What does an addition actually cost?
A real addition is a serious project: most of ours land between $150,000 and $250,000 depending on size and finishes. If someone quotes you a fraction of that, look hard at what's missing.
Our quote itemizes everything — you'll know exactly where every dollar goes.
If you're not happy with the work, we make it right. Period.
On top of the 18-month workmanship warranty — on a project this size, that matters.

Why OCD Building & Remodeling
- One builder, start to finish. An addition touches every trade there is. You get one contract and one responsible party — Alex — not a general contractor who disappears behind his subs.
- The owner quotes it, the owner runs it. No estimator handoff, nothing lost in translation between the person who priced it and the person building it.
- Detail-obsessed. The company is called OCD for a reason. Additions live or die on how the new construction meets the old — that seam is where we're pickiest.
- Straight answers. Real price ranges up front, an itemized quote, no pressure.
