How much should I budget for the landlord's cost to fund my buildout in 2027?

The numbers you should expect

The landlord's cost to fund your buildout is almost never a lump sum written on a check. It is a negotiated line in the lease called the tenant improvement allowance, quoted in dollars per rentable square foot, and it is priced by the landlord as a capital investment they expect to recover through your rent over the term. That framing matters for your budget, because it means the allowance you are offered is a function of how much rent you commit to paying, not a function of how much your buildout actually costs.

For planning purposes in 2027, work with these bands. Second‑generation office space — meaning a suite that already has ceilings, lighting, HVAC distribution, restrooms in the core, and a usable floor plan — typically draws an allowance in the $20 to $40 per square foot range on a five‑year term. First‑generation or shell office space, where you are building partitions, ceilings, mechanical distribution, and finishes from a bare slab, pushes the allowance into the $50 to $90 per square foot range on a longer term, often seven to ten years. Retail inline space in a strip center commonly lands between $15 and $50 per square foot, and landlords in that segment frequently substitute free rent for cash. Restaurant space is its own world: the buildout cost runs $200 to $500 per square foot for a full‑service concept with a hood, grease interceptor, walk‑in cooler, and gas service, while the allowance rarely exceeds $50 to $100 per square foot, leaving the tenant to carry the majority. Medical and dental suites run $150 to $350 per square foot to build, with allowances in the $50 to $100 range for a ten‑year commitment. Warehouse and light industrial is the cheapest to build and the stingiest on allowance — often $5 to $20 per square foot, because the landlord is providing a box and expects you to fit it out.

Now do the arithmetic that actually drives your budget. Take a 4,000 square foot second‑generation office suite. A $35 per square foot allowance is $140,000. If your general contractor prices the work at $95 per square foot — a realistic 2027 number for a modest office fit‑out with new carpet, paint, a few glass fronts, some demo, and light electrical — your hard cost is $380,000. The landlord covers $140,000, you cover $240,000. That is the gap you budget for, and it is the number most tenants underestimate by half because they anchor on the allowance headline rather than the delta.

Then add the soft costs the allowance frequently does not cover, or covers only partially. Architectural and engineering drawings for a suite that size run $3 to $8 per square foot, so $12,000 to $32,000. Permit fees vary wildly by jurisdiction but budget 1% to 3% of hard cost, plus plan review time. A project manager or owner's representative, if you hire one, is typically 3% to 6% of construction cost, and for a first‑time tenant on a six‑figure buildout that fee usually pays for itself in change‑order discipline alone. Furniture, fixtures, and equipment are almost always excluded from the allowance and are your cash: $2,000 to $6,000 per workstation fully loaded for office, far more for specialized equipment. Low‑voltage cabling, security, and AV run $3 to $10 per square foot and are a classic exclusion. Move costs, signage, and your own IT gear round it out.

A defensible 2027 budget for that 4,000 square foot example looks like this. Hard construction: $380,000. Design and engineering: $22,000. Permits and fees: $9,000. Low voltage and AV: $24,000. Furniture: $60,000. Contingency at 12% of hard cost: $45,600. Total project: roughly $540,600. Landlord allowance: $140,000. Your out‑of‑pocket: roughly $400,600, or about $100 per square foot. Notice that the allowance covered 26% of the true all‑in cost even though it looked like it covered 37% of construction. That spread between "percent of hard cost" and "percent of total project" is the single most common budgeting error tenants make, and it is why you should always model the landlord contribution against the total, never against the contractor's bid alone.

One more number to hold: contingency. Twelve percent is a reasonable floor for a straightforward office fit‑out in a building you have not opened the ceiling on yet. Fifteen to twenty percent is more honest for restaurant, medical, or any space where you are touching mechanical, electrical, and plumbing systems of unknown age. In older buildings, budget separately for the discovery items nobody prices at bid — asbestos or lead abatement in pre‑1985 construction, undersized electrical service, a roof that cannot carry a new rooftop unit, or an accessibility upgrade triggered the moment you pull a permit. Any one of those can add $15,000 to $100,000, and none of them will come out of the landlord's allowance unless your lease explicitly makes building‑system deficiencies the landlord's obligation.

What drives those numbers

The allowance a landlord offers is not generosity, it is underwriting. The landlord runs a simple model: total capital outlay for the deal, divided by the net effective rent they will collect over the term, has to clear a return threshold. Every dollar of allowance is a dollar they need to earn back, so the size of your buildout funding is driven mechanically by four inputs — term length, rent rate, your creditworthiness, and the landlord's alternative use for the space.

