ADUs, or Accessory Dwelling Units, are quickly becoming one of the most talked-about housing solutions in Florida—and for good reason.
An ADU is a smaller, secondary home located on the same property as a primary residence. You may also hear them referred to as:
Granny flats
Backyard dwellings
In-law suites
Guest houses
With recent changes across Florida, more homeowners are now able to add an ADU to their property without the hurdles that once made it difficult. That means more opportunity to maximize your property, create additional living space, or generate rental income.
Why ADUs Are in High Demand Right Now
This isn’t just a trend—it’s a shift in how people are thinking about housing.
✔️ Generate Additional Income
ADUs are increasingly being used as long-term or short-term rental units, creating a new income stream right from your backyard.
✔️ Multigenerational Living
Keep family close while maintaining privacy. ADUs are ideal for aging parents, adult children, or extended family.
✔️ Increase Property Value
A well-designed ADU can significantly improve your property’s value and long-term appeal.
✔️ Flexible Living Options
From home offices to guest spaces, ADUs give you flexibility now—and options for the future.
Why Modular Homes Are Leading the ADU Movement
Not all ADUs are created equal—and this is where modular construction stands out.
At Movable Roots, our ADUs are built as modular homes on a permanent foundation, meaning they are:
Built to Florida Building Code
Engineered for Florida wind ratings
Designed for long-term durability
Eligible for traditional financing (when applicable)
Unlike structures built on wheels or temporary foundations, modular ADUs are true homes, built for real, everyday living.
What Is a Modular Home?
A modular home is built in a controlled environment (like our Melbourne warehouse) and then transported to your property and set on a permanent foundation.
This approach allows for:
Consistent, high-quality construction
Protection from weather during the build process
Greater efficiency without sacrificing craftsmanship
The end result? A home that meets the same codes and standards as a site-built home—just built differently.
ADU vs. Tiny Home vs. Park Model: What’s the Difference?
This is one of the most common questions we get.
Modular ADU → Built to state and local building codes, placed on a permanent foundation
Tiny Home on Wheels (THOW) → Built to RV standards, not typically allowed as a full-time residence
Park Model RV → Recreational unit, usually limited to RV parks or specific communities
If your goal is a legal, long-term backyard dwelling or income-producing property, a modular ADU is typically the best fit.
