§ 30.29 LIEN OF SPECIAL ASSESSMENT.
   Special assessments and all interest, penalties and charges thereon from the date of confirmation of the roll be and remain a lien upon the property assessed of the same character and effect as a lien created by general law for state and county taxes or by the Village Charter for village taxes until paid. The failure of the owner to receive any notice required to be sent under this subchapter shall not invalidate any special assessment or any special assessment roll if such notice was in fact published and mailed as herein provided. Any failure to give notice as required in this subchapter shall not invalidate an entire assessment roll. In no case shall any special assessment be declared invalid as to any property if the owner or party in interest thereof has actually received notice, has waived notice or has paid any part of the assessment.
