Need Assistance?

If you do not have access to a computer or mobile device or if you need assistance, the GIS Team will be happy to help you with your application.

Note: The GIS Division is responsible for the assignment of new addresses and the maintenance of the Town's master address database.

New Addresses

When construction of any new development is proposed, a request for address assignment is required. New addresses are assigned consistent with the existing addresses and the Town Addressing Standards and Regulations. Addresses are not assigned to vacant land when no work is proposed.

It is required to submit an address request prior to the issuance of any permits. The GIS Division will determine and assign valid address(es) in accordance with town regulations. 

Once addresses are assigned, an addressing notice is prepared and sent to our distribution list, which includes the post office, town departments, and emergency services.

New Address Submittal Requirements:

NOTE: Address Requests must be completed by the property owner, or his/her legal representative. A tenant cannot sign for a property owner.
  • Complete the Address Request form in OpenGov, including submitting the following documents:
    • Site plan showing the property lines, building footprint and entrance to the building.
    • Floor plans are required for changes in suite or unit numbering.
    • Based on the scope of work, other supporting documents may be required.
  • After completing the application in the OpenGov Portal (linked above), the Building Department, Planning, Zoning, and Natural Resource Department, Fire Department and Police Department (when necessary) will review the application and provide their signatures.

Failure to apply for the Address Request application may delay the issuance of Building Permit.

Change Existing Address

Because so many agencies and service providers are affected, we do not change existing address numbers based on perceived benefits or cultural preferences.

Existing address numbers can only be changed for the following reasons:

  • The existing address number is out of sequence with the adjacent addresses.
  • Entry change on a corner lot with building permits for a remodel.
  • You have documented difficulty receiving emergency services or mail delivery.

Limitations:

  • Addresses are not assigned to empty lots or vacant land.

Addresses will only be assigned when new development or alteration work is proposed.
