The Tri-Cities boasted a record-setting year in the residential housing market for the fourth year in a row.

The region recorded a four percent year-over-year increase in the number of single-family residential permits filed in 2017, with 1,446 tallied in Benton and Franklin counties.

The value of all those permits? More than $421 million. That’s more than five percent higher than the previous year’s value of more than $399 million.

West Richland recorded the highest percentage of year-over-year growth at 29 percent with 103 home building permits filed in 2017, compared to 80 the previous year.

Pasco came in next with 21 percent year-over-year growth with 469 permits, compared to 387 filed in 2016.

Richland showed an eight percent uptick in the number of single-family housing permits issued last year — 295 compared to 273 the previous year.

The number of single-family home permits recorded in Kennewick dropped about 34 percent over the previous year with 211 compared to 319 in 2016.

The two counties issued 67 manufactured home permits in 2017, a drop of 50 percent compared to the previous year.

Jeff Losey, the executive director of the Tri-Cities Home Builders Association, recently told the Tri-Cities Area Journal of Business that the region has an opportunity to exceed 2017’s numbers as more lots for houses are expected to become available this year.
