TeraSun Systems – Regulatory White Paper
Establishing the National Transport Standard for Chassis‑Free Manufactured & Modular Structures
Overview
HUD’s removal of the permanent chassis requirement marks the most significant structural reform in manufactured housing since 1976. This change modernizes the industry—but it also eliminates the only federally recognized transport safety anchor. Without a replacement standard, manufacturers, carriers, state DOTs, and enforcement agencies face a national safety and compliance gap.
TeraSun Systems’ formal white paper provides the first comprehensive framework for a certified, engineered, DOT‑compliant transport and placement standard for chassis‑free structures.
This document is designed for:
- Federal agencies (HUD, DOT, FMCSA)
- State DOT directors and CVE enforcement
- Manufacturers and modular builders
- Insurers and risk managers
- Legislators and policy staff
What the White Paper Addresses
1. The Regulatory Gap
HUD removed the chassis but did not define what replaces it. The white paper outlines:
- The loss of the transport safety anchor
- DOT/FMSCA limitations under current rules
- State‑level permitting inconsistencies
- Liability and insurance uncertainty
2. The Need for a Certified Carrier Standard
The paper proposes a national framework including:
- PE‑certified carrier systems
- Standardized pre‑departure inspections
- Real‑time transport monitoring
- Digital lifecycle records
- HUD–DOT–FMCSA coordination
3. Technical Feasibility
TeraSun demonstrates that a certified standard is achievable today through two patented platforms:
- Reusable Hydraulic Transport & Precision Placement Platform
- Variable‑Width Self‑Propelled Modular Carrier System
These systems provide engineered load paths, DOT‑compliant road mode, precision placement, and digital tracking.
Why This Matters
For Regulators
A clear, enforceable replacement for the HUD chassis.
For State DOTs
Consistent permitting, safer roadside enforcement, and reduced administrative burden.
For Manufacturers
A compliant, insurable, scalable transport method for chassis‑free production.
For Insurers
Predictable risk profiles and standardized underwriting criteria.
For the Industry
A unified national standard that supports the next generation of factory‑built housing.
Key Recommendations
The white paper calls for:
- A joint HUD–DOT–FMCSA rulemaking
- Adoption of PE‑certified carrier systems
- Standardized enforcement criteria
- Multi‑state coordination
- Pilot programs to validate engineered carriers
