How do I calculate the true cost of using the landlord’s preferred GC versus my own

📖 2,254 words🗓️ Published Jul 2, 2026

Direct Answer

The true cost of using the landlord’s preferred general contractor (GC) is never just the line-item bid — it’s the sum of inflated overhead, lost control over subcontractor quality, and hidden change-order fees that can quietly add a meaningful premium to your buildout budget compared to a competitive market bid. Landlords push their preferred GC because that contractor knows the building’s quirks, has existing insurance and lien waivers in place, and often has a longstanding relationship with the landlord that can streamline coordination. On the other hand, bringing your own GC means you must cover additional general liability insurance, builder’s risk coverage, and performance bonds that the landlord’s GC already carries — and you’ll face strict scheduling windows that can trigger liquidated damages if your GC misses deadlines. The real calculation is a three-column spreadsheet: column one is the landlord GC’s total bid plus estimated change-order risk (add a reasonable contingency for unknowns), column two is your GC’s bid plus insurance and bond costs (typically an extra amount per square foot), and column three is the soft-cost difference — the landlord’s GC saves you time in permitting and coordination, which at typical market rents on a commercial space equals real rent abatement value. Run that math before you sign the work letter or tenant improvement agreement, and always demand the right to bid the work among three GCs — including one of your own choosing — with the landlord obligated to accept the lowest qualified bid.

The Landlord’s GC Incentive Structure

Landlords don’t recommend a GC out of kindness — they recommend one because it reduces their risk and often adds to their bottom line. The typical arrangement: the landlord’s preferred GC has a pre-existing relationship with the landlord, often built over multiple projects in the same building. That relationship means the GC is already pre-approved for the building’s insurance requirements, has existing lien waivers on file, and knows the building’s structural quirks — like where the main electrical riser is or which elevator can handle drywall deliveries. This familiarity means the landlord’s GC can start faster and avoid coordination delays, but it also means they have less incentive to bid competitively because they know they’re the only game in town. The true cost includes not just the higher bid but the lost opportunity of not getting competitive pricing from three independent bidders. Always ask the landlord: *“What is your relationship with this GC? Do you receive any fee or benefit from their selection?”* In many jurisdictions, commercial lease law requires disclosure of such arrangements — and even where it doesn’t, asking puts the landlord on notice that you’re watching.

The Three-Column Cost Model

The three-column model is your decision tool. Column 1 starts with the landlord’s GC’s written bid — the base contract price plus any allowances for finishes, fixtures, and equipment. To that, add a reasonable change-order contingency because the landlord’s GC often lowballs the initial bid knowing they’ll make profit on change orders. Column 2 is your own GC’s bid, but you must add the costs your GC doesn’t carry: additional insured endorsement to the landlord’s policy, a builder’s risk policy, and possibly a performance bond if required. Also add coordination fees — the landlord may charge a project management fee if you use an outside GC. Column 3 calculates the schedule value: if the landlord’s GC can start sooner versus your GC needing more time for approvals, that delay costs you rent you’d otherwise be paying during buildout. At typical market rents on a commercial space, that delay can represent a significant dollar amount in lost rent abatement value. The true cost is the lowest total of all three columns combined.

Hidden Costs in the Work Letter

The work letter — that section of your lease that defines the tenant improvement (TI) allowance and buildout process — is where hidden costs live. Landlords often write the work letter to favor their preferred GC in subtle but expensive ways. Watch for these clauses:

“GC must be pre-approved by landlord, approval not to be unreasonably withheld.” That sounds fair, but the landlord can delay approval for weeks, burning your schedule. A better clause: *“Landlord shall approve or reject tenant’s proposed GC within five business days.”*
“All work must be performed during building standard hours.” Your GC may need overtime or weekend work to meet your deadline — and the landlord’s GC typically has pre-arranged access while your GC pays a premium. That adds significant cost to labor.
“Tenant shall pay for all building standard upgrades.” The landlord’s GC knows exactly what “building standard” means — your GC will need to spend money on consultant fees just to figure it out.
“Landlord reserves the right to charge a coordination fee.” That fee — often a percentage of contract value — is commonly waived for the landlord’s GC but charged to yours. On a typical buildout, that can be a substantial extra cost.

The fix: redline the work letter before you sign. Demand that any coordination fee be waived if you use a qualified, insured GC. Require that overtime be allowed at no extra charge if the landlord’s GC gets the same privilege. And insist on a hard cap on the landlord’s approval timeline.

Insurance and Bonding: The Real Cost of Independence

Bringing your own GC means you must bridge the insurance gap between your contractor’s coverage and what the landlord requires. The landlord’s preferred GC already has sufficient general liability, umbrella coverage, and workers’ compensation that meets the building’s minimums — and the landlord trusts those policies because they’ve seen them. Your GC will need to add the landlord as an additional insured, provide a certificate of insurance naming the landlord, and often secure a builder’s risk policy that covers the building during construction. These costs are real:

Additional insured endorsement: A one-time fee from the insurance carrier.
Builder’s risk insurance: A percentage of contract value.
Performance bond (if required): A percentage of contract value.
General liability upgrade: If your GC’s policy has lower limits, they must buy a difference-in-limits policy.

