In 1909, Frederick E. Bryant—a British agriculturalist—Harold J. Bryant, and William Greenwood of the Palm Beach Farms Company in Colorado, bought thousands of acres of land in the Everglades and later along the coast of Lake Worth in 1910.

The men sold the land to buyers throughout the United States and Canada, offering 5 acres (2.0 ha) plots for $250, with a $10 down payment and a $10 per month charge, which also included a 25 by 25 ft (7.6 by 7.6 m) parcel on the shore of Lake Worth.

Around that time, Lawrence Carter "L. C." Swain of Massachusetts acquired 320 acres (130 ha) of land, with the intention of creating a community for the working class.

[8] In September of that year, a hurricane destroyed the civic building and community hall, but did not cause much other significant damage.

[9] Two years later, Greenacres City was devastated by the 1928 Okeechobee hurricane,[1] which damaged "practically every building" substantially, according to The Lake Worth Herald.

Then-Mayor Charles A. Grabowski actively fought the new law, as no referendum to forfeit the town's charter had been held.

[11] Additionally, Grabowski accused a resident of starting the dissolution movement out of spite after being denied a homestead exemption and claimed that many of the signatories did not actually own property in Greenacres City.

Grabowski also asserted that the pleas of city officials and a large number of residents in favor of remaining a town were ignored.

Over the subsequent decades, Greenacres City eventually expanded to 6 sq mi (16 km2) through annexation.

[1] In the 1960s, a city hall complex was constructed at the intersection of Perry Avenue and Fourth Street, while a community center was built nearby.

In response to concerns about future growth, residents approved a bond referendum in 1984 to fund construction of a new city hall, a public safety complex, and recreational facilities.

[13] On November 6, 1990, about 60% of voters chose to drop the word "city" from the official name, thus renaming the municipality Greenacres.

[13] To commemorate the city's 80th anniversary, the Greenacres Historical Society was formed in 2006, with a museum established two years later.

[14] In July 2007, construction was completed on a new city hall and public works facility on Melaleuca Lane.

[15] According to the United States Census Bureau, the city has a total area of 5.79 square miles (15.0 km2), all land.

[25] As of 2000, Greenacres had the ninety-ninth highest percentage of Cuban residents in the United States, with 2.41% of the populace (tied with Forest, Mississippi).

[26] It also had the ninety-seventh highest percentage of Colombian residents in the United states, at 1.67% of the city's population.
