The IRC is a prescriptive-oriented (specification) code with some examples of performance code language. It has been said that the IRC is the complete cookbook for residential construction.



The International Residential Code (IRC) was created to serve as a complete, comprehensive code regulating the construction of single-family houses, two-family houses (duplexes) and buildings consisting of three or more townhouse units.




R101.2 SCOPE

The provisions of the IRC shall apply to:

Construction Repair

Alteration Equipment

Movement Use and Occupancy

Enlargement Location

Replacement Removal and Demolition

of detached one and two family dwellings and multiple single-family dwellings (townhouses) not more than 3 stories in height with a separate means of egress and their accessory structures not more than 3 stories in height.

1. More than 6 feet above grade plane

2. More than 12 feet above the finished ground level at any point


THREE STORY…..


R325.6 HABITABLE ATTIC 2018
