Record Lots (Historical)

A history of Record Lots 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 include: 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.本数据集收录由建筑物部（Department of Buildings, DOB）-测量员办公室（Office of the Surveyor, OS）——哥伦比亚特区测量员（DC Surveyor）所定义的记录宗地（Record Lots）历史信息。此类宗地为哥伦比亚特区测量员办公室依据《哥伦比亚特区分区条例》（需具备公共街道临街面等要求）完成测绘并登记的官方合法细分宗地。通常情况下，此类宗地的编号范围为1至799，且同一地籍街区（Square）内不会重复使用同一编号。该编号规则存在两类例外情形：其一，当某一地籍街区内1至799的编号资源耗尽时，测量员办公室将启用1200及以上的编号，甚至会使用8000及以上的编号；其二，出于不明原因，另有42个地籍街区的记录宗地编号介于799至1200之间。
