The short answer
Site preparation is the work required to make the property ready for delivery and installation of the home.
Common site work
It may include clearing, grading, drainage, access improvements, foundation preparation, utility connections, septic work, permits, and space for the delivery crew. The exact work depends on the property and installation plan.
Agree on the finished result
A cleared patch of ground is only one part of a prepared homesite. Ask the installer where the home will sit, how delivery equipment will reach it, and which work must be complete before delivery is scheduled.
Have each estimate describe the work, who is responsible, and how completion will be checked. Coordinate the pad, drainage, foundation, and utility locations together. That helps avoid paying for work in one place and then learning that the installation plan requires it somewhere else.
Check readiness before scheduling delivery
Ask who makes the final site-ready decision and how the delivery team receives that confirmation. Keep photographs, contractor updates, and remaining tasks together, but let the responsible professionals decide whether the site is ready. The site-readiness checklist below helps you track access and work at the property so an unfinished task is not discovered only when the home arrives.
