Lot Validation (LV)

Lots that were created before the zoning ordinance was enacted or were created by recordation of a plat or deed without county approval may be “validated” by the county. If the legality of a lot is unclear, a lot validation can determine whether the lot meets certain requirements and can be validated so that a building permit may then be issued for the development of that lot. County Code Sections 101-1-12, 101-1-13, and 101-1-14 describe the process for validating a lot. Once the review is complete, the county will issue a written determination as to whether a land parcel is a valid lot or unbuildable outlot.

Additionally, The Department of Tax Administration (DTA) allows for an administrative process to consolidate tax map numbers to receive one tax bill. The process, known as a lot split, requires the request be submitted through PLUS and routed to DTA and the zoning permits branch for approval.

This information is the most common for how to obtain the necessary approval for your project and is not representative of all the conditions you may encounter.

 

WHO SHOULD APPLY?

Property owners or their duly authorized agents may submit lot validation applications.

  • Zoning Information
  • Design Codes and Standards
  • Do I Need to Hire a Design Professional?
  • Floodplains
  • Resource Protection Areas (RPA)
  • Grading/Site Plans
  • Parking Tabulation
  • Types of Soils and Problem Soils
  • Researching Site Conditions

Review Process

Staff from the Site Application Center and Site Development and Inspections Division will review your package for completeness and compliance with submission requirements. Lot Validations are also reviewed by the County Surveyor’s Office, and the Department of Planning and Development. Once the review is complete, staff will issue a determination as to whether the requested lot is a validated lot (e.g., a building permit may be issued for work on the lot) or an outlot (no building permit may be issued on the lot).

Issuance of Determination

Once all reviews are approved and fees have been paid, your lot validation determination will be available to download from PLUS.
