Stup shares the same last name as current District 3 Del. J. Anita Stup, R-Frederick/Washington. He said he is a distantly related to Anita Stup's husband and considers the delegate "an extremely good friend."
But Stup, who calls himself a conservative Democrat, added he intends to chart his own course in running for office.
"I offer another view that really hasn't been reflected in this district for many years," he said.
He said that view is of someone who has a blue-collar background, having worked his way up the ladder in the surveying business. He is now the director of and project manager of Loiderman Associates Inc.
He also has a variety of experience working on various boards and commissions, and has testified before General Assembly committees on various land-use matters and other issues. That experience would serve him well if he is elected, he said.
District 3 includes all the city of Frederick and much of the western half of Frederick County. It also includes communities in the northeast and northern parts of Washington County, including Smithsburg, Cascade and Maugansville.
Anita Stup already has said she is not seeking re-election to the three-member district this year. Neither of the other two House incumbents, Republican Del. Louise V. Snodgrass and Democratic Del. Sue Hecht, have formally announced their plans.
Joseph R. Bartlett, the son of U.S. Rep. Roscoe G. Bartlett, R-Md., is the only candidate other than Rick Stup to formally file for election in the district.
Members of the House of Delegates make $29,700 a year. The primary election this year is Sept. 15. The general election is Nov. 3.
