Window Replacement Permits: Navigating Wilmington’s Building Code Requirements and Inspection Process

Navigating Window Replacement Permits in Wilmington: Your Complete Guide to Building Code Compliance and Inspection Requirements

When planning a window replacement project in Wilmington, Delaware, understanding the permit requirements and inspection process is crucial for ensuring your project complies with local building codes. Whether you’re upgrading for energy efficiency, improving your home’s appearance, or addressing safety concerns, navigating the regulatory landscape can seem daunting. This comprehensive guide will help you understand when permits are required, what the inspection process entails, and how to ensure your project meets all necessary requirements.

Understanding When Window Replacement Permits Are Required

All construction activity including new buildings, interior and exterior improvements, alterations, and most repairs requires a permit unless the work is specifically exempted by the New Castle County Code. For window replacement specifically, you need a permit if the window replacement calls for the alteration of the wall structure or the expansion of an existing opening.

However, generally, homeowners’ permits are not required for replacement in kind. This means if you’re simply replacing windows with the same size and type in existing openings without structural modifications, you may not need a permit. The replacement window shall be permitted to be of the same operating style as the existing window or a style that provides for an equal or greater window opening area than the existing window.

Special Considerations for Egress Windows

If your window replacement involves basement or bedroom windows that serve as emergency exits, special egress requirements apply. A window must meet certain requirements to pass the state of Delaware’s egress window code. This building code ensures inhabitants have a second means of exit from a basement living space, in the event of an emergency.

Key egress window requirements include:

  • An unobstructed opening with a minimum area of 5.7 sq. ft. (This requirement drops to 5 sq. ft. for grade floor or below grade openings)
  • The height of the clear opening must be at least 24″ and the width must be at least 20″
  • The window must be openable from the inside without the use of keys, tools, or special knowledge

The Permit Application Process

Homeowners should apply for a permit only if they are doing the work themselves. If a contractor is doing the work, it is their responsibility to obtain the permit. This is an important distinction that many homeowners overlook when planning their window replacement project.

For those applying for permits themselves, having all required documents, plans, and copies ready before you come to the Department of Land Use will help expedite your visit. In most cases, this will include at least the following: a completed Building Permit Application, three (3) sets of Building Plans, and three (3) copies of your current Plot Plan.

In the Land Use Department, you will go through a permit screening process. Our staff will ensure that you have all the necessary paperwork and verify that there are no overdue taxes or fees for the property.

The Inspection Process

Once your permit is approved and work begins, several inspections may be required. Inspections required under the provisions, rules and regulations adopted by the County Council shall be made by the Department of Land Use.

For electrical work associated with window replacement, within five days of starting the work under a Delaware Homeowners permit, contact one of the Delaware-licensed inspection agencies to have the electrical work inspected. Additionally, before installing dry wall, you will need to contact one of the Delaware-licensed inspection agencies for a “rough in” inspection.

Professional contractors typically handle the inspection scheduling process. At Wilmington, we take care of all required permits and pair you with a dedicated project manager who oversees every detail from planning to completion.

Fees and Timeline Considerations

The County Council shall adopt rules and regulations providing for the charge of reasonable fees for the administration and enforcement of the New Castle County Building Code including fees for the issuance of permits, inspections and registration. Permits are valid for only one year and are not renewable, so it’s important to plan your project timeline accordingly.

For contractors, you no longer have to deal with it, especially if the contractor can do that for you. It only takes a small fee to get it done, which will be added to the total cost of your project.
