How to Write a Scope of Work That Prevents "I Thought That Was Included"

Most scope disputes do not begin with anyone trying to be dishonest.

The contractor pictured one version of the job. The customer pictured another. Both believed the agreement was clear until the work reached the detail they had never written down.

"Paint the room" becomes a disagreement about ceilings, trim, closets, repairs, and the number of coats. "Replace the furnace" becomes a disagreement about controls, duct modifications, permits, and disposal. "Install new cabinets" becomes a disagreement about hardware, panels, fillers, crown, finish, and touch-up work.

A strong scope of work turns those assumptions into decisions before they become arguments.

What a scope of work is supposed to do

A scope of work should let a person who was not present for the sales conversation understand:

• What the contractor will do.
• Where the work will happen.
• What products and materials will be used.
• What related work is included.
• What the customer must provide or decide.
• What is not included.
• Which drawings, selections, or attachments are part of the agreement.

Wisconsin's home-improvement rules make detail especially important. When Wis. Admin. Code section ATCP 110.05 applies to a written contract, the agreement must clearly set out material terms, including a description of the work and the principal products and materials. Where applicable, the rule calls for the name, make, size, capacity, model, and model year of principal products or fixtures, and the type, grade, quality, size, or quantity of principal building or construction materials.

ATCP 110 does not apply to every residential construction project. Its definition of "home improvement" excludes construction of a new residence and major renovation of an existing structure. The guidance in this article remains useful for writing clear scopes, but contractors should not treat every ATCP 110 requirement as automatically applicable to every job.

That does not mean every scope must read like a technical manual. It means the details that affect what the customer receives should not be left to memory.

Start with clear action verbs

Use verbs that explain the contractor's responsibility.

Useful verbs include:

• Remove
• Protect
• Furnish
• Install
• Repair
• Prepare
• Frame
• Patch
• Prime
• Paint
• Test
• Clean
• Dispose

Weak:

New tile in bathroom.

Stronger:

Remove the existing floor tile in the second-floor hall bathroom. Prepare the exposed substrate and install customer-selected 12-by-24-inch porcelain tile in a straight pattern with standard gray grout. Include perimeter silicone sealant, transition strip at the hallway doorway, and disposal of removed flooring.

The stronger version says what will happen, where it will happen, and what related work is included.

Identify the exact location

"Add outlets" is not enough if the customer expects outlets throughout the first floor and the contractor priced four in the kitchen.

Use room names, elevations, wall locations, cabinet numbers, drawing references, or other clear identifiers.

Examples:

• Install four new duplex receptacles along the west wall of the basement workshop at locations shown on the marked-up plan dated October 2.
• Replace the two double-hung windows on the north elevation of the primary bedroom.
• Install three roll-out trays in pantry cabinet P-3.
• Replace the existing toilet and vanity faucet in the first-floor powder room.

When exact placement will be decided in the field, say who decides and by when.

Final fixture locations will be marked and approved by the owner before rough-in begins.

Use quantities, dimensions, and limits

Words such as "some," "as needed," and "typical" can hide major differences in cost.

Where practical, state:

• Square feet
• Linear feet
• Number of rooms
• Number of fixtures or devices
• Cabinet or window counts
• Opening sizes
• Repair limits
• Number of coats
• Allowance quantities

If the exact quantity cannot be known before demolition, define a base amount and a process for exceeding it.

Price includes replacement of up to 32 square feet of damaged subfloor discovered beneath the existing bathroom flooring. Additional replacement requires customer approval through a change order.

That is clearer than promising to repair "any bad subfloor" without knowing the extent.

Name the principal products and materials

If the product affects price, appearance, performance, lead time, or warranty, identify it.

Depending on the trade, useful details may include:

• Manufacturer and product line
• Model number
• Size or capacity
• Material type
• Grade or thickness
• Color and finish
• Installation pattern
• Hardware type
• Insulation type and R-value
• Roofing or siding profile
• Equipment accessories or controls

For customer selections that remain open, use an allowance or selection deadline instead of pretending the choice has already been made.

Contract price includes a material allowance of $6.00 per square foot for up to 140 square feet of porcelain floor tile. The owner must make the final selection by October 15. Freight, tax, waste, and installation labor are addressed separately in the contract.

An allowance should make clear what the dollar amount covers. Contractors and customers often use the same allowance number while imagining different inclusions.

Describe demolition and existing-condition work

Many scopes describe the new installation and barely mention what must happen first.

