Immigration doesn't cause expensive housing. Making it hard and/or expensive to build more causes expensive housing.

Immigration clearly does too. Land in desirable areas is limited, especially for single family homes, which is the kind of housing people usually want and aspire to. Building more is an option sometimes, but it takes time and does not address the root issue of available land, saturation of roads and public transit, etc.
