What is the typical markup a landlord's GC adds to material costs in 2027?

The numbers you should expect

Ask ten commercial tenants what their landlord's GC charged on materials and you will get ten different answers, because "markup" is not one number — it is a stack. The base layer, the one every GC will admit to, is overhead and profit applied to the cost of goods. On a typical tenant-improvement (TI) project in an occupied office or retail building, that lands somewhere in the 10% to 20% band. A 3,000-square-foot office refresh with drywall, carpet, paint, and a handful of light fixtures will often carry material markup near the top of that band — call it 15% to 20% — because the GC's fixed costs (an estimator's time, a purchasing agent, a project manager who has to make the same number of phone calls whether the order is $8,000 or $800,000) get spread across a small base. A 60,000-square-foot floor with a real MEP scope will usually settle at 8% to 12% on materials, sometimes lower on big-ticket equipment packages, because the absolute dollars are large enough to fund overhead without a fat percentage.

That is the visible layer. Underneath it, three other charges routinely masquerade as material cost:

Landlord coordination or construction management fee. This is the landlord's own cut, typically 1% to 5% of hard costs, charged for "supervising" the project. Sometimes it is legitimate — a building engineer really does have to shut down a riser, escort after-hours deliveries, and inspect the fire-alarm tie-in. Often it is a straight kicker to the landlord. It is almost always negotiable in the work letter, and on competitive deals in soft markets it frequently gets waived entirely or capped at a flat dollar amount.

Material escalation contingency. After several years of volatile lumber, steel, copper, and switchgear pricing, most GCs now carry a contingency line specifically for material price movement between bid and purchase. A 2% to 5% escalation allowance is defensible; anything larger should be tied to a named commodity with a published index, not applied blanket to the whole material budget. The critical question is what happens if prices *don't* move — a contingency that is never returned to the tenant is just markup with a friendlier name.

Handling, storage, and small-tools charges. Warehousing material before the space is ready, staging deliveries through a loading dock with a two-hour window, and consumables (blades, fasteners, tape, tarps) get billed either inside general conditions or as a separate percentage. Either is fine; both at once is double-charging.

Add the layers and the *effective* markup on materials — what you actually pay above what the supplier invoiced — commonly runs 18% to 30% on a TI project, even when the GC's stated material markup is 12%. That gap between the stated number and the effective number is the entire negotiation. When a broker or a landlord's rep tells you "our GC only charges 12 on materials," the correct follow-up is not "can you do 10," it is "12 on top of what, and what else rides on the same base?"

For calibration on the adjacent categories, since they move together: subcontractor markup usually runs 5% to 10% (the sub already has profit baked into their number, so the GC is charging for management, not risk), self-performed labor carries a burdened rate plus 10% to 15%, and total overhead and profit across a whole commercial project typically lands between 10% and 20% of hard cost depending on complexity and delivery method. General conditions — the supervision, trailer, dumpsters, temporary power, protection, and cleanup — is a separate 6% to 12% of hard cost and should be presented as a staffed, line-itemed budget, not a percentage plug.

One structural note worth internalizing before you negotiate: none of these ranges are regulated, published, or standardized. There is no schedule a GC must follow. What creates the discipline is competition and transparency, and if a landlord's work letter eliminates both by mandating a single contractor on a lump-sum basis, you have removed the only two forces that keep the number honest.

What drives those numbers

Markup is a function of risk, volume, and information asymmetry. Understand the drivers and you can predict where a given project will land before you ever see a bid.

Project size and absolute dollars. Overhead is largely fixed per project, not per dollar. The same estimator, PM, and superintendent are required for a $150,000 buildout and a $1.5M buildout, so the percentage has to be larger on the small job to cover the same salaries. This is why a small tenant screaming about a 20% material markup is often screaming at arithmetic rather than greed. The productive move on a small job is not to fight the percentage — it is to shrink the base by buying long-lead, high-value items directly.

