How to write a contractor scope of work
The short answer
A usable scope says what will be removed, prepared, installed, tested and cleaned; identifies materials and quantities; allocates permits and disposal; lists exclusions; and defines completion. Give the same scope to every bidder, attach the agreed version to the contract, and require written change orders for deviations.

Describe the result and responsibility
Record existing conditions, demolition, preparation, installation, testing, protection, cleanup and restoration. Name products by brand, model, grade, color and quantity where they matter. For allowances, state the amount and who pays any difference.
Assign permits, inspections, utilities, access, hazardous-material testing and disposal. List exclusions conspicuously rather than leaving them implied.
- Site and work areas
- Materials and approved substitutes
- Permit and inspection owner
- Protection, cleanup and disposal
- Start, milestones and completion
- Closeout documents and warranties
Attach it and control changes
Attach the dated scope to the signed contract. California’s licensing board tells consumers to put additions or changes in written change orders. Your state may require different contract language, notices and signatures.
