What Is an Accessory Dwelling Unit (ADU)?

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.

  • Homeowners choose ADUs for many reasons, including:
  • Housing aging parents while maintaining independence
  • Creating space for adult children or multigenerational living
  • Accommodating long-term guests or caregivers
  • Generating rental income where local ordinances allow
  • Adding flexible living or work-from-home space
  • Increasing the long-term value and functionality of their property

Because zoning regulations, lot requirements, utilities, and permitting vary by municipality, every ADU project begins with understanding your property’s unique opportunities and limitations.

Types of ADUs We Build

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

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.

Attached ADUs

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.

Garage Apartments

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.

Basement Conversions

An unfinished or underutilized basement can often be transformed into a comfortable and functional living space. Basement ADUs make excellent in-law suites, guest quarters, entertainment spaces, or independent living areas while making better use of your home’s existing footprint.

Home Additions

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.

Interior Space Conversions

Many homes have unused or underutilized areas that can be converted into functional living spaces. Depending on your home’s layout and
