This is a compilation listing the codes used in each state and territory of the US. Most of the list came from the terrylove.com forum, but I also found additional info from http://www.tests.com/State-Plumbing-Codes-License.
There are two main plumbing codes used in the US: IPC (International Plumbing Code) (see also this link) and UPC (Uniform Plumbing Code) - 2009 version. It should be noted that some states use their own code but most are based on IPC or UPC precursors. There is also the NSPC (National Standard Plumbing Code) adopted by one state.


Alabama- IPC adopted by Local Governments
Alaska- UPC adopted at State level but IPC in use locally
Arizona- UPC adopted at State level but IPC in use locally
Arkansas- uses IPC
California- California Plumbing Code based on UPC (for pdf see this)
Colorado- uses IPC
Connecticut- IPC effective Statewide
D.C.- IPC effective in city
Delaware- IPC effective Statewide
Florida- IPC effective Statewide
Georgia- IPC effective Statewide (seehttp://www.plumbingpros.com/pdf/dwvents.pdf)
Guam- uses IPC

If anyone has any amendments, corrections, updated links, or additional info; please share. Hopefully this will help people to at least get an idea of what the codes are where they live. I tried to color code it to make it easier to differentiate.

Update:
Effective January 1, 2016: Louisiana no longer has its own plumbing code. Instead, it now must adhere to the rules of the 2012 version of IPC.

http://new.dhh.louisiana.gov/index.cfm/page/1523
Louisiana House Bill 1048 was signed by the Governor on June 23rd, 2014 and enacted as Act Number 836 of 2014. With an effective date of January 1st, 2016, this Act repeals the authority of the State Health Officer, acting through the Office of Public Health (OPH) of the Department of Health (DHH), to prepare and promulgate plumbing rules and regulations.

In accordance with the Act, the Louisiana State Plumbing Code [Part XIV (Plumbing) of Title 51 (State Sanitary Code) of the Louisiana Administrative Code (LAC)] will be null, void, and unenforceable on and after January 1, 2016. As required, the Louisiana State Uniform Construction Code Council (LSUCCC) will promulgate State plumbing regulations through the evaluation, adoption, and amendment of the following codes as part of the State Uniform Construction Code:

The 2012 International Building Code, Chapter 29-Plumbing Systems;
The 2012 International Residential Code, Part VII-Plumbing; and,
The 2012 International Plumbing Code.

Applicable plumbing provisions of these codes, along with state amendments thereto adopted by the LSUCCC, will become effective January 1, 2016.

The International Codes can be assessed at: http://publicecodes.cyberregs.com/icod/index.htm

Louisiana amendments were published as an Emergency Rule in the December 2015 Issue of the Louisiana Register. These amendments can be accessed at: http://www.doa.la.gov/osr/EMR/1512EMR082.pdf

Beginning on January 1st, 2016, all plumbing systems will be required to be designed in accordance with the provisions of these codes, as amended by the LSUCCC. This includes new construction, reconstruction, and the extensive alterations or repair of buildings and other structures. In accordance with the Act, LDH will no longer have enforcement authority over the new plumbing provisions that will become part of the State Uniform Construction Code. Enforcement of such will be handled in accordance with LA R.S. 40:1730.21 which requires all local municipalities and parishes in the State to enforce the State Uniform Construction Code. This includes plan review, conducting of inspections, and the issuance, denial, or revocation of permits.

In addition, the new law amends the Louisiana Building Code (which governs the design of state-owned buildings) by removing compliance with Part XIV (Plumbing) of the State Sanitary Code and replaces it with the above referenced codes, as amended by the LSUCCC. Beginning on January 1st, 2016, the Office of Facility Planning and Control of the Division of Administration will be responsible for ensuring that state-owned buildings comply with these newly adopted plumbing regulations.

I wonder if that means that AAVs can now be used again, or if they are still forbidden.
