You’ve signed, or you’re about to sign, a lease on a commercial space in Dallas-Fort Worth. Somebody on the landlord’s side called the work a “renovation.” Your architect called it a “build-out.” Which is it? Fair question.
The two words describe different jobs with different cost profiles, permit paths, and schedules. Getting the label right early saves you weeks. Getting it wrong buys you a redesign at the worst possible moment.
Renovation and build-out aren’t the same job
A commercial renovation updates a space that’s already finished and functioning. Walls, ceilings, restrooms, HVAC, and electrical service already exist. You’re changing finishes, moving a few walls, upgrading lighting, maybe reworking a reception area. The building already knows how to be a building.
A commercial build-out (you’ll also hear “finish-out” or “tenant improvement”) starts from a shell. First-generation shell space typically has a slab, exterior walls, a roof, and utility stubs somewhere near the demising wall. No ceiling grid. No restrooms. No distribution ductwork. Everything a person will touch, you’re adding.
The City of Dallas puts both under one umbrella. Its Development Services department defines a commercial building permit as an official authorization required before constructing, altering, or renovating a commercial property.
So the city doesn’t care which word you use. Your budget does. Here’s the short version: renovation is subtractive first, additive second, and build-out is additive the whole way through.
Second generation space is usually the fastest opening
“Second generation” means a space that was already finished out for a use like yours. A former salon becoming a salon. A former restaurant becoming a restaurant. The prior tenant’s infrastructure is still in the walls.
That infrastructure is where the money hides. In a restaurant, the hood system, grease trap, walk-in refrigeration, upgraded electrical, and HVAC are the expensive line items, and in second-generation space those systems transfer to the new operator at a fraction of replacement cost. The same Modern Restaurant Management piece, by restaurant broker Robin Gagnon, notes that it’s not unusual for a new build-out to take nine to eighteen months to open, while a second-gen space may need only cosmetic front-of-house work and new signage.
Second-generation space is fast because someone else already paid for the boring parts.
The math keeps getting more lopsided. Gagnon cites the Turner Building Cost Index showing nonresidential construction costs up roughly 30 percent since 2020, with a quick-service restaurant that once cost $750,000 to build now approaching $1 million. Meanwhile CBRE’s 2026 U.S. retail outlook expects new construction to remain limited due to financing constraints, high costs and little land availability, which keeps existing space in demand.
Second-gen has a catch, though: you inherit the last tenant’s decisions. Their restroom count, their panel capacity, their ceiling height. If your concept needs something they didn’t have, you’re doing a renovation with build-out pricing on that one item.
What actually drives cost and time
Whichever path you’re on, the same handful of scopes decide the budget. Walk the space with this list in hand.
Demolition. Renovation starts here; build-out mostly skips it. Demo uncovers surprises: abandoned conduit, a slab trench from an old plumbing run, a ceiling stuffed with dead cabling.
MEP reuse or replacement. Mechanical, electrical, and plumbing are the biggest swing. Reusing an existing 5-ton rooftop unit is cheap. Adding a second one because your podcast studio needs isolated air handling is not.
Ceilings. Open structure, new grid, or hard lid? Each one changes the lighting package, the sprinkler layout, and the acoustics.
Restrooms. Adding a fixture means opening the slab. Adding an accessible restroom where there wasn’t one means opening the slab and redrawing the floor plan around a turning radius.
Grease interceptors. Food service in a space that never had it means an exterior interceptor, a sanitary line under the slab, and a health department review.
Electrical service. Barber stations, medical equipment, a cook line, EV chargers in the lot. If the existing panel is full, you’re pulling a new feeder from the building’s service, and the utility’s calendar now controls yours.
Quick reality check: none of these items care what your project is called. They care about what exists today and what you need on opening day. The gap between those two states is the project.
Change of occupancy: the trigger that rewrites your scope
Now for the part that surprises owners. Building codes sort every space into an occupancy group: business, mercantile, assembly, and so on. When your use moves the space into a different group, the code treats the project differently even if you barely touch the walls.
