San Juan Guarita is one of the smallest municipalities of the Honduran Lempira department.

In the administration of Rafael Lopez Gutierrez, a decree was emitted to create the municipality on February 21, 1921.

This caused problems to acquire the official land titles, and they decided to separate from Guarita.

On July 4, 1929, the governor of Lempira department and the military chief laid out the boundaries of the municipality, including its villages.

It had to be respected by both municipalities and its adjudged rights forcing them to take the correcting measures by the Legislative Power.

In 1935, the people were able to get a legitimate copy of the land titles and therefore the relationships among the inhabitants of both municipalities were improved.

As the rest of the department, San Juan Guarita has electricity and mobile communications services.
