Permitting timelines in South Carolina commercial construction vary significantly by jurisdiction, project type, and the completeness of the submission package. A commercial project in Florence County that submits complete, code-compliant drawings can expect a different timeline than a project in a municipality with a backlogged review office. Delta Building Systems has navigated permitting across the region and knows which submissions need extra documentation, which agencies run in parallel, and where pre-submission conversations with reviewers save weeks of back-and-forth.
