Architectural Design Review Board (ADRB).

Certificate of Appropriateness.

Any exterior work to any structures located within one of the City of Hamilton's Historic Areas or properties individually listed by Ordinance requires a Certificate of Appropriateness (COA) from the Architectural Design Review Board (ADRB).

Like-for-like work (such as painting a house the same color it currently is) and many minor changes (such as replacing a roof with a similar roof color) is an administrative COA that is no cost and can usually be completed within two business days. More substantial exterior work requires a hearing before the Architectural Design Review Board. Applications and plans are submitted to the Planning Department.

Agenda & Minutes

Previous Agendas are located on the Agenda & Minutes page.

The ADRB Policies and Guidelines provide guidance on a wide variety of common projects and discourage certain types of exterior alterations. Applications for projects such as demolition, replacing historic windows, adding vinyl siding, and removing box gutters are considered projects that could detract from the historic and/or architectural character of a building and will require documented evidence and reasoning for the proposal. Please review the Policies and Guidelines before starting any project on a building in a historic district or designated historic property.

The Planning Department is available and happy to answer any questions you have about applying for a COA and can be reached at 513-785-7350 or hamiltonhistoric@hamilton-oh.gov.
