An Accessory Dwelling Unit (ADU) is a secondary residential living space located on the same property as a primary home. Depending on your property and local regulations, an ADU may be built as a detached structure, attached addition, garage conversion, above-garage apartment, basement apartment, or by converting existing interior space into a fully functional living area.
Most ADUs include living space, a sleeping area, a bathroom, and a kitchen or kitchenette, creating an independent space for family members, guests, caregivers, or tenants where permitted.
Because zoning regulations, lot requirements, utilities, and permitting vary by municipality, every ADU project begins with understanding your property’s unique opportunities and limitations.
Every property is different, which means the best ADU solution depends on your lot, existing home, budget, and long-term goals. Absolute Building Concepts constructs a variety of Accessory Dwelling Units (ADUs) designed to fit your lifestyle and maximize the potential of your property.
Detached ADUs are separate structures built on the same property as your primary residence. These private living spaces are ideal for aging parents, adult children, long-term guests, rental opportunities where permitted, or anyone who wants greater privacy while remaining close to family.
An attached ADU expands your existing home while providing its own independent living area. This option offers convenient access between living spaces while maintaining privacy for both households.
Converting or building living space above a garage is one of the most popular ways to create an ADU. Garage apartments make excellent guest accommodations, multigenerational living spaces, home offices, or rental units where local regulations allow.

When your existing home doesn’t have enough usable space, a custom addition may be the best solution. An addition can be designed specifically to create an independent living area while blending seamlessly with the architecture of your home.
