What you need to know about full home renovation:
- A full home renovation touches every system in the house: structural repairs, new layouts, plumbing, electrical, HVAC, and finishes. It is fundamentally different from a room refresh.
- The national average cost is $52,135 for a 1,250 to 1,600 square foot home, but gut renovations with structural changes run $60 to $150 per square foot and significantly more in coastal luxury markets.
- The sequence of work is non-negotiable: structure and systems before finishes. Reversing that order wastes money.
Read on for a complete phase-by-phase breakdown, realistic cost tables, and what makes a Hilton Head full renovation different from the national average.
What Is a Full Home Renovation?
A full home renovation is a complete overhaul of an existing home’s interior systems and finishes. It covers structural repairs, layout changes, new plumbing, updated electrical, HVAC replacement or redesign, and all cosmetic finishes throughout.
A gut renovation takes the home down to the studs. A full renovation short of a gut still addresses every major system.
The distinction matters for budgeting. Cosmetic renovations paint and replace fixtures. Full renovations open walls and ceilings to reach what is inside them.
Full Renovation vs. Cosmetic Refresh: Key Differences
- Cosmetic refresh: New paint, light fixtures, hardware, flooring over existing subfloor. No wall opening. Costs $15 to $60 per square foot.
- Partial renovation: One or two rooms gutted with new MEP work, rest of home cosmetically updated. Costs $40 to $100 per square foot depending on scope.
- Full home renovation: All rooms touched, systems updated throughout, possibly layout changes. Costs $60 to $150 per square foot for standard work; $150 to $300+ per square foot for luxury coastal properties.
- Gut renovation: Every wall and ceiling opened, down to framing. Complete new systems, new finishes. Costs $100 to $400+ per square foot depending on market and finish level.

What Does a Full Home Renovation Cost?
A full home renovation costs $52,135 on average nationally for a 1,250 to 1,600 square foot home, according to Angi’s 2026 house renovation cost data. Most projects fall between $19,471 and $88,343 for standard scope. Complete gut renovations with structural changes run $100,000 to $650,000 and beyond.
The number that matters for your project is not the national average. It is what drives cost up or down from that baseline.
What Drives Full Renovation Cost
- Labor: The single largest cost category, typically 40 to 60 percent of total budget. Skilled labor in the Hilton Head and Lowcountry market runs higher than national averages.
- Systems age: Homes older than 30 years frequently require full electrical panel replacement, cast iron drain replacement, and HVAC redesign. These are not optional.
- Structural discovery: Opening walls in older coastal homes reveals moisture damage, corroded fasteners, and substandard original framing.
- Layout changes: Moving a load-bearing wall adds $5,000 to $25,000 depending on what it takes to support the structure above. Relocating plumbing adds $3,000 to $15,000 per fixture group moved.
- Finish level: Builder-grade finishes run $25 to $40 per square foot for interior finishing. Luxury finishes run $100 to $200 per square foot.
Full Renovation Cost by Home Size
| Home Size | Standard Renovation | Full Gut Renovation |
|---|---|---|
| Under 1,000 sq ft | $25,000 to $60,000 | $60,000 to $150,000 |
| 1,000 to 1,600 sq ft | $52,000 to $95,000 | $100,000 to $240,000 |
| 1,600 to 2,500 sq ft | $85,000 to $150,000 | $160,000 to $375,000 |
| 2,500 to 4,000 sq ft | $130,000 to $240,000 | $250,000 to $600,000 |
| Luxury coastal, 3,000+ sq ft | $300,000 to $600,000+ | $450,000 to $1.2M+ |
Costs shown are general estimates. Not a quote. Hilton Head Island and Lowcountry market pricing typically runs 15 to 30 percent above inland South Carolina averages due to coastal material requirements, island supply logistics, and elevated labor rates.
What Is the Right Order to Renovate a House?
The right order for a full home renovation is: structure and exterior first, mechanical and electrical systems second, insulation and drywall third, finishes and fixtures last. Doing finish work before systems are complete wastes money on materials that get damaged or removed.
This sequence is not arbitrary. Each phase depends on the one before it.
Phase 1: Planning, Design, and Budget
Before any wall is touched, the design has to be resolved on paper.
What this phase includes:
- Scope definition: what needs to change versus what is acceptable to keep
- Architectural drawings if layout changes are involved
- Structural engineering report if load-bearing walls are being removed
- Permit applications (Beaufort County requires permits for all plumbing, electrical, and structural work)
- ARB submission for applicable gated communities: Sea Pines, Palmetto Dunes, Indigo Run, and others require approval before any exterior change
- Contractor selection and subcontractor roster confirmation
- Long-lead material procurement: custom cabinetry (12 to 18 weeks), specialty tile (6 to 12 weeks), appliances (6 to 12 weeks)
Budget tip: Set aside 15 to 20 percent of the total project cost as a contingency before any work begins. In coastal homes especially, opening walls frequently reveals moisture damage, corroded fasteners, or structural issues that were not visible during the pre-renovation assessment.
