Generally, plans for construction work involving single family dwellings are not required to be prepared by an architect or engineer, however, some special features not covered by the prescriptive requirements of the codes may require a design to be prepared by a Kansas Registered Design Professional.
Some of the special features that may require plans to be sealed by a licensed professional:
• Walls that are subject to hydrostatic pressure from groundwater;
• Retaining walls that will support fill with a depth of 4 Feet or more;
• Foundation walls exceeding 9-feet in height;
• Footings and foundations that are placed on fill;
