Important Information All of our house plans are designed to include the necessary information you need to build your new home. Please note our plans will not include an architectural or engineering stamp. Some areas will require additional information and/or engineering that can be completed by a local, licensed professional or engineer. We recommend contacting your local building department to find out the requirements specific to your county.

A good start is discussing your plan changes with the mod supplier, checking online reviews, and making sure the timeline set by the modification team meets your requirements.