Clarify whether the price includes:

• Removal of existing materials or equipment
• Hauling and disposal
• Protection of adjacent finishes
• Temporary removal and reinstallation
• Substrate preparation
• Limited patching or repairs
• Testing before disconnection
• Cleanup after demolition

Also state what cannot be evaluated until the work is opened.

The price is based on visible conditions. Concealed rot, mold, structural damage, code deficiencies, or other hidden conditions are not included unless specifically identified. The contractor will notify the owner and document any proposed additional work before proceeding.

Avoid using a concealed-condition clause as permission to charge whatever appears later. It should create a pause and a process for documenting what was found. When it does, here is what to do when you open a wall and find something unexpected.

Include the work around the work

The main item is usually easy to describe. The disagreement often comes from the surrounding work.

If a plumbing fixture moves, what happens to the wall and floor openings? If recessed lights are added, who handles the ceiling patching and painting? If an HVAC unit changes, are controls, disposal, start-up, or duct transitions included? If a window is replaced, are interior casing, exterior trim, staining, or painting included?

Address:

• Patching
• Painting
• Trim
• Flashing
• Blocking and support
• Access panels
• Delivery and staging
• Start-up and testing
• Disposal
• Protection and cleanup

One sentence about restoration work can prevent a large disagreement at the end of the project.

Separate contractor and customer responsibilities

Write down what the customer must do for the job to proceed.

Common customer responsibilities include:

• Making selections by a stated date
• Providing access to the property
• Removing personal belongings
• Keeping pets away from the work area
• Providing owner-supplied fixtures or materials
• Approving field locations
• Maintaining utilities needed for the work

For owner-supplied products, state who verifies compatibility, handles damage, returns incorrect items, and bears delay costs.

The owner will supply the vanity faucet by November 1. The contractor will install the faucet but is not responsible for product defects, missing components, return shipping, or schedule delays caused by late delivery. Compatibility must be confirmed before installation.

The exact allocation should match your business practice and agreement. The important part is that it is not assumed.

State the exclusions

Exclusions are not an apology. They define the boundary of the price.

Good exclusions are specific to the job.

Weak:

Anything not listed is excluded.

Stronger:

The scope excludes painting outside the repaired ceiling areas, replacement of the existing electrical panel, asbestos or hazardous-material testing and abatement, repair of concealed structural damage, and work in rooms other than the kitchen.

The general statement may still belong in the contract, but project-specific exclusions help the customer understand the real boundary.

Attach and identify supporting documents

Photos, drawings, cabinet plans, finish schedules, product sheets, and marked-up floor plans can make a scope much clearer.

Do not simply exchange files and assume everyone knows which version controls. Identify each attachment by title and date, and state that it is incorporated into the agreement where appropriate.

For example:

The following documents form part of this scope: Kitchen Cabinet Plan, revision 3, dated September 18; Countertop Layout, dated September 21; and owner-approved finish schedule, dated September 22.

Caption job photos so a future reader can understand what each image is intended to show.

Review the scope from the customer's side

Before sending the agreement, ask:

1. Could the customer reasonably expect something that is not written here?
2. Are the most expensive materials and selections identified?
3. Are the quantities and locations clear?
4. Does the scope include demolition, disposal, patching, and finishing?
5. Are owner-supplied items and responsibilities listed?
6. Are allowances defined?
7. Are exclusions specific?
8. Are drawings and photos identified by date or revision?
9. Is there a process for concealed conditions and later changes?

The goal is not to make the scope longer. The goal is to make it harder for two reasonable people to read it differently.

A useful test: Could another crew build from it?

Imagine handing the scope to a competent crew member who never attended the sales meeting.

Would that person know:

• What to remove?
• What to install?
• Where it goes?
• Which materials to use?
• What finish is expected?
• What not to touch?
• Which questions still need customer approval?

If the answer is no, the scope still depends too heavily on conversation and memory.

Where ScopeAccord fits

ScopeAccord lets a contractor describe a job naturally by voice or text, then organizes the information into a professional, reviewable Wisconsin contract workflow.

It is conversationally AI-native at the interaction layer, where it extracts details and helps polish wording. The legal document structure remains deliberately deterministic and counsel-reviewed. The contractor sees what ScopeAccord understood, confirms uncertain information, and approves any wording changes before the document is final.

The purpose is not to replace field judgment. It is to make it easier to turn that judgment into clear paperwork.
