Ohio Rev. Code § 1311.08
Where an improvement consists of two or more buildings united together, situated on the same lot or upon contiguous or adjacent lots, or of separate buildings upon contiguous or adjacent lots, or where work or labor has been performed or material has been furnished for improvements which are located on separate tracts or parcels of land but operated as an entire plant or concern, and erected under one general contract, the lien for the labor or work performed or material furnished attaches to all such improvements, together with the land upon, around, or in front of which such labor or work is performed or material is furnished, the same as provided in sections 1311.02 and 1311.03 of the Revised Code in case of a single improvement, and it is not necessary to file a separate lien for each improvement.
Provided that where a lien attaches pursuant to this chapter to contiguous or adjacent lots, on which lots separate dwelling units designed to be separately sold have been or are being constructed, except with respect to any person who performs labor or work or furnishes material for the construction, alteration, or repair of any street, turnpike, road, sidewalk, way, drain, ditch, or sewer by virtue of a private contract between him and the owner, part owner, or lessee of lands upon which the same may be constructed, altered, or repaired, or of lands abutting thereon, the lien rights on any lot on which all construction has been completed and which has been conveyed to a purchaser for value shall terminate either sixty days from the date on which the last labor or work was performed or material furnished in connection with the construction on any of such lots, or sixty days after the instrument of conveyance to the purchaser separating the lot from the contiguous or adjacent lots is filed for record, whichever date is earlier, unless and except for lien rights which are evidenced by an affidavit or affidavits filed for record in accordance with section 1311.06 of the Revised Code before the expiration of the sixty-day period.
