Controlled on a city by city basis. In chicago the land lord must tell you exactly where the money is deposited pay you interest, and provide a precise disclosure from the city (even if there’s no deposit) or the whole lease is invalid. Most land lords therefore charge non-refundable “move in fees”. Other cities are different.
