        Question about the High Velocity Hurricane Zone (HVHZ)  | 
      
      
        | 
        High Velocity Hurricane Zone (HVHZ) | 
        The High Velocity Hurricane 
        Zone (HVHZ) is sometimes called The Dade County Code. If you are in 
        Broward County or Miami-Dade County
        you are in the 
        High Velocity Hurricane Zone (HVHZ). In this area, you must have HVHZ 
        approved products. The wind pressure required or “design pressure” (DP) 
        is higher and the anchoring method is a little more stringent.
         
        For the rest of the State of Florida, the governing authority is Florida 
        Building Code (FBC). All products must have FBC approval. The approval 
        required will depend on which area or zone you are in.  |

    Florida Product 
    Approval | 
        By Florida 
    state law, building envelope components such as roofing, shutters,  
    doors and windows are required to have a Florida Product Approval that 
    provides evidence that the product is suitable for use in the state of 
    Florida based on standards set in the current Florida Building Codes. 
    Specific limitations of use are provided that limits the approved product’s 
    use to rated  
    structural loads.  | 
      
      
        | 
    Miami-Dade Notice Of 
    Acceptance | 
        A Miami-Dade 
    Notice Of Acceptance (NOA) is a local product approval to meet the code 
    criteria in the High Velocity Hurricane Zone (HVHZ) as defined by the 
    Florida Building Codes (FBC). | 
      
      
        | 
    Product Testing | 
        With regards 
    to the Florida Building Code requirements, the testing is the same. The same 
    evaluation protocols are followed and the same performance and quality 
    assurance criteria are required. A product with a statewide Florida Product 
    Approval that shows “Approved for use in the HVHZ” has met the same testing 
    standards as a product with a Miami-Dade NOA in compliance with the Florida 
    Building Codes for both impact and non-impact rated products.

    Miami-Dade or Florida 
    Product Approval | 
        You can use 
    either a Miami-Dade NOA or a Florida Product Approval that includes the 
    approval for use in the HVHZ. Only one is necessary. |

    Local Buidling 
    Departments | 
        Florida law 
    allows for the option of either a statewide product approval or local 
    product approval for use in the HVHZ. Products designated as approved by the 
    Florida Department of Community Affairs (FDCA) on the department’s Building 
    Code Information System (http://www.floridabuilding.org) 
    must be accepted as meeting the Florida Building Code within  their 
    specified limitation of use and such products are available for use 
    immediately upon approval. Should you have any questions, please contact the 
    Florida Department of Community Affairs at 850-487-1824. |
