What a Basement In-Law Suite Must Include
An accessory dwelling unit (ADU) or in-law suite in a basement must function as an independent living space. It typically includes a separate entrance, bathroom, kitchen area, and sleeping quarters. For basements, meeting egress standards is critical to ensure safe exit routes in emergencies. Our experience focuses solely on basements, which means we prioritize basement-specific challenges like moisture control, ceiling height, and natural light.
