One of the first questions every homeowner asks is: what’s this going to cost? The honest answer is that ADU pricing in Vancouver, WA isn’t one-size-fits-all — and anyone who gives you a flat rate without understanding your project is guessing. Here’s a straightforward breakdown of what drives cost so you can plan with confidence.
The size and type of ADU you build is the biggest cost driver. A small space ADU or garage conversion costs significantly less than a fully detached ADU built from the ground up. Attached ADUs and basement conversions fall somewhere in between. Larger scope means more cost — but also more value and income potential added to your property.
The category of ADU directly affects budget. A detached ADU on your property involves its own foundation, framing, roofline, and full utility connections. An attached ADU shares a wall with your existing home, reducing some structural costs. A garage or basement conversion works with an existing structure, which can lower costs but still requires plumbing, electrical, and insulation work. We’ll walk you through realistic numbers for your specific project from the very first conversation.
The materials you choose — from siding and roofing to flooring and fixtures — have a direct impact on cost. We offer options at multiple price points without compromising structural quality. Whether you want budget-friendly finishes or premium custom materials, we’ll match the ADU to your existing property and your investment goals.
All ADUs require permits, We handle the full permitting process, but these fees are part of your project budget. Site conditions — soil, slope, utility access, and existing structures — can also affect cost. We identify these factors during the planning phase so there are no surprises mid-project.
The only way to give you a number we’ll actually stand behind is to understand your specific property and project. We offer free consultations and detailed written estimates with no hidden fees. No guesswork, no lowball bids followed by change orders. Contact us today to get started.
