Key Points

This bill changes the legal definition of a manufactured home. Currently, these homes must be built on a permanent metal frame with wheels. This new rule would allow homes built in factories to be counted as manufactured homes even if they do not have that permanent frame.
The goal is to make it easier and cheaper to build more houses. By removing the requirement for a heavy metal frame, builders can create factory-made homes that look more like traditional houses but cost less to produce and move.
States would have one to two years to update their own laws. They must prove to the federal government that they treat these new types of homes the same as older manufactured homes when it comes to getting a loan, buying insurance, and paying taxes.
If a state does not update its rules, it will be banned from selling or installing these new types of factory-built homes. This is meant to make sure the rules are the same across the country so builders and buyers know what to expect.
The Department of Housing and Urban Development will provide guides to help states follow the new rules. They will also work with other federal agencies to make sure everyone is using the same definition for these houses.

What Happens Next

Projected impacts based on AI analysis

1-2 years after enactment

States must certify they treat chassis-free manufactured homes the same as traditional ones

Most states have one year to update their laws so these new types of factory-built homes can be legally sold, financed, and insured. States with legislatures that only meet every two years get two years instead.

1-2 years after enactment

States that don't certify face a ban on selling or installing these new homes

If a state misses its deadline, no one in that state can manufacture, install, or sell a factory-built home without a permanent chassis. This creates strong pressure on states to act quickly.

Within 1 year of enactment

HUD publishes model guidance and a public list of compliant states

The Department of Housing and Urban Development will help states update their rules and publish which states are in compliance, so builders and buyers know where these new homes can be sold.
