Drawing residents that are primarily business executives and professionals, Hillsborough has traditionally served as a haven for San Francisco's upper echelon that desire a more relaxed, rural living pace. By World War II, most of the sprawling estates had been parceled into smaller lots still generous acreage by San Francisco standards. Residents have staunchly fought to preserve the residential nature of their community despite the area's allure for major developments such as the $315 million research center. Zoning laws have been consistently and rigidly enforced to offer residents serenity in this residential haven. Since 1937, the minimum lot size has remained a half-acre with a minimum frontage of 150 feet. Beyond the beauty and natural tranquility of its surroundings, one of the primary attractions to Hillsborough is its superb school system that has been recognized by the county, state, nation - even internationally - for excellence in education.
