As Triangle companies bring teams back together, the office fit-out is having a moment — and the bar has risen. A "tenant improvement" today often means a Class-A environment built to attract talent, not just enclose desks. In the Raleigh market in 2026, office build-outs run $50 to $200 per square foot, and the difference between those ends is mostly finish level, systems, and how much of the base building you're changing.

Understand your TI allowance

If you're leasing, the tenant improvement allowance is the most important number in your build. It typically covers base building work — partitions, ceilings, flooring, lighting, HVAC distribution, standard finishes — and typically excludes furniture, IT and AV cabling, security, signage, and premium upgrades. The gap between the allowance and the office you actually want is your out-of-pocket cost, so model it early. For how this factors into lease-vs-build decisions, see our build-out vs. ground-up guide.

The allowance defines the floor. The office you actually want defines the ceiling. The space between them is your budget — know it before you sign the lease.

What drives cost

  • Density of walls and rooms: more partitions, doors, and conference rooms mean more framing, electrical, and HVAC.
  • Glass fronts and custom millwork: the hallmark of Class-A space, and a clear premium over drywall.
  • Mechanical and electrical: reconfiguring HVAC zoning, adding power and data density, and upgrading for higher occupancy.
  • AV, IT, and security: often outside the TI allowance, and easy to underestimate.

Timeline & delivering on schedule

Most office build-outs run 8 to 16 weeks of construction plus 4 to 8 weeks of design and permitting. The schedule drivers are long-lead items — specialty glazing, custom millwork, certain mechanical equipment — which is exactly why they're identified and ordered during pre-construction, not after framing. When a lease commencement date is fixed, that backward-planned schedule is what gets your team into the space on time. See our commercial practice for the full picture.
