Planning a renovation, home addition, or commercial buildout in 2026? You may have noticed that construction estimates are changing faster than expected. Material tariffs, supply chain pressure, and the Federal Reserve’s September rate hike are all affecting project budgets.
That does not mean you need to put your plans on hold. It does mean that a clear scope, realistic allowance, and reliable project communication matter more than ever.
At Farris General Contracting, we help homeowners, developers, and business owners understand where costs come from and how to plan for them. Here is what to know before moving forward with your project.
Why construction material costs are under pressure
Tariffs do not affect every product in the same way. The final impact depends on the material, country of origin, product classification, supplier, and whether the material is already in stock. Still, several categories commonly used in home renovations and commercial construction are facing added cost pressure.
Lumber and plywood
Lumber is used throughout framing, roofing, flooring, cabinetry, and other parts of a renovation. Plywood is especially important for subfloors, sheathing, cabinets, and structural applications.
Industry reporting indicates that softwood lumber costs are up in 2026, with duties and trade measures affecting imported materials. Plywood and other wood products may also be exposed to additional tariffs depending on where they are manufactured and how they enter the country.
For a homeowner, this can affect everything from a small kitchen remodel to a second-story addition. For a commercial client, the impact can multiply across framing packages, tenant improvements, and multi-unit projects.
Steel and metal products
Steel is used in structural framing, rebar, metal studs, fasteners, doors, equipment, and many specialty products. Tariffs on steel and steel-based products can increase both the direct material cost and the cost of fabrication and delivery.
Even projects that do not use large structural beams may be affected by metal price increases. A commercial buildout, for example, may include metal framing, electrical components, HVAC supports, and fire protection materials.
HVAC components
Heating and cooling equipment includes compressors, coils, controls, electrical parts, and other components sourced through complex international supply chains. Reports in 2026 have pointed to HVAC price increases in the mid-teens or higher for some equipment categories.
This matters during basement finishes, whole-home renovations, additions, and commercial projects where a new mechanical system or larger capacity unit is required. Longer lead times can also create scheduling concerns if equipment is not selected early.
Cement and concrete
Concrete pricing is influenced by local supply, fuel, labor, transportation, and regional demand. Certain imported cement products may also be affected by tariffs.
The cost impact can be significant for foundation work, garage additions, structural repairs, site work, and commercial foundations. Concrete is often ordered at a specific stage of the project, so delays or price changes can affect the schedule quickly.
How the September Federal Reserve rate hike affects project planning
On September 16, 2026, the Federal Reserve raised its benchmark interest rate by 0.25 percentage points, bringing the target range to 3.75%–4.00%.
The rate change does not automatically increase the cost of every loan. However, it can affect financing options commonly used for construction and remodeling, including:
- Home equity lines of credit
- Variable-rate construction loans
- Personal renovation loans
- Commercial construction financing
- Revolving credit used by property owners and developers
For homeowners, this may increase the cost of borrowing for a renovation or house addition. For commercial clients, higher short-term borrowing costs can change a project’s cash flow or return-on-investment calculation.
The practical lesson is simple: estimate both the construction cost and the financing cost. A project that fits your material budget may still need adjustment if the monthly payment or interest expense is higher than expected.
How to create a more realistic 2026 renovation budget
1. Start with a clear project scope
The more defined your project is, the more useful your estimate will be. Before requesting a final proposal, identify:
- Which rooms or areas are included
- The desired layout and structural changes
- Finish levels and material preferences
- Appliances, fixtures, and equipment
- Permit or design requirements
- Your preferred start and completion window
A vague scope makes it difficult to compare bids. It can also lead to changes later, when material prices or availability may be different.
If you are planning a kitchen remodel, for example, decide whether the project includes cabinetry, countertops, flooring, lighting, plumbing changes, and appliance installation. For a house addition, clarify whether the estimate should include foundation work, roofing, exterior matching, and utility upgrades.
