How much does a home addition cost in the Portland area?

Home additions we build across the Portland metro typically start around $125,000 (as of Oct 2026). Where yours lands depends on what you're building:

Size and finish level: more room and higher-end finishes cost more.

Foundation work or a second story: more structure, more cost.

Permits: we handle them, and the fees are part of the total.

Most home additions take 3 to 6 months from permitting through completion. You get a detailed estimate after a free in-home consultation.

What Homeowners Say About Eight Inch Nails

When we finally decided to pull the trigger on a major master bath renovation we knew where to turn. Josh and his team did a wonderful job. His designer did a great job helping us with layout and finishes and everything turned out just the way we envisioned. He's a great communicator, always responding to messages. Our project turned out great!

Master Bath Renovation
8 Inch Nails created my dream kitchen. What was an outdated, broken and non-functional space is now a modern, updated, and functional place I love cooking in. They also transformed a basement storage space into a beautiful bathroom. Their exceptional craftsmanship will stay in my 1930s house forever!
