Learn how to inspect the roof system during a home inspection. In response to public comments, HUD returned the proposal to MHCC for further evaluation. After further consideration, MHCC submitted to HUD an amended version of its original proposal on roof truss testing. HUD was in agreement with the majority of MHCC's revised recommendations on roof truss testing which were published as a proposed rule on June 1. Many of MHCC's recommendations are included in this final rule. HUD identifies MHCC's proposals that were not accepted, or that were modified in light of public comments received or upon further evaluation, and provides its reasons for not accepting or for modifying these proposed revisions.

SUPPLEMENTARY INFORMATION: I. Background. The National Manufactured Housing Construction and Safety Standards Act of 1. U. S. C. 5. 40. 1- 5. Act) authorizes HUD to establish the Federal Manufactured Home Construction and Safety Standards (Construction and Safety Standards), codified in 2. CFR part 3. 28. 0. The Act was amended by the Manufactured Housing Improvement Act of 2. Pub. 1. 06- 5. 69), which expanded the Act's purposes and created MHCC. Congress established MHCC to provide periodic recommendations to the Secretary to adopt or revise provisions of the Construction and Safety Standards. In 2. 00. 2, MHCC began considering revisions to the Construction and Safety Standards and, in 2. After considering public comment received on the proposed rule, HUD returned the proposal on truss testing procedures to MHCC. As indicated in the preamble of HUD's final rule published in the Federal Register on November 3. FR 7. 20. 24), which followed the December 1, 2. HUD stated that truss testing procedures are too important a safety consideration to leave unaddressed. In returning the rule, HUD also stated that the standards had not been modified in a number of years and needed to be examined to determine whether they were adequate to protect homeowners in all geographic areas of the country. HUD's review of damage assessments following Hurricane Charley reinforced its conclusion regarding the need for the MHCC to ensure that truss testing procedures were updated and adequate to protect homeowners from roof and structural damage accompanying high wind events. HUD requested MHCC to work expeditiously to reevaluate and resubmit new proposals for truss testing procedures. As a result, the Truss Test Task Force of MHCC's Standards Subcommittee was established.

Five teleconferences of this task force were held, and the full MHCC held two teleconferences to review and vote on new truss testing procedures. HUD worked closely with MHCC throughout the review and reevaluation process, and agreed with the majority of the proposals to strengthen the truss testing procedures made by MHCC, but made editorial revisions and modified the Start Printed Page 4. MHCC's proposal on uplift testing. Those recommendations and modifications were included in a proposed rule published in the Federal Register on June 1. FR 3. 40. 64). After careful review of the public comments received in response to the proposed rule, HUD made additional editorial and other revisions and further modified the MHCC's proposal regarding uplift testing. HUD's additional revisions in response to public comment are reflected in this final rule. As a result of this final rule, the required truss testing procedures reflect the current industry standards and methods by which trusses are tested by truss fabricators. These procedures also provide flexibility in testing by reducing the amount of time required for the proof load test. Most importantly, they improve the performance and safety of trusses in high wind areas and high snow load areas, and ultimately reduce property damage and prevent injury and loss of life resulting from high wind events such as hurricanes and tropical storms, as well as injuries and deaths that occur from collapsed roofs under heavy loads. Table A identifies the changes made to the truss testing standards as a result of this final rule. Table A—Comparison of Roof Truss Testing Procedures. Previous testing requirements.

Note—The previous standards do not specify either the inverted or upright uplift load test method. Therefore, either method was acceptable under the existing standards and most roof truss designs were certified using the inverted/nonconservative roof truss testing procedure. II. Analysis of Public Comments. The public comment period on the proposed rule closed August 1. Comments were submitted by suppliers of roof trusses, manufactured home producers, a Design Approval Primary Inspection Agency, and two manufactured housing trade associations. All public comments can be found and reviewed at www. A. The Comments Generally. Comment: Generally, the commenters expressed various concerns about HUD's proposed changes to the roof truss testing requirements. In particular, the commenters questioned the need to requalify and retest all existing roof truss designs based on past truss performance under snow and wind loading. They also expressed concerns on significant cost increases to consumers and the estimated time (1. HUD Response: HUD agrees that the risk against truss failure in snow load areas is minimal based on past performance. As a result, the final rule limits the retesting to new truss designs in all three wind zones, and to the estimated 1. Wind Zones II and III) where the reliability and enhanced protection is needed to mitigate against future wind damage and to enhance wind safety in manufactured homes. HUD is also delaying implementation for 1. Wind Zones II and III and minimize disruption to the availability of qualifying trusses. HUD acknowledges that wind damage to homes produced to meet its high wind standards has been reduced in wind events that have occurred since the implementation of the high wind requirements. However, while the damage to those homes has been relatively minimal, questions remain about the intensity of the windstorms and whether they were considered to be design wind events or were at lower wind speeds than required to be resisted by the standards. Comment: Commenters also questioned the need to eliminate the inverted test procedure currently being used to assess uplift resistance of roof trusses in high wind areas. One commenter (a truss supplier) recommended that a higher factor of safety or overload of 2. HUD for the upright uplift wind test of 1. HUD Response: HUD agrees with the commenter. As a result, the final rule allows the use of either upright or inverted testing for Wind Zones II or III, with a higher factor of safety of 2. Comment: Commenters questioned the cost impact of increasing the overload factor of safety from 1. HUD Response: HUD recognizes this issue and, in the final rule, allows both the 2. B. Specific Issues for Comment. Question 1: Under the proposed rule, the proof load test or the ultimate load test can be used to qualify trusses in high snow load areas. Should the more stringent and reliable ultimate load test procedure be required only to qualify roof trusses designed for use in high snow load areas, such as the North and Middle Roof Load Zones, where the risk of roof and truss failure is greater? Start Printed Page 4. Comment: The commenters indicated that HUD should maintain the option to use either test method in all roof load zones and that HUD should not adopt different requirements for North and South roof load zones because of past performance history of roof trusses in high snow load areas. HUD Response: HUD agrees with the commenters and has not specified roof load zones for which the proof load or ultimate load test procedure must be used in the final rule. Question 2: Should the spacing between hydraulic or pneumatic cylinders for the test fixture be increased from 1. Figures 3. 28. 0. Should the distance between friction pads along the top chord of the truss of the test fixture be increased from 6 inches to 1. Figure 3. 28. 0. 4. Should the distance between 1- inch straps attached around the cylinder shoe and the top chord of the truss of the test fixture be increased from 6 inches to 1. Figure 3. 28. 0. 4. Comment. The commenters indicated that the loading cylinders should be maintained at 1. HUD Response: HUD agrees with the commenters that the cylinders spacing needs to be maintained at 1. Question 3: Should the overload period for all wind uplift tests be increased from 1 minute to 3 hours, as is currently required for uplift tests in the standards for the inverted test procedure?
