Key Takeaways
- Washington construction costs run $188-$375/SF residential, $250-$500/SF commercial, and $188-$313/SF industrial.
- Local factors — not a single Washington price — drive where a project lands in these ranges.
- Use the national ranges as a baseline, then adjust for Washington's labor, permits, and site conditions.
- Always get local contractor quotes — these are planning ranges, not bids.

What drives Washington construction costs
There is no single "Washington price per square foot." Your project lands higher or lower in the range based on:
- Federal prevailing wages (Davis-Bacon) lift many commercial bids.
- Historic preservation and CFA review constrain design and material choices.
- Security and blast requirements add cost to federal and embassy-adjacent work.
