The issuance of a building permit is the legal process citizens use in order to carry out construction works.
The issuance of a building permit does not only refer to the unambiguous role of the “issuance”, it also encompasses the entire procedure, beginning with the preliminary project plan (drafts), continuing with the definite project plan (usually synonymous with the issuance of the building permit) and ends with the detailed project plan (i.e. the construction of the project).
Issuing a building permit is not something that need concern you.
Of greater concern should be if what you are getting the building permit for, is what you really want and fits you!
