One of the first questions we hear is, how much does it cost to build an ADU? The truth is, costs can vary widely based on the type of ADU, site conditions, and finish level. Detached units tend to cost more than garage conversions, while single-story builds may offer cost savings over two-story options.

On average, homeowners in Olympia spend between $150,000 to $300,000+ depending on square footage, access, and finish level. We break down costs upfront, so you always know what you’re getting into—no surprises.

We also walk you through the permitting and inspection process so you understand what your fees are paying for. Whether you need a detailed budget breakdown or want to explore ways to build in phases, we’re here to help.
