Across the state, including the metro areas of Montgomery and Mobile, the climate influences material choices and project timelines. We guide you through the process, focusing on the practical steps to add an ADU to your property.

Choose your city

In Alabama, the humid subtropical climate means that material selection is key to long-term durability. Wood framing requires proper sealing and ventilation to prevent moisture issues, especially in coastal areas like Mobile. The state's permitting process generally involves local planning departments, with requirements varying by municipality. Focus on understanding the specific zoning ordinances in Montgomery or your city of residence to ensure your ADU plans align with local regulations.
