If the police ask to search your property, you do not have to give them permission to do so.
They cannot just go ahead and search your property unless they have “probable cause” or a search warrant signed by a judge with jurisdiction over the physical location the target property is in.
For example, if police spot something out in the open and determine there was “no reasonable expectation of privacy,” the police can go ahead with a search of your property immediately without a search warrant.
