Chattanooga has approved 97 accessory dwelling units in the roughly two years following its 2022 ADU ordinance. Converting a garage, basement, or similar space into a livable ADU raises electrical questions that a typical renovation wouldn’t.
An ADU conversion often means the new space needs its own circuits, separate from the rest of the home, and enough capacity for appliances, lighting, and everyday use. Whether the space needs a subpanel or can run off the existing panel depends on your home’s current setup — an independent provider can evaluate this directly rather than assuming a standard answer applies.
It’s also worth checking with the city on any permit requirements tied to your specific ADU project, separate from the electrical work itself.
