This comprehensive code comprises all building, plumbing, mechanical, fuel gas and electrical requirements for one- and two-family dwellings and townhouses up to three stories. 

The IRC contains many important changes such as:

  • An updated seismic map reflects the most conservative Seismic Design Category (SDC) based on any soil type and 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 interconnection of smoke alarms in existing areas has been deleted.
  • New girder/header tables have been revised to incorporate the use of #2 Southern Pine in lieu of #1 Southern Pine.
  • New tables address alternative wood stud heights and the required number of full height studs in high wind areas.

    2018 IRC Code

    Joe K. | Jun 23rd 2019

    If you are in a professional industry tied to code of any kind, and are looking for an an online dealer selling legitimate digital copies, look no further. CODEBOOK DOWNLOAD was quick to answer all of my email inquiries and the post-purchase downloaded file was completely legitimate and functional (as described). Super quick response time regarding download too! If you have been scammed by other online sites in the past (not fun) worry no more. I will certainly continue to shop CODEBOOK DOWNLOAD in the future for all of my update needs. Thanks CD!

    Low Priced

    By law I have to have it with me on job sites, but it's usually pretty overpriced. Especially considering how often they are updated and it must be replaced. In this day and age, having access to a PDF version seems as though it would be a more cost effective and functional solution. CANNOT BEAT the price here!
