- What does a building permit count mean?
- The Census Bureau counts new privately owned housing units authorized by building permits. A permit is not a finished home: some projects start months later and a few never start. Remodels and nonresidential buildings are not included.
- Why are some counties missing?
- Places without a local permit office are not covered, and some areas report only once a year. Census fills in estimates for permit offices that did not report in a given month.
