Free Construction Change Order Template (2026 Word, PDF, Google Doc)

Field 1: Change description (specific scope of work)

First, write exactly what is being added, removed, or modified. Specifically, vague language sinks change orders. For example, “Move sink” is not enough. Instead, write “Relocate kitchen sink 28 inches east, including new drain line, new supply lines, and patch and paint of vacated wall location.” In addition, attach photos, sketches, or the marked-up plan if it helps. As a result, the more specific the description, the harder it is for the client to claim later that the work was not what they thought.

Cost impact, line by line (not a lump sum)

Specifically, do not write a single number. Instead, break out labor, materials, equipment rental, and markup as separate lines. For example, “Plumber labor: $420. Materials (PEX lines, drain fitting, sink valve): $185. Drywall and paint: $150. Markup 20 percent: $151. Total: $906.” Then state whether the change is a credit (subtract) or a charge (add). Generally, this level of detail is what gets clients to sign without a 45-minute negotiation about “what does that really cost.”

Field 3: Time impact (days added to the completion date)

Notably, the schedule impact is the single most overlooked field on a change order. In fact, contractors price the labor and materials, then forget to add days to the completion date. As a result, the homeowner gets to claim the contractor is “late” on the original deadline. Specifically, write “+ 2 working days, revised completion date April 26, 2026.” In particular, if the change has zero schedule impact (rare but possible), write “0 days, no schedule change.” Therefore, address the time impact every time, even if the answer is zero.

Original contract reference (date, PO number, project name)

First, every change order must point back to a specific original contract. Specifically, list the contract date, the project name, the property address, and the contract amount before the change. In addition, number the change orders sequentially (Change Order 1, 2, 3) so the running total is obvious. As a result, when the client gets the final invoice, the math reads straight from the contract plus each numbered change order in order.

Field 5: Signature lines (client and contractor, both dated)

Notably, an unsigned change order is not enforceable in most jurisdictions. Specifically, you need both the client signature and the contractor signature, both dated, both before the extra work starts. In addition, if the property has multiple owners (married couples, business partners), get every owner who signed the original contract to sign the change order. Generally, electronic signatures via DocuSign or HelloSign are valid in all 50 states under the federal ESIGN Act and the Uniform Electronic Transactions Act (adopted in every state except New York, which has its own equivalent law).

Revised contract total (running balance)

Finally, every change order ends with one number: the new total contract amount. Specifically, write it as “Original contract: $48,400. Prior change orders (1 through 3): $2,820. This change order (4): $920. Revised contract total: $52,140.” In addition, this running balance protects you on the final invoice and shows the client exactly where each dollar came from. As a result, transparent math is what stops the “I never agreed to that” fights at the end of the job.

Step 1: Capture the change at the moment it comes up

First, when the client says “Hey, can we also…” or you uncover a hidden condition, stop and write it down before doing anything else. Specifically, snap a photo, note the location, and quickly sketch what the new scope looks like. In addition, do not start the work on a verbal handshake. Notably, contractors lose more money to “I’ll throw it in” agreements than to any other single mistake on a remodel.

Fill out the change order template the same day

Then, within 24 hours of the scope change, fill in all six fields on the template. For example, write the scope description, price the labor and materials line by line, state the time impact in working days, reference the original contract by date and amount, and prepare both signature lines. In addition, use the SimplyWise Cost Estimator to price the change from a site photo in seconds. As a result, you turn a 30-minute pricing exercise into a 10-second one.

Step 3: Get the signature before the extra work starts

Specifically, this is the non-negotiable step. In fact, California Business and Professions Code section 7159 makes it explicit: a change order is “not enforceable against a buyer” unless signed in writing before the work begins. As a result, send the template by email with a DocuSign link, or print and sign on the job site. Therefore, only after both parties sign do you order materials, dispatch the crew, or pour the first cubic yard of extra concrete.

File the change order and bill on the next draw

Finally, save the signed change order alongside the original contract in your project folder. Then bill the change order amount on the next scheduled draw, not at the end of the job. Generally, contractors who hold change orders for the final invoice end up fighting over $4,000 in scope changes the client forgot they agreed to four months ago. In summary, bill it fresh, bill it itemized, and the client pays it the same way they pay the rest of the contract.

Mistake 1: The “I’ll throw it in” verbal handshake

Generally, the client asks for a small addition (move an outlet, swap a fixture, add a shelf), and the contractor says “no problem, I’ll throw it in.” Then the contractor forgets, runs over budget, and tries to bill it. Notably, the client has no record of agreeing. As a result, the contractor eats the cost or fights to collect on something with zero paper. Therefore, every scope change goes on a change order, even if you decide to charge zero.

Billing the change order weeks after the work

In particular, contractors do the extra work, then save the billing for the final invoice. Specifically, by the time the client sees a $3,800 line for changes, they have forgotten three of them and dispute the rest. As a result, the contractor either negotiates down or sends the file to a lien attorney. Therefore, bill every change order on the next scheduled draw, not at the end.

Mistake 3: No signature, no enforceable contract

Specifically, California makes this rule a statute (BPC section 7159), but the underlying common-law principle applies in most states. In fact, courts in Texas, Florida, and New York have all enforced the rule that an unsigned scope change is hard to collect on. As a result, no signature means the change order is a document the client can simply refuse to honor. Therefore, get both signatures, both dated, before the extra work starts.

Pricing only materials, not the time impact

Notably, the schedule impact is what most contractors leave off the change order. For example, a wall removal that takes an extra 2 days pushes the completion date by 2 days, but if the change order does not say so, the client gets to call you late on the original deadline. In addition, late-completion penalties can run $100 to $500 per day in commercial contracts. Therefore, state the days added every time, even if it is zero.

Build a change-order-prone line into the original bid

Generally, the items that cause most change orders are hidden conditions: rotted subfloor under tile, undersized electrical service, asbestos popcorn, knob-and-tube wiring, mold behind drywall. Therefore, add a “Hidden Conditions Allowance” line of $500 to $2,500 to the original estimate. As a result, when you uncover something, you draw from the allowance instead of writing a panic change order.
