2018 IRC SOFTCOVER
The 2018 IRC is a REQUIRED CODEBOOK for 2018, B1, M1, P1, and E1 Residential Building Inspector Exams.
This comprehensive code compiles all building, plumbing, mechanical, fuel gas, and electrical requirements for non-commercial one- and two-family dwellings in one convenient code. The regulations cover dwellings and townhouses up to three stories.
The 2018 IRC® contains many important changes, including:
- An updated seismic map reflects the most conservative Seismic Design Category (SDC) based on any soil type. A new map reflects less conservative SDCs when Site Class A, B, or D is applicable.
- The townhouse separation provisions now include options for using two separate fire-resistant-rated walls or a common wall.
- An emergency escape and rescue opening is no longer required in basement sleeping rooms where the dwelling has an automatic fire sprinkler system, and the basement has a second means of egress or an emergency escape opening.
- The exemption for the interconnection of smoke alarms in existing areas has been deleted.
- New girder/header tables have been revised to incorporate #2 Southern Pine instead of #1 Southern Pine.
- New tables address alternative wood stud heights and the required number of full height studs in high wind areas.
