Energy Mandates and Affordable Housing: The Hidden Costs of Regulation

The Hidden Costs of Mandates: Why Energy “Choice” is Critical for Affordable Housing

Energy mandates and affordable housing are directly connected, shaping one of America's most pressing crises. Home prices and rents are rising faster than incomes. New housing supply is failing to keep up. Many potential homebuyers are being shut out—not by their credit scores, savings, or the real estate market alone—but by well-meaning regulations that quietly drive up costs. The link between energy mandates and affordable housing has become clearer as regulatory costs mount.

This article was informed by and responds to the National Association of Home Builders’ recent statement urging Congress to protect energy choice and maintain flexibility in building energy codes to keep homes affordable (NAHB, Sept. 9, 2025).

What the Numbers Show

• Mandates on energy building codes, appliance standards, and fuel restrictions can raise construction costs. NAHB has testified that building to the 2021 International Energy Conservation Code (IECC) can add up to $31,000 to the price of a new home in practice.
• Cost studies summarizing Home Innovation Research Labs analyses show national average added construction costs on the order of $9,600–$21,400 to comply with the 2021 IECC (varies by climate zone). See NAHB’s aggregated cost table here (Table 1) and the underlying methodology memo here.
• For households, winter heating expenditures depend on weather and region, but U.S. Energy Information Administration (EIA) outlooks consistently show lower average heating expenditures for natural gas households than for electricity-heated homes. See EIA’s Winter Fuels Outlook summaries (Oct. 8, 2024 press release) and the Outlook page here.

Why Energy Choice Matters

• Flexibility lets builders tailor homes to what buyers can afford and what local infrastructure supports.
• Total cost of ownership matters: upfront code mandates may take decades to “pay back” via energy savings, especially in certain climates—see NAHB’s testimony and analyses cited above.
• Market access: Each additional mandated cost can push entry-level buyers out of homeownership.

The Core Issue: Not Agents, Not Builders — Policy

It’s easy to blame market participants, but the most powerful levers are public policies that determine:

• Which energy & building codes are mandatory, and how quickly they tighten
• What appliances qualify for sale and installation
• Which fuels can or cannot be used

NAHB has urged Congress to preserve energy choice and code flexibility to support affordability (press release).

What Needs to Happen

1. Elect representatives who understand cost-benefit tradeoffs and the affordability impacts of codes.
2. Hold decision-makers accountable for rules that raise housing costs without clear, timely consumer payback.
3. Support consumer choice policies, including proposals like the Energy Choice Act, which NAHB supports.
4. Target older housing stock for measured efficiency upgrades where paybacks are clearer, rather than pushing large, front-loaded costs into every new home.

Everyone’s Role – Vote, Speak, Engage

• Vote in local, state, and federal elections—housing rules are often set closest to home.
• Engage: Ask your representatives how proposed code changes affect affordability and energy bills.
• Stay informed: Follow NAHB and EIA updates on code proposals and energy-cost outlooks (links below).

Call to Action

The housing crisis isn’t caused by buyers, sellers, agents, or appraisers. It rests largely with elected officials—federal, state, county, and local—whose policies shape costs and choices. If we want attainable homes, we must vote for leaders who balance consumer protection with affordability and allow practical energy choice.
