Building Permits: Privately owned housing units authorized by building permits in September were at a seasonally adjusted annual rate of 1,215,000. This is 4.5 percent (±1.6 percent) below the revised August rate of 1,272,000 and is 4.3 percent (±1.7 percent) below the September 2016 rate of 1,270,000. Single-family authorizations in September were at a rate of 819,000; this is 2.4 percent (±1.7 percent) above the revised August figure of 800,000. Authorizations of units in buildings with five units or more were at a rate of 360,000 in September.
Housing Starts: Privately owned housing starts in September were at a seasonally adjusted annual rate of 1,127,000. This is 4.7 percent (±8.1 percent)* below the revised August estimate of 1,183,000 but is 6.1 percent (±8.8 percent)* above the September 2016 rate of 1,062,000. Single-family housing starts in September were at a rate of 829,000; this is 4.6 percent (±8.5 percent)* below the revised August figure of 869,000. The September rate for units in buildings with five units or more was 286,000.
Housing Completions: Privately owned housing completions in September were at a seasonally adjusted annual rate of 1,109,000. This is 1.1 percent (±12.4 percent)* above the revised August estimate of 1,097,000 and is 10.3 percent (±11.9 percent)* above the September 2016 rate of 1,005,000.

In interpreting changes in the statistics in this release, note that month-to-month changes in seasonally adjusted statistics often show movements which may be irregular. It may take three months to establish an underlying trend for building permit authorizations, six months for total starts, and six months for total completions. The statistics in this release are estimated from sample surveys and are subject to sampling variability as well as nonsampling error including bias and variance from response, nonreporting, and undercoverage. Estimated relative standard errors of the most recent data are shown in the tables. Whenever a statement such as "2.5 percent (±3.2 percent) above" appears in the text, this indicates the range (-0.7 to +5.7 percent) in which the actual percentage change is likely to have occurred. All ranges given for percentage changes are 90 percent confidence intervals and account only for sampling variability. If a range does not contain zero, the change is statistically significant. If it does contain zero, the change is not statistically significant; that is, it is uncertain whether there was an increase or decrease. The same policies apply to the confidence intervals for percentage changes shown in the tables. On average, the preliminary seasonally adjusted estimates of total building permits, housing starts and housing completions are revised 3 percent or less. Explanations of confidence intervals and sampling variability can be found at the Census Bureau's website (https://www.census.gov/construction/nrc/how_the_data_are_collected/index.html).
* The 90 percent confidence interval includes zero. In such cases, there is insufficient statistical evidence to conclude that the actual change is different from zero.
