The Department of Highway Safety and Motor Vehicles (DHSMV) has provided Chapter 15C-2.0081, which explains the Mobile/ Manufactured Home Repair and Remodeling Code. Under this chapter paragraph (1) a states "Additions, including, but not limited to add-a-rooms, roof-over and porches shall be free standing and self supporting with only the flashing attached to the main unit unless the added unit has been designed (by an Engineer) to be married to the existing unit. All additions shall be constructed in compliance with the Florida Building Code (FBC)."
Building Construction Services Department will follow DHSMV Chapter 15C-2 and the Florida Building Code R 302 Exterior Walls and R309 Garages and Carports when adding an attached or a detached room addition.
- If a garage is attached or detached it shall comply with R309, if located less than 3 foot from a dwelling unit it shall be protected with not less than ½" gypsum board applied to the interior side of the exterior wall of the garage.
- If garage wall is located more than 3 foot away from a dwelling unit no interior drywall is required.
- All other room additions as listed above in DHSMV chapter 15C-2 shall be followed and constructed by the FBC.
- The Engineer that designs the addition, add-a-rooms, roof–over’s, porches and raised wood floors can sign and seal plans to be married to the existing mobile home. In this case, we will not require the mobile home manufacturer to approve such attachments.
