What Is an ADU (Additional Dwelling Unit)?

An ADU, also known as an accessory or additional dwelling unit, is a secondary living space located on the same property as a primary residence. ADUs provide flexible housing solutions for multigenerational living, rental income, guest accommodations, or long-term investment value. Stella Home Services works closely with homeowners to design ADUs that meet local zoning requirements, blend seamlessly with the existing home, and function as independent living spaces.

Our ADU Construction Services

Basement ADU & Basement Finishing

Turn your basement into a comfortable, code-compliant living space with proper egress, insulation, soundproofing, and modern finishes. Ideal for rental units, guest suites, or in-law apartments.

In-Law Suite Additions

Create a private, accessible living space for family members while maintaining connection to the main home. In-law suites can be built as additions or integrated within existing layouts.

Garage Conversion ADUs

Convert an existing garage into a fully functional dwelling unit with a kitchen, bathroom, and living area. Garage ADUs are a cost-effective way to add living space without expanding the home’s footprint.

Add a new structure or wing designed specifically as an ADU. These additions are custom-designed to match the architecture of your home while maximizing livability and privacy.
