2015 IRC SOFTCOVER
The 2015 IRC is a REQUIRED CODEBOOK for 2015, 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 2015 IRC® contains many important changes, including:
- Common walls separating townhouses must now be rated for 2 hours when an automatic fire sprinkler system is not installed.
- Remodeling an existing basement does not trigger the emergency escape and rescue opening requirements unless a new bedroom is created.
- Ramps that do not serve the required egress door are now permitted to have a slope not greater than 1 unit vertical in 8 units horizontal.
- Carbon monoxide alarms now require connection to the house wiring system with battery backup. A carbon monoxide alarm is required in bedrooms when there is a fuel-
- fired appliance in the bedroom or adjoining bathroom.
- Revised lumber capacities have changed the span lengths for floor joists, ceiling joists, and rafters in the IRC’s prescriptive tables.
- New sections and tables provide prescriptive methods for posts, beams, joists, and deck construction connections.
- The girder and header span tables of Chapter 5 have been moved into Chapter 6. Multi-ply and single header tables are combined. A new section describing rim board headers is added.
- If you answer sixteen or more of these free ICC B1 practice questions correctly, you are in good shape.
- However, if you miss five or more questions, get this course, you are in danger of failing your ICC B1 test.
