Accessory Dwelling Units by Thomas Custom Builders of VA

Take your ADU to the next level with Universal Design: features like wider doorways and hallways, abundant lighting, and accessible, curb-less showers make these spaces ideal for older adults and those seeking lifelong comfort. Modern aesthetics blend seamlessly with practical additions—think built-in shower seats, stylish grab bars, and sleek tilework—so your space feels both beautiful and accessible.


Your ADU is a “home within a home,” offering immediate benefits to your family and long-term value for resale. As trends shift toward flexible, multigenerational living, properties with ADUs stand out in the Virginia real estate market.


Discover the Possibilities of an ADU

Imagine providing a fully independent living space for your loved ones—right on your own property. In Virginia, an “accessory dwelling unit” or ADU is define as an independent dwelling unit on a residential dwelling lot with its own living, bathroom and kitchen space. Whether you’re considering alternatives to traditional in-law suites or seeking flexible solutions for multigenerational living, an ADU offers privacy, comfort, and versatility for your family.


Why Choose an ADU?


Multigenerational Living: ADUs are perfect for aging parents, adult children, or relatives who need a private yet connected home. Everyone enjoys their own space, while staying close together.

Rental Income: Where permitted, ADUs can be leased to tenants or used as short-term rentals, providing a valuable source of extra income, an especially attractive option in areas with high housing demand.

Increased Property Value: By adding an ADU, you make your property more appealing to future buyers, particularly those seeking flexible accommodation options.

Flexible Functionality: Beyond housing family or tenants, ADUs can serve as private home offices, guest quarters, or creative studios, tailored to your lifestyle needs.

Navigating Virginia’s ADU Regulations

Building an ADU in Virginia involves careful planning to meet local requirements. Here’s what you need to know:

  • Zoning Requirements: Not every property is eligible for an ADU. Confirm with your local zoning office to ensure your lot qualifies.
  • Size Restrictions: ADUs are often limited to a certain percentage of the primary home’s size, or capped at a specific square footage set by your locality.
  • Occupancy Rules: Some areas require the property owner to reside in either the main house or the ADU and may limit the number of occupants.
  • Permitting Process: Securing the right permits is essential. This includes submitting plans for review and undergoing inspections throughout construction.
  • Utility Connections: Depending on local codes, your ADU may need separate or shared utility connections with the main home.


With Thomas Custom Builders, you’ll have expert guidance through every step—from initial consultation and design to permitting and construction—ensuring your project is fully compliant and worry-free.
