Summary
The 2026 Buildability™ Permit Friction Index ranks the 10 hardest U.S. cities to get a building permit in as of Q2 2026. San Francisco, CA leads with a median building-permit time of 392 days, followed by Honolulu, HI (318), Berkeley, CA (296), Cambridge, MA (282), Boston, MA (275), Los Angeles, CA (268), New York, NY (247), Seattle, WA (231), Portland, OR (224), and Chicago, IL (212). All ten F-grade cities share three traits: paper or hybrid intake on at least one major review path, sequential review across building/zoning/engineering/fire, and a base zoning code older than 30 years. The index is the inverse weighting of the friendly-cities ranking and uses the same five factors: median days to permit (40%), process modernization (20%), impact fee trend (15%), code modernization (15%), and environmental review friction (10%). Sample size: 9,604 single-family residential permits. Three F-grade cities cut median days by 20+ quarter-over-quarter (Los Angeles, Seattle, Chicago). Updated quarterly. Next release: July 2026.
