Housing Statistics

1. Number of houses built per year - about 1.5M in the USA - [1]
2. Number of tiny houses built per year - about 1.5K [2]
3. Spec vs owner-builder housing - 50k owner built homes in 2014 [3]. This is a small fraction of total supply. But, this does not include rural areas (no permits) - which may bring the number up to be much higher.
