Most ADU experts recommend between 650 and 800 sq ft to achieve a perfect balance of privacy, storage, and spacious living.

Local height regulations usually range between 16 to 24 feet or higher, accommodating two-story designs. Popular layouts often feature a primary bedroom with deck for added appeal.

In residential properties, including an ADU house, occupancy standards may vary based on specific ADU types, especially if a larger primary bedroom is included. Always confirm with your local housing authority or property manager to ensure compliance.

Always confirm local code requirements related to setbacks, height, and lot coverage with your city or county planning department.
