New Day Construction works with Bellevue homeowners planning accessory dwelling units, including attached ADUs, detached ADUs (DADUs), garage conversions, and backyard cottages. If you are comparing ADU builders in Bellevue, our team can help evaluate the site, intended use, design requirements, and construction scope.
Accessory dwelling units (ADUs) can provide additional living space on an existing residential property. New Day Construction serves Bellevue and nearby King County communities with ADU planning and construction.
What Is an ADU or DADU?
There are two unit forms: a detached one (DADU) is like a backyard cottage or an attached one (ADU), sharing a wall with the main house. For Bellevue homeowners key purposes are additional living space, rental purposes, or housing for aging family members. ADU/DADU gives property owners flexibility in living arrangements without the need for a larger property.
Types of ADUs We Build in Bellevue
New Day Construction builds ADUs and DADUs in various formats, with the approach depending on lot size and budget:
- Detached ADUs (DADUs): backyard cottages and standalone units
- Attached ADUs: home additions that expand existing living spaces
- Garage conversions: turning underused garages into livable units
- Basement ADUs: private units with a separate entrance, etc.
Bellevue ADU Rules and the Permit Process
In Bellevue, ADU rules impose various size, zone, and setback limits. New Day Construction manages the permitting process from start to finish, including design and final inspection:
- Size limits (up to 1,000 sq ft or 60% of the main house)
- Zone and setback requirements (vary by lot)
- Parking requirements (vary by ADU type)
- Owner-occupancy rules (for some ADU types)
Cost of ADU Construction in Bellevue
What drives ADU costs? There are several factors, such as type of ADU, size/layout, materials/finishes, and site prep for challenging lots. Detached ADUs typically have higher construction costs than garage or basement conversions, but both types will increase the value of your home over time.
