To the extent that any unit or common element encroaches on any other unit or common element, whether by reason of any deviation from the plats and plans in the construction, repair, renovation, restoration, or replacement of any improvement or by reason of the settling or shifting of any land or improvement, a valid easement for such encroachment shall exist. The purpose of this section is to protect the unit owners, except in cases of willful and intentional misconduct by them or their agents or employees, and not to relieve the declarant or any contractor, subcontractor, or materialman of any liability which any of them may have by reason of any failure to adhere strictly to the plats and plans.
