Building accessory dwelling units on private property is one of the fastest-growing trends in Washington State’s real estate market. In Bellevue, WA—where land and home values continue to rise rapidly—homeowners are increasingly turning to ADUs (Accessory Dwelling Units) and DADUs (Detached Accessory Dwelling Units). These structures offer more than just extra living space for families; they serve as a highly effective tool for generating stable passive rental income.
However, constructing a secondary living unit requires a deep understanding of local building codes, zoning regulations, and construction standards. Selecting a dependable general contractor is the most critical decision in ensuring a project’s success. One of the leading companies specializing in ADU and DADU construction across Bellevue and the Eastside is QH Build.
What are ADUs and DADUs? Understanding the Difference
Before diving into design and planning, it is essential to understand the basic terminology:
- ADU (Accessory Dwelling Unit): An attached or integrated secondary housing unit. Examples include garage conversions, finished basements, or built-on additions featuring a separate entrance, kitchen, and bathroom.
- DADU (Detached Accessory Dwelling Unit): A standalone residential structure on the same lot as the main home. These are often referred to as backyard cottages, guest houses, or detached secondary units.
While both options provide privacy and independence, a DADU offers maximum separation between the primary residence and the secondary dwelling.
