How do I pass through my own general contractor’s markup to the landlord without losing margin

The Turnkey Allowance Strategy

The single most effective way to pass through your GC's markup without losing margin is to structure the buildout as a turnkey allowance. This means you negotiate a single dollar amount per square foot that covers everything — materials, labor, permits, and your GC's overhead and profit. The landlord sees one clean number, not a breakdown of your GC's fee. Here's how to execute it:

• Get a GMP from your GC first. Before you enter lease negotiations, have your contractor price the entire buildout with their markup included. This becomes your *maximum* cost to present.
• Round up strategically. If the GMP comes to a certain per-square-foot figure, present a slightly higher figure to the landlord. That extra amount is your margin buffer for change orders or scope creep — and it's invisible to the landlord.
• Frame it as a "fixed-price buildout package." Landlords love certainty. A turnkey allowance eliminates their risk of cost overruns, so they're often willing to pay a premium for it. Use language like "turnkey TI allowance" or "fully loaded buildout cost" in the lease.
• Never itemize the GC's fee. The moment you show a line for "general contractor fee," the landlord will demand to cut it or replace your GC with theirs. Keep the fee buried in the unit price.

This strategy works best when the TI allowance is not capped by the landlord's standard offer. If they offer a certain per-square-foot amount and your turnkey cost is higher, you need to negotiate the difference as additional TI or a rent abatement to cover the gap.

The Management Fee Loophole

If the landlord insists on a cost-plus or open-book structure — where they see every subcontractor invoice and your GC's actual costs — you need a different mechanism. Enter the management fee. This is a separate fee your GC charges for overseeing the project, typically a percentage of hard costs, and it's standard in the industry. Here's the play:

• Negotiate the management fee into the TI allowance as a separate line item. Frame it as "project management and coordination fee" — landlords accept this because it's a standard cost in any construction project.
• Keep the GC's profit separate. The management fee covers *overhead* (scheduling, supervision, admin). The GC's profit markup gets buried in the subcontractor pricing or material markups.
• Use a "cost-plus with a guaranteed maximum" structure. This gives the landlord transparency on hard costs while protecting your margin. The GC's fee is a fixed percentage, but the total is capped — so if costs come in under budget, the GC (and you) keep the savings.
• Example presented includes all. The landlord sees the management fee as legitimate overhead; the profit is hidden in the hard cost estimates.

This loophole works because management fees are standard in commercial construction and landlords' own project managers charge similar fees. It's not suspicious — it's expected.

The Hard Cap Negotiation Tactic

The hard cap is your best friend when passing through GC markup. A hard cap means the landlord agrees to pay a fixed amount for the buildout, and any cost overruns are your responsibility — but so are any savings. Here's how to use it to protect your margin:

• Set the cap above your true cost. If your GC's all-in price is a certain amount, negotiate a hard cap that is higher. That cushion covers your GC's markup and gives you room for change orders without eating into your margin.
• Use "change order contingency" language. Frame the extra amount as a contingency fund (typically a percentage of the buildout cost). Landlords accept this as prudent project management. Your GC's markup is hidden in that contingency.
• Negotiate a "shared savings" clause. If the project comes in under the hard cap, you split the savings with the landlord. This incentivizes the landlord to approve a higher cap because they might get money back. Meanwhile, your GC's markup is already baked into the base cost.
• Avoid a "cost-plus with no cap" structure. That's where landlords scrutinize every line item and demand to see your GC's actual costs. A hard cap gives you control.

The hard cap works especially well in competitive lease markets where landlords want to close quickly. They'd rather agree to a fixed number than haggle over every subcontractor bid.

The Subcontractor Markup Strategy

If the landlord demands open-book pricing, you can still protect your GC's margin by embedding it in subcontractor pricing. This is a common practice in commercial construction and hard for landlords to detect without deep market knowledge:

• Have your GC mark up subcontractor bids before presenting them. For example, if a subcontractor bids a certain amount, your GC adds a percentage to make it a higher figure. The landlord sees a single subcontractor number; the markup is invisible.
• Use "material handling fees." Your GC charges a fee on all materials for procurement and delivery. This is standard and accepted. It adds to the GC's margin without looking like a profit line.
• Bundle small trades into larger packages. Instead of separate bids for flooring, painting, and millwork, have your GC combine them into one "finishes package" with a single price. The markup is spread across the bundle and harder to audit.
• Add "permitting and expediting fees." These are legitimate costs that can be padded slightly. Landlords rarely question them.

This strategy requires your GC to be on board and discreet. You need a contractor who understands the commercial lease game and is willing to play ball. If your GC is a small residential guy, they might not get it — hire a commercial GC with experience in tenant buildouts.

