Ohio Rev. Code § 519.171: Architectural review board authorized - standards and procedures.

The board of township trustees may create an architectural review board to enforce compliance with any zoning standards it may adopt pertaining to landscaping or architectural elements. The board of township trustees shall adopt the standards and procedures for the architectural review board to use in reviewing zoning permit applications for compliance with those landscaping or architectural standards. If the board of township trustees does not create an architectural review board, it may delegate this enforcement authority to the zoning inspector or the zoning commission.

An architectural review board shall consist of no more than five residents of the unincorporated territory of the township. At least one member shall be a licensed architect or engineer; if a licensed architect or engineer does not reside in the unincorporated territory of the township, that member of the architectural review board may be a resident of the county.
