Manufactured Homes: What the Federal HUD Code Actually Covers

The HUD Code: One National Construction Standard

A manufactured home is built entirely in a factory to the federal Manufactured Home Construction and Safety Standards -- commonly called the HUD Code, codified at 24 CFR Part 3280 -- which has applied nationwide since 1976 and is administered by the US Department of Housing and Urban Development. Because it's a federal preemptive standard, every state must allow homes built to it, and a HUD certification label affixed to the home documents that compliance. This is a genuinely different regulatory track from a modular home, which is factory-built but constructed to local/state building code instead -- see our companion guide to modular homes for that distinction in full.

The historical hallmark of a manufactured home is a permanent steel chassis, which allows it to be transported by road and distinguishes it structurally from modular and site-built construction. As of 2026, that specific requirement is in active transition: the 21st Century ROAD to Housing Act (signed into law in mid-2026) revised the federal definition of "manufactured home" to permit construction with or without a permanent chassis, and HUD has proposed a corresponding rule change -- still moving through the federal rulemaking process as of this writing -- that would drop the chassis requirement specifically for the upper stories of multi-story manufactured homes. Confirm the current rule status directly with HUD before assuming either the old or new standard applies to a specific home.

Federal Construction Standard, Local Placement Rules

Federal preemption covers how the home is built -- it does not preempt local zoning about where a manufactured home can be placed. Many zoning ordinances specifically call out manufactured homes as their own use category, sometimes restricting them to designated manufactured-home parks or specific zoning districts, sometimes requiring a minimum age or a permanent foundation for placement outside those districts, and in some jurisdictions prohibiting them from certain residential districts outright. This is meaningfully different from a modular or site-built home, which typically isn't singled out this way. Confirm your specific parcel's zoning treatment of manufactured homes directly with the county before buying one to place -- don't assume from a neighboring county's rules. See our national guide to zoning.

Installation once the home reaches the site is governed by a separate federal standard, the Model Manufactured Home Installation Standards (24 CFR Part 3285), covering foundation, anchoring, and setup -- states can enforce their own installation program if it meets or exceeds this federal floor, so ask your installer which standard applies in your state.

Deed Restrictions Are a Separate, Often Stricter, Barrier

Deed restrictions and HOA covenants are private agreements, not government action, so federal preemption of the HUD Code has no bearing on them at all. It's common, especially in platted subdivisions and some rural developments, for recorded covenants to prohibit manufactured or "mobile" homes entirely, even in areas where zoning would otherwise allow one. Because these restrictions are enforced independently of zoning and are typically read strictly by courts, a manufactured-home prohibition in your deed is very difficult to override -- read the actual recorded restrictions for your parcel before you buy a home to place on it. See our national guide to deed restrictions.

Financing: Real Property vs. Personal Property

How a manufactured home is titled changes how it's financed. If it's permanently affixed to a foundation on land you own and the title is retired in favor of real-property status (a process that varies by state), it can generally qualify for a conventional, FHA, VA, or USDA mortgage like any other home. If it remains titled as personal property -- common when the home sits on rented land or hasn't gone through that conversion -- it's typically financed instead with a chattel loan, which usually carries a shorter term and a higher interest rate than a real-property mortgage. Ask a lender specifically which category your situation falls into before assuming standard mortgage terms apply.
