Planning permission or other building permits are generally not required to build a JC dome. JC dome’s limited footprint, lack of permanent foundation, and the overall design that blends with the surroundings, usually qualify it as a temporary structure, not requiring planning permission.
Different rules may apply in different countries and regions. For example, in the UK JC domes may be considered as outbuildings, same as other small structures such as greenhouses or garden sheds. Outbuildings are permitted development which means they, in general, do not require an application for planning permission.
