Scheduling an Inspection

Individuals who have become familiar with our online inspection schedule website have realized the benefits of this system, and the added features to keep you, the permit holder, apprised of permit requirements and inspection history.  

One noticeable feature is the email notification that occurs the day of your scheduled inspection at 7:00 am.  For the past year this notification along with a phone call from your Inspector have been a standard occurrence. However, starting April 26, 2021, the email notification will serve as our primary notification.  You’ll no longer receive a phone call unless the Inspector has questions regarding your specific inspection request.

Please know that this email notification will continue to contain helpful information, including the estimated time of your inspection, identify of your assigned Inspector, and also provide links to view permit/parcel information and to pay fees. 

Should you have any questions, please give us a call at (302) 395-5572.

Code Opinions

The New Castle County Inspections Section strives to provide accurate and consistent applications of the International Codes for our customers. However, from time to time an occasion will arise where we need input from the International Code Council (ICC) regarding a specific code section. In these cases, a request is sent to the ICC and a Staff Code Interpretation is provided in return. These impartial third-party decisions are receive from the ICC to assist jurisdictions in applying the code fairly and accurately. The Interpretations that we have accumulated for past and present code adoptions are listed here: Code Opinions.
