Dacula is primarily a residential community, and many subdivisions have been built within the city limits in recent years. In earlier times, the Georgia, Carolina and Northern Railway laid tracks through the area that was to become Dacula. In 1905, the city was incorporated. John W. Freeman, who was the first postmaster, was asked to submit six names for the town. To get an original name, he used letters from Atlanta and Decatur, forming the word Dacula.

The name “Dacula” is properly pronounced da-CUE-la (duh-Q-la).