Total added cost can be a meaningful percentage of your budget before you even break ground. Compare that to the landlord’s GC, which carries all that already — but remember, the landlord’s GC bakes their insurance costs into their overhead, so you’re paying for it either way. The question is whether you’re paying a fair market rate or a monopoly premium.

Schedule Value and Rent Abatement Math

The schedule is the most overlooked cost in the GC decision. Landlords typically offer rent abatement during the buildout period — often several months of free rent while you construct. If your GC takes longer but the landlord’s GC could do it faster, that extra month of rent abatement is pure value you lose. Here’s the math:

Space: A typical commercial space
Annual rent: Market rate per square foot
Monthly rent: Calculated from annual figure
Rent abatement period: Shorter with landlord’s GC, longer with your GC
Value of extra month abatement: Real dollar savings

But wait — there’s a catch. Many landlords cap the rent abatement at a fixed dollar amount. If the landlord’s GC finishes faster, you use less of that cap, leaving unused abatement — which you can often convert to additional TI allowance. Your GC taking longer burns the full cap. So the true schedule cost is the difference in abatement used plus the lost opportunity to convert unused abatement to TI dollars. Always ask: *“Is the rent abatement a fixed period or a fixed dollar amount?”* If it’s fixed dollars, the faster GC wins even more.

Negotiating the Right to Bid

You don’t have to accept the landlord’s GC as a fait accompli. Negotiate the right to bid the work among at least three qualified contractors — one of whom is the landlord’s preferred GC, and at least one of whom you select. The lease clause should read: *“Tenant shall have the right to obtain bids from three qualified, licensed, and insured general contractors. Landlord shall accept the lowest qualified bid, provided such bid is within a reasonable percentage of the landlord’s preferred GC’s bid.”* This gives you competitive pricing while protecting the landlord from a rogue lowball bid that skimps on quality. If the landlord resists, remind them that most commercial leases in competitive markets already include this right — and that a transparent bidding process reduces disputes later. If you can’t get the right to bid, at least negotiate a hard cap on the landlord’s GC’s overhead and profit — a fair percentage of direct costs is reasonable. Anything significantly above that is a red flag.

Hidden Cost: Schedule Compression and Overtime Premiums

The landlord’s preferred GC often works under a pre-negotiated timeline that prioritizes the landlord’s leasing schedule over your buildout quality. This can force your subcontractors into overtime or weekend work to meet tight deadlines, adding a meaningful premium to labor costs that may not appear in the base bid. Conversely, your own GC can negotiate a more realistic schedule that avoids premium labor rates, but only if the landlord allows sufficient access and doesn’t impose liquidated damages for delays. To compare accurately, ask both GCs for a schedule with estimated overtime costs baked in—then factor in the risk of rush fees for materials, which can spike if the landlord’s GC orders from their preferred suppliers at premium prices.

Soft-Cost Trap: Lost Rent Abatement and Tenant Improvement Allowance

The true cost also includes how the landlord structures your tenant improvement (TI) allowance. If you use the landlord’s preferred GC, the allowance often covers more of the base build—meaning you keep more of your TI budget for finishes or upgrades. With your own GC, the landlord may deduct a coordination fee or require you to pay for building-specific compliance items (e.g., sprinkler system tie-ins, elevator protection) that the preferred GC would have included. Calculate the net TI allowance after these deductions, then compare it to the total buildout cost. A lower bid from your GC can be wiped out if the landlord claws back thousands in allowance for items they consider “non-standard” with an outside contractor.

FAQ

What if the landlord insists their GC is the only one allowed? Then you need to price that monopoly into your lease negotiation. Ask for a higher TI allowance to offset the expected higher costs, or demand a guaranteed maximum price (GMP) contract from the landlord’s GC with a shared savings clause — if the GC comes in under budget, you split the savings.

How do I know if the landlord’s GC’s bid is inflated? Get a third-party cost estimate from a construction consultant or an independent estimator. For a reasonable fee, they’ll give you a line-item breakdown of fair market prices for your market. If the landlord’s GC is significantly above that estimate, you have leverage.

Can I hire my own GC for just the finish work? Sometimes. Many landlords allow you to use your own GC for non-structural, cosmetic work (painting, flooring, millwork) while the landlord’s GC handles core and shell work. This hybrid approach can save you money on the finish portion while keeping the landlord comfortable.

What about union vs. non-union GCs? In union-heavy markets like New York, Chicago, or San Francisco, the landlord’s GC is almost always union-signatory. Your non-union GC may face jurisdictional disputes or slowdowns that add time to the schedule. Factor that risk into your decision — sometimes the union GC is worth the premium.

Does the landlord’s GC affect my TI allowance? Yes. Most TI allowances are paid directly to the GC, not to you. If you use your own GC, the landlord may hold back a percentage of the allowance as a retainage until the work passes inspection. The landlord’s GC often gets no retainage or a lower percentage. Negotiate for equal treatment on retainage terms.

What if my GC goes over budget? That’s your problem — not the landlord’s. The lease’s work letter typically states that any cost overruns are the tenant’s responsibility. That’s true whether you use the landlord’s GC or your own. The difference: the landlord’s GC has more incentive to stay on budget because they want future work from the landlord. Your GC has less of that incentive.
