The on -site structure must be designed by a Florida, registered, engineer, to the Florida Building Code and all local codes. This plant - installed site beam is of adequate design for this purpose as long as tie downs and piering are per page 1 of Section 11, Misc. & Final, Inspection section of the installation manual (attached). The attached details, EW-216.2 and PA69-EW-31, are approved by the Manufactured Home Construction & Safety Standards. And, the design loads for the plant -installed site beam, as well as the supporting structure and anchorage are from the FBC and ASCE 7. I can be of further assistance at the above contact information.

AWNING, CARPORTS, PORCHES, UTILITY ROOMS, ETC. Additional structures such as awnings, carports, patio covers or attachments to a Palm Harbor Home have not typically been taken into consideration nor calculated into the design for roof or wind loads. Any additions made to the Home must be self-supporting and shall not interfere with weatherproofing (i.e. shingles, flashing, gutters, siding). However, some Palm Harbor homes have an option to be ordered with a factory installed receiver designed to take the loads of an add -on. In this case, refer to the detail for information on specific nstruction-and-requirementsi• FACTORY INSTALLED DOUBLE SECTION HOME �_ RECEIVER / BY OTHERS SITE INSTALLED BY OTHERS Perimeter piers and_footer notes: 1.

Vertical tie connections have been factory installed to handle the uplift and overturning load from the 'main unit along with the additional load from the awning, connection to the main unit. (brackets @ 5'-4" o.c. max.) 2. The factory installed receiver is designed to handle the additional uplift and downward loads from the connection of the awning to the main unit. 3. The awning roof and roof support away from the main unit must be designed (by others) to carry all loads to the ground. The design of the awning connection along with weatherization (by others) must be designed to carry the appropriate load into the factory -installed receiver. The design must be according to the loads and requirements of the IRC 2003 for exposure V. 4. Factory installed members were designed for awning loads based on 90 mph (3 second gust) winds for wind zone 1, 120 mph (3 sec. gust) winds for wind zone 2, and 140 mph (3 sec. gust) winds for wind zone 3. This is in accordance with IRC 2003, exposure V. 5. For approved lateral load resisting systems' installation requirements and number required, refer to other pages in the Palm Harbor Homes installation manual. 6. No stabilizer plates are required at anchors loaded in direct (in -line) pull. 7. . This design is for 140" minimum floor width and 186" maximum floor width on the main units and for 20 psf roof live load in'all wind zones. 8. Maximum pier height including I-beam for wind -zone. 1 is 52" and minimum height is 31". Pier heights for wind zones 2 and 3 are based on vector system design.
