Beaufort County splits this work across three departments: Building Inspections permits construction, Planning and Zoning issues zoning and development permits, and Code Enforcement issues no permits and collects no fees at all.
This Beaufort County building permit guide covers which department to approach, the vegetated river buffer measured landward of the OCRM critical line, the county business licence required from every subcontractor, the full calculation set plans must carry, and the state Special Inspection Manual.
Scope: unincorporated Beaufort County. Beaufort, Bluffton, Hilton Head Island, Port Royal and Yemassee permit their own work.
Three departments, and only one of them issues building permits. Building Inspections handles construction and permitting. Planning and Zoning issues zoning and development permits. Code Enforcement issues no permits and collects no fees. Most wasted calls in Beaufort County start with the wrong one.
What requires a permit in Beaufort County?
Beaufort County splits this work across three departments, and getting the wrong one costs days. The Building Inspections Department handles all issues relating to building construction and building permitting. Planning and Zoning issues zoning and development permits. Code Enforcement issues no permits and collects no fees at all — it handles complaints under the Community Development Code.
Building Inspections enforces the building codes, fire code, National Electrical Code, floodplain regulations and dilapidated abandoned structures; issues permits for new construction, substantial improvements and additions; registers all manufactured homes placed in the county including in the municipalities; and staffs the Construction Board of Adjustments and Appeals. That manufactured-home function reaches into the towns, which is unusual.
Beaufort is one of the eight coastal counties, and unlike Berkeley or Dorchester it has genuine oceanfront — Hilton Head Island, Daufuskie, Bay Point, St. Phillips and Little Capers among the shorelines carried through the state's current jurisdictional line review. Beaufort, Bluffton, Hilton Head Island, Port Royal and Yemassee permit their own work.
The enforced code is the South Carolina Building Codes — the International Codes as adopted with South Carolina modifications by the South Carolina Building Codes Council under S.C. Code Ann. § 6-9-50, then administered and enforced locally. South Carolina is mid-changeover. The codes in force today are the 2021 South Carolina Building Codes, effective 1 January 2023. On 26 August 2025 the Building Codes Council adopted the next cycle — the 2024 editions of the International Building, Residential, Fire, Plumbing, Mechanical and Fuel Gas Codes, together with the 2023 National Electrical Code — and set the implementation date for every municipality and county as 1 January 2027. Design to the 2021 codes for a permit pulled now; design to the 2024 codes for anything that will be applied for after the turn.

Beaufort County building department: who handles permitting
The residential plan requirements are more prescriptive than most. Plans must include an HVAC plan with Manual J, load calculations, duct size and layout; a plumbing plan with riser diagram and water supply for fixture units; an electrical plan with panel location and load calculations; and a RES Check document. A package missing the RES Check or the Manual J is not a complete package.
Beaufort County requires its own business licence. The submission includes a list of subcontractors with their state and Beaufort County business licence number. That is the opposite of York County, which requires no business licence at all to contract in its unincorporated areas — a reminder that the local licence question has to be asked county by county.
You pay the building permit fee, and impact fees where applicable, upon submittal rather than at issuance. Once the permit is reviewed and entered into the system you are notified to come and collect it. Inspections are requested by email to the department or by phone on 843-255-2078.

🌊|The OCRM critical line is written into the county's own code. Beaufort County's vegetated river buffer, at Table 5.11.60(A) of the Community Development Code, is measured landward of the OCRM critical line — so the state's coastal boundary directly sets a local development standard. A building permit is not a coastal permit. SCDES authorisation is required for all proposed activities located wholly or partially within the state's critical areas, and that authorisation is separate from — and additional to — the county or municipal building permit. Neither one substitutes for the other, and a local permit issued in ignorance of a critical area does not cure the omission.
Beaufort County permits: record types and what each covers
Beaufort County's records are split across Building Inspections and Planning and Zoning, so most projects open more than one:
Residential permit types
| Permit type | What triggers it | Review path | Fee basis |
|---|---|---|---|
| New construction | New dwellings, additions, and accessory structures above the local size threshold | Full plan review against the adopted South Carolina Residential Code, plus zoning | Valuation-based |
| Renovation / alteration | Structural changes, layout changes, or added plumbing, mechanical, or electrical | Plan review scaled to scope; the property maintenance and existing-building provisions apply only where locally adopted by ordinance | Valuation-based |
| Reroof | Roof covering replacement, recover, and structural deck repair | Dry-in and deck inspection; plan review rarely required | Valuation or squares |
| Solar photovoltaic | Rooftop or ground-mount arrays, with or without battery storage | Electrical review led, with structural review of the attachment | Flat or system-size based |
| Battery energy storage | Wall or floor-mounted storage added to a dwelling | Electrical review plus fire separation and location check | Flat or per-permit minimum |
| Electrical | Service changes, panel upgrades, new circuits, EV chargers, and rewiring | Trade review; filed under a mechanical contractor holding the Electrical subclassification | Per-permit minimum or per-device |
| Plumbing | New piping, repipes, fixtures, gas piping, and water heater replacement | Trade review under a mechanical contractor holding Plumbing | Per-permit minimum or per-fixture |

