The phrase was apparently quoted from a famous Shinsengumi TV drama. "This house is under investigation" or We hereby will search this premises", something like that. 御用 as starter of a phrase usually refers to (things done in name of) the government and specifically Bakufu in this context and 改め as a follow-up word means investigation/examining; its modern equivalent would be (coerced) house search.
