Ohio Revised Code Title LIII. Real Property § 5301.86

(A) An interest that has priority under other law is not affected by an environmental covenant unless the person that owns the interest agrees to subordinate that interest to the environmental covenant.

(B) Sections 5301.80 to 5301.92 of the Revised Code do not require a person that owns a prior interest to subordinate that interest to an environmental covenant or to agree to be bound by the covenant.

(C) A subordination agreement may be contained in an environmental covenant or in a separate record. If the environmental covenant covers commonly owned property in a common interest community, the record may be signed by any person who is authorized by the common interest community.

(D) An agreement by a person to subordinate a prior interest to an environmental covenant affects the priority of that persons's interest, but does not by itself impose any affirmative obligation on the person with respect to the environmental covenant.