Timeline: 8 to 16 weeks for design, permitting, and procurement. Add 3 to 6 weeks for ARB review in gated communities.
Phase 2: Demolition and Structural Work
Demolition comes before anything else. The entire demo scope completes before construction pricing is finalized, because what is behind the walls determines what the project actually costs.
What this phase includes:
- Interior demolition: removal of finishes, drywall, flooring, cabinets, fixtures
- Hazardous material assessment: homes built before 1980 require asbestos and lead paint testing before demo proceeds
- Foundation inspection and repair: address cracks, waterproofing issues, or settlement
- Framing repairs and structural modifications: load-bearing wall removal, new openings for windows or doors
- Exterior work: new roofing, siding, windows, and doors. The home must be weathertight before interior systems are installed.
Key principle: Demolition and structural work must be complete and inspected before MEP rough-in begins.

Phase 3: Mechanical, Electrical, and Plumbing Rough-In (MEP)
MEP rough-in is the most expensive phase per hour of labor. It is also where the most expensive mistakes happen if the design was not fully resolved before demolition.
Electrical
- New wiring throughout: 14-gauge for lighting circuits, 12-gauge for outlets, dedicated 20-amp circuits for kitchen and bathroom appliances
- Panel upgrade if the existing panel is undersized (common in homes over 25 years old)
- Smart home wiring must be roughed in before drywall: low-voltage runs for lighting control, audio, security, and networking
- GFCI protection at all wet locations
Plumbing
- New supply lines: copper or PEX replacing cast iron or galvanized steel in older homes
- Drain, waste, and vent reconfiguration if layout changes are moving fixtures
- In a full gut, all supply and drain runs are replaced regardless of apparent condition
HVAC
- New ductwork design based on the updated floor plan
- Equipment sizing recalculated for the home’s new insulation levels
- Fresh air ventilation: required by building code in tightly sealed renovated homes
Inspection checkpoint: MEP rough-in requires a passed inspection before insulation and drywall can proceed.
Phase 4: Insulation and Drywall
Once MEP rough-in passes inspection, the walls get closed.
What this phase includes:
- Insulation: Spray foam or batt insulation in all exterior walls and ceilings. In coastal homes, vapor barrier placement is specific to the hot-humid climate of the Lowcountry.
- Drywall: Hang, tape, mud, and sand. Moisture-resistant drywall in all wet zones.
- Specialty wall finishes: Venetian plaster or Roman clay are applied before painting; any specialty texture work happens at this stage.
Why this matters for sequencing: Flooring goes in after drywall is complete to avoid dust damage. Cabinets go in after flooring in most cases to avoid height conflicts with floating floors.
Phase 5: Finishes and Fixtures
This phase is where the project comes together visually. It is also where budget overruns happen if material selections were not locked in during Phase 1.
Installation sequence:
- Cabinetry and built-in millwork first (kitchen cabinets, vanities, built-ins)
- Tile (it is the base layer in bathrooms and kitchens)
- Painting: prime after drywall, finish coat after trim
- Trim: baseboards, door and window casings, crown molding
- Hardwood flooring last, after all other finish work is complete
- Plumbing fixtures: faucets, showerheads, toilets, tub fillers
- Electrical: outlet covers, lighting fixtures, under-cabinet lighting
- Appliance hookup and final testing
Coastal-specific note: Acclimate hardwood flooring for 5 to 7 days minimum before installation in Lowcountry humidity. Install flooring at the end of the project, never mid-construction.
Final inspection: All finish work must pass final inspection before the certificate of occupancy is issued.
What Are the Most Common Mistakes in a Full Home Renovation?
Most full renovation problems trace back to decisions made in the first two weeks. By the time they show up in the build, they are expensive.
- Finalizing finishes before demo is complete: The cabinet design gets drawn before the walls are open. Demo reveals a plumbing stack where the island was supposed to go. Plan for a design revision contingency.
- Skipping the pre-construction site review: A contractor who does not assess existing plumbing, structural framing, and electrical capacity before writing a scope is guessing. Guesses become change orders.
- Treating the contingency as upgrade money: Owners spend contingency funds on material upgrades. Then moisture damage in the subfloor becomes a budget crisis. Keep it separate.
- Wrong sequence for finishes: Painting before trim. Tile before plumbing rough-in passes inspection. Flooring before drywall dries. Each costs money to redo.
- Underestimating coastal requirements: Flood zone foundation work, salt-air materials, hurricane-impact windows, and ARB approvals add cost and timeline that national renovation averages do not capture.

How Long Does a Full Home Renovation Take?
