Real Estate: The D.C. Recorder of Deeds (202-727-5374) keeps the D. C. Land Records. You can look up property owners, tax and sales data back to January 4, 1999 using the District's Real Property Sales Database. For older records, use a commercial service such as Accurint, KnowX or Lexis. You can retrieve images of deeds an other land records back to January 1, 1973 using the DC Online Public Records.

Condominiums: Condominiums are required to file Public Offering Statements with the the Rental Coverage and Sale Division (202-442-9505) of the Department of Housing and Community Development under § 42-1904 of the D.C. Code. Note: I called the Division in August, 2010 and was told that the rules referenced in § 42-1904.07 have not been issued and the Division does not require an annual update report unless there is a change to the condominium documents.
Similarly, the D.C. Department of Consumer and Regulatory Affairs is authorized to write regulations concerning a condominium's warranty against structural defects under § 42-1904.07 of the D.C. Code. Regulations were proposed in 2002/3 and 2007 but did not become law. Legislation to enact the regulations was introduced in the City Council in 2006 and 2007 but not passed.
