Important Message

Hananan City offices are open to the public. Permit applications may still submitted online and citizens are encouraged to continue to do so when applicable.


No building construction, reconstruction, alteration or repairs; no swimming pool construction, reconstruction, alteration or repairs; no electrical construction, reconstruction, alteration or repairs; no mechanical construction, reconstruction, alteration or repairs; and no gas construction, reconstruction, alteration or repairs, unless it is metered gas, shall be installed within or on any building, structure or premises without first securing a permit therefor from the building official or his assistants authorized to issue such permits. Applications for permits shall be made on forms provided for this purpose by the building official.

New construction plans are reviewed for conformance with the International Building, Plumbing, Mechanical, Fuel, Gas, and Fire Prevention Codes; the International Residential Code; the National Electrical Codes; and the State handicapped accessibility requirements. Conformance with Federal Floodplain Management requirements is also verified through the Plan Review process. The City is now a MS4 for Stormwater Management, so on commercial projects you will have to submit plans for retention of your stormwater runoff; once Berkeley County approves your water management plans they are submitted to OCRM at DHEC. Once we have approval from OCRM then you can receive your building permits. Prior to the plans being released for construction, approvals are also received from the Zoning Administrator.

Once all of the approvals are obtained for a project, a building permit is issued for construction. Contractors obtaining permits are required to have a State of South Carolina contractor’s license, and a City of Hanahan business license for any type of construction. All licenses are verified prior to a building permit being issued.

Separate permits are required for electrical, plumbing, mechanical, gas, fire suppression, and alarm systems. Contractor licenses are also verified prior to the permits being issued. As construction proceeds, inspectors verify conformance to the adopted codes of the work in progress. Commercial projects require numerous inspections depending on the magnitude of the project.
