Rarely does a property of such historic distinction come to market in the Covenant. Designed in 1954 by Master Architect Edgar V. Ullrich, this Modern Custom Ranch residence embodies classic California living within a peaceful, rural setting — beautifully preserved, meticulously restored, and protected under the Mills Act, offering potential property tax advantages. Situated on 2.72 usable acres, the 1,943 sq ft single-level main residence includes three bedrooms, all thoughtfully arranged on one level. Restored in 2014 and maintained in excellent condition, the property also features a 1,197 sq ft guest house converted from a historic barn, offering two bedrooms, a great room, and a full bath. The residence and its accessory buildings are listed on the San Diego County Historic Landmark Register, underscoring their architectural significance and heritage value. The grounds are equally compelling, featuring a beautifully maintained garden and backyard, along with two enclosed pastures, enhancing the property’s authentic ranch character and usability. An adjacent 2.89-acre parcel is available exclusively in conjunction with the purchase of the primary 2.72-acre property and will not be sold separately. Total offering price for both parcels: $8,700,000. This property is a well-preserved, architect-designed Modern Custom Ranch estate that embodies the original vision of Rancho Santa Fe—combining architecture, land, and lifestyle into a cohesive historic environment. A rare opportunity to own a meaningful and enduring piece of Rancho Santa Fe history.
