Building Permits

A. SUMMARY
The dataset includes details of all building permit applications filed with the Department of Building Inspection. Permit numbers and associated information may be repeated in multiple rows if there are multiple addresses associated with the permit. To view the deduplicated building permits dataset with just the primary address, click here. Data is uploaded nightly by DBI. Users can view associated addenda, routing, and inspection information for each permit in the dataset online through DBI’s Permit Tracking System here.

B. HOW THE DATASET IS CREATED
The dataset is created by extracting permit characteristics and key dates (including permit filing, issuance, and completion dates) from DBI’s Permit Tracking System.

C. UPDATE PROCESS
The process that builds this dataset will run nightly and include all permits entered into the system up to the time of the refresh (see the “data as of” column in the dataset).

D. HOW TO USE THIS DATASET
Users can use this dataset to search for all permits associated with a specific address or parcel number and view characteristics like addresses, permit descriptions of work, unit counts, valuations, etc. If the analytical objective is to measure permitting trends for all addresses, we recommend using the primary address building permits dataset.

Note: if you need to open this dataset in Excel, use one of the pre-filtered datasets. Opening the main dataset in Excel will cause some data to be lost as there are more than one million rows in the full dataset.

1. Building Permits filed on or after January 1, 2013
