TAM $95B, SAM $15.4B, SOM $881M a year: the West Coast demand audit, November 2026.
Every apartment and townhome permitted in California, Oregon and Washington, counted from Census files. Dollars use the Portland prototype home, 694 square feet, so they run low.

Apartment permits swing with the cycle, and 2025 was near the bottom.
Homes in buildings of two or more units, three states.[4] January to September 2026 ran 26% ahead of 2025.
