This final rule establishes new Model Manufactured Home Installation Standards (Model Installation Standards) for the installation of new manufactured homes and includes standards for the completion of certain aspects necessary to join all sections of multi- section homes. The National Manufactured Housing Construction and Safety Standards Act of 1974 requires HUD to develop and establish Model Installation Standards after receiving proposed installation standards from the Manufactured Housing Consensus Committee (MHCC). HUD received and reviewed the MHCC's recommended proposed model installation standards and published a proposed rule for public comment. Based on HUD's review of the comments that were submitted, including those from the MHCC, a number of revisions to the proposed rule have been made in this final rule. This final rule also incorporates certain amendments to definitions contained in the Manufactured Home Construction and Safety Standards (MHCSS) that are affected by definitions provided in the Model Installation Standards.
