Why You Need a Permit to Install Replacement Windows

Replacing your windows seems like an easy enough task. So, you might be wondering if you need a permit. While it may not seem like it, there are actually some important building codes that have to be met before installing new windows, especially if you have decided to change the size or location.

Before you shop around for new windows, here’s what you need to know:

Permit to Install Replacement Windows

Why Is It Necessary to Obtain a Permit?

This is the most common question. Most homeowners are under the false impression that replacing their windows is not a big deal as it does not alter the structural integrity of your home and that inspections and obtaining permits are not necessary.

The truth is, your windows are an integral part of your home, and securing the proper permits is necessary to ensure that you and your family are safe. Whether you are upgrading to energy-efficient windows or converting an existing casement window into a sliding window, the minimum code requirements must be met.

For example, windows installed in any room that can be used as a bedroom must be large enough to allow the occupants to escape during an emergency or for rescue personnel to enter the building when disaster strikes. Another example is windows must be at least 24 inches from the floor to prevent small children from climbing over the windowsill and accidentally falling out.

Replacement windows located in a hazardous area will also require an inspection since they might need safety glazing.

These are just some of the reasons why permits are necessary, and it is understandable that these considerations are not foremost in a homeowner’s mind when shopping around for new windows. This is why it is important that you speak to experienced local professionals to ensure that you are compliant.

"This was one of the best experiences I've ever had with a company. I ordered the windows in November and was told they wouldn't be here until July. That kind of delay the new norm so I wasn't a bit upset with the timeline. I was given an early present when they called to say the windows would be in at the beginning of May. We agreed on the week of May 16th to do the installation, there were 30 windows and a sliding door to install. They arrived promptly on their scheduled install date, and got straight to work. By the end of day one, they had all the upstairs windows complete and their work was incredible. Day two came with more of the same, the crew showed up promptly, got straight to work, and when they left they had every window downstairs installed. The third day they again arrived on-time, and got to work installing the door. The door and windows are perfectly installed. The two lads that did the installation did a phenomenal job, and were friendly to boot. I would give them more business if I had any :) The service I received from the company was great. They kept me abreast of anything that was going on with my order. I appreciate my concierge, Christina, she was good at communicating timelines and getting everything scheduled."

"The two installers were great! They were polite and hard working and they cleaned up all the outside and inside. It was like they were never here. As for the windows, I love them, not only looks great, they are efficient. Now every window in my home has Renewal by Anderson."

"We had the pleasure recently of having Andersen replace all of our windows. From the very first interaction with the office personnel through the completion of the project, they have been nothing but professional. From Brian our sales rep to Christina the appointment scheduler, they were a pleasure to interact with. Installers Keith, John, and Evan were fantastic to work with. They went above and beyond to repair an area which was slightly damaged during the removal of a window...caulked and painted it. They took extra precaution to ensure the floors were covered while working inside and cleaned up each day inside and out. We love the look of our new windows and can't wait to enjoy the savings in utilities they'll provide. Thanks so much Renewal by Andersen!!"
