That depends on the nature of the project. At a minimum you will need to complete a building permit application. Other documents you may need include architectural plans, product approvals, site plan, or engineering details. If you do not own the property, you will need a notarized letter from the owner allowing you to do the project, show a lease that allows you to do the project, or have the owner sign the permit application. Please call our office or come by and explain your project to us, and we can go from there.