Occupied versus vacant building. A buildout on a vacant floor in a shell building behaves like light ground-up work: open access, daytime deliveries, freight elevator whenever you want it, material staged on the slab. A buildout on floor 14 of a fully occupied Class A tower means after-hours delivery windows, elevator reservations, protection of finished common areas, noise restrictions, dust partitions, and a superintendent who spends a third of his day on logistics rather than construction. That logistics burden has to live somewhere, and it usually gets folded into the material and general-conditions percentages rather than shown as its own line. Ask for it as its own line — "building logistics" — and the material markup conversation gets much simpler.

Delivery method. Lump-sum (stipulated sum) hides everything: the GC gives you one number, the markup is invisible, and any savings the GC finds during buying-out the job belongs to the GC. Cost-plus with a guaranteed maximum price (GMP) exposes the markup as a stated fee and returns unspent contingency and buyout savings to whoever the contract says gets them. Construction-manager-at-risk sits in between. The number you pay for materials can be identical across all three; what differs is whether you can *see* it and whether savings flow back to you.

Commodity volatility and lead times. When switchgear, rooftop units, or specialty glass carry long lead times, the GC is being asked to hold a price on something they cannot buy for months. They will either price the risk (higher markup or explicit escalation) or push the risk to you (allowance with reconciliation). The second is almost always cheaper and more honest, provided the allowance is realistic rather than a lowball designed to win the bid and generate change orders later.

Who controls the bid list. A GC bidding against two peers prices differently than a GC who knows they are the only option because the lease names them. This is the single largest driver and the one tenants most often surrender in lease negotiation without realizing what they gave away.

Relationship economics between landlord and GC. Landlords who feed a contractor repeat capital work — lobby renovations, restroom upgrades, elevator modernization, spec suites — have leverage that a one-off tenant does not. Sometimes that leverage produces genuinely better pricing for tenants because the GC wants to protect the relationship. Sometimes it produces the opposite: a side arrangement where the GC's TI pricing subsidizes discounted landlord work, or a referral fee flows back to ownership. Both exist. Both are legal when disclosed. Neither is disclosed unless you ask, and the place to ask is during lease negotiation, in writing, with a request that any fee paid by the contractor to the landlord or its affiliates be stated.

Lease, TI allowance, and negotiation levers

Everything meaningful about markup is decided in the work letter — the exhibit to the lease that governs construction — not during construction. Once you have signed a lease that names a contractor, mandates lump-sum pricing, and gives the landlord approval over your drawings, you have almost no leverage left. Here is what to fight for, in rough order of value.

Kill or soften the exclusive GC clause. The strongest position is a free choice of contractor subject to landlord approval "not to be unreasonably withheld," with reasonableness defined: licensed, bonded, carrying stated insurance limits, experienced in comparable buildings. The realistic compromise, and the one most landlords will actually sign, is a bid list of three approved GCs from which you select. Three bidders is not a formality — it is the mechanism that makes every other protection in this list enforceable, because it gives you comparable line items to argue from. If the landlord insists on one contractor, you must extract transparency in exchange, because you have surrendered competition.

Convert to open-book, cost-plus with a GMP. Under open book you receive supplier invoices, subcontractor bids, and the GC's markup shown as a separate stated line. Under a GMP the GC guarantees a ceiling; under a savings-sharing clause, money left over is split (a 50/50 or 75/25 tenant-favorable split is common) or returned entirely to the tenant. Write down where buyout savings go before you sign. A GMP without a savings clause simply converts your money into the GC's margin the moment they buy the job cheaper than they bid it.

Cap overhead and profit as a single number. Rather than negotiating separate percentages for materials, labor, subs, and general conditions — four numbers you will spend a month arguing about — negotiate one combined O&P cap applied to total cost of the work, commonly landing in the 10% to 15% range for commercial TI, and require general conditions to be a detailed staffing-and-equipment budget rather than a percentage. This eliminates the most common abuse in one stroke.

