Print and PDF download versions of the 2018 South Carolina codes are available for pre-order from the ICC website and will be available in early February 2020.
Updating information
The Council has noticed that a few modular manufacturers have changed Third Party Inspection Agencies without notifying Council staff. Please remember that state law requires you to report any and all changes concerning your license to the Council within 10 days. This includes a change in contact information or a change of Manufacturer’s Representative. Please confirm that the Council has the correct information.
All applications and forms were updated in 2019. Please be sure to use the updated applications and forms from the website when submitting anything in paper form to the Council.
If you have any questions or concerns, please contact Maggie Castles at 803-896-4688.
