You’re ready to start your renovation. The design looks great, your contractor is lined up, and you’re eager to get the job done. But there’s one question many Calgary homeowners forget to ask: Do I need a permit for this?
The short answer? Probably.
And if you skip this step, it could cost you more than just time—it could cost you fines, insurance headaches, or even impact your home’s resale value.
At Nero Contracting, we handle all permit applications for our clients, but if you’re planning or exploring your own renovation, here’s what you need to know.
What Kinds of Renovations Require a Permit in Calgary?
In general, if your project involves structural changes, plumbing, electrical, or exterior modifications, you’ll likely need a permit.
Here are some common projects that do require City of Calgary permits:
-
Moving or removing load-bearing walls
-
Adding or changing windows and doors (especially if altering openings)
-
Kitchen renovations involving new plumbing or wiring
-
Basement developments
-
Building a deck, garage, or secondary suite
-
Major electrical or HVAC upgrades
Cosmetic updates like painting, replacing cabinets, flooring, or light fixtures typically don’t require permits—unless they affect underlying systems.
Why Permits Matter
Permits exist to ensure your renovation is safe, up to code, and legally documented. They’re not just red tape—they protect you as a homeowner.
If you ever sell your home, unpermitted work can delay the sale, lower your home’s value, or force you to undo expensive renovations. Insurance companies may also refuse claims if damage is linked to unapproved work.
We’ve seen homeowners in Calgary spend thousands correcting “under the radar” renovations that could have been handled right the first time with a permit.
Who Handles the Permit Process?
When you work with a professional contractor like Nero Contracting, we manage the entire permitting process for you. We deal directly with the City of Calgary, submit the drawings, coordinate inspections, and make sure everything’s approved before work begins.
If you’re hiring a contractor who tells you a permit “probably isn’t needed,” and you’re unsure—that’s your sign to ask more questions or get a second opinion.
How Long Do Permits Take?
Permit timelines can vary. In Calgary, simple interior permits may be approved in a few days, while larger projects—like additions or legal basement suites—can take a few weeks or more.
It’s always wise to build permit time into your overall renovation schedule. A well-planned project factors in paperwork, inspections, and approvals before a single wall is touched.
