Commercial – Adding 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.
- What are the dimensions of the lot, setback requirements, height limitations, and lot coverage allowances for placing a structure on the property?
- 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

- Site plan must be to scale
- Include the dimensions of the structure
- Include accurate property line locations in relation to the proposed structure
- Parking Plan
- Could be combined with site plan

Will the footprint of the building be expanded? If yes, please submit the following, in addition to the items above:
- Vegetative Cover Plan
- Label all interior rooms and include square footage
- Exterior Lighting Plan (only if there are changes)
- Lighting plan should show the location of lights and lighting specifications
Depending of the specifics of the addition, one or more of the following plans may also need to be submitted:

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.