Prohibit compounding. State explicitly that overhead and profit apply to *net* cost — the actual invoiced supplier and subcontractor amounts — and never to a base that already includes markup, contingency, or another fee. Compounding is where a 12% stated markup quietly becomes an effective 22%.

Address the landlord's coordination fee directly. Ask what it covers, whether the same services appear in the GC's general conditions (they frequently do), and convert it from a percentage to a flat dollar amount. A percentage fee on a cost-plus job creates a landlord incentive that runs exactly opposite to yours.

Get the allowance structure right. A tenant improvement allowance can be delivered as landlord-managed work, as a reimbursement against paid invoices, or as a cash contribution. Cash gives you the most control and the lowest effective markup, but landlords resist it and may treat it differently for accounting purposes. Reimbursement is the common middle ground — negotiate for progress reimbursement against lien waivers rather than a single payment at completion, because carrying six months of construction cost is a real financing expense that no one shows you on a spreadsheet. Also negotiate what happens to unused allowance: applied against rent, held for future work, or forfeited. Forfeiture creates an incentive for everyone but you to spend the whole number.

Reserve an audit right. A clause giving you the right to inspect books and records related to the work for a defined period after completion, with the GC bearing audit cost if overbilling above a threshold is found, is cheap to negotiate and changes behavior before anyone exercises it. Pair it with a requirement that all rebates, discounts, and returned material credits accrue to the tenant.

Control change orders in advance. Fix the markup on changes at the same rate as base work — GCs commonly try for a higher rate on changes, which rewards an incomplete original bid. Require written pre-approval above a stated threshold, require pricing backup within a set number of business days, and define what constitutes a legitimate change (scope added by you) versus a coordination failure (something the GC should have caught).

Consider owner-furnished items. Buying high-value, low-risk items directly — light fixtures, appliances, furniture, sometimes flooring or millwork — removes markup entirely on that spend. The trade-offs are real: you assume delivery risk, storage, damage, warranty, and the GC will likely raise installation labor to compensate for lost margin. It works best on items with long lead times you would have to order early anyway, and worst on anything the GC must warranty as a system.

Sequencing the buildout

Timing determines leverage. The tenant who starts thinking about material markup when the first pay application arrives has already lost; the tenant who runs the sequence below routinely lands 5 to 10 points lower on effective material cost, which on a $600,000 buildout is $30,000 to $60,000 of real money.

Start with a test fit and a rough order-of-magnitude budget *before* signing the lease. You cannot evaluate whether a TI allowance is generous until you know what your space actually costs to build, and you cannot negotiate the work letter intelligently without that number. A test fit from an architect is inexpensive relative to a multi-year lease and frequently changes which space you take.

Negotiate the work letter in parallel with the business terms, not after. Once rent, term, and free rent are agreed, the landlord's urgency drops and the work letter gets treated as paperwork. It is not paperwork; it is where a meaningful percentage of your total occupancy cost is decided.

Get drawings to a genuinely biddable level of completeness before soliciting pricing. Bidding off a schematic set guarantees a contingency-loaded number and a change-order-heavy project. The extra weeks of design coordination — especially MEP coordination against the building's existing capacity — pay for themselves several times over.

Bid to three qualified GCs on identical documents with a required bid form that breaks out material, labor, subcontractor, general conditions, and O&P separately. Identical documents and an identical form are what make bids comparable; without them you are comparing three different guesses.

Then level the bids line by line and interview. The lowest number is not the best number if it is achieved by scope gaps, thin allowances, or an aggressive schedule that will generate overtime later. Ask each bidder where they think the drawings are incomplete — the honest answer tells you more about the eventual final cost than the bid total does.

During construction, the discipline is monthly: review each pay application against the schedule of values, require lien waivers from every sub before releasing payment, verify stored-material billings against actual delivery, and log every change order with its own backup. At closeout, reconcile every allowance against actual cost, confirm unused contingency returns to you per the contract, and require credit for returned or unused material at the original unit price rather than a restocking-reduced amount the GC quietly keeps.

