Quick answer

A restoration change order is a written document, signed by the property owner and the contractor, that changes the agreed scope of work or price after the contract is made, and states what is added or removed, what it costs and how it affects the schedule.

It is a contract tool between you and the contractor. A supplement is a different thing: a request to your insurer for more money. One scope change can lead to both, and they should not be confused.

Quick facts

The key facts about Restoration Change Order, with sources:

What it is
A written, signed change to the agreed scope or price of a job 1
Between whom
The owner and the contractor, under their contract 1
California rule
A price or scope change must be in a written change order signed by both before the change 1
Other states
Contract requirements vary by state; ask for a written agreement even if your state does not require one 3
Not the same as
A supplement, which asks the insurer to pay for damage found later 46
What to see in it
Added or removed work, the price effect and the schedule effect 1
Payment schedule
California says the contract needs a detailed written payment schedule; payments cannot get ahead of the work, except the down payment 1

Key takeaways

  • A change order changes the contract. It should be in writing and signed before the extra work starts.
  • A supplement is a request to the insurer for more money. A change order is an agreement with the contractor.
  • A good change order says what work is added or removed, what the price effect is, and what it does to the schedule.
  • Hidden damage found during demolition is the usual reason scope changes. Ask for photos of what was found.
  • Rules differ by state and by policy. This page is general information, not legal advice.

A restoration change order in plain English

A restoration job starts with a plan: remove wet material, dry the structure, clean and rebuild. The plan is written as a scope of work, with a price. But water damage hides.

Once drywall comes off, the contractor may find wet framing, a second leak or damage that was not visible. The plan has to change.

A change order is the written record of that change. The California Contractors State License Board puts it directly: if the price or scope changes, it must be done with a written change order, signed by the customer and contractor, prior to the change.

Once signed, the change order becomes part of the contract 1.

The word "change order" belongs to the contract between you and the contractor. It says nothing about your insurance. When you also need your insurer to pay for the extra work, the request to the insurer is a separate step, called a supplement.

Not every state uses the same words, and not every job uses a form.

What matters is the substance: a written, dated agreement about what changed, what it costs and when the work will finish, signed by both sides.

The FTC advises asking for a written agreement even if your state does not require one 3.

How a change order works, from discovery to signature

The steps below show the usual order. They describe the general practice; your contract and your state may set different rules.

  1. Discovery. The contractor finds something not in the original scope, such as wet framing behind a wall or a second source of moisture.
  2. Pause and document. Ask the contractor to stop work on that item and photograph what was found. See photo documentation and the moisture log.
  3. Written proposal. The contractor writes up the added or removed work, the price effect and the effect on the schedule.
  4. Your review. Read it against the original scope. Ask what each added line covers, and ask for the same level of detail the first scope had.
  5. Insurer check. If an insurance claim is open, tell the adjuster about the new damage. Texas guidance says to raise other damage a contractor found with your insurer 4.
  6. Sign before the work. Both parties sign and date. California treats the change order as part of the contract once signed 1.
  7. Keep a copy. File the signed change order with the contract, the photos and the invoices.
Process From hidden damage to a signed change
  1. FoundExtra damage or a scope gap appears
  2. DocumentedPhotos and readings of what was found
  3. ProposedWritten scope, price and schedule effect
  4. ReviewedYou compare it to the original scope and tell your insurer
  5. SignedBoth sides sign before the work starts

The sequence is general practice. The signed step before the work is the one California requires of home improvement contracts 1. Source: [1] [4]

Verbal "go aheads" on site are the weak point. A spoken yes leaves no record of what was agreed or what it cost.

Kinds of scope changes you may see

The categories in this table are common ones, not an official list. Each should be written down.

Change order or supplement?

A change order asks you and the contractor to agree. A supplement asks your insurer to pay. Texas guidance describes the second: show the contractor your insurer’s estimate, and if the contractor finds other damage the adjuster missed, raise it with your insurer 4. You may need both for one scope change.

Example: how a change order adds up, with symbols instead of prices

We do not publish restoration prices. This example uses letters so the structure is clear. It is an illustration of the arithmetic, not a real job, and the amounts are never typical figures.

LineItemHow it is written
1Original agreed priceA, from the signed contract
2Added work found behind a wall+ B, with the scope described and photographed
3Work dropped because the area dried in place- C, as a credit
4New total after the change orderA + B - C
5Schedule effectNew completion date written, or "no change"
6Insurance effectTell the insurer about line 2, and ask what it will cover. Your deductible does not repeat, and the policy decides coverage.
Formula How the total changes

New contract price = Original price + Added work - Removed work

Original price
The total in the signed contract
Added work
Lines written and signed in the change order
Removed work
Credits for tasks dropped

The formula is arithmetic only. Whether an insurer pays any part of it depends on your policy.

