Overall supply of office space in the Boise area is within a healthy range (13.4 months), despite the lowest vacancy rates since 2002 (7.23%). To put it simply, tenants are able to find space within a reasonable time regardless of the tight market.
While the supply is projected to continue its decline, there has been an increase in demand for spaces over 10,000 square feet. Transactions over 10,000 square feet had a 40% increase from 2017 to 2018, and the demand for these spaces is increasing.
Interestingly, while these trends are occuring, the overall environment of office space is evolving according to an article by the Idaho Statesman. Employers are trying to fit more people per square foot by tearing down walls and creating more free flowing spaces. As the popularity for spaces like this continues to grow, it could act as a counterweight to the demand for larger spaces, as many employers will be able to fit more people in a smaller amount of space.
