records locally for each timeframe but no duplicates when grouped by unique_key.

When you query for the min/max :created_at grouped by year and month - data for all timeframes shows new records. [1]

Note: this may be related to Inquiry number 12263.

Thank you for reaching out. The “created_at” timestamp is reflective of how we update the dataset. Rather than adding new rows, the full dataset is replaced each time, and that is when that timestamp is populated. This means that older records can have a “created_at” timestamp that is more recent than the date of the record itself.

Could you clarify your issue with the unique keys? I am not sure I understand the issue there.

Let me know if there is anything else we can help with,

My question, specifically is about the "MTA Camera" violation records. I have been working on a project to geocoded all parking violations. The issue is that many of the MTA records either contain no value for "County" or the value for "County" is incorrect. Is it possible to have the data contain the correct information? I would be glad to provide examples to anyone who would like to review. This is not just in the 2026 file, but the previous ones as well. Thanks

Every year, I download data on tobacco retail dealer and electronic cigarette dealer license counts in NYC using the query tool on NYC Open Data. When I tried to do the same this year (e.g., active tobacco licenses in 2026), the numbers seem very incorrect. For example, according to the dataset on tobacco license caps per community district, there should be 3,823 active tobacco retail dealers this year. But when I use the general business license dataset and filter by tobacco licenses and license expiration date, only ~1800 licenses show up as being active this year. I wonder if there might be a data error.

Mayor's Office of Management and Budget (OMB)

I had a couple of questions regarding the variables related to planned and actual obligations:

The dataset includes the variable PLAN (planned and obligated budget). Could you clarify which entity determines this planned budget? Specifically, is the planned amount set primarily by OMB as part of the city’s financial plan, or does each agency determine its own planned obligation levels within the approved budget framework?

I also noticed that there are differences between PLAN and ACTUAL obligations. In cases where ACTUAL obligations are lower than the planned amount, how are the remaining funds typically treated? For example, are unspent funds:
1. carried over to the agency’s budget in the following fiscal year,
2. retained as some form of agency-level reserve or discretionary balance, or
3. returned to the city’s general fiscal resources?

Hello, I am an undergraduate student at Kennesaw State University studying data science and analytics.

The official AWS marketplace webpage for the database,

says that the bucket can be accessed with no account (although I do have one if necessary) using "aws s3 ls --no-sign-request s3://nyc-tlc/“. However, my attempts at the same command and similar alternatives have resulted in the following error:
"An error occurred (AccessDenied) when calling the ListObjectsV2 operation: Access Denied”.

Data Question

Department of Transportation (DOT)

I would like to request more granular location data on the start and end locations of trips in the trip table of the NYC Citywide Mobility survey. I’m a PhD student and I am conducting research to estimate the preferences people have over different modes of transport around New York City. I want to estimate how cycling infrastructure like cycle lanes, bikeshare stations, and modal filters have impacted cycling and other mode shares through the city, and the impact of this on congestion, transport accidents, and air pollution.

I will seek to build a model that will be able to evaluate how future policies (e.g., new cycle lanes/ modal filters) will impact mode shares, congestion, accidents, and air pollution. I note that this research aligns with NYC's own priorities including enabling more people to enjoy walking and cycling, making roads safer for everyone, and reducing congestion.

Currently, the trips table in the mobility survey aggregates the start and end locations into 10 survey zones that cover the whole of NYC. Such a high level of aggregation will not allow me to answer my research questions, as I will not be able to ascertain the routes people took around the city. Having a lower level of aggregation, like census tracts, would still protect survey participants addresses while allowing rigorous research.

If you do not have the authority to disclose this research could you give me the contact details of the team responsible for the Citywide Mobility Survey within the NYC DOT?

I am happy to provide any information that you require from me.

I look forward to hearing from you.

Data Question

New York City Police Department (NYPD)

Is there any legacy training data available? I'm a student pursuing a potential research project, but the constraint on the NYPD MoS table being only current members makes certain questions difficult to answer. I assume it's not a privacy issue, as retired officers are included in CCRB data, so I'd like to know if NYPD data on retired officers is kept somewhere accessible.

Data Question

Taxi and Limousine Commission (TLC)

I have a question about the AAR flag ("access_a_ride_flag") in the HVFHV data set. What process triggers this to be a "Y" for an individual trip? Is the trip data cross referenced with Access-A-Ride trip data? Or is there a process that enables the trip data to flag an AAR trip automatically? Would love to know more about how AAR trips are tagged.

The reason I am asking is I recently developed a dashboard to visualize the HVFHV data (https://nycfhv.urbanflows.net/) and I am curious what exactly the AAR flag is indicating. Thank you.

