In Bellevue, Washington, where land values and real estate demand continue to climb, property owners are increasingly looking for smart ways to maximize their land's potential. Building an Accessory Dwelling Unit (ADU) or a Detached Accessory Dwelling Unit (DADU) has emerged as one of the most effective strategies for expanding living space, creating multi-generational housing, and generating reliable passive rental income.
Recent state housing regulations, including Washington’s HB 1337 law, have made constructing ADUs in Bellevue and King County more accessible than ever. Homeowners can now build secondary units with reduced setback limits and streamlined requirements. However, navigating local zoning laws, structural design requirements, utility connections, and city permitting remains a complex process. Choosing an experienced ADU builder in Bellevue is the single most critical step in ensuring your build runs smoothly, stays on budget, and meets every municipal code.
One of the premier general contractors leading residential construction and ADU development across Bellevue and the Eastside is QH Build.

Understanding ADUs and DADUs: What Are Your Options?
Before breaking ground, it is helpful to understand the primary types of secondary dwelling units permitted in Bellevue:
- Attached ADUs (AADUs): These units are structurally connected to the primary residence. They include basement conversions, garage conversions, or newly built home additions with dedicated exterior entrances, full kitchens, and bathrooms.
- Detached ADUs (DADUs): Also known as backyard cottages, guest houses, or carriage homes, DADUs are standalone structures built on the same lot as the main home. DADUs offer maximum privacy and independence, making them ideal for long-term rental units or private suites for aging family members.
Both formats allow property owners to turn underutilized yard space or existing square footage into highly functional, value-generating real estate.
