What to expect during a commercial tenant improvement in DFW: permits, schedule and budget

A tenant improvement is the work that turns leased space into space your business can actually use: demising walls, offices and conference rooms, ceilings, lighting, power and data, HVAC distribution, restrooms, flooring and finishes. If you have never run one, the hardest part is not the construction. It is knowing what happens in what order, and what the landlord, the city and your own schedule each need from you.

Here is how a typical Dallas–Fort Worth tenant improvement runs.

Start with the lease and the landlord

Before anything is drawn, read the work letter in your lease. It defines what the landlord is delivering (shell condition, existing HVAC tonnage, restrooms, sprinkler coverage), what allowance you get, and what approvals you need before a contractor sets foot on the floor. Most landlords require the plans, the contractor's insurance certificates and a construction schedule before they issue a notice to proceed. Buildings with an active tenant base usually add rules about work hours, elevator use, dust control and after-hours noise.

Getting this in hand first prevents the most common budget surprise: discovering the base building does not support your layout, and paying for HVAC or electrical upgrades nobody planned for.

Design and scope

A licensed architect prepares the construction documents; in most commercial work an MEP engineer stamps the mechanical, electrical and plumbing drawings. Even on a simple office layout, spend the time on the parts you cannot change cheaply later: where the walls go, how many circuits the space needs, where data drops land, and whether your occupancy type or occupant load changes anything about egress and restrooms.

Ask your contractor to price the drawings as they are, then price the alternates separately — an upgraded ceiling tile, glass fronts instead of drywall, sealed concrete instead of carpet. That way you are comparing one scope, not guessing why two bids differ.

The permit path

Commercial build-outs are reviewed and permitted by the city the building sits in, and every DFW city runs its own portal and its own review queue. Dallas, Fort Worth, Irving, Plano, Richardson, Arlington, Frisco and Garland each have their own submittal requirements, and several also require contractors to be registered with the city before a permit will be issued. Plan review on a straightforward office build-out is usually measured in weeks, not days, and comments from the reviewer mean a resubmittal.

Two practical points. First, the permit clock starts when a complete package is submitted, so an incomplete submittal costs you more than it saves. Second, if the space is in a building with a fire sprinkler or fire alarm system, those trades often permit separately, and their inspections are frequently what holds up your certificate of occupancy.

A realistic schedule

For a standard office or retail build-out, a reasonable planning schedule looks like this:

• Design and engineering: 3 to 6 weeks
• Landlord review and bidding: 2 to 4 weeks
• City plan review and permit: 3 to 8 weeks depending on the city and the complexity
• Construction: 6 to 14 weeks depending on square footage and scope
• Inspections, punch and certificate of occupancy: 1 to 3 weeks

Long-lead items deserve their own line. Rooftop HVAC units, electrical switchgear, specialty glass and some door hardware can take longer to arrive than the framing and drywall take to install. Order those the day the permit is submitted, not the day the walls go up.

How the budget is structured

A commercial bid should be itemized. You want to see labor and material broken out by trade with quantities behind them, general conditions listed separately, and the contractor's fee stated clearly. On larger jobs that becomes a schedule of values, which is also what the monthly pay applications are measured against.

Set aside a contingency for the things nobody can see before demolition: what is actually inside the existing walls, whether the slab is level, whether the existing panel has the capacity the drawings assume. In older buildings, plan for more of that, not less.

Changes are normal. What matters is that every change is written, priced and signed before the work happens, so the final invoice never contains a surprise.

What causes delays

In our experience, delays cluster in a few places: incomplete permit submittals, landlord approvals nobody chased, long-lead equipment ordered late, and scope decisions left open while the crew waits. Finish selections are a quiet one — a flooring choice made in week two costs nothing, and the same choice made in week nine can stall the job.

What we do

We walk the space with you, coordinate with your architect and engineer, and return an itemized bid with a schedule. We pull the permit, run the trades, meet the inspectors, and keep you current through a private project portal so you can see photos, schedule and open items without waiting for a phone call. Our electrical and plumbing work is performed by licensed tradesmen on our team.

If you are planning a build-out in Dallas–Fort Worth, we can walk the space within 24 to 48 hours and put an itemized number in front of you after the walk.
