Construction Permits in the Last 30 Days

The dataset contains locations and attributes of building construction and alteration permits applied for and approved by the District of Columbia Department of Buildings. These data are shared via an automated process where addresses are batch matched (geocoded) to the District's Master Address Repository. Users may find that some data points will contain 0,0 for X,Y coordinates resulting in inconsistent spatial locations. Addresses for these data points could not be automatically geocoded and will need to be manually geocoded to 'best fit' locations in DC.

Parking zones created from collected sign data throughout Washington DC. Parking Zones are created between two parking restriction signs of the same type that point at each other, or between a sign and an intersection.

Wells are defined by 21 DCMR Chapter 18 as any test hole, shaft, or soil excavation created by any means including, but not limited to, drilling, coring, boring, washing, driving, digging, or jetting, for purposes including, but not limited to, locating, testing, diverting, artificially recharging, or withdrawing fluids, or for the purpose of underground injection. The Department of Energy & Environment's Regulatory Review Division reviews permit applications to install wells in private and public space through the Department of Licensing and Consumer Protection and the District Department of Transportation.

The dataset contains locations and attributes of blocks, created as part of the Master Address Repository (MAR) for the Office of the Chief Technology Officer (OCTO) and participating DC government agencies. The blocks used street centerlines information from DDOT. Blocks include named alleys in DC (such as 'WALTER ALLEY NE'). A block represents a street segment which usually has two bordering streets. The coordinates for the blocks are located at the midpoint of the street segment. More information on the MAR can be found at https://opendata.dc.gov/pages/addressing-in-dc. The data dictionary is available: https://opendata.dc.gov/documents/2a4b3d59aade43188b6d18e3811f4fd3/explore. In the MAR 2, the BlocksPt is called BLOCKS_PT and is primarily based off of street data from DC Department of Transportation's Roads & Highways database, it also features additional useful information such as created date, last edited date, begin date, and more.

Permits are how the City regulates construction. There are several different types of permits, depending on the type of construction. This table includes all permits issued through the Development Services permit center: building, mechanical plumbing, garage sales and others. Data is updated hourly during business hours. For more about permitting, please visit the Development Services website.

The Mowing Operations dataset provides detailed information on scheduled mowing operations across District-managed properties. It includes data fields such as mowing dates, mowing frequency, and specific location identifiers like property names and addresses. The dataset also categorizes mowing areas by agency or property type—such as schools, parks, and government facilities—and includes timestamps showing the last time the information was updated. Developed to promote transparency and community engagement, the dataset allows residents to see when and where mowing services are planned throughout the season.
