Manufactured Homes Without a Steel Chassis Could Expand Starter Supply—If Zoning Allows It

Manufactured housing is getting a technical reset

Manufactured housing has long been one of the most scalable ways to add lower-cost homes quickly. In 2026, a key federal change targeted one of the product’s most visible legacy features: the permanent steel chassis. Under the 21st Century ROAD to Housing Act, new manufactured homes can be built without that permanent chassis, and states are directed to ensure chassis-free homes receive comparable treatment for financing, titling, insurance, taxes, transport, and installation.

Why does that matter? Removing the chassis can reduce materials and open up more design flexibility, including options that look and function more like conventional site-built houses—potentially lowering neighborhood resistance that’s often rooted in appearance and outdated assumptions about the product.

The catch: local zoning still decides what gets built

Even with a federal door opened, local land-use rules still determine where manufactured homes can go. Recent Realtor.com analysis (cited across industry coverage) found that only about 17% of zoned land nationwide explicitly allows manufactured-home communities. [realtor.com][realtor.com]

That statistic helps explain why production capacity alone won’t solve the starter-home shortage. Many jurisdictions block manufactured housing through:

• **Use restrictions** (not allowed in most residential districts)
• **Minimum floor-size rules** that eliminate smaller, entry-level formats
• **Architectural/design standards** that don’t match factory-built realities
• **Discretionary approvals** (special permits/conditional-use hearings) that add time and uncertainty

In practice, “by-right” placement—where a compliant unit can be installed without a political or discretionary vote—often determines whether projects pencil. [realtor.com][realestatenews.com]

Where the shift could matter most

Realtor.com’s research argues that the biggest lift from chassis-free manufactured homes may show up in metros that combine (1) relatively affordable land, (2) expensive traditional new construction, and (3) a low share of starter-home listings. In those markets, a cheaper factory-built option can fill a real gap—*if* local codes allow it. [realtor.com][realestatenews.com]

One reported ranking placed Hartford, Connecticut at the top of the list, followed by markets including Denver, Allentown, Albuquerque, and Colorado Springs. The common thread is not necessarily size; it’s the mismatch between entry-level demand and the cost structure of site-built delivery. [realestatenews.com][inman.com]

What to watch next (and what can actually move the needle)

The next phase is less about federal definitions and more about local implementation. Three practical signals to track:

1) **Zoning updates that expand by-right districts.** Allowing manufactured homes in more residential zones—paired with clear installation standards—reduces uncertainty and speeds up delivery. [realestatenews.com]

2) **Standards that reflect today’s product.** If rules were written for an older “mobile home” mental model, they can inadvertently ban modern units, especially as designs evolve post-chassis. [inman.com][realestatenews.com]

3) **State-level parity for paperwork and lending.** The law’s promise depends on how quickly states align titling, taxation, and financing treatment so chassis-free units don’t fall into a gray zone that spooks lenders and insurers. [realtor.com][inman.com]

Manufactured housing won’t be a universal fit, and it won’t overcome every siting constraint. But if jurisdictions want more attainable starter-home supply without waiting years for site-built delivery, the evidence in this week’s reporting points to one bottom line: federal policy can enable the product, but local zoning determines the pipeline.
