Obtain counsel immediately. This is a complicated matter that you could not possibly be adequately handled by a non-lawyer. There are some immediate problems for you that may be overcome, e.g. that you may or may not have standing to challenge the search because the residence was not yours, but there is a new vase out of the U.S. Supreme Court that may change that for you. Many of us offer free consultations. www.taubcriminaldefense.com

It sounds like the police may have confused your garage with the garage that was the subject of the warrant. If so there may be a motion to suppress whatever was found in your garage. There may be other issues as well. You say you have an offer from the DA but I don't see how that is possible without your having an attorney. If you do have one you should be discussing this with him/her, not with us.
Interesting situation. Not sure about this answer without further research, but there may be a good faith exception to the service of the warrant if the police honestly believed they had the right address when they served the search warrant. If you could show that they intentionally or negligent served the warrant at the wrong address, then there might be a motion to suppress. Ask your public defender because ultimately, you have an attorney and without knowing all the facts and information, we are purely speculating.
