A finished basement, a rebuilt deck, a knocked-down wall between the kitchen and living room — renovations like these show up in almost every resale listing photo. What the photos don't show is whether the work was ever permitted, inspected, and formally closed with the municipality. That gap is exactly what a building permit condition in an Ontario offer is designed to catch.
If you're buying a home with visible past renovations, adding a building permit condition to your offer is one of the more practical protections your lawyer can help you put in place — well before you're contractually locked in.
Why Buyers Add a Permit Condition
Most municipal building work in Ontario — additions, structural changes, new electrical or plumbing systems, basement finishes above a certain scope, and more — requires a permit, an inspection during the work, and a final sign-off closing the permit once the work passes inspection. When that process wasn't followed, or wasn't finished, you inherit the consequences as the new owner, not the seller who did the renovation.
A permit condition gives you a window, after your offer is accepted but before it becomes binding, to confirm whether past work at the property was properly permitted and closed — and to walk away or renegotiate if it wasn't.
Open vs. Non-Compliant vs. Unpermitted Work
These terms get used loosely, but they describe different problems:
- An open permit was applied for and started, but never received a final inspection and sign-off closing it out — meaning the municipality's records still show the work as unresolved, regardless of how long ago it happened.
- Non-compliant work may have been inspected and flagged as not meeting code, without being corrected and properly closed.
- Unpermitted work was never registered with the municipality at all — no application, no inspection, no record, even though the renovation clearly happened.
All three can create the same practical problem for a buyer: a municipality can require corrective work, additional inspections, or even removal of non-compliant elements, and an open or missing permit can complicate a future sale, refinancing, or insurance claim.
What the Condition Typically Requires
A building permit condition generally gives the buyer a defined period to:
- Search the municipality's permit records for the property address, to identify any open, expired, or unclosed permits.
- Compare the permit history against the visible renovations — does the finished basement, the addition, or the rebuilt structure have a matching, closed permit?
- Request that the seller close out or correct any open or non-compliant permits before closing, or negotiate a price or holdback adjustment to account for the cost and effort of doing so after closing.
- Decide whether to waive the condition, negotiate, or walk away, based on what the search reveals.
Clearing the Condition: What Typically Happens
| Scenario | Typical path forward |
|---|---|
| No open permits found; renovations match permit history | Condition is satisfied and waived |
| Open permit found for minor, cosmetic work | Buyer and seller often negotiate — seller closes it, or price/timeline adjusts |
| Open permit for significant structural or safety work | Buyer may require the seller to resolve it before closing, or reconsider the deal |
| Unpermitted work discovered with no record at all | Higher-risk scenario; often requires legal and possibly municipal building department involvement to assess options |
Risks of Waiving This Condition
Buyers under time pressure — especially in a competitive multiple-offer situation — sometimes waive conditions, including a permit condition, to make their offer more attractive. That can be a reasonable calculated risk for a property with no visible renovations, but it's a materially different risk for a home with an obvious basement finish, addition, or major structural change and no visible paperwork to back it up. Once you waive the condition and firm up, you generally lose your ability to walk away or renegotiate based on what a later permit search reveals.
What Happens If Permits Can't Be Closed Before Closing
Sometimes a permit issue is identified but can't realistically be resolved before the scheduled closing date — municipal timelines for inspections and sign-offs aren't within either party's direct control. In that situation, buyers and sellers commonly negotiate one of a few paths: the seller escrows funds or agrees to a holdback to cover the cost of resolving the issue after closing, the closing date is extended, or the parties agree on a price adjustment reflecting the buyer taking on the risk. Your lawyer can help structure whichever approach fits your specific deal.
Frequently asked questions
How do I find out if a property has open permits?
Your lawyer can request a permit history search from the relevant municipality as part of your due diligence, typically alongside other standard closing searches.
What if the seller says the renovation was "done properly" but there's no permit on file?
Treat the verbal assurance as a starting point, not a substitute for the actual municipal record. If the permit history doesn't match what you're told, raise it in writing before you firm up.
Does every resale purchase need a building permit condition?
Not necessarily — it depends on the property's renovation history and your risk tolerance. A home with no visible past renovations carries less of this specific risk than one with an obvious addition or major interior reconfiguration.
Can I still buy a house with an open permit?
Often, yes — many open-permit issues are resolved through negotiation, a price adjustment, or a post-closing holdback rather than derailing the deal entirely. The key is knowing about it before you're contractually committed, not after.
