Welcome, my name is XXXXX XXXXX I will do my best to help you with your issueUnless you live in a very rural area with no code enforcement, you would need permits to construct a new garage.
Would you possibly know the permits I would need? Being as there is no electrical or plumbing involved.
Then you would probably only need a building permit. If this is on the property where you live you should be able to pull the permit yourself or if you're having a contractor build the new garage it's best to have the contractor pull the permit
The contractor I have requires me to pull the permit. Thank you for your time and answers.
