- Building code changes are the largest regulatory cost, totaling $40,288 per home.
- Regulatory costs have increased by over 40% since 2021.
- The ROAD Act may offer savings through streamlined federal environmental reviews and modernized manufactured housing rules.
- The legislation has limited direct impact on local zoning, impact fees, and design mandates.
The 21st Century ROAD to Housing Act is under consideration, but homebuilders and developers are already grappling with significant regulatory costs that impact new home prices. According to the National Association of Home Builders (NAHB), government regulations at all levels now add an average of $131,734, or 26.4%, to the final price of a new single-family home. This figure represents a substantial increase from previous years, more than doubling since 2011.
The largest component of this regulatory burden is building code changes, which account for an estimated $40,288 per home. Other significant costs include builder fees after lot purchase ($20,154), architectural design standards ($16,117), and land dedications ($13,593). Regulatory delays, averaging seven months during lot development and over six weeks during construction, also contribute to increased costs by slowing capital velocity and disrupting project timelines.
The ROAD Act's effectiveness is seen as mixed. Its most practical potential lies in areas where the federal government has direct control, such as streamlining environmental reviews and modernizing manufactured housing standards. Provisions that reduce duplicative federal reviews or improve access to financing could translate into real savings. However, the legislation's ability to influence local land-use politics, zoning, impact fees, and design preferences is more limited. While Congress can encourage zoning reform and reward jurisdictions that increase housing supply, it cannot directly force local governments to change their rules.
Ultimately, the bill's immediate value may be more political and informational, providing a federal reference point and common vocabulary for housing supply issues, and empowering pro-housing local officials. The substantial regulatory cost stack highlights that housing affordability is not solely a function of mortgage rates, labor, or materials, but also a significant "rules story" that impacts both builders' balance sheets and homebuyers' initial costs.
