How much does a structural engineer cost for a residential house plan?

Cost varies with the size and complexity of the house, the soil conditions, the number of drawings, and how many site visits or inspections are included. Do not rely on a figure from an article. Ask for a written fee proposal that states the drawings and certificates included, whether footing and frame inspections are included, how revisions are charged, and when payment is due. The engineer will normally need your soil report and the architectural plans before starting, so engage the geotechnical engineer first.

In MyBuildHub: add the engineer as a budget line, store their drawings in your project documents, and set Timeline dates for their deliverables so the certifier is not waiting on them.

Check yourself: your certifier for what engineering they need, and your state building regulator.
