Counties with the most building permits
How this is measured. Units authorized in permit-issuing jurisdictions within the county, summed over the trailing 12 months. Multifamily share is the portion of those units in buildings with 5 or more units. Permits per 1,000 residents is shown for counties with at least 25,000 residents, using the population published with HUD's FY2026 Fair Market Rents, which carries a 2023 base year — roughly three years older than the permit window.
Figures are new privately owned residential units authorized by building permits, from the U.S. Census Bureau Building Permits Survey. A permit authorizes construction; it is not a housing start and not a completion. Permits lead starts by weeks to months, and some authorized units are never built. The survey covers permit-issuing jurisdictions: a jurisdiction that did not report in a month contributes nothing for that month, so an absent figure is not a zero. Data window ends Jun 2026.
Every U.S. county ranked by residential units authorized in the 12 months to Jun 2026. Maricopa County, Arizona leads at 28,806 units.
A permit is an authorization, not a housing start — some authorized units are never built.

Counties with the most building permits — FAQ
Which county issues the most building permits?+
Maricopa County, Arizona authorized 28,806 housing units in the 12 months to Jun 2026, the most of any U.S. county (Census Building Permits Survey).
Are unincorporated areas included?+
Yes, where the county itself issues permits. County totals are the sum of every reporting permit-issuing jurisdiction assigned to that county, which includes county-run permit offices.
Why is a county I expected missing?+
A county whose jurisdictions did not report for a month contributes nothing for that month — absent is not the same as zero. Counties with no reported units in the window are omitted.