Commercial permit types
| Permit type | What triggers it | Review path | Fee basis |
|---|---|---|---|
| New commercial construction | Ground-up commercial, industrial, and institutional buildings | Concurrent review against the adopted South Carolina Building Code, fire, and zoning | Valuation-based |
| Tenant improvement / upfit | Interior fit-out of an existing tenant space | Building, trade, and life-safety review; accessibility attaches on change of use | Valuation-based |
| Change of occupancy | Converting a building or space to a different use group | Occupancy classification, egress, and accessibility review | Valuation or flat |
| Commercial electrical | Service, distribution, and branch circuit work | Trade review under a mechanical contractor holding Electrical | Per-permit or valuation |

| Land disturbance | Clearing, grading, and stormwater-triggering site work | Erosion and sediment control review, separate from the building permit | Acreage-based |
| Commercial demolition | Full or partial demolition of a commercial structure | Utility disconnect, asbestos notification, and site restoration | Flat or valuation |
Residential
- Single-discipline review in most cases
- Trade records filed separately under Title 40 Chapter 11 licences regardless of job value
- Residential builder licence required above the statutory threshold; residential specialty above a much lower one
- Septic properties need SCDES approval before the county can issue
Commercial — multi-discipline
- Concurrent review across building, trades, fire, and zoning
- Signed and sealed plans across every affected discipline
- Licence group caps the value of a single bid or job, separately from the permit
- Accessibility and life-safety review attach to any change of occupancy

Solar permits in Beaufort County
Solar is reviewed on two tracks at once across South Carolina: the electrical side (conductors, overcurrent protection, rapid shutdown, labelling, and the service or supply-side connection, against the adopted National Electrical Code) and the structural side (attachment detail, rail spacing, and whether the existing framing carries the added dead load).
Solar in unincorporated Beaufort County needs the electrical plan with panel location and load calculations that the county requires of every submission, and the installer's subcontractor entry must carry both a state and a Beaufort County business licence number. Confirm which classifications your installer actually holds before the application is filed, because a single rooftop array can cross the general contractor Miscellaneous Metals subclassification for the panels, Roofing or Building for the mounting, and a mechanical contractor holding Electrical for the wiring and connections.
The licensing split is the part that catches installers. South Carolina puts solar panel installation under the general contractor Miscellaneous Metals subclassification, but roof mounting may only be performed by a general contractor holding Roofing or Building, and wiring and connections may only be performed by a mechanical contractor holding Electrical. Structural upgrading of the roof to carry the array goes to a general contractor with Building or Structural Framing. One array, potentially three licences.
Utility interconnection runs on its own clock alongside the permit. Dominion Energy South Carolina, Duke Energy Carolinas and Duke Energy Progress, Santee Cooper and the state's electric cooperatives each set their own application, meter, and witness-test sequence. Permission to operate is not something the building department controls, so plan for the two tracks to finish at different times.
Roofing permits in Beaufort County
A roof covering replacement needs a permit across most of South Carolina. The permit is usually quick, but it is not optional, and the inspection that matters happens before the covering goes on rather than after.
Because South Carolina enforces a statewide adopted code, there is no state product-approval database to search and no approval number to cite on the application. The assembly has to comply with the adopted code and the manufacturer's listed installation instructions, and that pairing is what the inspector checks — which makes the manufacturer's instructions a document worth having on site.
A reroof in unincorporated Beaufort County cannot begin until the permit card is placed in a conspicuous location on the premises, and the card must be maintained until the Certificate of Occupancy. Roofing is its own general contractor subclassification in South Carolina, and it absorbed the former General Roofing and Specialty Roofing classifications, so an older pocket card can read differently from the current licence record — check the LLR verification lookup rather than the card alone.
Sequencing is where reroofs go wrong. The deck and dry-in condition has to be visible when the inspector arrives, so covering it first means opening it back up. Where a previous layer has been torn off, expect attention to deck fastening and to any sheathing replaced along the eaves.
Beaufort County permit cost
Beaufort County permit fees scale with the type and valuation of the work, and are payable on submittal along with any applicable impact fees rather than at collection. Budget the outlay earlier in the programme than you would in most South Carolina counties.
The local business licence is a real cost line here. Every subcontractor needs a Beaufort County business licence number as well as a state licence number, and the list goes in with the submission. Confirm current fee amounts against the county before budgeting.
| Fee component | How it works |
|---|---|
| Building permit | By type and valuation, payable on submittal |
| Impact fees | Where applicable, also payable on submittal |
| Business licence | Beaufort County licence needed by every subcontractor |
| Special inspections | Arranged by the applicant under the state manual |
| Coastal critical area | SCDES authorisation is separate and additional |
| Trade permits | Electrical, mechanical, plumbing charged separately |

