A new NAHB study shows regulatory costs have jumped nearly 40 percent in five years, adding $131,734 to the price of a typical new single-family home.
Government regulations now add $131,734 to the price of a typical new single-family home. That is 26.4 percent of the average sale price of $499,500 as of January 2026.
The finding comes from a new study by the National Association of Home Builders (NAHB). It tracked new home construction regulatory costs across five survey cycles dating back to 2011.
The growth has been steep:
That is a 40 percent jump in five years and more than double the 2011 figure.
NAHB chairman Bill Owens said excessive regulation is deepening the nation’s housing affordability crisis. He called on policymakers to remove requirements that are pricing buyers out of the market and slowing construction of new homes and apartments.
New home construction regulatory costs: where they come from
The $131,734 splits across two phases:
- construction phase: $84,939 (17.0 percent of sale price)
- land development phase: $46,795 (9.4 percent of sale price)
Building code changes are the single largest driver. Nearly all builders surveyed — 97.4 percent — said code updates over the past decade added to their costs. That one category alone adds $40,288 per home, or 8.1 percent of the sale price. That is more than double any other individual cost item in the study.
The full breakdown, per the NAHB report:
| Cost category | Per home | Share of sale price |
|---|---|---|
| Building code changes (past 10 years) | $40,288 | 8.1% |
| Permit, inspection, and hook-up fees | $20,154 | 4.0% |
| Architectural design standards (construction) | $16,117 | 3.2% |
| Land dedicated to government or left unbuilt | $13,593 | 2.7% |
| Compliance fees and required studies (development) | $10,755 | 2.2% |
| Design standards beyond ordinary (development) | $10,583 | 2.1% |
| Zoning approval costs | $7,007 | 1.4% |
| OSHA and labor compliance (construction) | $6,748 | 1.4% |
| OSHA and labor compliance (development) | $2,377 | 0.5% |
| Pure cost of delay — development | $2,480 | 0.5% |
| Pure cost of delay — construction | $1,632 | 0.3% |
| Total | $131,734 | 26.4% |

Delays compound every other cost. 94.2 percent of developers said regulatory compliance caused delays averaging roughly seven months. Among builders, 93.4 percent reported delays averaging just over six weeks.
Each delay accrues interest on development and construction loans — costs passed on to the buyer. The price gap between new and existing homes is already widening as those costs accumulate.
What this means for US mortgage brokers
Regulatory costs don’t appear on a loan application, but they are built into every new home price a buyer sees.
Brokers can use this data in a few practical ways:
Explain the new versus existing home price gap
A buyer comparing a $499,500 new build against a resale at $380,000 may not understand the difference. Brokers can point to the $131,734 in regulatory compliance costs as part of that new home price. Explain that these are costs that have nothing to do with finishes or location.
Set realistic timelines for construction loan clients
The average time from zoning application to start of site work is 15.1 months. From site work to lot sale to a builder takes a further 11.5 months. Clients financing new builds need to factor those timelines into their construction loan strategy, particularly around rate locks.
Guide clients toward lower-regulation markets
Regulatory costs vary widely by jurisdiction. Brokers in high-regulation markets — coastal California, parts of the Northeast, metro Texas — can steer clients toward builders who use pre-designed plan libraries. This strategy reduces compliance exposure and shortens timelines.
Anchor the affordability conversation in supply
NAHB’s 2026 study estimates the US has a structural housing deficit of 1.2 million units. Regulatory costs are one reason supply has not kept pace. Brokers who can explain why new home supply stays constrained add real value for clients weighing whether to buy now or wait.
Pressure on the broader market
The regulatory burden sits alongside other cost pressures builders already face. Tariffs announced since January 2025 are expected to add roughly $17,500 per home in construction costs, according to analysis by the Center for American Progress. Builders have been offering deeper concessions to buyers stretched by high prices and borrowing costs. This trend is further slowing the pace of new construction.
The White House issued an executive order in March 2026 directing the Department of Housing and Urban Development to develop regulatory best practices for state and local governments. It called for streamlined permitting, capped timelines and fees, and limits on the retroactive application of new building codes.
NAHB’s study identifies new home construction regulatory costs as one of several supply constraints, which include:
- tariffs
- skilled labor shortage
- fewer available lots
- tighter lending conditions
For mortgage professionals navigating purchase affordability in today’s tight market, those costs remain a direct constraint on what gets built and what gets sold.