The International Existing Building Code, the model code for work in existing buildings (Texas edition text hosted by UpCodes), says a change of occupancy shall not be made to any structure without the approval of the code official, and a new certificate of occupancy is issued once the requirements for the change are met. Where the occupancy classification itself changes, a separate run of code sections applies, covering fire protection, egress, structural, and MEP.
Accessibility rides along. Under the same code, existing buildings that undergo a change of group or occupancy must meet the alteration accessibility rules: an accessible route to the primary function area, plus the restrooms and drinking fountains that serve it.
There’s a cost cap: the accessible route work isn’t required to exceed 20 percent of the cost of the alterations affecting the primary function area. Twenty percent of a large renovation is still real money. Plan for it.
Dallas adds its own layer. The city defines a change of use as any proposed change to the use of a property or an intensification of an existing use that creates more or different impacts to the site or surrounding properties.
If your proposed use differs from the previous one, the application is routed to the Building Code and Zoning teams, and you may need to upload a site plan, floor plan, and possibly a parking analysis. Same use as before? Inspections can be scheduled without delay once the application is approved and paid.
The code official doesn’t care what your lease calls the space. It cares what happens inside it.
So a retail-to-restaurant conversion in an existing finished suite is technically a renovation. Code-wise, it behaves like a build-out with a parking study attached.
Texas accessibility review kicks in at $50,000
Texas adds a state-level review that out-of-state owners have usually never met. The Texas Department of Licensing and Regulation enforces the 2012 Texas Accessibility Standards, effective March 15, 2012.
According to TDLR’s Architectural Barriers FAQ, projects with an estimated cost of $50,000 or more must be registered with the department and submit a full set of construction documents. Under $50,000 you skip registration, but the project is still required to comply with TAS.
In practice that means grab-bar heights, door clearances, the counter height at your reception desk, and the slope of the route from the accessible parking stall. Build it wrong and you’re rebuilding it.
Permits and the CO in Dallas and Frisco
Every DFW city runs its own permit desk, and the details differ. Two examples.
Dallas. Building permits and certificate of occupancy applications go through the DallasNow portal; to get a CO you submit the application and a Land Use Questionnaire through DallasNOW along with the fee.
One fresh wrinkle: effective June 1, 2026, commercial projects must schedule plumbing and mechanical rough inspections together on the same day, and the finals together as well. Your plumber and your HVAC sub now need to be ready the same morning.
Frisco. Frisco draws a clean line between two paths. If you’re a new tenant in an existing business and you’re not building anything, you apply for a certificate of occupancy directly, and inspectors do a general life safety inspection covering light, heat, ventilation, sanitation and egress.
But per the city’s Form 873, if you’re changing building elements such as wall construction or equipment installation, a CO application doesn’t apply; you submit a Commercial Building Permit Application, and that permit concludes with a Certificate of Occupancy. Frisco lists interior finish outs among the commercial permits it reviews electronically.
Two details I like on that form: the courtesy CO inspection and the courtesy fire inspection can be scheduled for the same day, and the gas release inspection spells out the test itself, a 3 lb test on a 5 or 6 lb gauge for low-pressure systems. That’s the level of detail your contractor should be reading.
Plano, Allen, Irving, and Celina each run their own versions; a good contractor keeps a one-page cheat sheet per city.
Renovating while you’re still open
Sometimes closing isn’t an option. A restaurant that stops serving for eight weeks loses its cooks along with its revenue. A clinic with booked patients can’t just lock the door.
Phasing solves it, at a price. Work happens in zones, usually overnight or in half-shifts, behind temporary partitions with negative air. The schedule stretches, and the general contractor earns the fee by tracking who’s in which room on which night.
Good contractors handle this with a written phasing plan tied to your business hours and a single point of contact who texts you before anything loud starts. If you’re weighing a phased renovation against a clean shutdown, ask for both schedules priced side by side as part of the tenant improvement conversation, and ask to see the step-by-step process the contractor uses to keep an occupied job moving.
