The most common way a restaurant buildout goes wrong is not a cost overrun on construction. It is that the operator financed the construction and nothing else. The doors open, the dining room is beautiful, and by week six the business is running on the founder's credit cards because there was never a line item for the eleven weeks it takes a new restaurant to find its volume. Contractors get paid. Ramp does not have a vendor invoice, so it does not get budgeted.
An underwriter looking at a buildout request is doing one thing above all: checking whether the total number is the real total. Not the hard costs, which are easy to quote, but everything between signing the lease and the first month the unit covers itself. This guide walks through how that number is built, how draw funding actually works, what a lender is looking at in the contractor package, and why the reserve line is the one you should defend hardest.
Start with what kind of space you took
Cost per square foot is meaningless without knowing what is already in the box. The single largest variable in a restaurant buildout is whether the space has ever been a restaurant before, because the expensive infrastructure: grease interceptor, gas service, exhaust and make-up air, sprinkler coverage, ADA restrooms, adequate electrical service: is infrastructure, not finish.
| Space type | What is typically already there | What it usually means for the budget |
|---|---|---|
| Second-generation restaurant | Hood, grease interceptor, gas, restrooms, floor drains | Lowest cost per foot; risk is inherited equipment and dated systems |
| Second-generation retail | Shell finishes, restrooms, basic electrical | Full kitchen infrastructure has to be added |
| White box | Walls, floor, HVAC, restrooms, utilities stubbed | Everything above the shell is yours |
| Cold shell | Slab, walls, utility stubs at the property line | Highest cost and the longest permitting path |
| Owned building, conversion | Varies | Structural and code work often exceeds the kitchen budget |
The trap in second-generation space is assuming inheritance equals usability. A hood sized for the last tenant's six-burner range may not cover your charbroiler. A grease interceptor sized for a sandwich shop may not pass for a full kitchen. Have a code consultant or your general contractor confirm the existing systems against your menu before you sign the lease, not after.
Building the real number
A credible buildout budget has six blocks. Operators typically bring the first two and forget the rest, which is why so many requests get resized upward mid-underwriting.
Hard costs
Everything the general contractor builds: demolition, framing, mechanical, electrical, plumbing, fire suppression, finishes, millwork, signage. This is the line with a bid attached, and it is the line the desk trusts most because it is documented.
Equipment, furniture and fixtures
Kitchen line, refrigeration, warewashing, bar equipment, dining room furniture, POS hardware, smallwares. Some of this is collateral with a resale market and some is not, which affects how it can be financed. That distinction is worth understanding in detail before you structure the request.
Soft costs
Architecture, engineering, kitchen design, permits, impact and utility connection fees, expediting, insurance during construction. In dense jurisdictions this block runs larger than owners expect, and utility connection fees in particular have surprised many first-time operators.
Pre-opening cost
Rent during construction, manager and chef salaries during hiring and training, staff training labor, menu R and D, friends-and-family services, opening marketing, opening inventory. None of it generates a dollar of revenue and all of it is required.
Contingency
Ten to fifteen percent of hard costs is standard practice for a reason. A request with no contingency line reads as either inexperience or an attempt to keep the number down, and both cost credibility.
Post-opening working capital
The ramp reserve. The one that gets cut first and should not be cut at all.
The ramp is the line item nobody funds
New restaurants do not open at run-rate volume, and the ones that open hot frequently give some of it back after the novelty traffic passes. Meanwhile the cost structure is at its worst: labor is inefficient because the team is new, food cost is high because the kitchen is still learning the menu, and waste runs above steady state.
Size the reserve by modeling the shortfall month by month rather than picking a round number. Take your fixed obligations (rent, insurance, salaried management, base utilities, debt service) and subtract the contribution you expect at each month's realistic volume. The sum of the negative months is your reserve. Then add a month, because ramp assumptions are where optimism concentrates.
How buildout money actually funds
Construction financing does not usually arrive as a lump sum. It funds in draws against completed work, which protects the lender from paying for a project that stops halfway and protects you from paying interest on money sitting idle. It also creates administrative work that new operators consistently underestimate.
A typical draw cycle runs: contractor submits a pay application showing percentage complete by line item; an inspector or the lender's representative verifies it; lien waivers are collected from the general contractor and subs for the prior draw; funds release. Each cycle takes time, and requirements vary by lender and program. Retainage, commonly a percentage of each draw held back until final completion and sign-off: means your contractor is carrying part of the cost until the end, and your contract should say so explicitly.
