What documentation should builders keep for at least four years after project completion?

Builders should keep contracts and change orders for at least four years after project completion because these documents serve as vital evidence of the agreements made with clients and any changes that occurred throughout the project's duration. Contracts outline the terms, responsibilities, and expectations, while change orders record modifications to the initial agreement, including adjustments in cost, scope, or timelines. Retaining these documents provides protection in case of disputes or legal matters regarding the project, as they clearly detail the obligations of both parties and any agreed-upon alterations. This timeframe aligns with typical statutes of limitations for contract disputes, ensuring builders have necessary documentation available should any issues arise long after the work is completed.

In contrast, while invoices and scheduling plans, employee time cards and payroll records, and site photographs and blueprints are important, they do not hold the same level of legal significance regarding contract enforcement and disputes. Each serves its purpose in project management but is not typically required to be kept for as long as the contracts and change orders.