You can explore Farris General Contracting’s remodeling services and custom addition services to see how these project categories are typically approached.
2. Separate allowances from fixed selections
An allowance is a budget amount set aside for an item that has not been selected yet. Cabinets, tile, flooring, plumbing fixtures, appliances, and lighting are common examples.
Ask your contractor which parts of the estimate are based on allowances and which parts are based on current supplier pricing. If an allowance is too low for your preferred finish level, the budget may increase during construction.
Early selections can help reduce this uncertainty. They also give your contractor more time to check availability, compare suppliers, and identify potential substitutions.
3. Ask how long pricing is valid
Material quotes are not always valid indefinitely. Ask whether the estimate includes:
- A quote expiration date
- Supplier price holds
- Freight or delivery charges
- Tariff-related surcharges
- Escalation provisions
- Substitution procedures if an item becomes unavailable
A responsible general contractor should explain these terms before work begins. You should not have to guess why a material cost changed.
4. Consider locking in key materials early
It may make sense to order or reserve certain materials before construction begins, especially when they have long lead times or volatile pricing.
This could include:
- HVAC equipment
- Windows and exterior doors
- Structural steel
- Specialty lumber or plywood
- Electrical equipment
- Custom cabinetry
- Plumbing fixtures with limited availability
Early purchasing is not always the right answer. Storage, deposits, warranty timing, and design changes must be considered. Your contractor can help determine which items are worth securing and which should be purchased closer to installation.
5. Build in a reasonable contingency
A contingency is not extra money for unnecessary upgrades. It is a reserve for conditions that cannot be fully known before demolition or construction begins.
For many renovation projects, a contingency of approximately 10%–20% may be appropriate, depending on the age of the property, the amount of structural work, and how complete the design is. Older homes and projects involving foundations, plumbing, electrical systems, or hidden conditions may require more flexibility.
Your contractor should help you understand what the contingency is intended to cover. It may include concealed damage, required code updates, design changes, or material substitutions. It should not be used as a substitute for a complete estimate.
What the Housing Tariff Exclusion Act could mean
The Housing Tariff Exclusion Act, H.R. 10416, was introduced in the U.S. House on September 16, 2026. The bill would establish a process for excluding certain home-construction products from specified tariffs when those products are critical or not available in sufficient quantities from domestic sources.
The National Association of Home Builders, or NAHB, supports the legislation. The organization says the bill could provide relief for builders and remodelers by creating a faster review process for commonly used homebuilding products.
However, the bill is only a proposal at this stage. It has not eliminated current tariffs or changed the cost of materials for projects being planned today. Homeowners and commercial clients should build their budgets using current pricing rather than assuming future tariff relief will arrive in time.
You can review the official text of H.R. 10416 and read NAHB’s summary of the legislation.
How Farris General Contracting helps you avoid surprises
Volatile pricing makes communication especially important. At Farris General Contracting, we begin by discussing your goals, budget, timing, and material preferences. We then help organize the project around a clear scope and practical selections.
Our process includes:
- Reviewing the project goals and existing conditions
- Identifying materials that may have longer lead times
- Discussing allowances and contingency planning
- Coordinating with suppliers and trade partners
- Providing updates as the work progresses
- Explaining changes before they affect the budget
- Managing the project through completion
Whether you are planning home renovations, house additions, or commercial improvements, you deserve a residential contractor or general contractor who keeps you informed. Clear communication cannot eliminate market changes, but it can help you make decisions before those changes become expensive surprises.
Plan your project with current information
Material tariffs and interest rates may continue to change throughout 2026. Waiting for perfect market conditions is not always practical, especially when a renovation addresses comfort, safety, business needs, or a growing household.
Instead, focus on what you can control:
- Define the scope.
- Compare realistic material options.
- Confirm quote expiration dates.
- Reserve key materials when appropriate.
- Include a contingency.
- Review financing costs.
- Choose a contractor who communicates clearly.
