HHI Builders ADU Process in Bluffton & Beaufort SC
At HHI Builders, we strive to provide the best customer service and results through our ADU process. The process includes five steps:


We begin with assessing your property to determine if an Accessory Dwelling Unit (ADU) is feasible for construction. During this step, our design team evaluates the current land and zoning regulations to ensure the construction is allowable.


During this step, our design team will provide a detailed CAD drawing of the proposed ADU with all necessary measurements and specifications. This allows you to visualize how your property will look after completion.


After the design phase is complete, our team will acquire all necessary construction permits. This phase requires patience due to the number of permits involved in building an ADU.


We use only the most experienced tradesmen who specialize in a single trade in order to gain efficiency without sacrificing quality. During construction, we strive to bring your vision to life and ensure it’s done correctly.


Once the construction is completed, our team will finish the ADU with all the necessary features like electrical wiring, plumbing, HVAC systems, flooring, etc. This ensures that your ADU is up to code for your city and state.

At HHI Builders, we understand that building an ADU can be long and complex. That’s why it is important to have a qualified team like ours that understands the process and can help make your dream come true.
