ICC Publishes Response Without My Initial Inquiry
The International Code Council (ICC) has published its official response on a second preemption inquiry that I submitted regarding the ICC/THIA Standard 1215 on the Design, Construction, Inspection and Regulation of Tiny Houses for Permanent Occupancy. What’s missing is the document that prompted it—my preemption inquiry outlining the federal legal conflicts at issue. Scroll down for an executive summary.
Where To Find Only ICC's Replies
To find only their response go this page, click on documents on the right, go to Resources and then click on Preemption where you will find both of only their replies to both of my preemption inquiries.
That omission is not minor. In its April 22, 2026 letter responding to a preemption inquiry, the International Code Council (ICC) addressed the applicability of federal law while not engaging with arguments that ICC 1215 regulates chassis-based transportation elements such as weights, loads, highway movement, and structural transport systems—areas governed by federal motor vehicle law. Those laws establish uniform national standards, including VIN requirements and certification labeling. ICC 1215 instead relies on private data plates and internal serial systems, creating a separate compliance framework.
One Example Illustrates The Problem Clearly:
- ICC 1215 requires a “Small Residential Unit Data Plate” placed inside the structure that includes the gross weight of the structure
- Once mounted on a chassis and moved on public roads, that weight is no longer a building metric—it becomes regulated vehicle weight
- Federal law governs that weight through VIN-linked certification labels, axle ratings, and tire/loading placards affixed to the chassis—not through an interior building plate
ICC 1215 then compounds the issue by requiring DOT compliance for loads and weights shown on this data plate—while omitting the federally required certification system entirely. That creates an impossible condition: compliance is required, but the lawful mechanism to prove it is removed.
The contradiction is direct. ICC claims these units fall outside motor vehicle jurisdiction, yet the standard regulates the very transportation elements federal law controls. You cannot disclaim jurisdiction while exercising it.
And The Record Goes Further
- This is not a passive oversight or technical gap.
- Documented communications show awareness of federal motor vehicle requirements—including VIN, FMVSS applicability, and HUD overlap—paired with recommendations to avoid those classifications while continuing to regulate transportation components.
That combination—knowledge of the federal framework alongside a deliberate shift to alternative mechanisms—transforms this from a drafting issue into a structural conflict with federal law.
Chassis-based dwellings do not begin as buildings—they begin as transportable products in interstate commerce, subject to federal identification, certification, and transportation requirements before they are ever placed on land. ICC 1215 skips that legal stage entirely.
Publishing a response without the underlying inquiry presents only half the record. The full correspondence shows that the federal conflict was clearly raised, fully documented, and left unresolved.
The question was asked. The law was cited. The conflict was identified. The response avoided all three.
Uniting The Motor Vehicle Path With The Structure Path Is The Road To Legal Dwellings
For almost two years I have tried to get the ICC 1215 committee to recognize motor vehicle law. The duo nature of tiny houses on wheels must be recognized to create a legal dwelling to obtain a mortgage and to be accepted in jurisdictions. The path to compliance for tiny houses on wheels is to integrate the motor vehicle compliance path with requirements of a structure, so it meets both the requirements of the road, and for legal placement and for the structure to be recognized as real property. We also need to create provisions that allow tiny houses on wheels to be legally placed on leased land where the unit remains personal property.
The ICC 1215 committee is blocking the very steps needed. Learn more.
The Supremacy Clause
“This Constitution, and the Laws of the United States which shall be made in Pursuance thereof; and all Treaties made, or which shall be made, under the Authority of the United States, shall be the supreme Law of the Land; and the Judges in every State shall be bound thereby, any Thing in the Constitution or Laws of any State to the Contrary notwithstanding.”
ICC Stated
“You provided no support or authority for your assertion that once weight is invoked, federal transportation law governs.”
ICC Stated
“In summary, your letter did not provide any persuasive reason why the inclusion of the weight information on a data plate inside the structure was likely to be preempted by federal law.”
My Reply
“The law speaks for itself.”

Tiny House Ballad-Our Cry For Wheels And Steels
This is a song I wrote about what the entire nation is facing because of corporate interests that have taken over housing and the battle for tiny houses on wheels.
