Ballpark the building
Our builds usually run $325 to $550 per square foot, depending on finishes. That covers the building. Site work, utility connections and septic depend on your lot, so we price them after a site visit.
Building estimate range
—
An estimate range, not a bid. Permit fees shown are Kitsap County's published approximations for unincorporated Kitsap; city fees differ. Your fixed price comes from a site visit and a line-item estimate.

Questions
Package FAQ
Do I have to buy the build package?
No. Many owners start with the permit-ready package and decide on construction once the permit is in hand.
What does the build cost?
Our ADU builds usually run $325 to $550 per square foot for the building, depending on finishes. Site work, utility connections and septic depend on your lot and are priced separately after a site visit.
How is the build price set?
After a site visit we prepare a line-item estimate and a fixed-price contract, so the number doesn't move unless the scope does.
What isn't included?
Site work, utilities and septic, plus permit, impact and connection fees paid to the jurisdiction and utilities. We list them in your quote so nothing is a surprise.
