Colleen Kilner, in her book "Joseph Sears and his Kenilworth", stated that lots were sold to Caucasians only. However, she does not provide evidence for this claim or document its origins. While the original ordinances for the Village specify strict building regulations, they do not include the restriction of sales based on race or religion. The village population on reached 2,501 in 1930 and has stayed nearly the same since then. In 1949, the US Supreme Court ruled, in Shelley v. Kraemer, that restrictive covenants were unenforceable. In addition, the Civil Rights Act of 1968 outlawed such racial and religious covenants, but many, though unenforceable, are still found in housing deeds in the 21st century.
