A Closer Look at the Costs of Building a New Home

If you're in the market for a new home, you may wonder about the factors contributing to the home's total cost. The National Association of Home Builders (NAHB) recently published a Cost of Construction Survey, which details the various costs of building a typical new single-family home. Many of the results show that the percentage contribution of each component has remained relatively consistent in recent years. 


According to the 2024 survey of home builders, the biggest single component of a new home’s total sales price is construction costs, which accounts for around 64.4%. For example, the sales price of a $665,298 house would likely factor in construction costs of approximately $428,215, or 64.4%.


Survey respondents broke down construction costs into eight major construction stages: 

• Interior finishes (e.g., cabinets, drywall, flooring): 24.1%

• Major system rough-ins (e.g. electrical, HVAC, plumbing): 19.2%

• Framing: 16.6%

• Exterior finishes (e.g., roofing, windows): 13.4%

• Foundations: 10.5%

• Site work (e.g., architecture, building/permit/impact fees): 7.6%

• Final steps (e.g., driveway, landscaping): 6.5%

• Other costs: 2.1%


The share of construction costs to the total price of a new home is the highest since NAHB first produced the survey in 1998. Some of the factors that contribute to the construction costs are the ongoing skilled labor shortages and building material price increases.


The average single-family home size in the 2024 survey was 2,647 sq. ft. of finished floor space, an increase of 86 sq. ft. from 2022. From 2015 to 2022, the average square footage of a home trended downward. Constructing homes with smaller square footage in recent years is a response by builders to meet the current housing affordability challenges buyers face.


Though building practices and the cost of labor, land and materials can vary widely across the country, these national averages provide an overall snapshot for the building industry.

Major EPA Refrigerant Changes Take Effect in 2025

By Jami Clevenger • September 25, 2025
The heating and cooling industry is undergoing a significant transformation as new Environmental Protection Agency regulations take effect to combat climate change. Here's what you need to know about the upcoming refrigerant changes and how they may impact you. What's Changing? Beginning January 1, 2025, manufacturers can no longer produce new HVAC systems using R-410A refrigerant, the most common cooling agent in residential air conditioners and heat pumps. This phase-out is part of the American Innovation and Manufacturing (AIM) Act, which aims to reduce greenhouse gas emissions by transitioning away from high Global Warming Potential (GWP) refrigerants. R-410A has a GWP of 2,088, meaning it contributes significantly to climate change when released into the atmosphere. The new regulations require all refrigerants in new systems to have a GWP of 700 or less. The New Refrigerants Two environmentally friendly alternatives are replacing R-410A: R-454B (Opteon XL41 or Puron Advance): Provides up to a 78% reduction in global warming potential while maintaining similar cooling performance to R-410A. Most major manufacturers including Carrier, Trane, and Lennox have chosen this as their primary replacement. R-32: Offers up to 12% better efficiency than R-410A systems and has a GWP of approximately 675. Daikin and some other manufacturers have selected R-32 for certain applications. Impact on Homeowners If you have an existing system: You can continue using your current HVAC system without any immediate changes required. Existing equipment is not subject to EPA regulations and can continue to be used through equipment end-of-life. R-410A will remain available for servicing existing systems, though supplies may become more expensive over time. If you're buying a new system: Systems manufactured before January 1, 2025, can still be installed through December 31, 2025, giving consumers a one-year transition period. However, new EPA-compliant systems are expected to cost at least 20% more than current models due to advanced technology and manufacturing requirements. Safety Considerations The new refrigerants are classified as A2L, meaning they have low toxicity but are mildly flammable—much less so than propane or natural gas. New systems include advanced leak detection sensors that automatically shut off the unit and activate ventilation if a leak is detected. Benefits of the Transition Beyond environmental protection, the new refrigerants offer several advantages: Potential utility bill savings of 5-10% due to improved energy efficiency EPA estimates this transition will result in emissions reductions equivalent to up to 876 million metric tons of carbon dioxide from 2025 through 2050 Long-term cost savings through reduced energy consumption Planning Ahead While there's no immediate need to replace functioning systems, homeowners should consider their options carefully. If your current system is aging or inefficient, upgrading before 2025 might offer cost savings, while waiting allows you to invest in the latest environmentally friendly technology. HVAC contractors are receiving specialized training to safely handle the new refrigerants, ensuring professional installation and service continue without interruption. For more information about how these changes might affect your specific situation, consult with a qualified HVAC professional who can assess your current system and discuss your options.

What to Know about “No Tax on Overtime” and “No Tax on Tips”

By Jami Clevenger • July 21, 2025
The One Big Beautiful Bill Act (OBBBA) marks progress on two key promises from President Trump’s campaign: eliminating taxes on overtime and on tips. NAHB members may be wondering how these tax changes affect them, whether they’re business owners or employees.
