Rainier became incorporated on November 25, 1885 and the newly elected Board of Trustees met at either the Blanchard & Muckle Store, the home of Dean Blanchard or wherever it was convenient to meet. By June 1891 they decided that they needed a new Town Hall. They purchased a lot for $100 in the Moeck addition located on the south side of West C St. and west of West 3rd St. Four general contractors summitted their bids but the Trustees discarded them, deciding to manage the construction themselves. By the end of 1891 the building had been completed and two years later a jail had been added.

The Town Hall, on more than one occasion, had been used to teach students. The small school on the hill had become overcrowded and in September 1894 W. M. Perry asked the Trustees if students could be taught there while they waited for a new school house to be built across the street, to the east, on land that had been donated to the school district by George Moeck. The new school was completed in 1895 in time for fall classes. Ten years later students were taught there again while four more rooms were added to the original school doubling its size. Students at the town hall remembered hearing grunts and the calls from inmates jailed there over the weekend, wanting to get out as school convened on Monday mornings.

The building was also used for other activities. From 1902 to 1908 the Church of God met there and the town hall was rented to Mr. Day for a dancing school. Rented only at times that did not interfere with town business.

By April 1907, the Trustees decided to sell the town hall. They had out grown the space and it was too far from the center of the business district. In a special election in August 1908, the town's charter was changed and Rainier became a city with an elected mayor and six councilmen with varied appointed committees. On April 3, 1909 the city council met to discuss the selling of the town hall and to locate a site for a new city hall. On April 14 a lot had been suggested for the new city hall and on April 28th the old town hall was sold at public auction to M. Ellis for $925.00.

Though the city had moved out the jail was still used until 1912 when the city purchased a jail tank from the city of St. Helens and had it installed in a rented space in the Lee building. Also, in 1912 the building was again used as a classroom when the school became overcrowded. The Christian Science Society purchased the building in 1920 and held services there until 1923. In the 1930s the Rainier Assembly of God Church began holding services there. Following the April 13, 1949 earthquake that severally damaged the grade school, the building was once again served as a school for two years using their Sunday school classrooms.

In 1987, the 96-year-old structure was torn down. The Rainier Assembly of God Church started construction on a new church in 1980 next door after deciding that it wasn't worth the cost to fix the old building. Also the community lacked any interest in organizing an effort to save the old landmark.
