Residential Building Permits

English | Español

When is a residential building permit required?

A building permit is required whenever you construct, enlarge, alter, repair, move or demolish a building or structure, or if you install or alter electrical, heating, air conditioning or plumbing equipment.

All projects, whether they need a permit or not, must comply with the adopted building codes and regulations and the Hilton Head Island Municipal Code.

Residential Building Permit Process

Step 1. Submit Application for Permit

Single Family Building Permit Application

Step 2. Plan Review

  1. Depending on your proposed project, plans will be reviewed by various divisions.
    • Types of reviews include planning and zoning, structural and fire.
    • The assigned reviewers check to see that your application is in compliance with the specific code or regulations. If the reviewer needs additional information you will be contacted with identified items required.
  2. Revise Plans for Corrections Needed
    • Complete and timely responses will speed up the re-review of the project.
    • If the revisions are complete, the reviewer will sign off and the project will move on in the process (see step 3).
    • If the reviewer needs additional information or has identified additional corrections they will request this information from you (return to steps 2 and 2a).

Step 3. Plans Approved, Permit Issued

  1. When all required reviews are approved, your permit will be in pre-issue status and you will be notified of your final fee total.
  2. After the balance is paid the plans submitter will be notified that the approved plans and permit are available for pick up.

Step 4. Inspections

  1. When you pick up your permit, you will receive an inspection card listing all of the inspections you will need during construction.
  2. Inspections can be scheduled online or by calling 843-341-4757.

Step 5. Certificate of Occupancy

After passing all inspections and submitting any requested final paperwork, you will receive a Certificate of Occupancy for new construction or a "Final" for other construction.