A decision framework you can run in ten minutes
Here’s how we frame it at MASACO when an owner brings us a space. Six questions, in order.
- What’s there today? Shell, first-gen finished, or second-gen matched to your use?
- Does your use change the occupancy group? If yes, budget for code upgrades and the accessibility path-of-travel work no matter how light the finish scope looks.
- Which of the six cost drivers move? Demo, MEP, ceilings, restrooms, grease, electrical service. Mark each one reuse, modify, or new.
- Is the project over $50,000? Then TDLR registration and TAS review go on the schedule from day one.
- Can you close, or do you have to phase? Phasing adds time and coordination cost. Closing adds lost revenue. Put a dollar figure on each.
- What does the landlord pay for? Your allowance and the lease’s definition of landlord work decide what’s yours to fund; see our guide to tenant improvement allowances.
Answer those six and the renovation-versus-build-out question mostly answers itself.
Two real jobs, side by side
The cleanest way I can show the difference is two projects we’ve finished. Both small. Both on time. Completely different animals.
Calibration Brain & Body, Frisco: the renovation. About 4,250 square feet of existing commercial space, converted into a wellness and media studio on a five-week expedited schedule. The bones stayed.
We demolished selectively, ran new flooring and paint throughout, upgraded the electrical and installed LED flat panels, and turned the old waiting area into a podcast studio lined with acoustic wall panels. A custom front desk, interior signage, and a custom-built water filtration fountain finished it. Every item on that list sits inside a building that was already a building, so the money went into finishes, electrical, acoustics, and custom pieces rather than core infrastructure.
What made it hard: the specialty trades (electrical, acoustics, millwork, plumbing for the fountain) all had to run at the same time without one undoing another’s work. Five weeks is only possible when the sequence is planned to the day. The full scope is on the Calibration project page.
Fade & Style Barber Shop, Allen: the build-out. About 1,500 square feet, taken from shell condition to a working barber shop in six weeks. Smaller footprint, but everything a client would touch was new: electrical and lighting layout, plumbing for the barber stations, flooring, paint, and the full finish-out, with every subcontractor and city inspection running through us.
The curveball came from a finish, not a system. The PVC wall panels specified for the station walls needed fire marshal testing documentation before the city would sign off on the certificate of occupancy. We went straight to the supplier and the city, got the compliance data in hand, and the grand opening date didn’t move (details on the Fade & Style project page).
Five weeks and six weeks. Both on time. Completely different jobs.
Now look at what the timelines hide. Calibration was nearly three times the square footage and finished a week faster, because the renovation reused the expensive infrastructure. Fade & Style was roughly a third the size and took longer, because a shell has nothing to reuse.
Square footage is a poor predictor. Starting condition is a good one.
One more, because it’s the phasing case: Pizza Twist in Irving, a 2,000-square-foot franchise restaurant we finished in six to eight weeks while the restaurant stayed open. Zones, nights, and a lot of plastic sheeting. It works when it’s planned as a phased job from the first meeting rather than converted into one halfway through.
Which one fits your space
If your space already matches your use and the systems are sound, a commercial renovation is usually the shorter, cheaper path, and be suspicious of any proposal that treats it like a shell. If you’re starting from concrete and stubs, it’s a build-out, and the first month belongs to MEP rough-in. If your use changes the occupancy group, budget like a build-out even when the finishes look light.
We work through all of this in the first two steps of our process: Understand, where we walk the space with you and map what’s reusable, and Visualize, where 3D renderings settle what “done” looks like before anything gets priced. The proposal that follows is fixed-scope and organized by trade with allowances called out, so you can see which of the six cost drivers are moving and why. From there you get one project manager, a written photo update every week, and a close-out package with the as-builts, permits, inspections, CO, and warranties.
Have a space and a lease in hand? Bring them both. Book a consultation and we’ll tell you on the first walk-through whether you’re looking at a renovation or a build-out, and what that means for your opening date.