A change order that shows only a new total, without lines 2 and 3, hides what moved. Ask for the build-up.

Where change orders show up in a restoration project

During demolition. Demolition is one common moment. Once drywall, flooring or insulation comes off, the contractor sees the real extent of the damage.

Between drying and rebuild. A move from mitigation to reconstruction can bring a new scope. See how restoration works and reconstruction for how those phases differ.

On the invoice. A final bill that is higher than the first estimate should be explained by signed changes. Our estimate checker helps you read the lines.

In the insurance file. The adjuster may ask for the contractor’s written scope and any additions. Read working with an adjuster for how that exchange goes.

At closeout. A final walkthrough compares finished work to the scope plus every signed change. See post-restoration inspection.

What a written change order protects, and what it does not

What it protects

  • Gives both sides the same written account of what was agreed.
  • Shows the price effect before the work starts, not after.
  • Becomes part of the contract in California once signed 1.
  • Gives your insurer something specific to review.
  • Helps you check the final invoice against what was approved.

What it does not do

  • It does not make the insurer pay. Coverage comes from the policy.
  • It does not fix a vague original scope.
  • It does not replace the paperwork for a permit if the new work needs one.
  • It does not guarantee the contractor’s price is fair; compare it with your own check.
  • It is not a substitute for advice from a licensed attorney in your state.

Limits of this explanation

The rules for change orders differ by state, by contract and sometimes by the type of work.

The strongest public statement we found is from California, whose licensing board says a change must be written and signed by both parties before the change 1.

We did not verify the rule in every state, and we cannot say what your state requires. The FTC says contract requirements vary by state 3.

A change order also depends on what the original paper said. A vague scope makes every later change harder to judge. See restoration contractor and the guide to choosing a company for what to expect in the first document.

Finally, no licensed attorney or insurance professional has reviewed this entry. Treat it as a general explanation, not advice for your case.

Source and scope

California and Texas sources are cited here as examples of what a state regulator says. They do not bind other states. Your contract and your policy control your case.

What drives the price effect of a change order

We publish no prices for restoration work. A change order carries a price because the scope changed, and several things push that price. How much extra material is affected is the first.

How hard it is to reach is the second, since hidden damage behind finished surfaces takes more labor. Whether new equipment or a new method is needed is the third, as when drying switches to removal.

Time is the fourth. Added days can mean added equipment days, which show up on the invoice. The drying log is the check on that.

Use the restoration cost guide to see what moves a total, and the deductible calculator to see how your deductible fits. The Texas guidance reminds homeowners that if they use their own insurance, the deductible is subtracted from the payment and is owed to the contractor 4.

A change order has no warranty of its own. It becomes part of the contract, so any workmanship warranty in the contract applies to the added work. Read the warranty terms to confirm.

How to handle a proposed change, step by step

You are not obliged to accept a change on the spot. Taking a day to review is reasonable unless the delay itself would cause more damage, and the contractor can tell you if it would.

  1. Ask the contractor to explain what was found and to show photos.
  2. Ask whether the delay of a day would cause more damage, and in what way.
  3. Ask for the proposed change in writing, with added work, removed work, price effect and schedule effect.
  4. Compare it with the original scope. Check that nothing is counted twice.
  5. Tell your insurer, and ask the adjuster whether it needs to see the contractor’s written scope. Your contractor can discuss costs directly with the adjuster 5.
  6. Get a second opinion on a major change if time allows. Texas advises getting estimates from more than one contractor, and California advises written bids with line-by-line prices 46.
  7. Sign only when you understand it. Do not sign a document with blank spaces 34.
  8. File the signed copy with the contract, photos and invoices.

Keeping the paper trail

A change order is only useful if you can find it six months later.

  • One folder for all changes. Number them in order and file each with its photos.
  • Match changes to invoices. Each invoice line that is not in the first scope should point to a signed change.
  • Keep your call log. The California guide advises a log of calls and copies of correspondence 6.
  • Ask for payment releases. The California licensing board advises getting a signed conditional lien release before each payment and an unconditional release from each claimant paid afterward 2.
  • Keep the file after closeout. You may need it for a sale or a later claim.

Warning signs around a change order

  • Work starts before paper is signed. A verbal approval is hard to prove later.
  • A change with no photos. Ask what was found and where.
  • A new total with no lines. You cannot check what you cannot see.
  • Pressure to sign at once, with no reason given. Ask what harm a short delay would cause. See avoiding restoration scams.
  • A blank space on the form. The FTC and Texas both advise against signing a document with blank spaces 34.
  • Large payment demanded with the change. The Texas guidance says not to pay the full amount upfront 4.

Safety and risk

If new damage includes sewage, visible mold, a sagging ceiling or a damaged electrical or gas line, work in that area should stop until it is made safe by a qualified professional. Do not sign a change order that sends workers into an area you believe is unsafe.

