Sanitz is mentioned in the sources in 1256 when it was called Kirchdorf. The mention involved the church at Dänschenburg which was described as a daughter church of Sanitz. A subsequent mention occurs in an agreement of 2 June 1291 involving Henry I of Mecklenburg-Güstrow, at the time the local Bishop, who granted the lordship of the Rostock region to his ward Nicholas whose own heirs would retain these privileges. In the fourteenth century Sanitz is recorded as having been held by asuccession of vassals such as Bernard Kopmann from Rostock, the knight Siegfried of Plön, Reimar von Wedel, the Rostock council member Dietrich Horn, along with his son, the major Dippold Horn. After this the village was inherited by the Cistercian monastery at Doberan who held it until the Reformation. In 1552 the monastery fell victim to a programme of Secularization in the area and the village was transferred as a ducal domain to Robnitz and thereafter leased out to various land owning families. In 1879 the village passed into the control of nearby Toitenwinkel.
