4S Ranch is a locale of San Diego County, California. It is located about 25 miles north of downtown San Diego and 13 miles east of the Pacific Ocean in the North County Inland area of San Diego. To the east of 4S Ranch is the San Diego community of Rancho Bernardo. To the west is the Santa Fe Valley, which includes Rancho Santa Fe. Lake Hodges forms the northern border of the community while Black Mountain Ranch, which includes Del Sur and Santaluz, and Rancho Peñasquitos are both situated to the south. The ZIP Code is 92127, and the community is inside area code 858.
The origin of the name 4S Ranch is not specifically known. The first recorded owner of Rancho San Bernardo, as the area in which 4S Ranch is currently located and originally part of 4 separate sitios or square leagues, was acquired by an English sea captain named Joseph Snook "Captain Snook" (who later became a Mexican citizen and changed his name to Jose Francisco Snook) in 1842 and 1845 through land grants from the Mexican Governor of California. Many now believe the "S" in 4S Ranch stands for "Snook". The "4" may stand for "4 Snooks", after Snook and his three brothers or the 4 sitios or leagues granted to Snook. Contrary to myth, Snook and his wife never had any children. After his death, Snook's heirs sold the property to James McCoy for $4,020.
Between 1847 and the turn of the century, the site of 4S Ranch was used extensively for the grazing of both sheep and longhorn cattle. By 1915 4S Ranch had been obtained by the San Dieguito Mutual Water Company, a subsidiary of Santa Fe Railroad. The railroad erroneously believed that eucalyptus trees would make excellent railroad ties and planted thousands of them. This was unsuccessful and 4S Ranch was sold numerous times before being purchased by Albert E. Smith. In 1928, Albert Smith built the Spanish mission style house on a ridge overlooking Lake Hodges. This house remains today. Soon after, the property was acquired by William A. Clark, founder of the Los Angeles Philharmonic Orchestra. After Clark died in 1938, his widow sold 4S Ranch to Albert G. Ralphs of the Ralphs family, owners of the southern California grocery chain. 4S Ranch was primarily used by the Ralphs family for recreational and farming purposes until crop yields fell. Grass fires in 1944 and 1981 burned large portions of the original eucalyptus and citrus groves. 
In the early 1980s, the Ralphs family agreed to develop the southern portion of their property (what is now the 4S Ranch master planned community by Newland Communities) and retain the northern 1,200 acres (4.9 km2) as a family retreat which had been operated as a working ranch for 50 years. In the 1980s the third generation of the Ralphs family was granted stewardship of 4S Ranch. Albert's grandson and granddaughter Bob Ralphs and Linda Ralphs spearheaded the family's efforts to develop the property since 1979. They received approval in 1984 from the county to develop 634 acres of the property, with the rest set aside for development at least until after 1992. A portion of 4S Ranch was within a Williamson Act Agricultural Preserve until the contract expired at the end of 1992. The development plans began in general for a $100-million first phase of development at 4S Ranch business park component that totaled 180 acres, enough for about 3 million square feet of research and light-industrial space.
Development began in 1987 that was primarily a business park. Housing development began in the early 2000s and was completed in 2014. At least 4,700 homes spread over 2,900 acres make up the community. Of the remaining 1,184 acres owned by the Ralphs family in the most northerly area of 4S Ranch, approximately 90 percent is designated natural open space with a potential 11 single family homes to be built on large estates accessible via Ralphs Ranch Road. 
4S Ranch is underlain by Jurassic Santiago Peak Volcanics, Tertiary Stadium conglomerate, and slope wash alluvium. The land of 4S Ranch pre-development consisted of a variety of landforms ranging from nearly flat-lying mesas and gently rolling hills to rugged, steeply-sloping hillside terrain. Elevations range from about 300 to 1,150 feet above mean sea level. 1,600 acres of open space exceeded the mitigation requirement by 1,100 acres, and the loss of 3.8 acres of wetland habitat is mitigated by the creation of 9 acres of high quality wetland habitat.
4S Ranch is anchored by a bustling retail area surrounding the intersection of Dove Canyon and Camino del Norte that is composed of three main sections: the 4S Ranch Village Center, 4S Commons Town Center and the 4S Health Center. The 4S Ranch Village Center includes the area's only gas station, veterinary care, restaurants, salons, and a Starbucks. 4S Commons Town Center has two grocery stores, restaurants, shopping and services, such as dry cleaning and shipping. The 4S Health Center is home to a variety of medical specialties including family medicine, oncology, pediatric dentistry, women's health, oral surgery, and facial plastic surgery.
