ACCESSORY DWELLING UNITS / JACKSONVILLE FL
BUILD YOUR
ADU.
Add living space. Generate rental income. Increase your property value by up to 30%. We design and build custom accessory dwelling units that pay for themselves.
WHAT IS AN ADU?
An Accessory Dwelling Unit is a secondary living space on your existing property. Whether it is a converted garage, a detached backyard cottage, or a basement transformation, an ADU gives you a fully functional home within your home.
Jacksonville homeowners are building ADUs for rental income, multigenerational living, home offices, and guest suites. With rising housing costs and changing zoning laws, ADUs are one of the smartest investments you can make in your property.
TB Construction handles every phase. Permits, design, foundation, framing, plumbing, electrical, finishes. One contractor. One point of contact. No subcontractor runaround.
