- Austin permits approximately 18 new homes per 1,000 residents annually, a rate eight times higher than San Francisco’s 2 per 1,000, due to fewer regulatory barriers.
- San Francisco rent rose nearly 19 percent in the past year despite minimal supply increases, undermining models that predict price declines from small supply expansions.
- Vienna builds housing at a rate similar to London, yet rents are about a third of London’s and have remained flat for two decades.
- Vienna’s housing system includes 43 percent public or nonprofit housing, creating a parallel market that stabilizes prices independently of private-sector permitting reforms.
- London has not developed a parallel public housing system and continues to rely on a heavily regulated private development pipeline with accumulating delays.
- Auckland, New Zealand’s policy change data was used to model U.S. housing elasticity, showing that small supply increases can lower prices—but only up to market saturation limits.
Why it matters: Cities betting solely on deregulation to fix housing affordability may overlook more direct levers like public housing expansion. Vienna’s model shows that parallel systems can stabilize rents even without fast permitting, shifting the debate from process speed to structural design—where the real bottleneck may not be delay, but policy imagination.
