2025–2026 Tariff Alert — Construction Costs Are Up
Steel (+25%), Canadian lumber (+14.5%), aluminum (+10%), and Chinese-made HVAC & electrical components are all subject to active US tariffs. The average 2,000 sq ft home now costs $28,000–$47,000 more to build than pre-tariff 2024 pricing. Use this calculator to see your exact exposure.

How 2025–2026 Tariffs Are Affecting Home Construction
🪵
Lumber: Canadian softwood tariffs at 14.5%
The US Commerce Department raised duties on Canadian softwood lumber — which supplies ~30% of US framing lumber — to 14.5% in 2025. Framing, sheathing, and engineered wood products are all affected. This is the single largest tariff impact on residential construction.
🔩
Steel: Section 232 tariffs at 25%
Steel tariffs remain at 25% for most imports. This affects rebar, structural steel, metal framing studs, roofing panels, and garage doors. Homes with steel framing or concrete reinforcement (particularly in Texas, Florida, and hurricane zones) see the highest steel cost impact.
🪟
Aluminum: 10% tariff hitting windows and doors
Aluminum tariffs at 10% flow directly into window frames, door frames, sliding patio doors, and decorative elements. Premium window packages (Anderson, Pella, Marvin) have passed through most of these costs with price increases announced in late 2024 and early 2025.
❄️
HVAC: Chinese component tariffs up to 145%
HVAC equipment with significant Chinese component content faces steep import duties. Refrigerant pricing has also surged due to phasedown schedules and tariff overlap. Budget systems are more exposed than premium US-made equipment from Carrier, Trane, or Lennox.
⚡
Electrical: Wiring and panels affected
Chinese-made electrical panels, wiring devices, and conduit materials face elevated duties. Copper wire pricing has also been volatile due to global demand. Electricians report 15–25% increases in rough-in material costs compared to 2023.
Frequently Asked Questions
How much are 2026 tariffs adding to the average new home?
For a typical 2,000 sq ft standard-finish home, current tariffs are adding approximately $28,000–$47,000 to construction costs compared to 2024 pre-tariff pricing. The range depends on your state, finish level, and how much steel vs wood framing your build uses.
Which construction materials are most affected by tariffs?
Steel (25% tariff via Section 232) and Canadian lumber (14.5%) have the largest dollar impact on home construction. HVAC equipment with Chinese components faces the highest percentage tariff — up to 145% on some products — but represents a smaller share of total build cost.
Will tariffs go down before I build?
This is uncertain. Lumber tariffs have fluctuated historically based on US-Canada trade negotiations. Steel tariffs have been in place since 2018 and show no signs of removal. Most construction economists expect elevated material costs to persist through at least mid-2027.
Can I lock in material prices now to avoid tariff increases?
Yes — many lumber yards and steel suppliers offer forward contracts or price locks for 60–90 days. If you are planning a build in 2026, locking in framing packages and steel early can provide meaningful savings. Ask your GC or supplier about escalation clause protection in your contract.
Are tariff costs included in contractor quotes?
Most GCs and contractors updated their pricing through 2025 to include current tariff-adjusted material costs. However, contracts signed in 2024 may have escalation clauses that allow contractors to pass through material cost increases. Always ask what material escalation protections exist in any fixed-price contract.
How accurate is this tariff calculator?
This calculator uses publicly documented tariff rates applied to 2026 RSMeans material cost baselines, adjusted by state multiplier. It is designed to give directional accuracy within ±20%. Your actual tariff exposure depends on your specific subcontractors, their supply chains, and project scope. Use this as a planning tool, not a guarantee.
