The short answer
A gut renovation of a 1,800–2,500 sq ft home runs $100–$250 per square foot in 2026, depending on where you live and what you’re rebuilding. Mid-range work (new systems, mid-grade finishes, no structural changes) lands at $100–$150/sq ft. Projects with layout changes, structural modifications, or high-end finishes reach $200–$350/sq ft.
That puts a typical full home renovation at $180,000 to $625,000. The range is wide because the scope variable is enormous. A full renovation can mean “refresh everything cosmetically” or it can mean “take it to the studs, reconfigure the floor plan, upgrade the panel, replace the plumbing stack, and install a new HVAC system.”
What “gut renovation” actually means
A gut renovation typically means stripping the interior to the framing and rebuilding from there. That includes:
- Structural inspection and repair, the work that becomes visible only after the walls come down
- Electrical replacement, from the panel out, new circuits, new wire gauges, updated AFCI/GFCI protection
- Plumbing replacement, galvanized or cast iron to copper or PEX, new drain lines, new venting
- HVAC replacement, new equipment, new ductwork, or new distribution system
- Insulation upgrade, often the first opportunity to meet modern energy code
- Drywall, ceilings, and trim, the visible layer that most people think of as the renovation
- Flooring, tile, and finishes, where personal preference and budget diverge most
Where the money goes in a full renovation
In a typical 2,000 sq ft gut renovation:
| Category | Share of budget |
|---|---|
| Mechanical systems (HVAC, plumbing, electrical) | 25–35% |
| Framing, structural, insulation | 10–18% |
| Kitchen (cabinets, counters, appliances, fixtures) | 15–25% |
| Bathrooms (fixtures, tile, waterproofing) | 10–18% |
| Flooring (all rooms) | 6–10% |
| Drywall, paint, trim, doors | 8–12% |
| Windows and exterior (if included) | 5–15% |
| General conditions, profit, contingency | 15–20% |
The systems work, electrical, plumbing, HVAC, is where budgets slip most often. It happens behind the walls and can’t be seen until demo. A pre-demo assessment by a licensed electrician, plumber, and HVAC technician before the bid is finalized adds $1,500–$3,000 in professional fees and typically saves $10,000–$30,000 in change orders.
The sequencing problem
A full renovation lives or dies on sequencing. The correct order:
- Demo and structural inspection, discover what’s actually there
- Structural rough work, headers, beams, load adjustments if layout changes
- Rough plumbing, drain, waste, vent lines run before concrete or subfloor goes back
- Rough electrical, wire runs, panel work, boxes set
- HVAC rough, duct runs, equipment placement, air handler location
- Inspections, rough-in inspection before anything is covered
- Insulation, after inspections pass
- Drywall, hung, taped, finished
- Trim, doors, paint, after drywall dries fully
- Flooring, after paint and before cabinets set, usually
- Kitchen and bath finishes, tile, cabinets, fixtures
- Finish electrical and plumbing, trim-out after finishes
- Final inspection, punch list
When a general contractor loses control of this sequence, things go wrong in compounding ways. The most expensive sequence failure: drywall goes up before rough inspections, fails inspection, and has to come down. The firms we match build the inspection calendar into the schedule before demo begins.
What a low bid is usually missing
A full renovation bid at 30% below the other two bids is almost always missing one or more of:
- Permit fees, which can run $3,000–$15,000 on a full gut renovation
- Structural engineering, required for any load change, typically $2,500–$8,000
- Asbestos or lead assessment, required in most states on pre-1980 homes before demo, $500–$2,000
- Contingency, a legitimate scope will carry 10–15% contingency on an existing-conditions project; a bid without it is a bid that will change-order
- Proper systems replacement, a bid that keeps existing electrical or plumbing when replacement is warranted is a bid that will cause problems later
The firms we match specify what is included, what is excluded, and why. A full renovation is not the job for ambiguous scopes.
