Parcels - Regional

• Pima County GIS parcel maps show "seamless" parcels. That is, they have been stretched or "rubber-sheeted" where necessary to ensure connectivity between subdivisions and sections. The intent is to accurately display parcel and street relationships with minimal sacrifice of dimensional accuracy. The resulting maps are good for planning, overlaying other map features, and seeing the relationships between parcels

• Property Use Code (a.k.a. Landuse Code, Land Use Code, USE)
  • The Arizona Department of Revenue Property Use Code Manual explains the content and meaning of the PARCEL_USE field (previously named just "USE") Property Use Code values. See the Legislative Class Codes in PAREGION document link below to understand the relationship between the PARCEL_USE field and the LANDCLASS and IMPCLASS fields.

  • The Pima County Assessor has a Reference Data section in their Downloads area that includes a UCodes.zip file containing their Ucodes.csv file. The Ucodes.csv file is a list of 4-digit Use Code values (without leading zeros) with Secondary Type and Primary Type Definitions. You may find this simple list easier to work with than the Property Use Code Manual.

    CSV (Comma Separated Values) files, sometimes called comma delimited files, are a common interchange format between software programs. The files may open automatically in your web browser. Or, the files can be saved and imported into programs such as Access, Excel, Word, dBASE or other software than understands CSV format.
