Yes. In states that have NOC requirements it’s common that an “Owner’s Designee” can be appointed in the NOC itself. This is specifically allowed in Ohio, as part of the information to be included on the NOC is “[t]he name and address of the owner’s, part owner’s, or lessee’s designee, if any.”
In general terms, a designee is a party chosen by the owner or lessee to receive notice on their behalf. While the appointment of a designee can decrease the paperwork burden on the property owner, and can help the owner or lessee manage the receipt of notice documents it’s important to make sure any designee chosen is up to the task. Since the property owner is the party who would ultimately be wrapped up in any potential lien claim arising on the project, s/he may want to receive notices of furnishing personally in order to get insight into the identity of the project participants and exert some control over the payment process.
