Construction costs in 2026 are not just rising — they are restructuring the economics of every new development deal in commercial real estate, and doing so in ways that are simultaneously punishing for sponsors trying to build and powerfully beneficial for sponsors who already own. JLL’s mid-year construction update, published July 7, 2026, is the clearest and most current picture of what is actually happening on the ground: final-cost indices are running approximately 5% year-over-year with further acceleration expected in the second half of 2026. Steel, aluminum, and imported metal furniture now face tariff rates of up to 50%. Construction employment growth is tracking at just 0.6% against a historical average of 2.7%. And 61% of U.S. metro markets are currently supply-constrained for construction labor — a figure JLL expects to rise to 72% by 2027. For sponsors financing new projects, this is the most challenging cost environment since 2022. For sponsors who own existing assets, it is the most powerful replacement cost advantage in a decade.

The Three Cost Drivers — and Why Rate Cuts Won’t Fix Them

The most important insight in JLL’s July 2026 mid-year construction report is not the specific cost numbers — it is the structural conclusion about why rate relief will not solve the problem. Interest rate reductions, while a positive driver for the industry, do not change the underlying material price escalation or labor challenges caused by trade and immigration policies. Trade and labor costs will compound faster than anticipated interest rate relief, leading to a net increase in costs in 2026.

That is a significant departure from the conventional developer’s playbook of the past three years, which has been: hold on, wait for rate cuts, then build. In 2026, the calculus has changed. Even if the Fed delivers 75 basis points of cuts over the next 12 months, JLL’s analysis suggests construction costs will have risen by more than that relief provides in debt service savings. The net effect for development economics is that the rate environment is necessary but no longer sufficient — and for some project types in some markets, it may not be sufficient at any rate level.

The Tariff Timeline: Where Costs Have Landed

While policy remains in flux, Cushman & Wakefield estimates that current tariff rates as of April 7, 2026, will result in an increase to construction materials costs of 6.0% relative to a 2024 baseline and total project costs are estimated to rise 3.0%. When tariff rates were at a peak in summer 2025, the estimate was materials costs up 9.0%, so recent developments are encouraging but do not mitigate cost risk completely.

The categories absorbing the heaviest tariff impact are not uniformly distributed across property types — and that creates meaningful underwriting differentiation by asset class.

Trade policy remains fluid. USMCA revisions are expected in 2026, which may provide greater clarity on North American trade, but uncertainty persists around trade policy more broadly, particularly with important trading partners such as China. Ongoing monitoring of trade policy, import data, and material pricing is not optional — it is essential for identifying when cost pressures shift from manageable to deal-breaking.

The Labor Crisis Is Structural — Not Cyclical

The materials story gets most of the attention. The labor story is more consequential.

Construction employment growth is tracking at only 0.6% in 2026, well below the historical average of 2.7%. Geographic mismatches intensify pressure, with 61% of U.S. metro markets currently supply-constrained, a figure anticipated to rise to 72% by 2027. Because construction workers cannot easily relocate to fill labor gaps in other regions, these shortages are structural rather than temporary.

The National Center for Construction Education and Research projects roughly 41% of the current construction workforce will retire by 2031, a compressed timeline that training pipelines are not equipped to absorb. Apprenticeship programs typically require five to seven years to produce fully credentialed workers.

The immigration enforcement dimension adds another layer of immediacy. Aggressive immigration enforcement has created immediate disruptions in major markets that will have lasting negative effects on industry capacity. Currently, workforce-related disruptions are partially masked by limited activity but will be acutely noticeable when demand accelerates. Sponsors planning 2027 and 2028 projects need to account for labor constraints that will be materially worse than what they are bidding against today — not better.

Who Wins and Who Loses in This Environment

The cost escalation story has a clear set of winners and losers — and they are not distributed by property type. They are distributed by position in the capital stack and the timing of construction relative to the cost cycle.

The Financing Implications: What This Means for Debt Sizing

Rising construction costs change the debt conversation in several ways that are directly relevant to how HB Capital structures financing for development and value-add clients.

Hard cost contingency is no longer optional. The standard 5–7% contingency that was adequate for 2021 and 2022 projects is insufficient in a 2026 environment where tariff policy can change quarterly, labor costs are structurally rising, and H2 acceleration is the base case. Lenders underwriting construction loans in mid-2026 are requiring 10–12% contingency for projects in high-exposure markets, and sponsors who have not budgeted accordingly are finding that their equity stack comes up short when they reach financial close.

GMP contracts and early procurement have become credit events. A project with a guaranteed maximum price contract and pre-procured steel and aluminum is, from a construction lender’s perspective, a fundamentally different credit than an open-book cost-plus project in a tariff-volatile environment. Sponsors who have done the work to lock cost certainty early are finding that this gives them a meaningful advantage in both lender appetite and pricing.

Replacement cost underwriting is shifting acquisition financing. Because construction costs are rising faster than cap rates are compressing, the gap between acquisition cost and replacement cost is widening for many existing asset types. This means acquisition lenders have more collateral coverage than the income-based underwriting alone suggests — and in some cases, replacement cost basis is becoming the binding constraint that determines maximum loan amount rather than debt service coverage.

What HB Capital Is Watching

• 1Cost contingency requirements in construction loan underwriting. We are actively working with clients to right-size contingency in their project budgets before they engage lenders — because a deal that comes to market with inadequate contingency burns time and credibility when the lender requires a resubmission. In mid-2026, 10–12% contingency is the baseline for tariff-exposed markets.
• 2GMP contract status as a lender-facing competitive advantage. Sponsors who can demonstrate that their major subcontractor agreements are at a fixed price with limited escalation clauses are closing construction loans faster and at better terms than sponsors with open-book arrangements. If you are pre-development, this is the single highest-leverage step you can take before going to market for debt.
• 3Replacement cost gap as the underwriting frame for existing asset acquisitions. For value-add and stabilized acquisition deals, we are building the replacement cost analysis into the lender presentation alongside the income-based underwriting. In markets where replacement cost exceeds acquisition price by 20–30%, this provides meaningful protection that sophisticated lenders will recognize and price into their credit decisions.
• 4Labor market mapping before site selection. In a world where 61% of markets are already supply-constrained for construction labor — rising to 72% by 2027 — the labor availability in a specific submarket is now a genuine site selection criterion, not an afterthought. We are advising development clients to research labor market depth and proximity to trade school and apprenticeship programs as part of their pre-development diligence, alongside the traditional site and entitlement analysis.

Executive Takeaway

Construction cost escalation in 2026 is not a temporary problem waiting for rate relief — it is a structural condition driven by tariff policy, demographic labor constraints, and the data center boom’s consumption of shared trade capacity. JLL’s conclusion is direct: even with rate cuts, net construction costs will rise in 2026 because trade and labor headwinds outpace interest rate relief.

For sponsors developing new projects, the imperative is clear: lock cost certainty early, right-size contingency now rather than after lender review, and choose markets where labor availability is a feature rather than a constraint. For sponsors who own existing assets, this environment is working in their favor every day that a competing development project gets shelved or delayed. The 41% surge in project abandonments in late 2025 is not a warning signal for existing owners — it is a competitive moat widening in real time.

HB Capital finances both sides of this equation — development projects that have done the work to achieve cost certainty, and acquisitions of existing assets where rising replacement costs are creating a compelling floor under value. In both cases, the quality of the underwriting and the structure of the debt stack are what determine whether rising construction costs are a threat or a tailwind.
