Before design begins, get clear on what success looks like. Ask:

• Is the primary goal rental income, family use, or lifestyle space?

• Do you want long-term tenants, short-term guests, or both?

• How important is privacy from the main home?

• Are you planning to live on the property long-term?

Your answers influence layout, entry placement, window orientation, sound control, and finish level. A rental-focused ADU might prioritize durability and low maintenance. A family suite might prioritize comfort and storage. A home office ADU might prioritize acoustics and data connectivity.