Beaufort County trade permits
Electrical, mechanical and plumbing work each need their own permit and a South Carolina licensed contractor. Four Beaufort County specifics:
Two licence numbers per subcontractor
The submission includes a list of subcontractors with their state and Beaufort County business licence numbers. A state licence alone is not sufficient here.
Bring the calculations, not just the drawings
Plans must include Manual J and duct layout for HVAC, a riser diagram and fixture-unit water supply for plumbing, panel location and load calculations for electrical, and a RES Check document.
Special inspections follow the state manual
Where IBC Chapter 17 applies, the county follows the state-mandated Special Inspection Manual published by SC LLR, and the Deputy Building Code Director requires contact information for the selected special inspectors.
Post the card before you start
Work requiring a permit shall not commence until the permit card is placed in a conspicuous location on the premises, and the card must be protected and maintained in place until the Certificate of Occupancy.
Beaufort County permit application: how to apply step by step
Here is how to get a building permit in Beaufort County, from confirming the requirement through to close-out. Each step below corresponds to a real decision point where projects commonly stall.
Building Inspections for construction and permitting; Planning and Zoning for zoning and development permits; Code Enforcement for complaints, which issues no permits and collects no fees.
Beaufort is a coastal county with real oceanfront. Check the SCDES beachfront lines and the county's vegetated river buffer landward of the OCRM critical line, plus the FEMA digital flood maps released for coastal Beaufort County.
HVAC with Manual J, load calcs and duct layout; plumbing with riser diagram and fixture-unit supply; electrical with panel location and load calcs; and the RES Check document.
Compile the list of subcontractors with both their state licence numbers and their Beaufort County business licence numbers before submitting.
The building permit fee and any applicable impact fees are payable on submittal. You will be notified to collect the permit once it has been reviewed and entered.
Place the permit card conspicuously before work begins and maintain it to Certificate of Occupancy. Request inspections by email or on 843-255-2078.
Inspections in Beaufort County
Inspections are requested by email to the department or by telephone on 843-255-2078, giving the details the department asks for with the request. The county publishes a general list of required inspections, and notes that based on the scope of work the Building Official, Plans Examiner or Field Inspector may require additional inspections beyond that list.
Posting the permit is a precondition of starting. Work requiring a permit shall not commence until the permit card is placed in a conspicuous location on the premises, and the card must be protected and maintained in place until the Certificate of Occupancy is issued.
On the oceanfront, S.C. Code Ann. § 48-39-280 requires SCDES to establish and periodically review two beachfront jurisdictional lines. The baseline is the more seaward of the two; the setback line is the more landward, and it marks the landward extent of the state's direct permitting authority within the Beach/Dune System Critical Area. The beach/dune system itself runs from the mean high-water mark of the Atlantic landward to the forty-year setback line — the figure comes from the state's forty-year retreat policy. Being landward of the setback line does not automatically put you outside SCDES jurisdiction. Two other beachfront critical areas — the Beaches Critical Area and the Coastal Waters Critical Area — can extend landward of the setback line, and where they do, activities there still require coordination and authorisation from SCDES. Critical areas are dynamic. The Department asks to be contacted to determine whether critical areas extend landward on a specific parcel rather than having applicants infer it from the line viewer.
The lines move. South Carolina law requires SCDES to establish and review their position every seven to ten years, and a review cycle is running now: SCDES released a tentative schedule on 30 January 2024 for a phased establishment of new beachfront jurisdictional lines between 2024 and 2028. The previous positions were fixed by Act 173, the Beachfront Management Reform Act, signed 3 May 2018. If you are planning oceanfront work across the next two years, check whether your stretch has been through the current cycle before relying on a line position. SCDES publishes a South Carolina Beachfront Jurisdictional Lines Viewer showing the approximate position of the baseline and setback line together with adopted long-term erosion rates. Treat it as approximate: it is a screening tool, not a survey, and the Department's own guidance is to speak to Beachfront Management on 843-953-0200 or find the project manager for your area through its Project Manager Finder before committing a design.
For commercial work within IBC Chapter 17 scope, special inspections are required and Beaufort County follows the state-mandated Special Inspection Manual published by the South Carolina Department of Labor, Licensing and Regulation. The Deputy Building Code Director requires contact information for the selected special inspectors on the project, so appoint them early.
Permits expire and renew in accordance with the administrative chapters of the adopted codes. Expired permit files are pulled, marked and stored, and projects left unattended after expiration are monitored.

