Q I’m replacing all the windows in my house, and they’re about the same size as the old ones. Do I need a permit for this? A Usually you do need a building permit, unless your window replacement is simply swapping out the sashes (the movable parts). Once you touch the opening itself, or replace the entire window (frame and all), you usually have to get a permit. Why are cities demanding a permit for such a simple job? Are they just ripping you off to collect fees, or
do they add some value? The building department does have some legitimate reasons to oversee window replacements. Protection, for example. The building code (remember, it’s only a “minimum” standard, not best practice) requires tempered glass in any windows near doors, near the floor, or in tubs or showers as a safety precaution. Tempered glass is stronger than normal glass and shatters rather than breaking into sharp shards to minimize possible injuries. Another serious issue
is “egress,” meaning entry and exit. Windows in bedrooms must meet egress requirements for width and height to allow you out and fire personnel in. Trust me, you don’t want to be trapped in your home in the event of a fire. And you don’t want the firefighters to be unable to get in with their bulky equipment.
Many existing homes don’t meet egress requirements in bedrooms, so make sure you double-check before ordering bedroom windows.
Cities may also do a “planning” review of window replacements to make sure the style is appropriate for your home. Fortunately, most cities prohibit ugly mill-finish aluminum, for example. If your home has “multipane” windows, some cities will require you to maintain that traditional look in order to preserve the aesthetics of the neighborhood.
Finally, if you are altering the opening, the inspectors will check to make sure your framing modifications are structurally sound. They will also inspect your waterproofing and flashing details to ensure the window does not leak.
As you can see, there are good reasons why all but the most minor window replacements require a permit. In the end, it’s for your own good.
You may be able to find the exact rules online. For San Jose’s permit processes, go to www.sanjoseca.gov/building. San Mateo County has an excellent two-page description that provides a lot of detail about window replacement rules. The guidelines will likely be similar to those in your area: www.co.sanmateo.ca.us/vgn/images/portal/cit_609/1037190311040.pdf.

January 6, 2020 by Some home improvements require a permit, which makes this a matter you must discuss with your contractor to ensure you have the right documents for your project. When it comes to window replacement, many homeowners get confused about whether or not they need to obtain a permit.
Does Window Replacement Require a Permit?
A window replacement that involves enlarging the existing opening requires a permit. The most common reasons for expanding an existing window opening are to make space for bigger windows, convert a window into a door or meet fire code or egress requirements.
You’ll need to obtain a permit for these projects since expanding the opening sideways usually involves cutting the studs on either side of the window, which can cause the wall structure to become unstable. Even the slightest horizontal enlargement requires a permit.
Who Should Obtain the Permit?
It’s the responsibility of the homeowner to obtain a permit for the installation of their replacement windows. However, the process can often be confusing, which is why many contractors offer to help. Make sure to talk about this matter with your contractor to determine who should be responsible for the task. At Renewal by Andersen®, you can count us to guide you in every step of your project.
What a window company does and doesn’t do for you says a lot about their reputation. You should think twice about hiring a contractor who pays no attention to building codes. Also, not getting a permit can cause you issues if you decide to sell your home in the future. When the new owner decides to get a home inspection, the data on the documents won’t match the structure of your home.
