About this dataset
Building permits issued in eight US cities, merged into one table: Chicago, New York City, Los Angeles, San Francisco, Austin, Seattle, Boston and Denver. The data comes from each city's own open data portal through data extraction and is refreshed every week. Each row is one issued permit: city, permit number, issue date, permit type and work type as the city states them, the work description, street address, ZIP code and coordinates, the project value stated on the application, permit status, a new-construction flag, housing units where the city records them, and the contractor's business name where the city publishes one. Each city publishes permits on a different site with its own field names, so getting one consistent table usually means maintaining eight separate feeds. The table is built for teams whose work follows construction activity: contractors and trade suppliers looking for new jobs, solar, roofing, HVAC and electrical sales teams, building-product manufacturers, and real-estate, lending and insurance analysts tracking what is being built where. The first collection holds 19,016 permits issued between 19 October and 4 November 2026; about 8,000 permits are added each week. Need the same weekly feed for your metros or counties, or only new construction above a project value, with contractor names? Ask Jason to build your own version.
What you can use it for
- Build a weekly lead list of new permits by city, permit type and project value. - Compare construction and renovation activity across the eight cities week by week. - Track new construction permits and housing units added where the cities record them. - See which contractors are pulling permits in New York, Austin, Seattle and Denver. - Match permit addresses against your own account or property lists to spot active work.
Coverage
Eight US cities: Chicago (IL), New York City (NY), Los Angeles (CA), San Francisco (CA), Austin (TX), Seattle (WA), Boston (MA) and Denver (CO). All permit types each city publishes as issued, every trade included (building, alteration, electrical, plumbing, mechanical and others). Permits issued from 19 October 2026 onwards; new permits are added every Thursday. First collection: 19,016 permits issued 19 October to 4 November 2026. By city: New York 7,910; Austin 3,316; Los Angeles 2,827; Boston 1,928; Chicago 1,644; San Francisco 746; Denver 331; Seattle 314.

How Jsonify collected this data
Nobody wrote a scraper for this. Someone described the data they wanted, in a sentence, and Jason, Jsonify's AI data engineer, took it from there.
He found the sources, worked out which fields to pull, tested the steps on a sample and scheduled the runs. The thread on the right is that conversation, retold with this pipeline's real steps.
From then on the pipeline runs itself. When a site changes and a run fails its checks, Jason repairs the pipeline and verifies a sample before publishing again.

Column explanations
- city: Chicago, New York, Los Angeles, San Francisco, Austin, Seattle, Boston or Denver. - state: two-letter state code. - permit_number: the city's permit number; city + permit_number is unique. - issue_date: date the permit was issued (YYYY-MM-DD). - permit_type: permit category in the city's own wording, e.g. Plumbing (New York), Bldg-New (Los Angeles), Long Form/Alteration Permit (Boston), Addition (Denver). - work_type: the city's sub-type or work class where it has one; in New York, all work types on the permit, comma-separated. - work_description: the work described on the permit; Denver publishes no description, so this repeats the permit class. - address: street address of the work site. - zip_code: ZIP code of the work site. - project_value_usd: estimated, declared or reported cost of the work stated on the application, in US dollars; empty where the city gives none. - contractor_business_name: the contractor's company name where the city publishes one (New York, Austin, Seattle, Denver); never a personal contact. - permit_status: status in the source when collected, e.g. Permit Issued, Open; empty for Denver. - new_construction: true for the city's own new-construction permit types (Chicago, Los Angeles, Austin, Seattle, Boston, Denver); empty for New York and San Francisco, which have no clean flag. - housing_units: change in housing units where the city records it (Chicago, Los Angeles, San Francisco, Austin, Seattle). - latitude, longitude: location of the work site, where the city provides it. - source_name: the portal the row came from, e.g. New York Open Data. - source_url: link to the permit's record in the source.
Version history
- v5
Raised the monthly new-permit limit from 35,000 to 50,000. Existing sources, fields, Thursday schedule and fourteen-day look-back are unchanged.
- v4
Corrected San Francisco permit labels, Los Angeles work subtypes, Seattle units-added mapping and combined New York work types.
- v3
Expanded to eight city permit sources with one unified table, company-only contractors, weekly fourteen-day checks and a 35,000 monthly cap. Initial coverage remains open until source exhaustion and successful publication are verified.
- v2
Use the latest saved permit issue date as the strict cutoff for future updates, preserving the existing fields, exclusions and monthly cap.
- v1
Add a private Chicago building permit collection with source-matched fields, new-permit-only updates, batch saving and a monthly limit. Scheduling remains off.
Repairs
When a source changes and a step fails, Jason's repair and its outcome are recorded here.
Quality checks
- v3Inconclusive
Full-table structural checks passed, and sampled records matched seven cities' live sources. Boston verification and reconciliation of source-count differences remain incomplete; no confirmed defects found.
- v2Inconclusive
Structural and append-only checks passed, and eight live-source samples matched. Five source permits are absent; permitted skips versus source drift could not be established.
- v1Inconclusive
Structural checks passed for all 1,208 permits, and eight live source spot-checks matched. Two qualifying source permits are absent without a verifiable exclusion explanation.
Limitations
- Permit types are not standardised across cities: each city's categories and wording are kept as published. Only new_construction is mapped to one meaning. - New York includes every work permit filed through DOB NOW (plumbing, sprinklers, mechanical, scaffolds and sidewalk sheds among them), so it supplies about four in ten rows. - Project value is the amount stated on the application and is empty for some permit types; in Austin it is filled for well under half of building permits. - Contractor business names appear only for New York, Austin, Seattle and Denver, and only from company-name fields. Some company names include a founder's name, and some Austin names carry source markers such as "**MAIN". - Owner, applicant and other personal contact fields are left out. In the first collection, 92 records whose free text contained personal information and 17 unreadable records were left out. - Each weekly run adds newly issued permits; later status changes to permits already collected are not updated. - City portals can lag permit issuance by several days; at the first collection the newest Los Angeles permits were from 31 October. - Denver data comes with the City and County of Denver's note that it is not for engineering purposes. - Source credit and changes: each city's rows come from its own open data portal, listed under Sources. New York rows come from NYC Open Data, "DOB NOW: Build – Approved Permits" (NYC Department of Buildings), as published at each weekly collection; the first collection read the version updated 5 November 2026. Changes made to every city's data: fields renamed into one shared set of columns; repeated records for one permit merged into one row (New York work types joined in work_type); personal name, phone and address fields removed; new_construction added from each city's own permit type. - This site provides applications using data that has been modified for use from its original source, www.cityofchicago.org, the official website of the City of Chicago.
