Summary
Williamson County requires a Building Permit before anyone locates, erects, or begins construction, reconstruction, extension, conversion, or structural alteration of any building or structure in the unincorporated county. Section 8.03(C) of the Zoning Ordinance sets that applicability, and Section 8.03(B) puts approval authority with the Building Codes Director, who reviews each application against the adopted Building Codes.
Building Permits shall be required before a property owner or applicant can locate, erect, or begin construction, reconstruction, extension, conversion, or structural alteration of any building or structure.
Full Breakdown
03(E) routes review through the Common Review Procedures of Article 3, with the Building Codes Director distributing the application to other county departments for comment before deciding whether to issue the permit. 01, which the Ordinance notes 'does not signify building codes review or approval' by itself. Because this Ordinance is the county's zoning instrument rather than its adopted Building Codes, it does not itself list the specific code editions Williamson County has adopted; applicants confirm current code editions and permit fees directly with the Building Codes Department before submitting plans, particularly since this Ordinance took effect January 1, 2013 and adopted code editions are updated on a separate cycle.
Violations & Fines
Starting construction without an approved Building Permit violates Section 22.03(A), which bars any construction 'without all of the required permits, certificates, or other forms of authorization.' Section 22.07(A) classifies the violation as a misdemeanor carrying a fine of ten to fifty dollars per offense under Tennessee Code Annotated Section 13-7-111, with each day of unpermitted construction charged as a separate offense, and the Building Codes Director can pursue civil enforcement in addition to that fine.
