All construction projects in Suffolk County are governed by Massachusetts state law (MA Gen. Laws ch. 254, §§ 1 et seq.). There isn't a separate Suffolk County lien law — the state rules apply uniformly. What is local is where you record: in Massachusetts you file the lien with the Registry of Deeds for Suffolk County — or the equivalent local recording office.
