Can a contractor change the terms of a renovation contract without my consent?

I recently hired a contractor to renovate my home, and we signed a contract that outlined the scope of work, timeline, and payment terms. However, the contractor has now informed me that they want to make changes to the contract, including increasing the cost and extending the timeline. I did not agree to these changes and I'm wondering if the contractor can unilaterally modify the terms of the contract without my consent.

Hi there, No—a contractor cannot legally change the terms of a renovation contract without your consent. A contract is a mutual agreement, and any changes to the scope of work, payment terms, or timeline must be agreed upon by both parties to be valid and enforceable. That said, here is what you should consider: Your Rights as a Homeowner: No Unilateral Modifications Allowed: Contractors do not have the legal authority to raise prices or alter timelines without your express written consent. Any legitimate changes should be presented as a change order—a document detailing the proposed adjustments that you must approve before work continues. Assess Whether the Change Serves Your Best Interest: While unexpected changes can be frustrating, it is important to consider why the contractor is proposing modifications. Sometimes, issues arise during renovation that were not visible or discoverable when the original contract was signed—such as hidden structural damage, plumbing defects, or code violations. In these cases, completing the job correctly may require addressing these issues now, which can impact both the timeline and total cost. Though inconvenient, these adjustments may ultimately benefit you by ensuring the job is done thoroughly and avoids future complications. Contractor Must Clearly Justify the Change: If additional work is necessary, the contractor should be able to clearly explain: What was discovered Why it was not known initially Why the original scope of work cannot be completed without addressing it This explanation should be provided in writing along with an updated scope and pricing breakdown. You Still Control the Agreement: Even if the contractor makes a reasonable request, you are not obligated to accept. You can negotiate the terms, request a second opinion, or consult an attorney before moving forward. You May Have Legal Remedies if the Contractor Proceeds Without Approval: If the contractor insists on changing terms without your consent or threatens to stop work, they may be in breach of contract, and you may have legal grounds to: Withhold payment Terminate the contract Recover costs associated with hiring a replacement contractor A good contractor communicates openly, presents clear documentation, and works with you—not against you. If you need help reviewing the contract or assessing the proposed changes, I would be happy to assist. Best regards, Jerome Lucas Newell, Esq. Home Renovation & Consumer Protection Attorney