Is a written change order required? Law, standard and contract

Law. This depends on your state. California’s licensing board says that if the price or scope changes, it must be done with a written change order signed by both parties before the change, and that the contract should identify the contractor’s license number and have a detailed written payment schedule 1.

The FTC says contract requirements vary by state and advises asking for a written agreement anyway 3. NASCLA’s directory lists state licensing rules 9. We did not verify other states.

Standard. The IICRC’s water damage standard covers project documentation and risk management as topics 8. It is voluntary, it is not a law and it is a paid document we have not reviewed in full.

See the S500 entry and the overview. One university guideline shows how an institution can bind scope changes: it requires a signed job form from the contractor before work starts or before any change in scope 7.

Contract and policy. The contract sets what counts as a change and how it is approved. Your policy sets what the insurer will consider. Read both. This is general information, not legal advice.

Common change order myths

Myth A change order and a supplement are the same.
Reality They are not. One changes your contract with the contractor. The other asks the insurer to pay 14.
Myth If the insurer approved the claim, the contractor can add work freely.
Reality The contract still governs. California says the change must be written and signed before it is made 1.
Myth A spoken "go ahead" is enough.
Reality It is hard to prove what was agreed. Ask for it in writing, even if your state does not require one 3.
Myth A change order raises the price.
Reality It can add, remove or only change the schedule. Removed work should reduce the total.
Myth I have to sign on the spot.
Reality You can ask for time. Ask what harm a short delay would cause, and get the answer in writing if you can.

What varies by state: contract rules and licensing

Written-contract and change-order rules are set state by state. California’s board requires a written, signed change before the change 1. The FTC says contract requirements vary by state 3.

Whether restoration work needs a contractor licence also varies, and NASCLA’s directory lets you compare states 9. Check your state’s contractor licensing board and consumer protection office for the rule that applies to you.

When to push for a written change order, and your next step

Push for one any time the work, the price or the date changes and you are paying for it, directly or through a claim. The bigger the change, the more it matters.

Your next step is to ask the contractor, before work starts, how changes will be approved. Put the answer in the contract. Then keep a file for changes as you go.

Decision guide Change order decision guide
If New damage is found during demolition
Then Ask for photos, a written proposal and tell your insurer before you sign
If The contractor asks for a verbal go-ahead
Then Ask for it in writing before the work begins
If The new total has no lines
Then Ask for the added and removed work separately
If Visible mold or sewage appears
Then Stop work in that area and ask for a separate safety plan

Questions about Restoration Change Order

What is a change order in restoration?

A change order is a written, signed document that changes the agreed scope or price of a restoration job after the contract is made.

It states what work is added or removed, what it costs and how it affects the schedule.

California’s contractor licensing board says it must be signed by both the customer and the contractor before the change.

What is the difference between a change order and a supplement?

A change order changes your contract with the contractor. A supplement asks your insurer to pay for additional damage or cost. Texas guidance says if a contractor finds other damage the adjuster missed, you raise it with your insurer. One scope change may need both, and they follow different rules.

Does a restoration change order have to be in writing?

It depends on your state. California says price or scope changes must be made with a signed written change order before the change. The FTC says contract requirements vary by state, and advises asking for a written agreement anyway. Check your state’s contractor licensing board.

What should a change order include?

It should name the added or removed work, the price effect, and the schedule effect, and be signed and dated by both sides. California’s board says the contract should also name the contractor’s license number and give a detailed written payment schedule. Ask for photos of any hidden damage that triggered the change.

Why do restoration scopes change mid-job?

Water damage can be hidden. Once walls or floors open, a contractor may find wet framing, a second source of moisture or damage that was not visible. A change in method, such as removing a material that cannot dry in place, can also change the scope. Ask for photos and readings of what was found.

Do I have to tell my insurer about a change order?

If a claim is open, tell your insurer about new damage. Texas guidance says to raise other damage the contractor found with your insurer, and the California guide says additional damage found later may be reported to reopen a claim. Your policy may set its own duties, so read it.

Can I refuse a proposed change?

Yes, you can ask questions, ask for time and get a second opinion. Ask whether a short delay would cause harm and why. Do not sign a document with blank spaces. If the change is needed for safety, such as removing a contaminated material, ask for the reason in writing.

What if the contractor started work before I signed?

Stop and ask for the change in writing. A spoken approval is hard to prove later, and in California a change must be written and signed before it is made. Photograph what has been done, keep your notes and contact your state licensing board or an attorney if there is a dispute.

Does a change order change my deductible?

No, not by itself. The Texas guidance says that when you use your own insurance, the deductible is subtracted from the payment and is owed to the contractor. A change order changes the scope or price. The deductible is set by your policy, so check it and use the deductible calculator.
