Are AAVs legal in Kentucky?

[arkanos]

I'm remodeling a bathroom and am having trouble determining if air admittance valves are legal in Kentucky. If so, it would save me a ton of work running the sink vent (I'm moving the sink). The only thing I can find are some very dated articles/forum posts indicating they aren't legal and some lawsuits issued by Studor trying to make them legal.

If I've correctly interpreted the website of the people trying to sell me an AAV, it appears that Kentucky has adopted the IRC statewide and the IRC condones properly installed AAVs?

http://dhbc.ky.gov/documents/PlumbingCodeChanges2020JMFedits061620.pdf talks of changes. No mention of IPC.

I did not find indication that KY allows AAVs, but I could have missed it.

We have to go city by city for acceptability. They're approved statewide in washington state, but restricted jurisdiction by jurisdiction.

I finally got ahold of the state codes department who indicated they are not allowed.
