What Is a Change Order? How Remodeling Changes Work in San Jose
A change order is a written change to your remodeling contract. For a remodel in San Jose or anywhere in California, CSLB says any change to the contract price or scope must be made with a written change order, signed by you and the contractor before the change, and it then becomes part of the contract.
Many remodels change along the way: a different tile, a moved outlet, rot found behind a wall. What matters is that each change is written down, priced, and signed before the work.
Why change orders happen
- You change a layout, fixture, material, or feature
- Demolition uncovers a hidden condition, such as water damage or old wiring
- A design detail wasn’t settled before the contract
- A product is discontinued, delayed, or doesn’t fit
- An inspector or a field condition requires a change
What a change order should include
- What is changing and why
- The price added or taken off
- How it changes the payment schedule
- How it changes the schedule
- Any new exclusions or assumptions
- Signatures from you and the contractor, dated before the work
How much can a contractor go over an estimate?
An estimate isn’t the contract, so first ask which number you are looking at. A preliminary range or a ballpark is only a starting point. Once a home improvement contract is signed in California, CSLB says any change to the price has to go through a written change order, signed by you and the contractor before the change. So the contract price should move only when both of you have signed for it.
At Landford Construction, the preliminary range from photos isn’t a final estimate. The written proposal gives one price for the agreed work, and anything beyond that goes through a signed change order.
When hidden conditions show up
Ask the contractor to show you the problem, explain the fix, and give you the price and schedule effect before the work goes ahead. Photos of the condition make the record clear for both sides. A separate reserve in your budget makes these decisions easier.
Landford’s Los Gatos warehouse renovation included replacing a leaking sewer line. Work like that is the kind of item to document and price before it goes ahead.
How to keep changes to a minimum
Late decisions are a common source of changes. Pick tile, cabinets, appliances, plumbing fixtures, and lighting before work starts, and check that the proposal lists every item as included, excluded, or an allowance. If a price assumes the existing plumbing can stay, that assumption should be written down.
Don’t approve changes out loud
A quick yes on site is easy to misremember. Put the decision, the price, and the schedule effect in writing first. One change can affect several trades, so ask what else it touches.
How Landford Construction handles changes

The bottom line
A remodel will change along the way. Keep every change written, priced, and signed before the work, and it stays a decision instead of a dispute.
