The Florida Building Code has separate volumes for residential and commercial construction. The FBC Residential (FBC-R) applies to one- and two-family dwellings and townhouses; the FBC Building (FBC-B) applies to all other buildings. Understanding which volume applies to your project is the first step in code compliance.
When FBC Residential Applies
FBC Residential (FBC-R) applies to detached one- and two-family dwellings and townhouses not more than three stories in height.
This includes single-family homes, duplexes, and townhouses. FBC-R is based on the International Residential Code (IRC) with Florida-specific amendments. For most single-family home projects in Florida, FBC-R is the applicable code.
When FBC Building Applies
FBC Building (FBC-B) applies to all buildings not covered by FBC-R, including: multi-family residential buildings (three or more units), commercial buildings, mixed-use buildings, and institutional buildings.
FBC-B is based on the International Building Code (IBC) with Florida-specific amendments.
Key Differences Between FBC-R and FBC-B
The key differences between FBC-R and FBC-B include: occupancy classifications (FBC-B uses IBC occupancy classifications; FBC-R does not), fire protection requirements (FBC-B has more stringent fire protection requirements for larger buildings), accessibility requirements (FBC-B requires ADA compliance; FBC-R does not for single-family homes), and structural design methods (FBC-B references ASCE 7 for all loads; FBC-R has prescriptive wind and seismic provisions for simple structures).
