I belong and it costs about $150 per year.
Wow, who do you have to "know" to get that price?
The advertised price is $810 members/$900 non members, and that is a yearly subscription.
We do not subscribe. It is like renting a code book. After a year, the screen goes dark. Even more fun, it is only a single seat license, meaning only one computer can access it. So not only are your renting a code book, you have to go to a specific book case and read it right there, no bringing it back to your desk.
We used to subscribe, and they would send us a disk of all the current codes. If you did not renew, you just stopped getting updates. The disk still worked, it was just not the "latest and greatest".
Latest and greatest is oversold anyway. All the referenced NFPA standards are necessarily several years behind the adoption of the model code. The 2006 I codes (still enforced by many in my region) reference 2003-2005 NFPA standards, the 2009 references 2006-2008 standards. For healthcare work, everything is based on the 2000 NFPA 101 and the even earlier standards referenced by it. As an example, 2010 NFPA 13 is only valid if an AHJ has specifically amended the model code. We are still using the last disk that they sent at the end of 2007, since it includes the 2008 NEC.
I recommend buying the electronic versions of the codes you need (13, 13r, 13d, 14, 20, etc), in the versions adopted by the AHJ, then using the free (for members) "view" of the rest of the codes. You can not cut and paste or print, but it is handy to check what has changed, or to look up an obscure standard. If you find yourself accessing a particular standard more than 3 or 4 times, probably time to buy that standard.
