Summary
Kansas City requires a permit before construction, alteration, demolition, or grading work begins, backs it with mandatory inspections at each construction stage, and bars occupancy until the building official issues a certificate of occupancy under Chapter 18.
It shall be unlawful to construct, enlarge, alter, move, raise, shore, demolish, wreck or raze a structure or parking station; or change the occupancy of a building or structure requiring additional strength, exit or sanitary provisions; or to change to another use; or to grade or excavate any land or real estate; or to install or alter any equipment or sign for which provision is made or the installation of which is regulated by this Code; unless a separate permit for each building, premise or structure has first been obtained; provided, however, that repairs, as defined in section 18-4(b), which do not involve any violation of this Code, and work as specified in subsection (b) of this section, shall be exempted from this provision.

Full Breakdown
The Kansas City building official won't issue a permit for construction, alteration, demolition, moving, raising, or grading work until construction documents are filed and reviewed for code compliance under Sec. 18-17 and 18-18, and the Sec. 18-20 fee schedule is paid. Sec. 18-21 requires the permit holder to request inspections at each stage of the job -- footing/foundation, slab or under-floor, rough-in, and final -- and work cannot be covered or concealed until the building official signs off. Sec. 18-23 then bars anyone from using or occupying a building until the building official inspects it and issues a certificate of occupancy, with a temporary certificate available for partial occupancy before the whole project is done.
Violations & Fines
Occupying a structure without a certificate of occupancy, or after a temporary certificate has expired, is unlawful under Sec. 18-23(e). The building official can also suspend or revoke a permit issued in error, based on bad information, or in violation of the chapter under Sec. 18-19(d).
