The first thing that you need to do with respect to the commercial lease that you have written about and the automatic renewal provision is to carefully read the written lease. The reason is that its terms and conditions control the obligations owed to you by the landlord and vice versa in the absence of conflicting state law.If there is a provision in the lease regarding automatic renewal that you signed, then you are obligated under its terms. If you have missed the time period to end the automatic renewal, then you should have a face to face meeting with your landlord to see if there is some way you can end the lease after the passage of three (3) years.If he/she is unwilling to do so, I suggest that you consult with an attorney that practices commercial landlord tenant law.
