SurDocs, commonly known as Surveyor Document System, is the District of Columbia's Department of Buildings (DOB) land records management system. DOB's Office of the Surveyor maintains the legal records of all land plats and subdivisions of private and District government property within the District of Columbia. The existing records cover a period of more than two centuries.

SurDocs is an online research tool that enables the public to search all digital land surveys. This tool is used to view all field survey records and surveyor plats.

The Quick Search and the Advanced Search are two types of searches conducted in the system. The Quick Search option allows anyone looking for information about a certain lot to search the system for that information. The Advanced Search option uses Book and Page references to access Surveyor's Office records.
