We understand the notice requirements where we are the Prime, and where we act as a subcontractor. However, where we are working for a homebuilder, please advise the requirements. We are not sure how to notice the homeowner [where there the home is being constructed, and therefore, not sold]. However, if the builder sells the house while we are completing work, may be too late to file a lien as the new homeowner would have gained title, and possible loan without the lien coming up in a title search. Do we file the lien before construction starts? Then issue a release of lien?
