What document must a contractor submit to the owner to indicate they will leave the job site if a late payment is not received?

The Stop Work Notice is indeed the appropriate document for a contractor to submit to an owner when indicating that they will cease work on a project due to late payment. This notice serves as a formal notification to the owner that if the payment is not received within a specified timeframe, the contractor will stop all work activities on the job site. This process allows the contractor to protect their financial interests and maintain the right to stop work without violating the terms of the contract.

Submitting a Stop Work Notice provides a clear communication channel between the contractor and the owner, ensuring that the issues surrounding payment are openly addressed. It usually gives the owner a chance to rectify the payment issue before any actual work stoppage occurs, thus maintaining the integrity of the contractor's right to receive timely payment as stipulated in the contract.

Other choices, such as a Notice of Default, typically indicate a failure to meet contract terms but may not specifically address payment issues and do not provide the immediate context of stopping work. A Payment Demand Letter is a request for payment but lacks the formal implication of work cessation. Lastly, a Contract Amendment involves changing the terms of the contract, which is not relevant to the action of stopping work due to payment issues.
