History
2000 B.C.
Code of Hammurabi which stated:
If a builder builds a house for someone, and
does not construct it properly, and the house
which he built falls in and kills its owner,
then that builder shall be put to death.
1600’s through 1800’s (United States)
The first building codes in the United States were developed to address fire safety
In 1630, Boston outlawed chimneys made of wood and thatch roof coverings.
1900’s (United States)
Different model codes developed in different regions of the United States:
(BOCA Code): Building Officials Code Administrators (East Coast and throughout the Midwest)
(Standard Building Code): Southern Building Code Conference International (Southeast)
(Uniform Building Code): International Conference of Building Officials (West Coast)
Pre-1950’s (Florida)
1. Prior to 1950, Counties and municipalities had their own building codes or they adopted a model code.
2. Example: the city of Miami Beach building department was established in 1925 and the city had its own building code until the 1950’s when the city adopted the South Florida building code.
1950’s (Florida)
1. Hurricanes during the 1950’s led to the development of the South Florida Building Code (“SFBC”) (Model Code)
2. A series of studies revealed that the current model codes were not adequate.
3. The model codes at that time addressed problems such as snow loads and seismic forces. However, none addressed severe wind loads
4. SFBC Adopted by Dade County (12-31-1957)
1970’s (Florida)
In 1974, Florida first mandated statewide building codes. This law required all municipalities and counties to adopt and enforce one of the four state-recognized model codes known as the “State Minimum Building Codes”.
F.S. 553.73
1. Standard Building Code
2. EPCOT Code
3. One and Two Family Dwelling Code
4. The South Florida Building Code
Hurricane Andrew (8-24-1992)
65 Deaths
$26.5 billion in damages
Unlike most hurricanes, the vast majority of damage was due to wind
In Dade County alone, 90% of homes had roof damage
International Code Council (1994)
1.Created by:
1.Building Officials and Code Administrators International (BOCA)
2.International Conference of Building Officials (ICBO)
3.Southern Building Code Congress International (SBCC)
2.Established to develop a single national model code
Florida Building Codes Study Commission (July, 1996)
1. Established to evaluate the existing system and to recommend ways to improve or reform system.
1.Did Florida need a stronger code?
2.Or, was the problem code compliance?
2.Commission found a complex and confusing patchwork system of different codes administered and enforced differently, by more than 400 local jurisdictions.
3.It became clear that Florida needed a single, statewide building code system.
1998 Florida Legislature
1. Legislature mandated development of a new building code system through HB 4181
2. HB 4181 directs the development of:
1. Florida Building Code
2. Florida Building Commission
3. Statewide system for product approvals.
2000
1. First edition of the International Building Code is published

2. Several codes were Discontinued

BOCA CODE
UNIFORM BUILDING CODE
STANDARD BUILDING CODE
March 1, 2002
1. Florida Building Code Implemented
2. Chapter 553 (Florida Building Codes Act) of the Florida Statutes was amended to create a single statewide building code.
3. Adopted International Building Code
4. Model Codes are developed by different organizations (i.e. International Building Code was developed by the International Code Council) and are adopted by jurisdictions (Florida has adopted the International Building Code)
March 15, 2012
2010 Florida Building Code takes effect

Chapter 1- Administration (Permits)
General.
Construction or work for which a permit is required shall be subject to inspection by the building official and
such construction or work shall remain accessible and exposed for inspection purposes until approved. Approval as a result of an inspection shall not be construed to be an approval of a violation of the provisions of this code
or of other ordinances of the jurisdiction.
Inspections presuming to give authority to violate or cancel the provisions of this code or of other ordinances of the jurisdiction shall not be valid.
It shall be the duty of the permit applicant to cause the work to remain accessible and exposed for inspection purposes.
Neither the building official nor the jurisdiction shall be liable for expense entailed in the removal or replacement of any material required to allow inspection.
(FBC 109.1)
Required inspections.
The building official upon notification from the permit holder or his or her agent, shall make the following inspections, and shall either release that portion of the construction or shall notify the permit holder or his or her agent of any violations which must be corrected in order to comply with the technical codes. The building official shall determine the timing and sequencing of when inspections occur and what elements are inspected at each inspection.

Chapter 1- Administration (Inspections)
Threshold Buildings:
The enforcing agency shall require a special inspector to perform structural inspections on a threshold building pursuant to a structural inspection plan prepared by the engineer or architect of record. The structural inspection plan must be submitted to the enforcing agency prior to the issuance of a building permit for the construction of a threshold building. The purpose of the structural inspection plans is to provide specific inspection procedures and schedules so that the building can be adequately inspected for compliance with the permitted documents.
The special inspector may not serve as a surrogate in carrying out the responsibilities of the building official, the architect or the engineer of record. The contractor's contractual or statutory obligations are not relieved by any action of the special inspector.
F.B.C. 110.3.7 (2010)
Approval required.

Wind Loads
Wind Loads (ASCE 7-10)
Changes to ASCE 7:
1. Removal of the Importance Factor which is replaced by risk categories.
2. New wind speed maps for risk categories
3. Revised load factors
4. Reinstating Exposure D in hurricane prone regions
New Wind Speed Maps
Maps vary by risk category
Separate maps are provided for each of the following risk categories (I,II, III, and IV)
Category 1:
Buildings that represent a low hazard to human life (screen enclosures, farms)
Category II:
Buildings except those listed in Categories I, III and IV.
Category III:

Buildings that represent a substantial hazard to human life (schools)
Category IV:
Buildings designated as essential facilities (emergency shelters)
Wind Loads (ASCE 7-05 vs. ASCE 7-10)
ASCE 7-05:
Qz = .00256 Kz*Kzt*Kd*V2*
I
QZ = velocity pressure evaluated at mean roof height (psf)
Kz = velocity pressure exposure coefficient
Kzt = topographic factor
Kd = wind directionality factor
V = basic wind speed from ASCE 7-05 maps (
146
mph for Miami-Dade)
I = Importance factor

Design Pressure = Qz(Gcp-GCPi)

ASCE 7-10:
QZ = .00256 Kz*Kzt*Kd*V2
QZ = velocity pressure evaluated at mean roof height (psf)
Kz = velocity pressure exposure coefficient
Kzt = topographic factor
Kd = wind directionality factor
V = basic wind speed from ASCE 7-10 maps (
175
mph for Miami-Dade)

Design Pressure = Qz(GCp-GCpi)
x .6
(used to convert from strength design to allowable stress design)
Wind Loads (Wind borne debris region)
Areas within hurricane prone regions located:
Within 1 mile of the coastal mean high water line where the ultimate design wind speed is Vult = 130mph, or greater.
In areas where the ultimate design wind speed Vult = 140 mph, or greater.
Wind Loads
In Miami-Dade the new wind load maps with revised formula will give you a lower wind pressure than before, for Exposure C and very similar loads for Exposure D.
The Wind Borne Debris region has been expanded throughout state.
In Miami-Dade the wind velocity (3-second gust) used in structural calculations shall be as follows (HVHZ):
Risk Category I: 165 mph
Risk Category II: 175 mph
Risk Category III and IV: 186 mph
Interpretations
It is the intent of the Legislature that the Florida Building Code be interpreted by:
Building officials
Local Enforcement Agencies, and
