No, engineering is never included with the plan sets. If your building code requires that your plans be stamped by an engineer, you will need to hire someone local to review and stamp the plans. For many coastal areas the foundation sheet will need to be certified by an engineer to meet your specific local building code. This typically includes sizing pilings and beams to meet your wind load requirements as well as determining the appropriate footing for your soil conditions. Keep in mind that you will need to incur this cost whether the plan you use is stock or custom. Depending upon the size and complexity of the design, this fee will typically run between $1,000 – $2,500 or more.
