When Do You Need a Permit to Replace Windows in Greensboro?

The Short Answer

In Greensboro, you don’t need a permit for basic window replacements. If you’re simply replacing a few windows with new ones of the same size and in the same location (no changes to the wall or structure) then you’re probably in the clear.

But there are three situations where a permit is required:

1. You change the size of the window opening (either larger or smaller).
2. You add or modify an egress window, such as one in a basement or bedroom.
3. Your total project cost exceeds $15,000, even if there’s no structural change.

So, if you’re just swapping out the living room windows? Probably no permit. If you’re upgrading every window in your home and hitting that cost threshold? You’ll want to check in with the city.

Where the Rules Come From

Permit requirements come straight from the City of Greensboro and Guilford County building codes, based on North Carolina law. Depending on where your home is located, you’ll follow either the city’s requirements or the county’s guidelines. If you live in unincorporated areas just outside Greensboro, Guilford County is the authority.

To verify your property’s jurisdiction and whether a permit is needed, visit the City of Greensboro Residential Construction Guidelines or the Guilford County Inspections Portal.

The $15,000 Rule: When Cost Triggers a Permit

According to North Carolina General Statute §160D-1110, any non-structural residential work over $15,000 requires a permit. Most homeowners replacing a handful of windows won’t hit this threshold. But if you’re installing high-performance windows throughout your home, it’s definitely possible. 

If You Live Just Outside Greensboro City Limits

Live in Oak Ridge, Summerfield, or another spot just outside city limits? You’re probably under Guilford County’s building rules. The rules are mostly the same as Greensboro’s, but permit applications go through the county instead of the city.

HOAs and Historic Homes

Some neighborhoods will have their own approval processes. Homeowners’ associations might also require architectural review. These are separate from city permits but still important. Zen Windows can help you navigate these additional requirements.

What Happens If You Replace Windows Without a Permit?

It might seem harmless, but skipping a required permit can have real consequences. If the city or county finds out that structural work was done without a permit, they can issue a stop-work order, levy fines, or require you to redo parts of the job. Worse yet, it could create problems during a future home sale. Unpermitted work often gets flagged during home inspections, and that can impact your appraisal or scare off potential buyers.

Is This a Common Problem in Greensboro?

Not regularly, but it does happen—especially when full-home renovations or significant window alterations are involved. Homeowners often assume window upgrades are minor, but if size changes or egress windows are added, code compliance becomes a safety issue.

Greensboro Permit FAQs

How Do I Double Check My Jurisdiction & Permit Requirements?

To confirm whether you’re under city or county jurisdiction and whether your job requires a permit:

1. Visit Greensboro’s residential portal.
2. Search your address.
3. Review the “Building Permits” section for residential guidelines.

What Counts as “Resizing” a Window?

If you’re planning to widen a small window, install a taller unit, or turn an existing window into a sliding glass door, that’s considered structural work. The same goes for removing or relocating a window entirely. Anything that changes the wall framing or affects the home’s structure requires a permit.

What If I Already Did Work Without a Permit?

You may be able to apply for a retroactive permit, but the city might still require inspection and, potentially, corrections. That’s why it’s always better to handle permitting upfront.
