In 1901 Detroit Iron Works built two iron-making blast furnaces on Zug Island, near Delray. The city of Delray Beach, Florida, in Greater Miami was named after Delray in 1901. In 1906 Detroit annexed Delray. Chemical plants and factories opened in Delray. As years passed, residents who were able moved to larger homes in less industrial neighborhoods. As the value of the housing stock declined, absentee owners did not spend on renovation and tenants did not repair their damage thus leading to continued falling values and a desire of tenants to rent rather than own.
