Do you need a building permit in Town of Hilton Head Island, SC?

Hilton Head Island requires a building permit for a new home, changes to an existing building, and electrical, plumbing or heating and cooling work.1 Cosmetic work such as painting, new carpet or wallpaper generally does not need a building permit unless part of a larger renovation.1 A permit exemption does not waive the Town’s adopted building codes or municipal regulations.9 For an uncertain project, ask the Town Community Development Information Center before starting work.10

Who issues building permits in Town of Hilton Head Island?

Start a Hilton Head Island building-permit application with the Town’s Community Development Information Center, reachable at 843-341-4757 or [email protected].10 The Town accepts applications through its Citizen Self Service portal, by email or in person at Town Hall.11 The online portal also supports project management and inspection requests.10 Complete applications are reviewed within 20 business days; incomplete applications are returned.11 Approval requires completion of the necessary reviews, payment of fees and resolution of outstanding items.11

Does Town of Hilton Head Island have zoning and lot standards?

Hilton Head Island has its own zoning under the Town’s Land Management Ordinance.2 Town zoning districts set permitted uses, lot sizes, density, setbacks, buffers, landscaping and parking standards, so ask the Development Service Center to identify the district and standards for the parcel before choosing a house plan.5 In RSF-3 and RSF-5, the maximum building height is 35 feet.1213 The RSF-3 maximum impervious cover of 35% applies to development other than single-family development; it is not a single-family lot-coverage limit.14

How do septic permits work inside Town of Hilton Head Island?

A Hilton Head Island home or manufactured home on land not served by public or community sewer needs SCDES approval and a septic installation permit before construction.6 State rules prevent issuance of an onsite wastewater permit where public sewer is accessible, so resolve sewer availability before pursuing septic.15 SCDES evaluates the site’s suitability for a septic system and discusses alternatives if a traditional system is not approved.16 Septic installation also needs an inspection arranged before the system is covered.16 Town building approval and state septic approval are separate responsibilities.13

Can you live in an RV or tiny home in Town of Hilton Head Island?

We could not confirm a complete Hilton Head Island rule allowing residential RV occupancy, temporary camping or tiny-home occupancy on a private parcel; ask the Town Development Service Center about the proposed use and parcel district before buying.5 Ask the same office to confirm accessory-dwelling permission, manufactured-home placement, minimum dwelling size and parcel setbacks.5 A new structure in Hilton Head Island cannot be occupied before the Town issues a Certificate of Occupancy.7 A septic permit addresses wastewater approval, while Town zoning separately governs how land may be used.35

Building a home in Town of Hilton Head Island: what comes first?

  1. Ask the Town Development Service Center for the parcel’s zoning district, permitted use and site standards.5
  2. Resolve public sewer accessibility; if the parcel qualifies for septic, obtain SCDES approval before construction.156
  3. Submit a complete Town building-permit application; plans may need building, fire, floodplain, natural-resource, stormwater and zoning review.11
  4. Resolve corrections and fees, receive the building permit, post the permit and keep approved plans on site.1110
  5. Complete the required inspections and final paperwork, then obtain the Certificate of Occupancy before moving into a new structure.177

What should you check before buying in Town of Hilton Head Island?

Ask the Town Floodplain Administrator for a flood-map determination, elevation-certificate information and the construction requirements for the property.18 For a proposed private residential well, South Carolina requires a Notice of Intent for General Permit coverage before construction; the state permit does not override local restrictions.8 We could not confirm a Town-wide public-water connection rule; ask the Development Service Center about the parcel’s water service and local requirements.5 Owner-builders must submit the Beaufort County disclosure and meet the Town’s own-use and 2-year no-sale-or-rental conditions.4 For land outside Town limits, use the Beaufort County guide for the county building-permit and zoning requirements.1920

Watch-outs

  • Do not move into a new Hilton Head Island structure before receiving its Certificate of Occupancy.7
  • Accessible public sewer can prevent SCDES from issuing a septic permit.15
  • South Carolina’s adopted 2024 building codes are scheduled for local implementation on January 1, 2027; ask the Town building office which edition applies to your application.2110