The practical consequence is that you need enough liquidity to stay a step ahead of the draw cycle. Deposits on long-lead equipment, permit fees and the first mobilization payment often come due before the first draw clears.
What the desk wants from the contractor package
A buildout request is partly a construction credit, and construction credits get evaluated on execution risk as much as on cash flow. The package below is not busywork, every item answers a specific question about whether the project finishes on budget.
The buildout submission package
- Executed lease or letter of intent, with the tenant improvement allowance terms stated plainly.
- Signed general contractor agreement with a fixed or guaranteed maximum price, not a verbal estimate.
- Line-item budget reconciling to the contract, with contingency shown as its own line.
- Construction schedule with permit milestones and a target opening date.
- Architectural and MEP drawings, plus the kitchen equipment layout.
- Equipment quotes with model numbers, separating attached fixtures from movable equipment.
- Sources and uses statement showing every dollar in and every dollar out, including your equity injection.
- Pre-opening budget and a month-by-month ramp model with the reserve calculated from it.
- Operator resume and the resumes of the chef and general manager, with concept-relevant experience.
- Personal financial statement, tax returns, and a debt schedule covering every existing obligation.
Two items on that list carry disproportionate weight. A guaranteed maximum price contract materially reduces the risk that the project outruns the budget. And a contractor with real restaurant experience (hoods, grease, health department sign-off, gas piping inspections) will finish faster than a cheaper general contractor learning the category on your dime.
Equity, and why the desk asks about it first
Buildout financing rarely covers the full project. The operator is expected to put real money in, and requirements vary by lender, program and whether the project is a first location or an addition to an operating group. There are two reasons, and only one is about loss coverage.
The first is straightforward: leasehold improvements are weak collateral. If the restaurant closes, the improvements stay with the building. Equity is the cushion. The second reason is behavioral. Operators with meaningful capital at risk finish projects, cut menu items that do not work, and make hard staffing calls faster than operators playing entirely with borrowed money. Underwriters have watched both, and they price accordingly.
Expansion units are a different credit than a first location
If you already operate one or more units, you have something a first-time operator does not: proof. An existing unit generates the historical cash flow that can be underwritten, and a second location is evaluated substantially on the performance of the first.
That cuts both ways. An expansion request will be tested against whether the existing units can absorb a bad opening. If unit one is running thin coverage, funding unit two puts both at risk, and a careful desk will say so. The strongest expansion files show a stable existing operation, a management layer that does not depend on the owner standing in the dining room, and a reserve sized so that a slow opening is survivable rather than existential.
How much should I budget for contingency?
Ten to fifteen percent of hard costs is the common range, and second-generation conversions justify the upper end because demolition reveals surprises. Show it as its own line rather than padding other lines. A budget with no contingency reads as incomplete rather than lean.
Can the tenant improvement allowance count toward my equity?
It reduces the total capital required, which helps, but it is generally treated as a source of funds rather than as operator equity. Check the payment mechanics too, most allowances are reimbursed after completion and lien waiver delivery, so you fund the work first and carry the gap.
How long does buildout financing usually take to close?
It depends on program, documentation completeness and whether real estate is involved, and it varies by lender and file. What reliably shortens it is having the lease executed, the GC contract signed, drawings complete and permits filed before submission. What reliably lengthens it is a moving budget or a contractor who has not been selected yet.
What happens if the project runs over budget mid-construction?
You are expected to cover it, which is precisely why the contingency line and the equity cushion exist. Additional funding mid-project is possible but slow, and stopping work is expensive: contractors demobilize, subcontractors take other jobs, and restarting costs both money and weeks. Solve overruns from the contingency you already funded.
Is a first-time operator financeable at all?
Yes, but the file is built differently. Relevant industry experience, meaningful equity, a conservative sales projection with a defensible basis, a strong lease and an experienced contractor carry more weight when there is no operating history. First-time files are also where reserve sizing gets scrutinized hardest, because there is no track record to draw on.
How should I project sales for a location that does not exist yet?
Build it bottom-up: seats, turns by daypart, average check by daypart, days open. That is a model an analyst can interrogate. A top-down number derived from what a comparable restaurant across town supposedly does is not verifiable, and it invites a discount rather than a discussion.
Where to start
Before you request anything, build the sources and uses on one page. Every dollar in (your equity, the TI allowance, the financing) and every dollar out, across all six budget blocks. If the two sides do not balance without borrowing from the contingency or the reserve, the project is underfunded and the underwriting will find it.
Then build the month-by-month ramp model and let it size the reserve for you. Those two documents make the difference between a request that gets resized halfway through and one that funds at the number you asked for.
