A lot of homeowners in the GTA think permits are optional. “It’s just a small renovation.” “Nobody’s going to check.” “The last owner did it without one.”
We get it. Permits cost money and take time. But here’s the thing: skipping them can cost you way more later.
When Do You Actually Need a Permit?
In Toronto, you need a building permit for most structural or system changes. That includes:
You need a permit for:
- Removing or moving walls (even non-load-bearing ones sometimes)
- Adding or changing windows or doors
- Building a deck over 2 feet high
- Adding a basement apartment or secondary suite
- Electrical work beyond simple fixture swaps
- Plumbing changes (moving drains, adding fixtures)
- HVAC system changes
- Exterior stairs or basement walkouts
- Finishing a basement
- Building an addition
You usually don’t need a permit for:
- Painting
- Flooring (unless you’re changing floor levels)
- Cabinet replacement (same layout)
- Countertop replacement
- Fixture swaps (same location)
- Minor repairs
When in doubt, call 311 or check Toronto’s building permit info online. It’s free to ask.
The Basement Entrance Problem
This one comes up constantly. Homeowners want to add a separate entrance to their basement, maybe to rent it out or just for convenience.
Here’s where people get in trouble: many basement entrances in the GTA were done without permits. Exterior stairs, walkouts, separate doors. They look fine, but they’re not legal.
Why does this matter?
-
Insurance - If something happens (fire, flood, injury), your insurance company can deny the claim if unpermitted work is involved.
-
Selling your home - Buyers do inspections. Good inspectors catch unpermitted work. This kills deals or forces you to fix things fast at a discount.
-
City enforcement - If the city finds out (complaint from a neighbor, other inspection), they can make you remove it or bring it up to code. That’s expensive.
-
Safety - Building codes exist for a reason. Proper egress, fire separation, structural support. Unpermitted work often skips these.
What Happens If You Get Caught?
The City of Toronto can:
- Issue a stop-work order
- Fine you (fines can be significant)
- Require you to get a permit after the fact (which means opening up walls so inspectors can see the work)
- In extreme cases, require you to remove the unpermitted work entirely
Getting a permit after work is done is called “legalizing” the work. It’s more expensive and complicated than just getting the permit first.
Secondary Suites (Basement Apartments)
Ontario changed rules a few years back to make it easier to add secondary suites. But “easier” doesn’t mean “no permits.”
If you want to legally rent your basement, you need:
- Building permit for the construction
- Fire separation between units
- Separate entrance (properly permitted)
- Proper egress windows
- Smoke and CO detectors
- Electrical panel capacity
- Proper ceiling height (at least 1.95m)
- Zoning compliance
Many basement apartments in Toronto are technically illegal. They were built without permits, don’t have proper fire separation, or don’t meet ceiling height requirements.

We document everything. When you sell your home, you’ll have records showing the work was done properly and permitted.
The Real Cost of Skipping Permits
Let’s say you add a basement walkout without a permit. You save maybe $500-1000 in permit fees and some hassle.
Now let’s say you sell your home 5 years later. The buyer’s inspector flags the unpermitted entrance. The buyer asks for $15,000 off the price, or they walk.
Or let’s say there’s a fire. Insurance investigates and finds unpermitted electrical work. Claim denied. You’re on the hook for everything.
The permit fees are not where you want to save money.
Questions to Ask Your Contractor
Before you hire anyone for work that might need a permit:
- Will this work require a permit?
- Who pulls the permit - you or me?
- Is the permit cost included in your quote?
- What happens if the inspection fails?
- Can I see permits you’ve pulled for similar projects?
A good contractor won’t blink at these questions. A contractor who suggests skipping permits to “save you money” is a red flag.
