In 1927, the Rancho Santa Fe Association was founded as a nonprofit homeowners' association. It enforces the Prospective Covenant, adopted in 1927. This far reaching document requires the Association to preserve the rural character of the community and its natural landscape, and to uphold the quality of architectural and land improvement. The protective Covenant also requires the Association to maintain the health, safety and general welfare of its members.

In addition to its regulatory duties, the Association operates and maintains the golf course, tennis club, playing fields, and riding and hiking trails for the benefit of its members.