The Landlord's Own GC Trap

Many landlords will try to force you to use their preferred GC or their in-house construction team. This is a trap — their GC will charge a markup, and you'll have zero control over costs or quality. If you want to pass through *your own* GC's markup, you must avoid this trap:

• Negotiate the right to use your own GC in the lease. This is non-negotiable for you. If the landlord insists, frame it as "tenant's right to select contractor" and tie it to the TI allowance. Landlords often concede if you agree to a hard cap on the allowance.
• If forced to use their GC, demand a "tenant's representative" fee. You can hire your own project manager to oversee the landlord's GC. That fee is passed through as part of the TI allowance. It's not your GC's markup, but it protects your interests.
• Use a "stipulated sum" contract with the landlord's GC. This means the landlord's GC gives you a fixed price for the buildout, and you negotiate that price down. Your own GC's markup is irrelevant here — you're just negotiating the final number.
• Worst case: take the TI allowance as cash. Some landlords will give you the TI allowance as a cash contribution lump sum and let you manage the buildout yourself. This is the cleanest way to pass through your GC's markup — you hire your own GC, pay them, and keep any savings.

The trap is real: landlords' GCs often charge significant markup and use their own subcontractors at inflated rates. You're better off with your own GC even if you have to fight for it.

The Timing and Documentation Play

The timing of when you reveal your GC's involvement matters enormously. Here's the sequence that protects your margin:

• Step 1: Negotiate the TI allowance first. Before you mention your GC, get the landlord to agree to a TI allowance per square foot. This is the pot of money.
• Step 2: Bring in your GC after the allowance is set. Now you have a budget to work with. Your GC prices the buildout to fit within that allowance, including their markup.
• Step 3: Present the GC as a "tenant's contractor" after lease execution. Don't introduce them during lease negotiations — that gives the landlord time to object. Once the lease is signed, you have the right to manage the buildout.
• Step 4: Document everything in the lease. The lease should state: "Tenant shall have the right to select and manage its own contractor for the buildout, subject to landlord's reasonable approval." This gives you legal cover.

Documentation is your shield. Keep all GC invoices, bids, and contracts in a tidy file. If the landlord audits, you can show that the total cost matches the allowance. Never show the GC's internal markup breakdown — that's proprietary.

The Change Order Leverage

Change orders are where you can recover margin if the initial allowance was too tight. Here's how to use them:

• Build a "change order contingency" into the allowance. As mentioned, a percentage of the TI allowance should be labeled as contingency. When change orders come (and they will), your GC's markup is applied to the change order cost — and that markup is passed through as part of the change order price.
• Scope creep in your favor. If you can add scope that the landlord wants (e.g., upgraded flooring, additional outlets), the change order includes your GC's markup. The landlord pays for the upgrade *plus* the markup.
• Never absorb change order costs. If the landlord requests a change, insist it's a tenant improvement allowance addendum — they pay the full cost including your GC's fee. Frame it as "the contractor's overhead is already allocated; any change requires re-mobilization."
• Use "time and materials" for change orders. This is a higher-margin structure that includes your GC's full markup. Landlords accept this for small changes because it's simpler than re-bidding.

The change order game works best when the landlord is under time pressure to open the space. They'll approve markups they'd otherwise reject just to keep the project moving.

FAQ

What is a typical general contractor markup for commercial buildouts? A standard general contractor markup varies depending on project complexity and market conditions. This includes overhead (insurance, office, supervision) and profit. Markups are typically expressed as a percentage of hard costs.

Can I just add my GC's markup to the TI allowance as a separate line item? No, that's the fastest way to get rejected. Landlords see a separate "GC fee" as double-dipping because they already include construction management in their own costs. Always embed the markup into the total price.

What if the landlord demands to see my GC's actual costs? You can refuse politely by citing proprietary pricing agreements with your subcontractors. If they insist, use the management fee loophole or switch to a hard cap structure where costs are irrelevant.

Do I need a lawyer to write these lease clauses? Yes, absolutely. A commercial real estate attorney experienced in tenant buildouts can draft the "tenant's right to select contractor" clause and ensure the TI allowance language protects your margin. This is not a DIY job.

How do I handle a landlord who wants to use their own GC? Negotiate for a cash TI allowance instead of a buildout. If they refuse, demand a tenant's representative fee to oversee their GC. Worst case, walk away — their GC will eat your margin.

What's the biggest mistake tenants make with GC markup? Showing the base cost to the landlord. Once they see your GC's actual costs, they'll try to cut the markup. Always present the all-in price as the only number that matters.
