How much does an ADU cost in Washington State?

ADU costs in Washington State typically range from $150,000 to $400,000+ depending on size, site conditions, finish level, and local jurisdiction requirements. NBE LLC provides detailed feasibility studies with exact quotes based on your specific property.

What is HB 1337 and how does it affect ADU construction?

HB 1337 is a Washington State law that allows homeowners in most cities to build at least two ADUs on single-family lots. It relaxed parking requirements, reduced setbacks, and removed owner-occupancy mandates, making ADU construction more accessible across the Puget Sound region.

Do you offer disability home retrofit services?

Yes. NBE LLC specializes in ADA-compliant home modifications including wheelchair accessibility, roll-in showers, grab bars, wider doorways, and aging-in-place renovations. We serve homeowners across King, Pierce, and Snohomish Counties.

How long does a typical renovation take?

Project timelines vary by scope: kitchen remodels typically take 6-10 weeks, bathroom remodels 4-8 weeks, home additions 3-6 months, and custom ADU builds 4-8 months. NBE LLC provides detailed timelines during our feasibility study phase.
