Commercial – Addition to Existing Structure

A commercial addition is any type of construction that expands the square footage of the building, either by going up or out. Commercial additions will need to be permitted and reviewed by Building, Planning, and General Engineering. There are three stages to permitting this type of construction.

 

Information Gathering Stage

During this stage, before any plans are drawn up by architects or engineers, it is important to think about the following items.

  1. What are the dimensions of the lot, setback requirements, height limitations, and lot coverage allowances for placing a structure on the property?
  2. Are you adding to or changing the use of the property?
    • Contact a Planner to ensure the new use is allowable in your zoning district and whether or not it needs Planning Commission approval.
    • If Planning Commission approval is required, allow 6 – 8 weeks for a decision.

Required Submittals for Permit Application Stage

  1. Site Plan
    • Site plan must be to scale

Plan Review Stage

Once your application has been accepted for intake at our Permit Center, your project will enter the Plan Review stage. Expect to hear back from Planning, Building, or Engineering concerning the following:

  • They have questions about your project
  • Part of your project may need modification

Once all parties have approved the plans for your project, your building permit will be issued and you may begin construction. Expected timeline for this stage is two weeks.
