In the Czech Republic, building authorities are increasingly forcing owners to remove caravans from their own plots following neighbor complaints. Under the new building law, a caravan on wheels with a valid technical inspection can be classified as a 'product serving the function of a building' if it remains stationary for several months and is used for living or recreation. Fines for such violations reach 400,000 CZK for individuals, and up to 4 million CZK in protected areas.
