The DC government provides several online resources for researching land and property information in the District of Columbia.

Government Properties

The Department of Real Estate Services (DRES) maintains an online government property inventory of all properties owned or controlled by the District government.  Users can search by address, browse by area, or locate by map.  The inventory includes square feet, property type, existing use, future use, the government department that controls the property, and the owner.

Tax Records, Square Feet and Use Codes

The Office of Tax and Revenue's (OTR) real property tax database provides online access to real property information, including but not limited to: property value, owner's name and address, the property's square feet, and use code.  Users can also do a search by address to obtain the square, suffix, and lot.

Land Records and Deeds

The Recorder of Deeds maintains the District's land records.  Users can search for deeds, many leases, and easements.  Tax forms and publications are also available for download.  There are forms for deeds, recordation and transfer taxes, liens, exemptions, condominiums, and foreclosures.

Vacant Properties

The Department of Consumer and Regulatory Affairs (DCRA) maintains a list of vacant properties in the District of Columbia.  Vacant properties are taxed at a higher rate if they do not qualify for an exemption.  More information is available on the Office of Tax and Revenue (OTR) vacant property webpage.

Zoning Regulations and Maps

The DC Office of Zoning (DCOZ) maintains the District's Zoning Maps.  All construction or rehabilitation on private land must conform to the requirements imposed by the Zoning Regulations and Zoning Maps adopted by the DC Zoning Commission.  These requirements include land use, density, height, and bulk characteristics.  More information is available on the DCOZ website.
