Exterior Changes
Are you planning to make modifications to a contributing structure in Old Town?
Similar to new construction in Old Town, exterior modifications to contributing structures require a Certificate of Appropriateness from the Historic Preservation Commission.

To learn whether a property is identified as Contributing, see the GIS page.

What kind of exterior modifications require a Certificate of Appropriateness?
Exterior changes requiring a COA include, but are not limited to:

  • doors
  • windows
  • window shutters
  • awnings
  • railings
  • porches and decks
  • building materials
  • roof materials
  • additions

What kind of exterior modifications can be made without a COA?
Changes that do not require HPC approval include:

  • Exterior changes to non-contributing structures
  • Small, minor building or construction not visible to the public eye
  • Fences meeting pre-approved material and height specifications on properties within the OT-3 district
  • Temporary construction trailers for the use of on-site material storage during construction
  • Changes in paint color. Click here for a list of historically appropriate colors.
  • Ordinary maintenance and repair that does not involve changes in dimension, material, configuration, or outward appearance
  • Work that is required for a property to come into compliance with federal and state laws pertaining to persons with disabilities

How do I obtain a Certificate of Appropriateness?
All applications and fees can be found on the planning applications page. Please contact the planning division with any questions, or when you are ready to submit.

Meetings occur monthly, and complete applications are due no later than one week prior to the meeting.

Projects are subject to both the SmartCode and the Architectural Design Standards.

What if I need to make changes to an approved plan?
It is imperative that any work done matches approved plans precisely. Any desired changes or modifications to the approved plans require HPC re-review prior to the change being made. Any changes made without an amended COA are considered violations of City code. Structures that do not match the approved plans will not pass required inspections and will remain in violation until the issue is addressed.

If unforeseen circumstances require that your approved plans be modified in any way, contact Planning staff immediately to be placed on an upcoming agenda. Do not proceed with the changes without an amended COA.
