The city has contracted with B&F Construction Code Services, Inc. to conduct building permit reviews and construction inspections. The Building Code is established to ensure public safety, health and welfare insofar as they are affected by building construction through structural strength, adequate means of ingress and egress, sanitary equipment, lights, ventilation, fire safety, and to secure safety to life and property.

The Wilmington Building Department would like to take this opportunity to remind residents of several important sections of the Building Code:

  • Obtain a building permit (if you are unsure if a permit is required, please call the city hall and ask for the building department). Some of the activities that do not require a building permit: landscaping, exterior painting and interior painting and paneling, repair or replacement of fixed appliances.

  • Display the building permit placard so it is visible from the street at all times.

  • Ensure contractors are registered with the city. Make sure your contractors are insured (including workers’ compensation).

  • Schedule inspections as necessary: don’t proceed with additional work until completed work has been inspected. Follow the link provided to schedule your inspection… https://www.constructioncodes.com/inspections
