What is the penalty for failing to obtain the proper permit?

2024 International Residential Code, R108.6 - Work commencing before permit issuance, states: Any person who commences work requiring a permit on a building, structure, electrical, gas, mechanical or plumbing system before obtaining the necessary permits shall be required to pay two times the established fee for the required permit. The Building Official may waive the doubling of the established fee where the contractor, or other person applying for permit, demonstrates good cause for the failure to obtain the required permit before commencing work. 

Rutherford County Zoning Ordinance, Chapter 14, 1404B. Building Permits Required, No building or other structure shall be erected, moved, added to or structurally altered without a building permit issued by the Director of Building Codes.
