New Construction And Rehabilitation Development Review Process Step-by-Step Guide

The Development Review Process Step-by-Step Guide summarizes the 14 key steps to obtaining all permits and approvals needed to construct or improve a residential building in conformance with local and state policies and regulations. All projects that are required by law to obtain a permit or other approval from the City must be reviewed by the City before construction can proceed. This involves project review by multiple City of Wilmington staff and other government agencies. The project applicant pays for the costs of this review process through the payment of permit and inspection fees. Click here for a step-by-step guide to Wilmington’s Development Review Process. (Please note that this guide sets out the steps for a typical new residential construction project and the process may vary depending upon the details of your specific project.)
