Tenant Improvement Contractor in Metro Atlanta

The problem

You have a lease signed and a build-out allowance to spend, and the clock started the day you took the keys. You need a contractor who can price the work against the landlord’s scope, pull the permit, and turn the space over before rent commencement catches up with you.

What's included

Real scope, trade by trade

  • Demo and selective interior demolition

  • Ceilings — ACT and hard-lid
  • Storefront and interior glazing
  • Electrical, lighting, and low-voltage rough-in and trim
  • HVAC modification and distribution
  • Plumbing rough-in and fixtures
  • Flooring — LVT, tile, carpet, sealed concrete
  • Paint and interior finishes
  • ADA restrooms and code upgrades
Scope vs. swingers

What a TI includes vs. what swings the budget

A tenant improvement is the interior work that makes a leased space work for your use. Demo, framing, drywall, ceilings, lighting, flooring, and paint are the usual package. The budget swingers are the systems — HVAC, the electrical panel, restrooms, and a change of occupancy — not the finishes.

Usually in the package

  • Demo and selective demolition. What has to come out before the new layout goes in.
  • Framing, drywall, ceilings. Metal stud partitions, ACT or hard-lid, storefront and interior glass.
  • Lighting and branch electrical. Rough-in, fixtures, and trim — assuming the panel can carry it.
  • Flooring and paint. LVT, tile, carpet, sealed concrete, and interior finishes.
  • HVAC distribution. Duct and diffusers inside the suite, when the unit already has capacity.
  • Restroom finishes. Fixtures and ADA upgrades in restrooms that stay where they are.

What actually swings the number

  • HVAC capacity or replacement. Tonnage, a rooftop unit that is not actually delivered, or distribution that cannot serve the new layout.
  • Electrical panel and service size. Amps at the panel vs. amps your use needs. A service upgrade is a different job than swapping fixtures.
  • Moving restrooms. Bathrooms tie to gravity waste lines in the slab. Relocating one is a plumbing project with a finish attached, not a layout preference.
  • Change of occupancy. Retail to restaurant, office to clinic, storage to assembly. That is a different review — exiting, restrooms, ventilation, accessibility — not a finish upgrade.

How it works

Same three steps on every job. What changes is the scope, not the process.

1

Walk the space

We come out and look at what’s actually there — existing conditions, the capacity of the HVAC, electrical, and plumbing, and what your use will trigger for code and accessibility. Bring whatever you have: drawings, the lease exhibit, your target date. It takes about an hour, and we get on the calendar within days.

2

Get a real number

We scope it trade by trade — not a per-foot guess — and account for permitting and the long-lead items that actually move a schedule. You get a scoped estimate with the inclusions and exclusions spelled out, so you can hand it to your owner or lender and defend it. Not a range, and usually back in days.

3

We build

We pull the permits, order the long-lead items, and mobilize — self-performing the interior trades and managing the rest, in sequence. You get a point of contact and updates at the milestones that matter, through punch and closeout, including the documents you need to occupy.

Bands we actually use

Cost and timeline

A per-foot average is a sanity check, not a budget. Typical tenant improvements we run land in the $50K–$300K band, over 4–12 weeks of construction. Company-wide, interiors sit in a $50K–$500K sweet spot — most TIs are in the lower part of that range. The number that matters is built from your space.

Common questions

How much does a tenant improvement cost?
It depends heavily on use, existing conditions, and finishes. Most tenant improvements we do land in the $50K–$300K range. Company-wide, interiors sit in a $50K–$500K sweet spot — most TIs are in the lower part of that band. The only number worth budgeting against is a scoped estimate built from your space. A site walk gets you one. Why we don’t quote a $/SF average.
How long does a tenant improvement take?
Typically four to twelve weeks of construction depending on scope, but permitting and long-lead items often drive the calendar more than the build itself. We give you a realistic schedule with the estimate. What actually moves a commercial buildout date.
Do you handle permitting across City of Atlanta, DeKalb, Gwinnett, and Cobb?
Yes. We pull the building and trade permits and coordinate with the jurisdiction. If the address sits inside a city, that city usually permits the job — not the county. City of Atlanta is its own AHJ, not Fulton County. DeKalb, Gwinnett, and Cobb each run a county process in unincorporated areas; cities inside those counties permit their own. Confirm the AHJ by address, not mailing city. Permitting a commercial buildout in Metro Atlanta · Atlanta location.
Can you work around the landlord’s work letter?
Yes — and we read it against the space before we price, so the split between landlord and tenant scope is clear and the gaps get caught before they become change orders. Who pays for what in a tenant improvement.
Does the landlord’s TI allowance cover the actual cost?
Usually not, or not all of it. The allowance is a dollar contribution negotiated in the lease — not a scope. Everything past it is yours, and anything the work letter left unclaimed becomes a tenant cost after you sign. Read what it covers, when it is paid (up front vs. reimbursed after CO), and have a contractor walk the space against that letter before you treat the allowance as the budget. How a work letter actually splits cost.
What’s the difference between second-generation space and a shell?
Second-generation space was already built out, usually for a similar use. You may inherit restrooms, HVAC, electrical distribution, and a ceiling grid — which cuts a meaningful share of scope before design starts. A cold dark shell is slab, exterior walls, and utility stubs. Same floor area, very different job. Two identical plans in the same building can land far apart on cost because of this column alone. What existing conditions do to a TI number.
Should I walk the space before I sign the lease?
Yes. A contractor reading the work letter against the actual panel, HVAC unit, and drain locations will find the items neither party claimed — while they are still negotiable. After signature, those same items are tenant cost. Bring drawings, the lease exhibit, and your target date. It takes about an hour. Atlanta office and how to reach us.
