Before going to that difficult work, I'd suggest removing the HW line to the faucet and see if you can get any water flow through the line itself. (Use a bucket...) That will tell you if the obstruction is further upstream or if it might be in the faucet itself.
Even though new, there's plenty of chances for construction debris to clog the line or the faucet. Shouldn't happen but it is frequently reported here.
If it's in the faucet you might be able to back-flow (or back-blow) it out towards the input side. If not, you may have to disassemble and see where it is. Catch everything that comes out in a bucket or in the sink itself so you'll know when you have caught the culprit!