Term length is the strongest lever. A landlord amortizing $200,000 of improvement cost over a three‑year lease needs roughly $67,000 a year of incremental rent to break even before any return on capital. Over ten years, the same $200,000 needs about $20,000 a year. That is why allowance offers scale almost linearly with term, and why the fastest way to increase the landlord's contribution is to add years rather than to argue. As a rough planning heuristic in most markets, expect roughly $6 to $12 per square foot of allowance per year of lease term for office space — so a five‑year deal supports $30 to $60, a ten‑year deal supports $60 to $120. Retail and industrial run lower per year; the same logic applies with smaller coefficients.

Rent rate is the second driver, and it is the one tenants trade away without realizing it. Allowance and rent are two ends of the same rope. A landlord will happily give you an extra $25 per square foot of buildout funding in exchange for $3 per square foot per year more in base rent over ten years — that is $30 of additional rent for $25 of capital, and they get it back with a spread. Whether that trade is good for you depends entirely on your cost of capital. If you cannot borrow at all, taking the allowance and paying the rent premium is rational financing. If you have cash or an SBA 7(a) loan at a reasonable rate, funding the buildout yourself and holding rent down is usually cheaper over the term, and it keeps your rent comparable if you ever want to sublet or assign.

Creditworthiness sets the ceiling. A landlord funding a buildout for a two‑year‑old LLC with no operating history is making an unsecured loan to a startup. Expect them to demand a personal guarantee, a larger security deposit, or a letter of credit before they release a dollar. A tenant with three years of audited financials and a strong balance sheet gets the allowance with a burn‑off guarantee or none at all. If you are early‑stage, budget for the collateral, not just the construction: a six‑month letter of credit on a $9,000 monthly rent is $54,000 of cash you cannot spend on the buildout.

Market conditions and space condition are the last inputs. In a submarket with high vacancy, landlords compete on concession packages and allowances stretch. In a tight submarket they contract, and the landlord may offer the space as‑is. Space that is already close to your required layout — a former professional office becoming a new professional office — costs less to convert and needs less allowance. A change of use, like converting retail to medical or office to a commercial kitchen, triggers new code requirements, new mechanical loads, and often a new occupancy classification, and that is where costs escalate fastest.

There is a fifth input that rarely gets discussed but changes your budget materially: who holds the construction contract. In a landlord‑build deal, the landlord hires the contractor, manages the job, and delivers the finished space — and typically charges a construction management fee of 3% to 5% on top, sometimes on the full cost including your over‑allowance contribution. In a tenant‑build deal, you hire the contractor and draw against the allowance on completion. Landlord‑build shifts schedule risk to the landlord and saves you management time, but you lose control of scope, cost, and subcontractor selection, and you will pay the CM fee. Tenant‑build gives you control and competitive bidding, but you carry the cash flow, the schedule risk, and the permit process. For buildouts under roughly $150,000 in a straightforward suite, landlord‑build is often the better use of a small operator's time. Above that, or anywhere the finishes matter to your brand, tenant‑build usually wins on cost and quality.

Lease, TI allowance, and negotiation levers

The number in the letter of intent is not the number you get. What you actually receive is governed by the work letter, which is the exhibit to the lease that defines the improvements, the allowance, the approval process, and the disbursement terms. Read it as carefully as you read the rent schedule, because three or four clauses in that exhibit determine whether your $140,000 allowance is worth $140,000 or $95,000.

Start with what the allowance can be spent on. Landlords routinely restrict it to "hard construction costs of building‑standard improvements affixed to the premises." Under that language, your architect's fee, your permit expediter, your cabling, your security system, and every piece of furniture are excluded. Negotiate the definition to include soft costs explicitly — architecture and engineering, permits, project management, low voltage, and, if you can get it, a stated portion for furniture and moving. Getting soft costs inside the allowance is often worth more than getting the headline number raised by $5, and it is an easier ask because it does not change the landlord's total capital number.

Second, look at the disbursement mechanics. The common structure is reimbursement after substantial completion, upon delivery of lien waivers, a certificate of occupancy, and paid invoices. That means you float the entire construction cost for 60 to 120 days. On a $380,000 job, that is real working capital, and it is why a line of credit or an SBA loan should be arranged before you sign, not after. Push for progress draws — monthly disbursements against percentage of completion, matching how your contractor bills you. If the landlord insists on completion funding, ask for a partial draw at 50% completion. Also confirm the deadline: many work letters say any allowance not requisitioned within nine or twelve months of delivery is forfeited. Permit delays alone can eat that window.

