Is there a standard for installing sheet rock in garages that are attached to homes. The builder told me that they don't finish sheet rock in garages the same as inside homes. My home is a new build. Sheet rock in garage is a mess.
Sheet rock in garage is a mess.
That is the standard, unless your contract specified an interior quality finish. It will be taped and mudded and possibly given a coat of paint.
The good news is that you can practice sanding and finishing and texturing drywall in your garage with no fear of messing it up.
