Types of Applications

Certificate of Alteration


A Certificate of Alteration is required prior to work or projects impacting the exterior appearance of any designated local landmark or any property located within a historic district. This includes new construction, demolition, and alterations to historic structures. Examples include replacing historic windows on a property, adding an addition to a historic property, or constructing a new building on a vacant lot within a historic district.

Ordinary Maintenance and Repair

Minor alterations to historic landmarks and historic district properties may qualify for administrative review, meaning that the application does not require a public hearing and the applicant does not have to appear before the Historic Landmark Commission. Examples of projects that qualify include replacing of in-kind materials, minor alterations to non-contributing structures, replacing rotted or worn architectural materials. 

Historic Landmark Designation

If you are interested in designating your property as a historic landmark, an application for landmark designation must be reviewed by the Historic Landmark Commission. Generally, a building must be at least 50 years old to qualify as a historic landmark. Staff is able to assist you with researching the history of your property. There are a number of financial incentives available should your property be designated as historic. 

Tax Relief Application

Any property that has been designated a historic landmark, or is located within a historic district, is eligible to apply for relief in property taxes for a period of 5 years, with a maximum allowance of 10 years. In order to qualify for tax relief, improvements must be done to the property and amount to at least 10% of the value of the property as reflected on county tax rolls. Applications should be submitted prior to the first of July for which year the relief would be granted.