A full home renovation on Hilton Head Island takes 6 to 18 months from first design meeting to final punch-list, depending on scope, the age of the home, and whether ARB approval is required. The timeline breaks down as follows:
| Phase | Duration | Key Dependencies |
|---|---|---|
| Design, planning, procurement | 8 to 16 weeks | ARB approval adds 3 to 6 weeks |
| Demo and structural work | 2 to 6 weeks | Inspection required before MEP begins |
| MEP rough-in | 3 to 6 weeks | Structural inspection must pass first |
| Insulation and drywall | 2 to 4 weeks | MEP inspection must pass first |
| Finishes, fixtures, punch-list | 6 to 16 weeks | Custom material lead times drive this range |
| Total | 6 to 18 months | Complex gut renovations or ARB communities at the higher end |
Starting design work in fall (September through November) gives the best subcontractor availability and faster Beaufort County permit processing. Contractors on Hilton Head are busiest March through July.
Why Full Renovations on Hilton Head Island Cost More
Hilton Head Island and Beaufort County add specific cost factors not in national renovation averages.
- Coastal material specifications: Exterior-facing materials require salt-air rated components. Fasteners must be 316 marine-grade stainless. Exterior trim must be fiber cement or solid PVC. Standard materials corrode on the island within 3 to 5 years.
- Flood zone foundations: Most Hilton Head properties sit in FEMA flood zones. Structural work affecting the building’s foundation or first-floor elevation requires compliance with base flood elevation requirements: add $15,000 to $40,000 for pile or elevated foundation work.
- ARB requirements: Sea Pines, Palmetto Dunes, Indigo Run, Colleton River, and Palmetto Bluff all have architectural review boards. Exterior changes require ARB approval before permits are issued. Plan 3 to 6 additional weeks.
- Island logistics: Large material deliveries coordinate around bridge access. This affects scheduling and sometimes adds cost.
In our experience managing full renovations on Hilton Head Island, projects that get into trouble are the ones where the pre-construction phase was rushed. The design, permits, material procurement, and subcontractor scheduling are the real work. Construction follows from that.
Frequently Asked Questions about Full Home Renovation
Can I Finance a Full Home Renovation Without Refinancing My Mortgage?
Yes. The most common options are a home equity line of credit (HELOC), a home equity loan, and a renovation-specific loan such as a Fannie Mae HomeStyle or FHA 203(k). A HELOC gives you a revolving credit line at variable rates. A home equity loan delivers a lump sum at a fixed rate. For Hilton Head homeowners with significant post-pandemic equity gains, a HELOC is often the most flexible tool for a phased renovation. Talk to a lender before assuming a cash-out refinance is the right move. If your existing rate is below current market, refinancing to fund a renovation may cost more in long-term interest than the renovation itself.
How Do I Decide What to Fix First When Everything Needs Attention?
Triage by system before cosmetics. Water intrusion, structural compromise, electrical hazards, and HVAC failure all take priority over kitchens and bathrooms, regardless of how visible or exciting those spaces are. In older coastal homes especially, the real problems are often behind the walls: moisture-damaged framing, corroded plumbing, or an undersized electrical panel. Spending $80,000 on a kitchen before addressing a failing subfloor or a deteriorating roof is the single most common mistake in full home renovation. Get a full home inspection before you scope the project. Let the inspector’s findings set the priority order, not Pinterest.
At What Point Does a Full Renovation Cost More Than Building New?
When the renovation scope approaches $200 to $250 per square foot on a home with significant structural issues, the math starts to favor new construction. On Hilton Head Island, custom new construction starts at $350 to $500+ per square foot. A renovation that reaches $300 per square foot after discovery costs (rotten framing, failed foundation elements, full MEP replacement) is not far off. The tipping point depends on what the lot is worth, whether the existing structure can be saved efficiently, and what the finished product needs to deliver. Ask your contractor to run both scenarios side by side before committing to either path.
How Do I Vet a Renovation Contractor Before Signing a Contract?
Ask for three things: a list of completed full renovation projects in your specific market with client references you can call directly, a named subcontractor roster (not “we use licensed subs”), and a written pre-construction process that shows how they handle permitting, procurement, and ARB submissions. A contractor who cannot give you all three is not ready for a full home renovation at the luxury tier. Also check South Carolina Contractor’s Licensing Board registration and verify their general liability and workers’ compensation certificates are current. On Hilton Head Island specifically, ask how many full renovations they have completed inside gated ARB communities. The answer tells you whether they know the process or are learning it on your project.
Is It Worth Renovating a Vacation Home or Investment Property on Hilton Head?
It depends on the rental income model and the current condition of the property. Hilton Head vacation rentals in renovated homes command meaningfully higher nightly rates than dated interiors in the same community. A full renovation that brings a property to current luxury expectations can increase short-term rental revenue by 30 to 60 percent depending on the platform, the community, and the quality of the finish. The break-even on renovation cost versus increased rental income typically runs 4 to 7 years for a well-executed project. The strongest case for renovating an investment property is when the existing condition is actively depressing occupancy rates or reviews. At that point the renovation pays for itself faster than a sale and repurchase would.
