The requirement for notice to the tenant of a condominium conversion is found in General Statutes 47-88b (b). On September 29, 1979, and prior to October 1, 1979, this provision required only sixty days' notice of the intended condominium conversion. This notice is required to be "hand delivered" or sent by "certified mail, return receipt requested." This statute was amended, as of October 1, 1979, by Public Acts 1979, No. 79-622, to require one hundred and eighty days' notice of the conversion. If the plaintiff's notice to the defendant was adequate, he would have come within the former provision, requiring only sixty days' notice. The issue is whether the term "hand delivered" requires delivery to be made personally to each tenant. We agree with the trial court that it does.