Frequently asked questions
Who issues building permits in Beaufort County, SC?
The Beaufort County Building Inspections Department handles all issues relating to building construction and building permitting. Zoning and development permits come from Planning and Zoning, and Code Enforcement issues no permits and collects no fees.
Do I need a permit for a shed in Beaufort County?
A zoning permit is required before placing any accessory structure. Accessory structures of 200 square feet and larger also require a building permit, and that includes pre-built structures, not just those built on site.
Can I put up a shed on a vacant lot?
No. You cannot place an accessory structure on your property if there is no principal structure.
What plans does Beaufort County require?
An HVAC plan with Manual J, load calculations and duct size and layout; a plumbing plan with riser diagram and water supply for fixture units; an electrical plan with panel location and load calculations; and a RES Check document.
Do my subcontractors need a Beaufort County licence?
Yes. The submission includes a list of subcontractors with their state and Beaufort County business licence numbers. That is different from York County, which requires no business licence in its unincorporated areas.
When do I pay?
The building permit fee and any applicable impact fees are payable upon submittal of the permit, not at collection. You are notified to come and pick up the permit once it has been reviewed and entered.
When can I start work?
Not until the permit card is placed in a conspicuous location on the premises. The card must be protected and maintained in place until the Certificate of Occupancy is issued.
What is the OCRM critical line and why does it matter locally?
It is the state coastal boundary, and Beaufort County writes its own standard from it — the vegetated river buffer at Table 5.11.60(A) of the Community Development Code is established landward of the OCRM critical line.
Does Beaufort County handle special inspections?
Where the IBC requires special inspections for buildings within Chapter 17 scope, Beaufort County follows the state-mandated Special Inspection Manual published by SC LLR. The Deputy Building Code Director requires contact information for the selected special inspectors.
Who registers manufactured homes?
Beaufort County Building Inspections registers all manufactured homes placed in the county, including those placed within the municipalities. Moving a mobile home out of Beaufort County requires a paid tax receipt for the current year.
Is a building permit enough for waterfront work?
No. Beaufort is one of the eight coastal counties, and activities wholly or partially within the state's critical areas need SCDES authorisation separately from and additionally to the county building permit.
Which building code does Beaufort County enforce?
The South Carolina Building Codes as adopted with state modifications, along with the fire code, National Electrical Code and floodplain regulations. The latest edition of ICC/ANSI A117.1 is mandatory statewide under the Accessibility Act.
