/ Hub · IMC 2024 · Daily Code Talk
International Mechanical Code, organized the way a permit set is reviewed.
Teaching edition is 2024 IMC. Live Florida permits follow the adopted FBC Mechanical — see FBC vs IMC.
Daily Code Talk walks the 2024 IMC section by section. This hub is the map: chapter, what plan review actually checks, the free posts, and the working guide when one exists.