Third, the over‑allowance provision. If the project costs more than the allowance, most leases require you to deposit the excess with the landlord before construction starts, or to fund your share first with the landlord's money coming last. Know which structure you are in, because "landlord funds last" means you spend $240,000 of your own cash before the first landlord dollar appears.

Now the levers that actually move the number. Amortized additional allowance is the most useful and the least used: ask the landlord to fund an extra $20 to $40 per square foot, repaid through the lease as additional rent at a stated interest rate, commonly in the high single digits to low teens. It converts a capital problem into an operating expense and is usually cheaper and faster than unsecured borrowing. Structure it as a separate line so it is visible and so you know exactly what it costs. Free rent is the second lever — three to six months of abatement on a five‑year office deal is standard, and abated rent is cash you keep and can redirect to the buildout, with no interest and no strings. Convert it mentally: six months of abated rent on $9,000 a month is $54,000, comparable to $13.50 per square foot of additional allowance on a 4,000 square foot suite.

Third, an as‑is delivery credit. If you are gutting the space anyway, the landlord's planned refresh has no value to you. Ask them to convert their intended paint‑and‑carpet spend into allowance dollars. Fourth, landlord's work as a separate obligation. Distinguish between your improvements and base building work: HVAC in good working order, a code‑compliant electrical panel of stated capacity, ADA‑compliant common areas and restrooms, a watertight roof, and a demised, sprinklered shell. Put those in the lease as landlord obligations delivered at landlord's cost, not out of your allowance. This is the highest‑value clause in the entire negotiation for older commercial buildings, because it moves the unknown‑condition risk off your budget. Add a warranty period — the landlord repairs base‑building failures for the first twelve months at their expense.

Fifth, control the construction management fee. If the landlord builds, cap the CM fee at 3% and apply it only to the allowance portion, not your over‑allowance spend. Sixth, get restoration and removal obligations resolved up front. A lease that requires you to remove all improvements and restore to shell at expiration is a five‑figure liability you are agreeing to fund years from now. Negotiate that you have no removal obligation for improvements shown on the approved plans, with removal limited to specifically identified items like vaults, internal stairs, or specialty equipment.

Finally, negotiate the approval process itself. If the landlord has consent rights over your plans, your contractor, and your changes, add "not to be unreasonably withheld, conditioned, or delayed" and a deemed‑approval clock — ten business days for plan review, five for changes, after which silence equals approval. Unmanaged approval delay is the most common cause of blowing the allowance requisition deadline.

Sequencing the buildout

Budget accuracy comes from sequence, not from a spreadsheet. If you price the job before you have a test fit and a base‑building condition report, your number is a guess and your allowance negotiation is uninformed. Run it in this order.

Begin with a test fit before you sign anything. An architect will produce a space plan for a modest fee, often reimbursed by the landlord or the broker, showing whether your headcount, offices, and program actually fit the suite. The test fit tells you the linear feet of new partition, the number of doors, and whether you need to relocate ductwork or add electrical — the three biggest drivers of a fit‑out estimate. Take the test fit to a contractor for a budget estimate before the letter of intent is finalized. A rough order of magnitude at this stage, plus or minus 20%, is enough to negotiate an allowance intelligently instead of accepting whatever is offered.

Second, get a base‑building condition assessment. Have a mechanical engineer inspect the HVAC units — age, tonnage, refrigerant type, service records. Have an electrician confirm panel capacity and available spare breakers against your actual load, including any equipment. Confirm the sprinkler head layout against your planned ceiling and partition changes, because relocating heads is a permit item and adds cost. Ask for the building's most recent accessibility assessment. Every deficiency you find here becomes a landlord obligation you negotiate in the lease rather than a change order you pay for in month three.

Third, execute the lease with a work letter that reflects what you learned. Fourth, complete construction documents and submit for permit. Budget four to twelve weeks for plan review depending on jurisdiction, longer for change of use, health department review for food service, or any project triggering fire marshal sign‑off. Fifth, competitively bid the documents to three qualified contractors on identical scope. The spread between the low and high bid on a fit‑out is routinely 15% to 25%, which on a $380,000 job is $57,000 to $95,000 — more than most tenants gain from an entire allowance negotiation. Insist on a line‑item bid form so you can compare apples to apples and see where each contractor is carrying allowances and contingencies.