One adjacent scenario worth planning for: if you are the party performing work and passing costs *to* a landlord — a build-to-suit, a tenant doing landlord-scope work under a credit, or a franchisee building in a landlord-owned shell — the same mechanics run in reverse and the landlord will apply exactly these audits to you. Price your own overhead and profit as a defensible, documented number rather than a round percentage, keep the books genuinely open, and you will collect more of the credit with less friction than a contractor who resists disclosure.

Related questions

Is the markup different for retail and restaurant buildouts?

Generally higher. Restaurant work involves grease ducts, specialty MEP, health-department inspections, and heavy equipment coordination, so contractors carry more risk and more contingency. Expect the upper end of typical material ranges and a larger escalation allowance on kitchen equipment packages.

Can I buy materials directly and avoid the markup entirely?

On some items, yes. Owner-furnished lighting, furniture, and appliances are common. You absorb delivery, storage, damage, and warranty risk, and the contractor typically raises installation labor to recover lost margin. Get the installation quote in writing before committing.

Does a lower material markup mean a cheaper project?

Not necessarily. A contractor quoting 8% on materials may carry richer general conditions, thinner allowances, or higher change-order rates. Compare total cost of the work with markup shown separately, not the markup percentage alone.

What is the difference between a coordination fee and general conditions?

General conditions is the contractor's cost to run the jobsite — supervision, temporary facilities, cleanup, protection. A coordination fee is paid to the landlord for building oversight. If both charge for the same supervision, you are paying twice; ask for the overlap in writing.

Does the markup change on a lease renewal with refresh work?

Often it improves. Renewal work is smaller, lower risk, and the landlord wants the deal done, so coordination fees get waived and contractors sharpen numbers. Renewal is also the easiest time to insert an audit clause you did not get originally.

FAQ

Is 20% markup on materials unreasonable?

Not automatically. On a small commercial buildout with modest total material spend, 20% may simply reflect fixed overhead spread across a small base. It becomes unreasonable when it is applied to a large material package, when another fee is compounded on top of it, or when there was no competitive bid to test it. Judge the total cost of the work, not the percentage in isolation.

How do I verify a contractor's material pricing is fair?

Request supplier invoices under an open-book arrangement and spot-check commodity items — drywall, studs, ceiling grid and tile, carpet, standard fixtures — against published cost data or a direct quote from a local supplier. For specialty items like custom millwork or MEP equipment, ask the supplier for a quote directly. You do not need to check everything; checking five representative items reliably reveals whether the pricing is honest.

Can the landlord legally require me to use their contractor?

Yes. Exclusive contractor clauses in commercial leases are enforceable in most jurisdictions and are common in institutional buildings. Legality is not the issue — leverage is. Treat the clause as a negotiable business term and, if you cannot remove it, trade your acceptance for open-book pricing, a capped overhead and profit percentage, and an audit right.

What happens to unused tenant improvement allowance?

It depends entirely on the lease. Common outcomes are forfeiture to the landlord, application as a rent credit, or a carry-forward for future work. Forfeiture is the default in many form leases and creates an incentive to spend the entire allowance regardless of need. Negotiate a rent-credit or carry-forward provision before signing.

Should I hire an owner's representative or construction consultant?

On projects above roughly $250,000, usually yes. A competent owner's rep levels bids, reviews pay applications, catches compounded markup and scope gaps, and manages the change-order process. Fees typically run a low single-digit percentage of project cost and are frequently recovered several times over on a first project — plus the knowledge carries into every future lease you sign.

Can I withhold rent over disputed construction charges?

Almost never without an explicit lease provision, and attempting it can trigger default. The correct path is to dispute charges in writing, withhold the disputed portion of the allowance disbursement or final payment rather than rent, preserve all documentation, and involve a construction attorney early if the amount is material.
