Record Lots

Record Lots are defined by the Department of Buildings (DOB) – Office of the Surveyor (OS) - DC Surveyor. They are official, platted, recorded subdivision lots created by the D.C Surveyor’s Office in compliance with the Subdivision Ordinance of the District of Columbia (must have public street frontage, etc.). Typically, these lots are numbered 1 through 799 with no number being used more than once in a Square. Exceptions to this rule: when the 1-799 range has been exhausted within a square, the Surveyor’s Office assigns numbers from 1200 or may even use 8000 and above; and for reasons unknown, 42 Squares have record lot numbers greater than 799 but less than 1200.
