What a gut renovation includes (and what it does not)
Homeowners and contractors do not always mean the same thing by “gut.” Spell it out in writing. A “gut” that only strips finishes but leaves old wiring and plumbing is not a full gut — call that a deep remodel so bids stay comparable.
- Usually included: demo to studs in scope rooms; new or reworked electrical, plumbing, HVAC paths; insulation, drywall, paint, flooring; kitchen and baths rebuilt; permits for the described work
- Often excluded unless added: structural changes, foundation/framing/roof structure, exterior envelope if separate line items, soft costs, landscape and detached buildings
- Windows, doors, and trim only as specified in the scope
Gut vs cosmetic vs moderate: pick the right band
If your search was “how much to gut renovate a house,” price against the gut band, not the cosmetic one. Mixing those labels is how budgets blow up mid-project.
- Cosmetic refresh: paint, flooring, fixtures, hardware — leave behind-wall systems alone (~$50–$100/sq ft)
- Moderate renovation: new finishes plus selective systems work; layout mostly stays (~$100–$200/sq ft)
- Gut renovation: rooms opened to structure; new electrical, plumbing, HVAC paths; often layout changes (~$200–$400+/sq ft)
Cost per square foot vs room-by-room
Per-square-foot ranges are useful for order-of-magnitude planning. They mislead when wet rooms dominate the spend. A 2,000 sq ft house with a lightly refreshed bedroom wing and a $90,000 kitchen is not “$45 per square foot.” Use this page for the whole-home envelope; build the working budget room by room.
- Price the kitchen as its own project
- Price each bath separately — especially the primary/master bath — and use a bathroom cost breakdown for allocation
- Add systems (electrical, plumbing, HVAC) as house-wide line items
- Add remaining rooms, then contingency, permits, design, and living-during-construction costs
Systems: electrical, plumbing, and HVAC
On a true gut, systems are not optional line items. Opening walls is when you replace aged wiring, update plumbing, and redesign ducts. Systems work moves the project toward the higher end of the $200–$400+ per sq ft gut band. If the roof is also failing, price roof repair or full replacement as its own decision — do not bury a reroof inside an optimistic whole-home average.
- Rewire for modern loads (kitchen circuits, EV charger prep, dedicated laundry)
- Relocate or add baths and kitchen drains
- Replace furnace/AC or heat pump and redesign ducts or refrigerant lines
- Meet current code for smoke/CO, GFCI/AFCI, and ventilation
Example house sizes (illustrative only)
Multiply with care. These examples use planning bands as math checks, not promises. Historic plaster, knob-and-tube, asbestos, lead paint protocols, and hard-to-access crawl spaces push real bids above these illustrations. High-cost metro labor does the same.
- 1,200 sq ft: moderate ~$120,000–$240,000; gut ~$240,000–$480,000+
- 1,800 sq ft: moderate ~$180,000–$360,000; gut ~$360,000–$720,000+
- 2,400 sq ft: moderate ~$240,000–$480,000; gut ~$480,000–$960,000+
Contingency: plan for what the walls hide
Once demo starts, you learn what the previous owner painted over. Water damage, undersized joists, illegal DIY electrical, and mold are common surprises. Soft costs belong in the budget too: architect or designer fees, permit fees, temporary kitchen gear, dumpsters, and post-construction cleaning.
- As a planning rule of thumb, set aside roughly 10–20% of hard construction cost as contingency for a gut
- Use more if the house is old or poorly documented
- Put contingency in a separate line so it does not get spent on upgrades the first week
Occupied vs vacant: living through a gut costs money
A true gut with the family still in the house needs a temporary kitchen, at least one working bath, and dust barriers that actually seal. Vacating for the heavy months is often cheaper than living through a six-month gut once you add hotel or rental, storage, meals out, and lost productivity.
- Replace electrical and HVAC paths before finish floors go down
- Keep one bath online as long as possible; stage bath guts
- Plan a temporary kitchen before demo day
- Decide early whether “while we’re at it” additions are in scope — an addition is a different permit and price band
When $/sq ft ranges mislead
Skip the average — or use it only as a sanity check — when kitchen and baths dominate relative to floor area, you are moving walls, the house needs structural work first, finishes jump to custom millwork and stone, or you are phasing over years (mobilization fees stack).
- Phased work can match cash flow but rarely matches the lowest “all at once” labor total
- Crews remobilize and protect finished areas more than once on phased jobs
How to turn this page into a working estimate
Choose the correct scope label (cosmetic, moderate, or gut). Sketch size × $/sq ft for a ceiling, then rebuild the number room by room. Itemize systems separately from finishes. Add contingency and living/relocation costs. Collect at least three comparable bids with the same written scope.
- Save a phased version in the Renovation Budget Planner if you will stretch work across seasons
