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.记录宗地（Record Lots）由建筑局（Department of Buildings，DOB）下属的测量师办公室（Office of the Surveyor，OS）——哥伦比亚特区测量师办公室（DC Surveyor）定义。此类宗地为哥伦比亚特区测量师办公室依据《哥伦比亚特区分区条例（Subdivision Ordinance of the District of Columbia）》创建的经测绘归档的官方登记细分宗地，需满足公共道路临街等相关要求。通常情况下，此类宗地的编号范围为1至799，且在单个街区内同一编号不会重复使用。该规则存在两类例外：其一，当单个街区内1至799的编号范围用尽时，测量师办公室将启用1200及以上的编号，甚至可使用8000及以上的编号；其二，存在不明原因的特殊情况：共有42个街区的记录宗地编号大于799且小于1200。
