Renovation extras and disputed change orders

Disputes about renovation extras often turn on what work was authorized and how the price changed. Preserve the original scope, estimate, contract, change orders, messages, and payment records. Identify who requested each change and what was agreed about cost and timing.

A contractor's invoice and a homeowner's recollection may tell different stories. Compare them against the contemporaneous documents. Applicable consumer protection rules can affect estimates and unauthorized charges, but the legal treatment depends on the agreement and transaction. A useful damages worksheet separates original work, accepted extras, disputed extras, and credits. Construction lien or trust issues may require a lawyer even where a smaller monetary claim could otherwise fit Small Claims Court. Obtain advice before evidence is altered by further work.

Create a change schedule with one entry for each alleged extra. Identify who requested it, when the request was made, what work changed, the price discussed, and the record supporting authorization. Distinguish a genuine scope change from work already included in the original bargain. A message agreeing to a different material may not settle every question about labour or delay costs. Keep drawings, product selections, and progress photographs where they help explain what the parties actually discussed.

For a homeowner, the key preparation is evidence of the accepted scope and response to later requests. For a contractor, it is evidence of authority and agreement before the extra work proceeded. Neither side should assume the final invoice resolves a disputed approval. Compare the contractual terms with applicable consumer rules and preserve any issue involving an estimate or unauthorized charge for specific review. If liens, trust claims, or urgent construction deadlines are implicated, obtain lawyer advice promptly. A transparent separation of agreed and disputed work can narrow settlement discussions substantially.
