(Distinguishing Weseloh Family Limited Partnership v. K.L. Wessel Construction Co., Inc. (2004) 125 Cal.App.4th 152, this decision holds that a soils engineer which was hired by a construction contractor to plan the foundation for an addition to a family home owes a duty of care to the owner of the property even though not in contractual privity with the owner. Weseloh involved a commercial property, not a home. And here the soils engineer knew his plans were for the owner’s benefit, and his plans were followed with bad results. The trial court erred in granting the soils engineer summary judgment on the owner’s negligence claim and also on a nuisance claim, especially since duty of care was not an element of the nuisance claim.)
