An office finish-out is the most predictable of the commercial build-outs, which is good news if you just signed a lease. In DFW, 2026 office finish-outs run roughly $50 to $150 per square foot. An open plan in a second-generation suite sits at the low end; a private-office layout with glass fronts, a conference room, and a real break room in a raw shell runs to the top.
DFW Office Finish-Out Cost (2026)
| Layout | Cost per Sq Ft | What it includes |
|---|---|---|
| Light refresh (second-gen) | $20–$45 | Paint, carpet, lighting, minor moves |
| Open-plan finish-out | $50–$90 | Open floor, a few rooms, break area |
| Standard private-office | $80–$125 | Offices, conference, reception, break room |
| Upgraded / glass-front | $110–$150+ | Glass fronts, premium finishes, AV |
What Drives an Office Build-Out Cost
- —Number of private offices and conference rooms - more walls, more doors, more cost
- —Glass storefront and demountable partitions vs standard drywall
- —HVAC zoning and returns for the new room layout
- —Data, low-voltage, and electrical for every workstation and room
- —A real break room or kitchenette with plumbing
- —ADA restrooms if the existing ones do not meet current code
Open Plan vs Private Offices
The biggest cost lever you control is how many walls you build. An open plan with a handful of enclosed rooms is faster and cheaper, and it keeps the space flexible. A heavily compartmentalized layout with many private offices adds walls, doors, electrical, HVAC returns, and lighting circuits - all of which add up. We help you weigh the layout against the budget early, because the floor plan decision moves the number more than the finish selections do.
Second-Generation Space Saves Time and Money
Most office leases in DFW are second-generation, and that is to your advantage. If the prior tenant's layout is close to what you need, reusing the restrooms, the HVAC distribution, and even some walls can save $20 to $40 per square foot and weeks of schedule. We assess what is reusable before you commit, so you are not paying to demolish and rebuild walls that were already where you wanted them.

TI Allowance and Timeline
Office leases commonly include a tenant improvement allowance of $30 to $90 per square foot in 2026 DFW deals, often more on a longer term. A straightforward office finish-out is typically 6 to 10 weeks of construction once permitted, but the permit timeline varies by jurisdiction. We give you an itemized budget early so you can negotiate the allowance and free rent, then submit complete drawings and work the schedule backward from your move-in date.
What to Confirm Before You Sign an Office Lease

- —Do the restrooms meet current ADA code, or is an upgrade triggered?
- —Is the HVAC sized and zoned for your headcount and room layout?
- —What does the TI allowance cover, and what reimbursement proof is required?
- —Who carries the permit, and does the schedule fit your required move-in date?

Frequently Asked Questions
Common questions about this topic from DFW homeowners and project planners.
How much does an office finish-out cost in DFW?
In 2026, DFW office finish-outs run about $50 to $150 per square foot. A light refresh of a second-generation suite can be $20–$45; an upgraded private-office layout with glass fronts and premium finishes reaches the top of the range.
What makes an office build-out more expensive?
Walls, mostly. More private offices and conference rooms mean more partitions, doors, HVAC returns, lighting circuits, and data drops. Glass fronts, a plumbed break room, and ADA restroom upgrades also push the per-square-foot number up.
Is an open plan cheaper than private offices?
Yes. An open plan with a few enclosed rooms uses fewer walls, doors, and systems, so it is faster and cheaper than a heavily compartmentalized layout. The floor plan decision moves the budget more than the finish selections do.
How long does an office finish-out take in DFW?
A straightforward office finish-out is typically 6 to 10 weeks of construction once permitted, plus design and permitting time that varies by DFW jurisdiction. We work the schedule backward from your move-in date and submit complete drawings to avoid review delays.
