HURRICANE MITIGATION

BUILDING CODES FOR SOUTH FLORIDA
South Florida Building Code, with its hurricane mitigation provisions, was
implemented in September of 1994 to address the weaknesses associated with the
building envelope that became evident with Hurricane Andrew.

Three main areas of weakness: roof systems, roof sheathing attachment, opening protection.

BUILDING CODES FOR SOUTH FLORIDA
• In 2002 the improved structural portions of the South Florida Building Code were

adsorbed into the Florida Building Code as the High Velocity Hurricane Zone
provisions, applicable within Miami-Dade and Broward Counties.

• It was not until the storms of 2005 that the improved structural building envelope
provisions of the building code were put to the test in actual conditions.

• Hurricanes Katrina and Wilma represented the greatest test, to date, of the
enhanced hurricane mitigation provisions.

• Performance of building envelope systems and components were observed and
assessed in “real world” conditions during 2005 hurricane season.

POST HURRICANE WILMA ASSESSMENT
BUILDING CONSTRUCTION SUCCESSES (selected examples)

• Sheathing attachment (ring shank nails; mandatory sheathing inspection).

• Gable end construction (roof truss bracing; inspections).

• Window, curtain wall and sliding glass door frames. Glass tested under the
current impact tests.

• New shingle roofs (Note: underlayment still in place when shingles were lost).

• Field tile attachment.
