Additions (Commercial / Industrial)

Commercial additions may include:

• Expanding an existing building footprint
• Adding new floor area or mezzanines
• Structural modifications to support expansion
• Exterior changes that impact site layout or building size

1.Do You Need a Development Permit First?

You may need to obtain a Development Permit when planning to build an Addition to an existing commercial or industrial building. 

A Development Permit is typically required if your project involves:

• Increasing the size or footprint of a building
• Changes to site layout, parking, or access
• Changes that may impact setbacks, height, or lot coverage

If your addition changes how the site functions or looks, a Development Permit is likely required.

If you are unsure, or would like to set up a Pre-Planning meeting, please contact the Development and Planning department.
