ADU Types Available in Rowe
Rowe allows 3 type(s) of ADU. Each has different cost, timeline, and design implications.
- Detached ADU — a standalone building in your yard with its own entrance, utilities, and foundation. Best for privacy and rental income.
- Attached ADU — an addition connected to your main home that shares at least one wall. Lower construction costs than detached.
- Conversion ADU — transforms existing space like a basement, attic, or garage into a separate dwelling. Fastest and cheapest to build.
Which ADU Type Is Right for You?
The best ADU type for your property in Rowe depends on your lot size, budget, and goals. If you want maximum rental income and privacy, a detached ADU is ideal.
