Layer name: PARCEL
Subject category: property
Title: Parcel
Feature Count: 0
Feature Type: Polygon
Abstract: This layer represents the tax parcels in King County. This layer also includes place-holder polygons which do not represent tax parcels but are included to identify platted and unplatted land descriptions. The layer includes stacked polygon geometry for undivided interest and vertical parcels. King County parcel numbers may include leading zeros in PIN, Major or Minor. The data is created for Assessment purposes and is not guaranteed to represent accurate measurements or to reflect salability or buildability of a tax parcel. These tax parcel boundaries represent general location only, and they should not be considered or used as the exact legal parcel boundary location. Do not use for survey purposes.
Purpose: The purpose of the tax parcel layer is to assist users in locating property within King County. The layer serves as the parcel framework data layer for King County.

Supplemental Information: Rights of Way (ROW) polygons are not included in the Tax Parcel layer. ROWs can be found in a separate layer called ROW. Items PIN, MAJOR, MINOR, are present in both the geodatabase feature class and shapefile. The fields are described as a text fields because PIN, MAJOR and MINOR may have leading zeros. PIN = MAJOR + MINOR. When joining to Assessor tabular data the user may need to manipulate the tabular data to create PIN from Major + Minor fields. PIN is not unique through time and may be reused when property is segretated. Placeholder polygons that don't represent tax parcels are coded with MINOR as follows: HYDR = Water, UNKN = Unknown , TRCT or Txxx = Tract with or without undivided interest, PUBL = Public ownership no tax parcel number. Condominiums are represented by a single polygon for the complex. MINORs for condo complexes are '0000'. Individual condo units are stored in the Assessor tabular data files and can be joined to the parcel layer by the MAJOR number field. Undivided Interest and Vertical parcels may be represented by stacked polygon geometry. One example of stacked polygon geometry for an Undivided Interest can be found in PIN = 4088801605. Multiple polygons exist at this location each with uniqure PINs.

Attribute Information

_MAJOR_First six characters of the parcel identification number (PIN). May have leading zeros.Six character code derived from PLSS or plat number. eg 092503 for section 9 in township 25, range 3. There is some overlap with PLSS and Plat numbers.
_MINOR_Last four characters of the parcel identification number (PIN). May have leading zeros. Place holder minors may include: HYDR = Water , UNKN = Unknown, TRCT or Txxx = Tract with or without undivided interest. May not always start with T, PUBL = Public ownership no tax parcel number. MINORs for condo complexes are '0000' Minor numbers starting with 9 generally signify unplatted parcels.
_PIN_Parcel Identification Number. Major+Minor. May have leading zeros.Ten character concatenation of the Major and Minor field.
