Into the early 1900s, Groveton became home to new businesses as pioneer industries dwindled, growing increasingly unnecessary. Many sugar bushes were in operation and blueberries were farmed from the nearby marshes to generate an income. Around the 1920s, a new inn was constructed in the community called Groveton Inn. The inn was a popular spot for local entertainment such as dances. The inn operated until the mid-century when it was converted into a home. In the 1940s, a sawmill was in operation for a few years before ceasing operations. After the 1950s, the community continued to decline with all businesses eventually ceasing operations, including the school and post office.
