Obtaining a Building Permit
How Long is my Permit Good For?
Your building permit is good for six months after it is issued, however, the work must continue without interruption. It may, with permission of the Commissioner, be renewed for up to 180 additional days provided that the request to extend the permit is made within the first six months. After that, if you have not started work, your permit will be considered abandoned and you will have to reapply.
