Plan Your Remodel What it costs

The short answer
A gut renovation strips a room, a floor or a whole house down to its framing, removing finishes, drywall or plaster, and usually old wiring, plumbing and ductwork, then rebuilds.
Because the walls are open, what was hidden becomes part of the job: lead paint or asbestos in old materials, wiring and pipes that must meet current code, damaged framing, and alarm upgrades that permitted alterations trigger.
A gut renovation is planned around testing first and a contract that prices discoveries.
What decides a gut renovation?
Old paint, plaster, flooring and insulation may contain lead or asbestos; both have federal rules on how they are disturbed.
Once systems are replaced, they are inspected as new work. The existing building code covers how much of the rest must be upgraded.
The contract needs a way to price rot, undersized framing and old repairs before demolition finds them.

When a gut renovation makes sense
Reasons to strip to the studs instead of remodeling around what is there.
Knob-and-tube or ungrounded wiring, galvanized supply pipes, or failing drain lines throughout.
Moving kitchens, baths and walls means opening most surfaces anyway.
Wet or smoke-damaged materials have to come out.
If systems are sound, a whole-home renovation that keeps walls may be the better scope.
What does a gut renovation include?
The sequence once the house is open. Each covered step is usually inspected before the next one hides it.
Hazardous-material testing, measured drawings and a permit application.
Abatement by certified firms where testing found hazards, then strip-out to framing.
Repair rot, add or replace headers and beams, and fix anything the drawings change. Structural work needs an engineer’s design where your building department requires it.
New wiring, plumbing, ductwork and ventilation, then the rough-in inspection.
Open walls are the cheapest moment to insulate and air seal; energy code applies to new work.
Drywall, flooring, cabinets, tile, fixtures, trim and paint, then final inspection.
Which codes apply when a house is gutted?
Model-code sections that come up on a gut. Local adoption and amendments decide the details; your building department confirms them.
Many jurisdictions apply the International Existing Building Code to alterations; its level of alteration sets how much of the house must be brought up to current standards. See existing building code.
2021 International Residential Code sections R314.2.2 and R315.2.2 require alarms in existing areas when alterations need a permit.
New circuits follow the NEC edition in force, including AFCI and GFCI requirements.
Newly exposed walls and ceilings usually must be insulated to the current energy code when they are rebuilt.
What hazardous-material rules apply to a gut renovation?
These are federal rules on disturbing old materials. Have testing done by a qualified inspector and the work done by certified firms; this page gives no removal instructions.
In homes built before 1978, paid renovation that disturbs painted surfaces falls under the EPA Renovation, Repair and Painting Rule (40 CFR Part 745, Subpart E): a certified firm and lead-safe practices.
Older insulation, flooring, plaster, joint compound and pipe wrap may contain asbestos. The EPA advises leaving suspect material undisturbed until tested, and removal by trained professionals. State and local rules may require a survey before demolition.
Wet framing found in demolition must be dried and the moisture source fixed; see EPA mold guidance.
What changes the budget of a gut renovation?
No figures here, by policy: see what drives a remodeling budget and the whole-home budget tool. The lines that move a gut:
| Factor | Why it changes the number |
|---|---|
| Testing and abatement | Unknown until tested. Get the test before the contract. |
| Structural repair | Rot, sagging or undersized framing found only after demolition. |
| Systems replaced | Electrical, plumbing and HVAC replaced versus reused. |
| Living elsewhere | Most owners move out for a whole-house gut; rent and storage belong in the budget. |
| Contingency | A dedicated line for discoveries, set before demolition. |
HyreRemodel publishes no national average price for this work. Size, finish level, whether plumbing, wiring or walls move, the age of the house and regional labor rates move it far enough that a single figure would mislead.
Have the old materials been tested?
If not, test before you collect bids, so every bidder prices the same abatement and the contract does not open with a surprise. If they have, attach the report to the bid package.

Primary-source research, data analysis and fact checking
We are a research desk, not a remodeling contractor and not a sales floor.
We read the statute, the licensing register or the municipal fee schedule ourselves, and we publish the figure with the document it came from and the date we retrieved it.
Where a number cannot be traced to a primary source, we publish the shorter page and say what we could not verify.
This program is new, and the counts below are small: they are what we have actually published, not what we intend to.
- 7
- studies published
- 7
- states in the contractor store we measure against
- 264
- source documents linked from these pages, 101 of them on .gov domains
- 22,183
- license records measured September 5, 2026
How this desk works
- Primary sources only. Licensing facts come from the issuing board or the statute that creates the credential. Permit-fee facts come from the municipality that publishes the schedule. We do not cite an article that cites a source; we open the source and record the date.
- Our own store is titled to the states it covers. We hold verified contractor records for seven states. An asset that rests on those records is titled to those states. National claims rest on federal or state-agency data (Census, BLS, EPA), never on our counts.
- Absence of a record is not a finding about the company. A board that does not publish disciplinary history in a form we retrieved is excluded from any “clean record” claim. Unable to verify is not unlicensed. Not required is not not carried.
- Fact, calculation, analysis and recommendation stay labelled. A statute is a source fact. A count we derived from our store is a HyreRemodel calculation. What that count means is analysis. What a homeowner should do next is a recommendation.
- We do not remodel homes, and we take no payment for placement, ranking or a favorable mention. Nobody buys a position on this site.
Authorship on this site is organizational: the analysis belongs to the desk rather than to a named individual, and we do not publish credentials we do not hold. Our editorial policy sets out how we source, date and correct what we publish.
