Before starting construction on an addition to your building, there are several steps you will need to take to ensure your addition will be in compliance with zoning and building regulations. Your proposed addition must meet setback requirements and Zoning regulations. If your building is a landmark, in a special district, or has specialized zoning, additional approvals will be required.

Process Overview

  1. Determine Zoning

    The first step of adding onto a non-residential building is to determine if the parcel is zoned for your desired use or if there are any special development considerations for your project.

    Zoning staff will be able to tell you the zoning of the property and if there are any special conditions which will affect your project. Additions to non-residential buildings require review and approval by various City agencies through the Parking Lot / Site Plan Review process. Some of these projects will also require a special approval, such as an alteration to an existing conditional use or alteration to a PUDSIP. Zoning staff can guide you through this process. Additional information may be found by going to Land Development.

    Find out the zoning for your property.
