An ADU is attached to or incorporated within the existing home. A (Detached Accessory Dwelling Unit) DADU is built as a separate, detached structure on the same property as the main home.

A home addition expands your existing living space, while an ADU is designed as a separate, self-contained residence with its own kitchen, bathroom, and private living area. Both add value, but an ADU offers greater independence and versatility.

The cost of an ADU depends on its size, layout, structural requirements, utility connections, and finish selections. We'll provide a customized estimate based on your home, lifestyle, and long-term goals.

Most ADU projects take 6 to 12 months from design through construction. The timeline varies depending on permitting, inspections, utility work, customization, material selections, and overall project complexity.

Yes. ADUs typically require building permits and must comply with local zoning regulations, building codes, and utility requirements. We'll help guide you through the permitting process before construction begins.

ADUs are commonly used for aging parents, adult children, guests, caregivers, private home offices, or long-term rental opportunities where permitted by local regulations.

Many homes can accommodate an attached ADU, but feasibility depends on your home's layout, available space, structural considerations, and local regulations. We'll evaluate your property and discuss the best options for your goals.

Absolutely. We carefully design every ADU to complement your home's architecture, exterior materials, and interior finishes, creating a seamless extension that feels intentional and cohesive.

Yes. A true ADU is designed as a fully functional living space with its own kitchen, bathroom, living area, and sleeping space, providing privacy and independence for its occupants.

ADUs offer homeowners greater flexibility by creating additional living space without purchasing a new home. Whether used for family, guests, or future rental opportunities, they provide a practical investment that adapts to changing lifestyles. For example, ADUs are one of the most popular solutions for multigenerational living, offering family members privacy and independence while keeping loved ones close. They're also a flexible investment that can adapt to your family's changing needs over time.
