The borough owns and operates the water-works and the electric lighting plant. The town site of Warren was laid out by commissioners appointed by Governor Thomas Mifflin in 1795, and Warren was incorporated as a borough in 1832; it was named in honour of Joseph Warren, the American patriot. In 1895 part of Glade township was annexed.
