Change Orders: How Scope Changes Should Be Handled

Before you sign a contract, settle one thing: what happens when the job changes. It will change. Your contract describes the project as it was understood the day it was written, and construction has a habit of revealing what nobody could see. Agree on the process in advance, rather than negotiating it in a hallway while a crew waits on an answer.

A change order is a written amendment to your contract. It records what changed, what it costs, what it does to the schedule, and that both parties agreed before the work happened. California regulates home improvement contracts, and written change orders signed by both sides are the standard we work to. We are contractors, not attorneys, so confirm what applies to your contract with the CSLB or with an attorney of your own.

Why they happen even on well planned projects

Some change orders come from sloppy planning. Most do not.

Concealed conditions. Opening a wall turns up dry rot, a drain line that is not where the drawing says it is, old wiring, or framing carrying more load than expected.
Inspector direction. An inspection can require something the approved plans did not call for. Not optional, and not the contractor's mistake.
You changed your mind. Standing inside a framed room changes how people feel about a window.
Material availability. Tile gets discontinued. A fixture slips to a long lead time and a substitution has to be priced.
Design gaps. Drawings never cover every detail. Midway through, a decision nobody wrote down has to be made and paid for.

How many change orders a job has matters less than how they were written. Four documented changes you approved beats zero change orders and an invoice that somehow grew.

What a fair one looks like in writing

A plain description of the change, specific enough that someone who was not there could understand what was done
The reason it came up: a discovery, an inspection item, or your own request
Cost broken into labor and materials rather than a single figure
Schedule impact stated in days, including zero days when there is none
Revised contract total after the change is applied
A credit line when something is being removed from the original scope
Date and both signatures, dated before the work begins

Pay attention to that credit line. Changes run both directions. Drop a scope item and the money should come off the contract in the same document, priced like an addition.

How verbal changes turn into billing disputes

The pattern is boring and predictable. You are standing in the garage and you say, while you are in there, could you also move that outlet. The lead says no problem. Nobody writes anything down. Seven weeks later a line appears on the final invoice. You remember a favor. He remembers extra labor and a trip to the supply house.

Neither of you is lying. Two people recall a hallway conversation differently, which is why the writing requirement exists. Once an amount is disputed and nothing was signed, you are arguing about memory, and that argument costs more in goodwill than the outlet was worth.

Set a rule with your contractor and hold both sides to it. If a change costs money or adds days, work does not start until something is signed. Text and email beat a conversation, though a signed change order is the standard to ask for.

Settle these before you sign the original contract

Approval authority. If two of you own the house, name one person who signs, so nobody performs work on a maybe.
Turnaround. How fast will the contractor price a change, and how fast will you answer.
Markup policy on change order work, described in the contract rather than explained later.
Allowances. Going over an allowance is not the same event as a change order, and the contract should say how each gets billed.
Declining a change. Ask that the contract spell out what happens if you turn down a proposed change, including the effect on schedule, and have an attorney review that language before you sign.

Keeping a change from stalling the job

Speed matters more than most homeowners expect. A crew waiting on a decision gets moved to another site, and pulling them back takes longer than the delay you caused. The rhythm that works is simple. Your contractor prices the change the same day or the next, you answer quickly, work resumes. Ask for photographs of anything found behind a wall. A picture of the rot settles whether the change was real.

What to expect from us

Written scope before demolition starts. Changes priced in writing and approved by you before the work happens, so nothing reaches your invoice that you have not already signed. Open a wall, find a problem, and you get the photo and the explanation before you get a number. Our license is CSLB #1063782. Verify it yourself at cslb.ca.gov.
