Planning to replace windows in your Cary home? One of the first questions people ask is whether they need a permit.
The good news is that most window replacements in Cary do not need one. But there are exceptions, and your HOA may have its own rules.
What the Town of Cary Says
According to the Town of Cary’s permit FAQ:
- No permit is required to replace windows and doors in existing openings.
- A permit is required for new windows and skylights in new or modified openings.
Rules can change, so it is always smart to confirm with the Town before a big project.
When You Probably Need a Permit
| Project | Permit Likely? |
|---|---|
| Same-size window in the same opening | No |
| Making an opening bigger or smaller | Yes |
| Adding a brand-new window | Yes |
| Adding a skylight | Yes |
| Turning a flat window into a bay or bow window | Often, since the opening and framing change |
Don’t Forget Your HOA
A lot of Cary neighborhoods have homeowners associations. Places like Preston, Lochmere, Amberly, and MacGregor Downs each have their own rules.
Even when the Town does not need a permit, your HOA may want to approve:
- Frame color, especially if you want to switch from white to tan, bronze, or black
- Grid patterns, so the front of your home matches the neighborhood
- Window style changes, like swapping a double-hung for a casement
- Exterior trim changes
Approval can take a few weeks. Since custom windows usually take 3 to 4 weeks to arrive anyway, it is easy to work both timelines together.
A Simple Checklist Before You Start
- Confirm your openings stay the same size. If not, plan for a permit.
- Read your HOA’s architectural guidelines. Look for rules on windows, colors, and grids.
- Submit an HOA request if needed. Include the window style, color, and grid pattern.
- Get a written proposal that lists every window and option.
- Schedule the install once approvals are in.
What Cary Homes Usually Need
Many Cary homes were built in the 1980s through the 2000s. A lot of them still have their original builder windows. After 20 to 30 years, those often have fogged glass, worn balances, and drafts.
