Property Boundary Change Information

Information on permits to change the boundaries of a piece of property

Overview

Property boundary change permits are required for property modifications including the following:

  • Subdivisions – Splitting one property into two or more new properties
  • Lot Consolidations – Combining two or more adjacent properties into one property
  • Boundary Adjustments – Relocating the property line(s) between two or more adjacent properties

 

Permit Submission Process

Preparation

The applicant must provide proof of payment of the previous year's real estate taxes for all properties involved. Tax receipts can be obtained from the Collector of Revenue's office.

The real estate taxes must be paid for the previous year throughout the application process. Example: for an application initiated in December 2020 and completed in January 2021, the real estate taxes would have to be paid for 2019 and 2020.

The City Assessor's Office has an interactive property search tool detailing property information and tax delinquencies.

Subdividing a property in which a building would be located along the proposed boundary (i.e. a townhome) requires a Townhome Fee Simple Conversion Permit from the Department of Public Safety - Building Division prior to subdivision approval. Inquiries may be directed to:
