Why Build an ADU? The Benefits Explained
ADUs offer numerous advantages for homeowners, making them a worthwhile investment. Here are some key benefits:
1. Additional Income Potential
Rent out your ADU for long-term tenants or short-term vacation rentals (where permitted).
Generate passive income to help cover your mortgage or retirement expenses.
2. Increased Property Value
Homes with ADUs typically sell for 10-30% more than those without.
Buyers are attracted to the flexibility and extra space ADUs provide.
3. Multi-Generational Living Solutions
Perfect for aging parents, adult children, or live-in caregivers.
Offers privacy while keeping loved ones close.
4. Faster More Affordable Than Moving
Avoid the high costs and stress of buying a new home.
Customize your ADU to fit your exact needs.
5. Eco-Friendly Housing Option
Smaller footprint means lower energy consumption.
Can be built with sustainable materials and solar power.
With these advantages, it’s no wonder ADUs are booming in popularity. But before you start building, you need a trusted team like ADU Builders Group to guide you through the process.
Types of ADUs: Which One Is Right for You?
Not all ADUs are the same—depending on your property and needs, you may choose one of these common styles:
1. Detached ADU (Backyard Cottage)
A standalone unit separate from the main house.
Offers the most privacy and flexibility in design.
2. Attached ADU
Connected to the primary residence (e.g., a garage conversion or side extension).
Often more cost-effective than a detached unit.
3. Garage Conversion ADU
Turns an existing garage into a livable space.
Faster approval process since the structure already exists.
4. Junior ADU (JADU)**
A smaller unit (max 500 sq. ft.) created within the main home.
Ideal for single occupants or minimal space needs.
ADU Builders Group helps you determine the best type for your property, budget, and goals.
