Breach of Construction Contract

At a minimum: identification of the parties, scope with plans and specifications attached, price and pricing method, form and schedule of payment, deadline with milestones and penalties, retentions and bonds, a procedure for change orders, permit obligations, acceptance conditions and warranties, and the dispute resolution mechanism. A contract that leaves out change orders and acceptance leaves the two most expensive arguments open.

Document them immediately with a date, photographs and, if possible, a technical report; formally notify the builder; and check where the warranty period stands. The most common mistake is complaining only verbally for months: by the time you decide to act, there is no record of anything and the deadline has moved on.

It depends on the nature of the defect. Defects affecting soundness or compromising the structure carry a long warranty period counted from acceptance of the work; other, minor defects are governed by shorter periods and by what the contract itself agreed. Determining which category the specific problem falls into is the first step of the evaluation.

Yes, although the path differs from collecting between private parties and requires rebuilding the proof of performance and of acceptance. The absence of a formal contract makes the case harder but does not always prevent it. What matters is acting before the administrative deadlines run out.

The mirror-image problem is litigated the same way: with the documentation accumulated during the project. Approved progress billings, records, correspondence and change orders are what prove the work performed. Extensions ordered verbally and later denied are the usual weak point, which is why they should be put in writing while the relationship is still good.
