Restaurant Build-Out
A restaurant build-out runs two approvals at once: the building permit and health department plan review. Hood exhaust, makeup air, the grease interceptor and floor finishes usually decide the schedule.

Overview
Restaurant Build-Out
Four things decide whether a space is cheap or brutal to convert: the exhaust hood, the grease interceptor, the incoming gas capacity and the electrical service. Finishes and furniture feel like the project, but they are the small end of the money. Walk any candidate space with those four in hand before you talk about square footage or rent.
A second-generation restaurant can save months, but only if what the last operator left is usable for your menu. A hood listed for a shorter cook line, an interceptor sized for a smaller seat count, or a gas meter matched to the old appliance schedule all have to be replaced, and replacing them means roof work, trenching or a utility request that no contractor controls.
The things that actually decide this job
Exhaust and makeup air have to balance
A Type I hood over a cook line moves large volumes of air, and every cubic foot must be replaced by a tempered makeup air unit interlocked to the fans. Get this wrong and the dining room goes negative: doors drag, smoke rolls off the line, pilot lights die and the front door leaks humid outside air all day. Balance is verified at final inspection, so plan the units together.
Grease interceptor sizing and location
Sizing follows fixtures, seats and menu under local rules, and an outdoor gravity interceptor means excavation, plumbing review and truck access for pump-outs. Indoor hydromechanical units only serve limited loads. Just as important is which fixtures actually tie to the grease line: three-compartment sink, prep sinks, dish machine, floor sinks and mop sink typically do, and rerouting them later means cutting slab.
The finish schedule is a permit document
Health review reads floors, walls and ceilings as equipment. Surfaces in food prep areas must be smooth, durable, non-absorbent and cleanable: quarry tile or resinous floor with coved base, washable wall panels behind the cook line, sealed or vinyl-faced ceiling tile. No exposed wood shelving, no carpet in prep, no unsealed concrete. Choose these before drawings go in, because a substitution restarts the review.
Utilities, sized for the menu
Total appliance BTU may exceed the meter that served the last tenant, and a service upgrade runs on the utility calendar. Electrical loads stack up fast from refrigeration, hoods, makeup air, dish machine and hot line equipment. Water heating is sized on recovery for the peak dish hour, not tank gallons. Get the equipment schedule locked early, since every one of those calculations depends on it.
Practical considerations
Two reviews, plus the fire marshal
Health plan review is separate from the building permit and generally happens before construction, with its own submittal of layout, equipment cut sheets and finish schedule. The hood suppression system is reviewed and tested by the fire authority. Any one of the three can hold your opening. Whether a city or county health authority has jurisdiction depends on the address, so confirm at the start.
Bars and beverage service
A bar adds under-counter sinks, glass washers, ice machine drainage to indirect waste, floor drains behind the bar and beer-line routing to a walk-in that may sit across the building. Alcohol permitting is a state process on its own timeline and is not part of the build, but plan approvals often want the bar layout and dispensing details, so draw the bar properly rather than as a rectangle.
Humidity, odor and the neighbours
Dish areas and hot lines put heat and moisture into the space, and Gulf Coast air is already carrying moisture in. Under-ventilated dish rooms sweat ceilings and rust hardware, and a negative building pulls cooking odor into adjoining tenant suites. Dedicated dish exhaust, correct restroom exhaust, and a building held slightly positive when the hoods are off are what keep complaints down.
Older pad buildings and floodplain
Freestanding restaurant buildings often sit on older commercial pads, some of which fall in a mapped floodplain. If your improvement cost reaches half the structure’s pre-improvement market value, the whole building can be pulled into floodplain compliance, which changes elevation and equipment placement. Only the floodplain administrator for that address gives a binding determination, and it is worth getting in writing early.
At a glance
| Kitchen element | What to verify in an existing space | Why it drives the schedule |
|---|---|---|
| Type I hood | Listed length over your line, CFM, UL 300 suppression | Replacement means roof curb, alarm tie-in, witnessed test |
| Makeup air unit | Matched CFM, working heat and cool, interlock | Long-lead equipment; balance is checked at final |
| Grease interceptor | Size against new seat count, truck access | An outdoor unit means excavation and plumbing review |
| Grease waste piping | Which fixtures actually tie in today | Rerouting means saw-cutting the slab |
| Gas service | Meter capacity against total appliance BTU | Utility upgrades run on their calendar, not yours |
| Walk-in cooler | Condenser location, line routing, floor and drain | Touches structure, roof, electrical and plumbing at once |
Common questions
Is taking over a former restaurant really faster?
It can be, and it is also the most common way people underestimate a project. Check four things before you assume savings: is the hood listed and long enough for your cook line, is the interceptor sized for your seat count and menu, does the gas meter cover your appliance schedule, and does the electrical service have capacity and panel space. If all four hold, you are ahead by months. If two fail, you are building a kitchen anyway, inside a space that also needs demolition.
How is health plan review different from the building permit?
They answer different questions. The building permit asks whether the construction is safe and code-compliant: structure, egress, electrical, mechanical, plumbing. Health review asks whether the space can produce food safely: equipment layout, hand sink placement and reach distances, indirect waste and air gaps at food equipment, warewashing, dry storage, finish materials and employee facilities. You submit to both, they inspect separately, and the health authority also inspects before opening. Neither one substitutes for the other.
Do I need a grease interceptor if I have no fryer?
Usually yes, though the size can change. Grease is not only fryer oil. Dish machines, three-compartment sinks and prep sinks carry fats, oils and grease from cleaning and cooking of any kind. Requirements come from the local ordinance and are commonly triggered by the type of food establishment, not by whether you own a fryer. A reheat-only or beverage-forward concept can sometimes justify a smaller unit, but that decision belongs to the reviewing authority, in writing.
How long does a kitchen build-out actually take?
It depends, and the drivers are more useful than an average. Health and building review cycles run in parallel and each correction restarts a wait. Hoods and makeup air units are ordered, not stocked. Gas meter upgrades and electrical service work follow the utility. Walk-in coolers and custom stainless are lead-time items. Once those dates are on paper, the actual construction is the predictable part. Order long-lead equipment as soon as the layout is fixed, not when permits land.
Can I keep the dining room open while the kitchen is rebuilt?
Rarely, and it is usually a false economy. Kitchen work means the interceptor, gas, hood and often the electrical service are down, and a food establishment cannot operate without functioning warewashing, hand sinks and hot water. Dust and demolition next to food service invite a health problem you do not want. Where phasing does work, it is a dining-room refresh done in halves while the kitchen runs, not the reverse. Call (832) 513-5639 to talk through phasing before you plan a soft close.
