A real estate agent leased me commercial property that turned out not to be commercially zoned. What do I do?

If the action has caused you financial harm you can pursue damages against the realtor. He should be insured for negligence.

If the property is not as advertised or not as agreed, they are in "breach" of that part of the contract unless they can fix the problem for you. Your local attorney can help you figure out your options and make the arrangements to ask them for compensation for your damages. Only if they refuse to pay your damages, and either terminate the contract or fix it, you will then have the option to sue them for various things.

The only advice you should take from this site is this: You need to get the help of a licensed attorney in your area who is familiar with business law.

Hire an attorney!

You should have checked.

However you may have a case to sue the agent and the landlord as they miss represented the property.

You kick yourself for not doing your due diligence.

See a Lawyer this is Fraud and you want your money back.

Actually, the real estate agent didn't lease you commercial property.

Does the lease guarantee that the property is commercially zoned? It's up to YOU to do your due diligence.

ETA: "In the lease agreement it is stated that the use of the property is for a business" So what? Not all businesses require commercial property. Mine doesn't. It's up to the tenant to ensure that the property is usable for the intended purpose. So far from what you've said, no misrepresentation was made by the agent. You simply failed to do your basic homework.

Sue.

Although to be honest, why didn't you do your own due diligence?