Sixth, execute a contract with a clear change‑order process, a substantial completion date, and, if your rent commencement depends on delivery, liquidated damages or rent offset for late delivery. Seventh, build, with weekly site meetings and a written change‑order log. Eighth, close out: punch list, certificate of occupancy, lien waivers from every subcontractor, warranties, and as‑built drawings. Ninth, requisition the allowance with the complete documentation package the work letter requires. Missing lien waivers are the most common reason a requisition gets rejected and payment slips another month.

Two sequencing traps deserve their own mention. The first is rent commencement. If your lease starts the rent clock on delivery of the premises rather than on substantial completion of your improvements, every week of permit delay is a week of paying rent on a construction site. Negotiate rent commencement tied to the earlier of substantial completion or a fixed outside date, with the outside date extended day‑for‑day for landlord delays and force majeure. The second is contractor cash flow. Your contractor bills monthly and expects payment in 30 days; your landlord reimburses at completion. That mismatch is the working capital gap, and on a six‑month project it can peak at 60% to 80% of the hard cost. Model it month by month before you sign, and secure the financing to cover the peak, not the average.

Related questions

Does the tenant improvement allowance cover furniture and equipment?

Usually not. Most work letters limit the allowance to improvements permanently affixed to the premises. Furniture, movable equipment, and often low‑voltage cabling are excluded unless you negotiate them in explicitly. Ask for a stated soft‑cost carve‑out during the letter of intent stage.

What happens if my buildout costs less than the allowance?

Typically you forfeit the difference. Some leases let you apply a portion of the unused allowance — often capped at $5 to $10 per square foot — against future rent. That conversion right is worth asking for, because it removes any incentive to inflate scope just to use the money.

Is the tenant improvement allowance taxable income to me?

It depends on the structure and your jurisdiction, and it is a genuine tax question, not a lease question. Allowances can be treated as income with an offsetting depreciable asset, or as a reduction in rent expense. Have your CPA review the work letter language before you sign.

How long do I have to spend the allowance?

Commonly nine to twelve months from lease commencement or premises delivery. Miss the deadline and the unspent balance disappears. Permit delays and landlord approval delays routinely consume that window, so negotiate a longer period and a tolling provision for delays outside your control.

Should I take a bigger allowance or lower rent?

Compare against your real cost of capital. If you can fund the buildout at a lower effective rate than the landlord is charging through the rent premium, take lower rent. If you cannot borrow, the allowance is financing you can actually get, and paying for it in rent is rational.

FAQ

How much of the total buildout should I expect the landlord to fund in 2027?

Plan on the landlord covering roughly 30% to 60% of your all‑in project cost for a standard commercial office or retail fit‑out, and considerably less for restaurant or specialty use. Model the allowance against total project cost — including design, permits, cabling, furniture, and contingency — not against the contractor's hard‑cost bid, which is where most tenants overestimate the landlord's contribution by ten to fifteen percentage points.

What is a realistic per‑square‑foot allowance to put in my budget before I have a lease?

For a five‑year second‑generation office deal, budget $20 to $40 per square foot. For a ten‑year first‑generation deal, $50 to $90. Retail inline, $15 to $50. Warehouse, $5 to $20. Then assume the allowance covers hard costs only until a work letter tells you otherwise, and carry every soft cost as your own money.

Can I ask the landlord to fund more than the standard allowance?

Yes — request amortized additional allowance. The landlord advances extra capital and you repay it as additional rent over the term at a stated interest rate. It is common, it is negotiable, and it is frequently cheaper and faster than unsecured borrowing for a new business. Ask for it as a separate lease line item so the cost is explicit and you can compare it to other financing.

Who pays if the building's HVAC or electrical service turns out to be inadequate?

Whoever the lease says, which is why you settle it before signing. Negotiate base‑building condition as a landlord obligation delivered at the landlord's cost and outside the allowance: working HVAC of stated capacity, a code‑compliant panel with defined amperage, ADA‑compliant common areas, and a watertight roof, with a twelve‑month warranty. Inspect first so you know what you are asking for.

When does the landlord actually pay the allowance?

Most commonly after substantial completion, once you deliver paid invoices, unconditional lien waivers from all subcontractors, and a certificate of occupancy — typically 30 to 60 days after that package is complete. That means you finance the entire buildout in the interim. Negotiate progress draws if you can, and arrange the working capital line before construction starts regardless.

How much contingency should sit in the budget?

Twelve percent of hard cost is a floor for a clean second‑generation office suite. Use 15% to 20% for restaurant, medical, or any project touching mechanical, electrical, and plumbing in a building over thirty years old. Carry abatement, code‑triggered accessibility upgrades, and undersized building systems as separately identified risk items, not buried inside the general contingency.
