Parking meter assets are used to manage and encourage turnover of curbside use on streets in Washington, DC. These assets are owned, operated, and maintained by the District Department of Transportation (DDOT), unless otherwise noted (e.g. meters on National Park Service property are maintained and owned by the National Park Service).

A Planned Unit Development (PUD) is a large-scale development in which conventional zoning standards (such as setbacks and height limits) are relaxed in order to conserve sensitive areas, promote the creation of public amenities such as parks and plazas, and encourage the mixing of different land uses.

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.

This dataset contains Historic Landmarks (by structure) officially designated by the District of Columbia. This is a consolidated collection of structures with historical significance within the District of Columbia as listed in the "District of Columbia Inventory of Historic Sights". It contains the SITES and attributes of buildings, statues, bridges, forts, fountains, & memorials of historical worth. These sites in general are the lot or lots that a structure or other designation sits on.

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.

Data source is the Office of Tax and Revenue’s Computer-Assisted Mass Appraisal (CAMA) system. The CAMA system is used by the Assessment Division (AD) within the Real Property Tax Administration to value real estate for ad valorem real property tax purposes. The intent of this data is to provide a sale history for active properties listed among the District of Columbia’s real property tax assessment roll. This data is updated daily. The AD constantly maintains sale data, adding new data and updating existing data. Daily updates represent a “snapshot” at the time the data was extracted from the CAMA system, and data is always subject to change.
