Detached ADUs are standalone backyard homes built separately from the main house. These are one of the most popular choices for homeowners who want maximum privacy and long-term value.
Typical detached ADU sizes in Redondo Beach:
400–600 sq ft studio or 1-bedroom
700–850 sq ft larger 1-bedroom or 2-bedroom layouts
Up to 1,200 sq ft depending on the property and city regulations
Detached ADUs offer:
✓ Better privacy
✓ Higher rental potential

3. Attached ADU
Attached ADUs share a wall with the main home while still functioning as a separate living space. These work well for homeowners wanting to expand usable square footage while maintaining privacy.
