Planning permission or building permit refers to the approval needed for construction or expansion (including significant renovation), and sometimes for demolition, in some jurisdictions.[6][7] Failure to obtain a permit can result in fines, penalties, and demolition of unauthorized construction if it cannot be made to meet code.Since building permits usually precede outlays for construction, employment, financing and furnishings, they are often used as a leading indicator for developments in other areas of the economy.This type of permit is issued by a national broadcasting authority, but does not imply zoning any other permission that must be given by local government.In Canada, the Canadian Radio-television and Telecommunications Commission maintains a comparative process in issuing permits, ensuring that a variety of programming is available in each area, and that as many groups as possible have access to free speech over radio waves.
