2013 was a big year for Bismarck-Mandan.
The Home Builders Association says their combined value went up more than 200 million dollars.
They've seen an increase in permit numbers for single family homes, multi-family homes, additions and remodels.
The association also added 33 new builder members and 31 affiliate members, a 6.6 percent increase from 2012.
"I think the economy in Bismarck is driving these numbers and we see a lot of demand going forward as well," says Eric Brenden, Past President of the HBA.
Additions and remodels alone added 7.1 million dollars to Bismarck-Mandan's home values.
This includes the addition of garages, patios, fireplaces and finished basements.
"I think Bismarck is a gem for western North Dakota. The economy is very strong, and we have 2.3 percent unemployment which is unheard of," Nathan Jones Chief Operating Officer of Tollberg Homes said.
Lincoln's value also went up 12.7 million dollars.
