Unless you have prior construction experience, you’ll need to consult an architect to design your new unit. They will have all the tools at their disposal to design a living space that meets state and local requirements. 

However, if you are equipped to design the unit yourself, there are several things to keep in mind. First, an ADU must include four elements: a place for sleeping, eating, cooking, and sanitation. Make sure your design comports with the siting and feasibility analysis that you have already done. Next, you will need to ensure your ADU complies with either Vermont’s or New Hampshire’s state building code, depending on your local jurisdiction (see PERMITTING).

Here is a link to many different ADU floor plans. Bear in mind that the final design of your ADU may be subject to change as you go through the construction and finance processes. You may also wish to consider purchasing ready-made ADU building plans or even a prefabricated, standalone ADU that can be installed on-site. Wheelpad and Backyard ADUs have many prefabricated homes and designs for you to peruse.

Your final design will help you determine how much money you need to execute the project.
