lien rights, the claimant shall send to the last-known address of

the original contractor and an owner of the property a pre-lien

notice pursuant to the provisions of this section. Provided

an owner shall be valid unless the pre-lien notice provided in this

section was sent within seventy-five (75) days of the last

furnishing of materials, services, labor or equipment by the

claimant.

subparagraph, the term “residential” shall mean a

single family or multifamily project of four or fewer

dwelling units, none of which are occupied by an

owner, or
