There's no such thing in Germany apart from eg leasehold of holiday homes, rented garden houses (Kleingartenvereine) etc. but there are municipal usage restrictions according to Baunutzungverordnung to the effect you can't repurpose residential areas as a commercial space, and local zoning rules according to a Bebauungplan or equivalent for eg how many storeys are allowed, building lines, distances, materials to choose, a duty for at least an effort to gardening, etc., but it depends greatly where you live, ranging from very strict to everything goes.
