Division of Land

A division of land means a subdivision, short subdivision or large lot subdivision. 

  • Read the code (See chapter numbers below to get to the correct section of the code.)
    • General provisions regulating the division of land (Chapter 18.04)
    • Short Plat (Chapter 18.32) - Division of land into 4 or fewer lots, any one of which is less than 5 acres
    • Large Lot (Chapter 18.28) - Division of land into 2 or more lots, all of which are 5 acres or larger and one one of which is smaller than 40 acres.
    • Olympia Urban Growth Area - see Title 23
    • Plat (Chapter 18.12) - Division of land into 5 or more lots, any of which is smaller than 5 acres.

Boundary Line Adjustment

A Boundary Line Adjustment (BLA) is a reconfiguration of property lines between two or more separate legal parcels.  BLAs are not subdivisions and cannot create new parcels or building sites. Another form of BLA is a "Lot Consolidation."  A Lot Consolidation is used to combined two existing parcels.  Lot Consolidations erase parcel lines so that only one parcel remains.