The access_a_ride_flag column in the HVFHV trip data is reported to us through the HV companies. For more information about the AAR program, please visit https://www.mta.info/accessibility/access-a-ride.

The MTA may be able to help regarding your question about trip data being cross referenced with AAR data, as we are not the operators of the AAR program.

Data Question

Department of Buildings (DOB)

Hello NYC Open Data Team,

I am currently analyzing the ECB Violations dataset to identify buildings that failed to comply with Local Law 84 (Benchmarking) for the 2024 reporting year. However, I am unable to locate these specific records.
Specifically, I am looking for:
1. A list of buildings cited for failing to report LL84 data for the 2024 cycle.
2. Violations related to buildings that failed to comply with the GHG Emissions declared by LL 97.
Could you please clarify if these records are housed in a different dataset, fwiw I checked the DOB Violations dataset as well but couldn't find it. There should be around 3000-3500 buildings that failed to comply with LL 97 with penalties that they paid.

Thanks,
*****

Dear NYC Open Data Team,
I hope this email finds you well.
I am a PhD student in economics at working on research related to education, urban transportation, and public policy.
I am currently exploring the NYC school attendance data resources for my research and wanted to utilize the public school attendance statistics. I found the relevant webpage and attempted to download the attachment named School_Attendance_Statistics.xlsx. However, after downloading and opening the file, I noticed that it is completely empty and contains no data.
Could you please help me look into this issue and send me the correct file with the data? Alternatively, if there is a different or preferred method to properly access these statistics, I would greatly appreciate your guidance.

New York City Police Department (NYPD)

What does "Null" mean in the data set, for example under "Perp_Sex"? Does it indicate a lack of data (meaning the NYPD officer left the category blank) or an unknown? Similarly, is "Null" different from "Unknown," an option under "Perp_Race"? Is "Unknown" an option the NYPD officer can select, as opposed to "Null" indicating no data entered?

Yes, that’s correct, the data has not been updated since September 2025. We pause the Open Data updates until the PMMR (October 2025 data) is released. We always do this pause but it is extended because of the publication date of March 3. We expect to update the portal a few days after publication and resume monthly updates (on the typical two-month lag) later in the month.

You are seeing this message because the dataset has been removed from the portal. Below is the business reason from the Department of Housing & Preservation (HPD). You will need to access data at the new dataset endpoint (ygpa-z7cr)

Removal reason from HPD
"With the release of the Housing Maintenance Code Complaints and Problems dataset at https://data.cityofnewyork.us/d/ygpa-z7cr, which merges the Housing Maintenance Code Complaints dataset and the Complaints Problems dataset, HPD will sunset and archive this dataset on or after January 31st, 2024. This change will make it easier for everyday New Yorkers to link complaint problems to building addresses, allowing the public to more easily identify complaints and complaint problems that have been issued in their buildings.
Should you have concerns, suggestions, or questions about this change, please email the HPD Open Data team at opendata@hpd.nyc.gov."

Department of Buildings (DOB)

Hello!
I was analyzing the number of stalled construction sites per date and came accross some irregularities. Some days seem to simply lack an update with the appropriate number of buildings and other days seem to have double the number of stalled construction sites. For example I find 0 stalled construction sites on 2013-12-20. Then again I find 1,100 sites on 2014-05-20, which is double the number of sites registered the day before and after.
Can you think of any technical reason why this happens?
Thank you!

It is possible that you are counting by instances of complaints by DOB run date, rather than by the date the unique complaint was received.

Hi there!
The number of complaints for 1G Stalled Construction Site has gone down dramatically over the past years. Is there a new and different complaint category that complaints about stalled construction are categorized into, or do you just see a trend in fewer construction sites being stalled? Also: Do you register repeat complaints about the same building somewhere?
Thank you very much!

Hundreds of newly filed jobs that I sourced from this dataset no longer appear as of today. Encountered no challenges with this dataset and my refined query over several months, something seemingly changed over the weekend and dropped thousands of rows that were previously accessible. BIN information pulls up correct permitting information in DOB NOW but not in OpenData— for example: searching 4625823 in DOB NOW shows the recently filed Q01339840-I1 permit but now returns no activity in the dataset. This is a significant issue for my workflow and I'm sure impacts many, many others. Need follow-up + resolution on this ASAP, please!

Data Question

Department of Buildings (DOB)

Why are these DOB datasets like this one and others so incomplete? Besides often lagging months behind, they are only a subset of the data available on the DOB websites and often exclude entire buildings' data. DOB provides no API or other facility for programmatically accessing the databases, and actively blocks scraping the websites. Aren't they out of compliance with Local Law 11?
