1. Reference the Original Contract
Use the change order number to tie this back to the original estimate or contract. Include the original contract date.
2. List Additions & Deletions
Add new line items for added work. Use negative quantities or prices for removed scope. Be specific about what changed.
3. Explain the Why
Use the notes field to explain why the change is needed — unforeseen conditions, client request, code requirements, etc.
4. Get It Signed
Download the PDF and get written approval before starting the changed work. This protects both you and your client.
When You Need a Change Order
- • The client requests additional work mid-project (adding outlets, upgrading fixtures, extending a deck)
- • You discover unforeseen conditions — rot behind walls, outdated wiring, permit-required upgrades
- • Material substitutions due to supply chain issues that affect the original price
- • Scope reduction when a client decides to cut part of the project
- • Documenting timeline impacts and additional costs required by building code compliance
