Requires the Secretary of Housing and Urban Development to review FHA construction‑financing practices that may block use of modular home methods, identify regulatory barriers, publish a report within one year, and initiate a rulemaking (with public comment) to consider alternative draw schedules for modular construction. Authorizes HUD to award a grant to study a standardized module coding/serialization system (linked to financing and security) and authorizes whatever funds are necessary to carry out that study.
