(3) A copy of the petition and the notice of the hearing on the petition shall be given to the owner of the mobile manufactured home, the municipality and all lienholders who have recorded a lien against the mobile manufactured home or of whom the owner of the mobile manufactured home park has actual knowledge. Notice to the municipality and to lienholders shall be by certified mail. Notice to the owner of the mobile manufactured home shall be designed to maximize the likelihood that the owner will receive actual notice of the petition, without regard to whether the owner appeared in the summary process action. Such notice to the owner of the mobile manufactured home shall be conspicuously posted at the entrance to the mobile manufactured home and also sent by certified or registered mail, return receipt requested, to the owner of the mobile manufactured home and to the attorney, if any, who appeared for such owner in the summary process action. Notice to the owner of the mobile manufactured home shall be sent to such owner at the owner's last-known address and also to such owner in care of any other person reasonably believed to know the location of the owner. The court may require supplemental notice if it finds that additional notice is likely to result in actual notice to the owner of the mobile manufactured home.
