Submittal Requirements

The following list gives the submittal requirements for the most common commercial projects. If you have your plans ready for review but do not know your contractors, you need to submit a Plan Review Application in place of the Construction Permit Application. You can submit the Construction Permit Application once you know who the contractors for your project will be.
