the reason that i want to frame the garage door is because i want to turn the garage into a playroom. so if the codes apply same for the house, i would like to know and the reason is that it's too expensve to pay somebody for the job and i cannot affort it so i will do it my self. I dont know what's the framing code for the spacing between every stud and I dont know if I have to modify the existing framing or if I only need to just frame it like that. Also, do i have to install foundation on the new wall? If so, how deep do I have to go? do I have to jackhammer the concrete or can i just set the foundation on the existing concrete floor? all your advises will be appreciated.

It's not at all clear what you're trying to do, so no comment is possible.

It sounds like you ae trying to frame up a garage door opening and turn it into just a wall, perhaps for extra living space? You should definitely check into local code requirements because they will likely be different for a living space than a detached building, not only for framing but for insulation, vapor barrier, etc. If the existing concrete slab is in good condition, then you should be able to frame up from that, but be aware that most garage floor are designed to slope towards the doorway, so if you want a level floor a bit more work will be required. Now would be the time, also, to rough-in for any future plumbing you may want to add.

If you're just turning the garage into a shop or a shed, then you will likely be okay following the measurements of the existing walls, assuming the garage was built to code to begin with, but please save yourself some headaches later on and check with your local authorities. They will be happy to assist you.

Aha, I get it...you are closing a garage door opening, not framing a garage door opening. You will have a few building code requirements to deal with...natural light, natural ventilation, insulation, and depending on where you live, possibly foundation, which should extend below the frost line for your locality. Often, this foundation is omitted under garage doors, and if it's not there, it may have to be installed. The studs should be the same thickness as the rest of the garage, and be spaced 16 inches on centers. No modification to the existing framing is necessary.
