MIAMI—It's getting tougher and tougher to find quality class A office space in the Miami area, with ever-increasing demand for prime locations. Office experts Jonathan Kingsley and Stephen Rutchik of Colliers International South Florida are right in the middle of the fray.

The dynamic office leasing duo is in charge of leasing at Harbour Centre, an office building in the northeast Miami submarket of Aventura that recently reached the 97% mark in occupancy. On their watch, Harbour Centre has become a popular location that commands strong rental rates.

Noteworthy is the fact that Kingsley and Rutchik have kept the leasing assignment over nine years, even while changing their brokerage affiliation. GlobeSt.com caught up with Kingsley to discuss the state of Miami's office market and where we go from here.

GlobeSt.com: You say the Miami office market is tighter than ever for class A space. What does that mean to those looking for space in the market?

Kingsley: It's a landlord's market right now. We are seeing a reduction in tenant improvement deals and concessions, with the exception of some high-creditworthy tenants in long-term leases. Meanwhile, lease rates are continuing to increase, reflecting the fact that new tenants keep coming into the Miami market, with next to no new developments planned or under construction.

GlobeSt.com: Where is the Miami office market going from here?

Kingsley: The market will keep getting tighter, because building new office space from the ground up isn't practical in this submarket at this point. The challenges include finding land that is priced right, dealing with increased costs of construction and working with today's financing market. To get financing, an owner would need to have an anchor tenant that will fill at least 50% of the building, and this is difficult to accomplish.

Certainly, over time, growth will lead to more development at the edges of the city's core. But as that occurs, it will be more and more important for the area to develop good options for transportation. There are some promising beginnings here in that regard, such as the All Aboard Florida rail system that's on the way, but more needs to happen to help workers get to and from work.
