NYC filing index, Q3 2026: what the public record produced this quarter

DOB permits issued, by work type

Permits issued by the Department of Buildings through the BIS system, counted by the work type on the permit and the month of issuance. Work types are the trade on the permit: plumbing, mechanical, sprinkler, boiler and the rest. Equipment and construction permits that carry no work type appear as "Not stated".

DOB NOW job filings, by job type

Job applications filed in DOB NOW, counted by job type and month of filing. A job filing precedes the permit; new buildings, alterations and full demolitions each show up here first.

HPD violations opened, by class

Housing Maintenance Code violations issued by HPD, counted by class and the month the notice of violation was issued. Class C is immediately hazardous (heat, hot water, gas, lead paint); class B is hazardous; class A is non-hazardous.

Certificates of occupancy issued

Certificates of occupancy issued through DOB NOW, counted by the month of issuance. Each one marks a building, or part of one, cleared for use.

Deeds recorded (ACRIS)

Deed documents recorded in ACRIS across the five boroughs, counted by the month of recording. A deed is a change of owner, and a new owner is a new buyer of every building service.

Filing to issuance: how long a DOB permit takes

For permits issued in Q3 2026, the median gap between the filing date and the issuance date was 0 days (mean 30.4 days, across 1,617 permits with both dates). Negative or missing gaps are excluded. The median is the number to plan around: half of permits issue within it. A median of zero means more than half of these permits were issued on the day they were filed, which is normal for BIS renewals and professionally certified work; the mean shows how long the rest take.

What the quarter means for each trade

The counts above are the raw material for a lead feed. Read by trade, they say roughly how many accounts in New York produced a buying signal of each kind this quarter.

• New buildings and alterations. 39,225 new-building and alteration job filings this quarter. Every one of them ends with a building that needs access control and cameras, a fire alarm and sprinkler sign-off, a post-construction clean and an electrical fit-out: security, fire protection, commercial cleaning, electrical.
• HPD class C violations. 59,085 immediately hazardous violations opened, most of them heat, hot water and gas. The owner has a short correction window and a contractor to find: HVAC, plumbing.
• Certificates of occupancy. 3,868 certificates issued. A CO means tenants move in within weeks, and the building goes from a site to an operating property that needs guarding and cleaning on a contract: security, commercial cleaning.
• Deeds. 15,789 deeds recorded. A new owner reviews every vendor in the first ninety days and usually inherits a roof and a facade with deferred work: property management, roofing, masonry.
• Demolition. 680 full demolition job filings. Each one is a site that needs containers and hauling before anything else happens: waste removal.
• Mechanical, boiler and sprinkler permits. 128 permits with an MH, BL or SP work type. These name the system going in, and the contractor who installs it is rarely the one who services it afterwards: HVAC, fire protection.

Method and sources

Each series is one SoQL query against one dataset on NYC Open Data, grouped by calendar month of the date field (and by the category field where there is one), run once for Q3 2026 and once for Q3 2025. Blank categories are shown as "Not stated". The lag figure reads every permit issued in the quarter with both dates and takes the median and mean of issuance minus filing, in days.

Regenerated quarterly on this URL with scripts/filing-index.mjs; counts reflect the datasets as of the generation date, and late-entered records can change prior quarters. The DOB Permit Issuance dataset covers permits in the BIS system; permits for jobs filed in DOB NOW are counted at the job-filing stage in the second table.
