Do You Need a Permit to Install New or Replacement Windows?

Are you planning to replace your windows? You might need a building permit depending on the extent of the work involved. Although a permit is not always required, it’s a critical component when it is.

When planning a window replacement, ensure you understand local zoning laws and building codes that may impact the work you can do on your home. Below, the window installation experts at Renewal By Andersen show you how to determine whether you need a permit.

Do You Need a Permit to Install New Windows?

Yes, you need a permit if you’re installing brand-new windows where your home didn’t have any before. If you want to install new windows in an existing location, it depends on your location and the extent of the work needed. 

Different states and counties have differing requirements for construction and renovation. However, as a rule of thumb, minor work involving the replacement of a single pane or sash, an inset pane or movable window parts generally doesn’t require a permit. 

Window replacement can be as simple as replacing existing windows with “inserts” fitted directly into the previous window’s frame. A permit is unnecessary since this task doesn’t require structural changes or sash removal.

You will likely need a permit if the window frame needs to be replaced or the structure changed.

Do You Need a Permit for Replacement Windows on Long Island?

Whether you are replacing one existing window, a single patio door or all the windows in your home and outbuildings, you usually don’t require a permit as long as you meet both requirements below:

• A licensed replacement window dealer or certified contractor installs your new fixtures
• Your project doesn’t require structural changes or additional construction. For example, you don’t have to enlarge the opening to accommodate the replacement window units or move the electric wiring. Instead, your window replacement project only involves installing a unit into an existing frame or replacing the movable parts of an existing window unit.

A complete window replacement is different, as it involves removing the sashes and frames. The opening may also have to undergo alterations, such as an expansion, which is a structural modification. The “permit system” ensures planned projects conform to the New York State Uniform Fire Prevention and Building Code requirements and protect the public from potential hazards like fire or inadequate egress options. 

When hiring an outside contractor to install new windows, call the local zoning and planning or permit office. Before the contractor starts the project, verify that they have permits or are eligible to install your new fixtures without applying for a permit.

Reputable contractors won’t take offense when a homeowner asks for proof they are licensed and insured and have the permit in hand before starting a job.

When Do You Need a Window Replacement Permit?

You’ll need a permit to replace a window for any of the following tasks:

• Making structural changes to your home
• Enlarging existing window openings
• Expanding a window opening horizontally
• Creating new window openings
• Switching to a new window style
• Replacing the entire window

You must also obtain an electrical permit if the replacement or installation will involve electrical work.

Do You Need a Permit to Install New Windows in an Old House?

When updating an older home built before 1978, the Environmental Protection Agency (EPA) requires contractors to perform a lead test. Even if the contractor is only replacing one window, the test is necessary to ensure there is no lead paint on or around the windows. 

If the lead test returns positive, only an EPA-CERTIFIED installer can legally do the upgrade because they must follow strict protocol for “cleanup and containment.” If any construction is required, the homeowners or contractor must purchase a permit.

Another instance where you may need a permit involves updating windows in rooms that don’t offer adequate egress options. Most local neighborhoods have building code requirements based on the International Residential Codes (IRC) that cover window size in all bedrooms. 

Why Do You Need a Permit?

There are legitimate reasons why new windows and sliding patio doors require permits. Here are some of these reasons.

• Energy efficiency: Local building codes dictate that the frames must be structurally sound. Moreover, the window seals must be durable enough to prevent drafts and energy loss, which can cause comfort issues and increase energy bills.
• Aesthetics: Local building codes also require your windows to match your home’s architectural style. This ensures your home’s uniformity and cohesion with the rest of the neighborhood.
• Structural safety: For window replacements that involve changes to the opening, the inspectors would have to check the framing modifications to ensure they are structurally sound. They may also have to look at your waterproofing and flashing details to ensure the window won’t leak.
• Egress: Windows installed in bedrooms may have egress requirements. They should be big enough to allow a family to escape and for firefighters and rescue personnel to enter in case of fire.  
• Building code adherence: Local authorities enforce building codes to ensure the safety of residents and visitors. By securing a permit, you can rest easy knowing your replacement windows meet the local building codes and regulations.
• Tempering requirements: Tempered glass is required in certain areas of the house, such as windows near doors, the floor or the bathroom. In the event of window breakage, tempered glass shatters instead of forming shards that can lead to injuries.
• Local requirements: Your home could be located in a neighborhood where homes must meet certain aesthetic requirements, such as traditional window styles and color palettes.

Who Is Responsible for Obtaining the Permit?

In general, the homeowner is directly responsible for obtaining a permit for window replacement, but many window companies can take care of this on your behalf. 

Permit applications can be difficult for homeowners since they often don’t know what information to include or how to complete the application properly. If you don’t want to deal with the whole process of applying for a permit, discuss this with your contractor. 

In some instances, the service is already part of a package. In other cases, businesses charge extra for this service. Regardless of the arrangement you prefer, communicate this to your contractor.

Permit applications may take several days, depending on the availability of an inspector. If you submit your application when an inspector is available in the office, it’s possible to get approval on the same day. To be safe, allot enough time for the permit application so that it won’t cause delays in your project.

How Do You Apply for a Permit?

If your window replacement requires a permit, you’ll be responsible for obtaining it and ensuring the work complies with all regulations. You will need to submit the application and pay the fees before the project can begin. It helps to hire a professional contractor who can handle all the building permits and ensure that your project’s completion adheres to regulatory standards.

The requirements for a permit to replace your windows vary depending on the location. In New Jersey, a construction permit application packet is available online that you can download and print. Some other states may require physical copies.

Along with the other documents required, you should submit the forms to the building department as soon as possible. Your application may take several days to be processed. The sooner you apply for and obtain your permit, the sooner you can get started on your project.

What Happens If You Replace Windows Without a Permit?

If you don’t acquire a building permit before replacing a window, it could lead to several problems, including:

• Contractor problems: A legitimate contractor would not allow installations without a permit, as it could cost them their license.
• Compliance issues: If the installation is found to be not up to code, it could get torn down and reinstalled, either at the contractor’s expense or yours.
• Time delays: A reputable window contractor will secure the necessary permits, which can delay the process if you don’t have a permit already.
• Questionable safety: Failure to obtain a permit means that your plan hasn’t been checked by building authorities, so you don’t know if your new windows meet the minimum safety standards. 
• Sale problems: If you plan on selling your home eventually, having no permit could cause you problems.

Applying for a permit for window replacement will add to your preparations and expenses. But if you want your window replacement project to go more smoothly and ensure the best results, it’s worth taking these extra steps for your peace of mind.
