Washington vs Oregon on the underlying numbers
Cost per square foot is a summary. These are the measured inputs behind it, each from a named federal source, so you can see why the two states differ rather than just by how much.
| Measure | Washington | Oregon |
|---|---|---|
Mid-range cost per sq ft Construction only, land excluded | $221 | $210 |
Builder-grade per sq ft Same basis, entry-level finishes | $164 | $155 |
Median trade wage BLS OEWS, May 2025 — the largest single driver of the cost gap | $36.3/hr | $31.79/hr |
Electrician BLS OEWS median | $45.78/hr | $48.71/hr |
Land share of property value FHFA WP 19-01 | 39.7% | 36.1% |
Implied land markup on build Share divided by (100 minus share) | 66% | 56% |
Heating degree days NOAA 10-year average, base 65F | 5,471 | 5,121 |
Cooling degree days Drives HVAC sizing and running cost | 244 | 313 |
Residential energy code U.S. DOE Building Energy Codes Program | 2021 Washington State Energy Code | 2023 Oregon Residential Specialty Code |
Single-family permits, 2025 Census BPS — how deep each builder market is | 17,780 | 9,215 |
Median new home in region Census Survey of Construction | 2,090 sq ft | 2,090 sq ft |
Wages and land account for most of the gap between any two states. Climate and code set the mechanical and envelope spec, and permit volume tells you how much competition there is for a builder's time — which affects the price you are quoted as much as any line item.
