Land Division Reviews

A Land Division Review is required to divide an existing property to create additional lots, parcels or tracts. A land division may also be required to legalize a lot that was created outside of the legal process (such as through deed). Read more about standard land division reviews.

All land divisions require two steps:

   1. Review and approval of the preliminary plan

   2. Review and approval of the final plat

  • To begin the land division process you may submit for an Early Assistance appointment. These optional appointments are available for feedback on your land division prior to submittal of the land use review application.
  • In addition, pre-application conferences are required for Type III Land Divisions prior to submittal of the land use review application.
  • Following approval of the preliminary plan, the applicant must submit a final plat for review and approval. The final plat shows the final surveyed layout of the land division, including all lots, tracts, easements and rights-of-way.
  • Once the final plat is recorded, building permits can be submitted for the newly created lots.

Other reviews

  • A Property Line Adjustment allows for minor changes to the location of existing property lines between existing legal lots.
  • A Replat allows for removing and reconfiguring existing lot lines within a site, resulting in up to three lots.
  • A land division may be combined with a Planned Development Review.
  • Some situations may qualify for a Middle Housing Land Division, an expedited process with limited approval standards.
  • A final plat review is required to complete the land division process.
