Quick answer: You can sell a Markham home with an open building permit, but you should not treat the permit as a harmless administrative detail. Confirm exactly what is open, identify any missing inspections or documents, involve the City of Markham and your real-estate lawyer early, and give buyers a clear written record. Resolving the permit before listing is usually the cleanest path; when that is not practical, price, timing, conditions and disclosure need to reflect the remaining risk.
An open permit often appears after a finished basement, structural alteration, deck, addition, plumbing change or other renovation. The physical work may look complete while the municipal file is still waiting for an inspection, revised drawing, professional letter or deficiency correction. That gap matters because buyers, lawyers, lenders and insurers may ask who will complete the process and pay for any work that the City requires.

What does “open building permit” mean?
A building permit authorizes specified construction or demolition. An “open” permit generally means the municipal process has not been finalized. It does not automatically prove the work is unsafe, illegal or incomplete. It does mean the City’s record does not yet show that every required step has been accepted.
Common causes include a final inspection that was never requested, an inspection that identified deficiencies, missing engineering or architectural documentation, work that changed from the approved drawings, or a project that was abandoned. Unpermitted work is a related but different problem: there may be no permit file at all for work that required one.
The City of Markham’s building permit process, reviewed October 9, 2026, says permits are required before many construction, demolition and renovation projects. Its examples include creating rooms in a basement, installing an accessory apartment, adding new plumbing piping and replacing an exterior wall or cladding. The list is not exhaustive, so sellers should confirm their own project with Building Standards rather than guessing from the scope of work.
Why an open permit can complicate a Markham sale
An open permit creates uncertainty. A buyer cannot tell from the renovation’s appearance alone whether required inspections occurred, whether the work matches approved plans, or whether additional construction will be required. That uncertainty may lead to a longer due-diligence condition, a holdback request, a lower offer, or a demand that the seller close the permit before completion.
Ontario’s Building Code Act, 1992, current when reviewed October 9, 2026, authorizes inspectors to inspect buildings and sites for compliance and to issue orders directing compliance. The same statute addresses occupancy requirements and compliance with orders. These are reasons to determine the actual file status—not reasons to assume that every open permit will result in an order.
Disclosure also requires care. RECO’s material-facts guidance, effective December 1, 2023 and reviewed October 9, 2026, specifically identifies renovations and whether required permits were obtained as information that may be material, depending on the transaction. RECO also explains that legal disclosure duties depend on the facts and case law. A seller should obtain legal advice about what must be disclosed and how it should be documented; a marketing description is not a substitute for that advice.
A seven-step pre-listing plan
1. Search the municipal record before buyers do
Start with the City of Markham’s ePLAN public search. The City directs users to the Public Building Permit Search for permit status. Search the exact municipal address and record the permit number, project description, issue date and displayed status. Do not rely only on a contractor’s invoice or a previous owner’s statement.
If the public result is unclear, ask Building Standards what record or service request is appropriate. Markham’s building-permit page, reviewed October 9, 2026, links to a compliance report, certificate of completion, inspection requests and access to permit drawings. The City says that building service requests moved to the ePLAN portal, so confirm the current submission method when you apply.
2. Match the permit to the work in the house
Collect the approved drawings, permit card, inspection reports, change notices, engineer or architect letters, contractor agreements, receipts and warranties. Compare the approved scope with what was actually built. Look for obvious differences in walls, plumbing fixtures, windows, exits, stairs, decks and structural elements. This is document reconciliation, not a homeowner’s code inspection.
If drawings are missing, use Markham’s request process for access to permit drawings. If the permit belongs to a prior owner or contractor, ask the City how the current owner can obtain access and request inspections. Markham’s ePLAN registration guidance says an owner with an open permit can contact Building Standards to request ePLAN access.
3. Ask what is required to finalize the file
Ask the City for the remaining inspection stages, documents and known deficiencies. Keep the answer in writing where possible. “Open” could mean one missed final inspection; it could also involve concealed work, deviations from the plans or professional review. The correct next step depends on the specific permit record.
Do not open walls, remove finishes or begin corrective work solely on a buyer’s suggestion. First confirm requirements with the City and, where appropriate, a qualified designer, engineer, electrician, plumber or contractor. Electrical work may also involve the Electrical Safety Authority, which is separate from a municipal building permit.
4. Book inspections early
Markham provides an online inspection-request process. Schedule inspections before photography and offer dates if possible. If the inspector identifies deficiencies, obtain a written scope, realistic quotations and a schedule. Avoid promising a completion date until the municipality and required professionals have confirmed the pathway.
5. Build a clean seller document package
- permit-search result and permit number;
- approved drawings and revisions;
- inspection results and correspondence;
- professional letters, invoices and transferable warranties;
- confirmation of final status or certificate, when issued; and
- a chronology that distinguishes facts from estimates or planned work.
A tidy package helps the seller’s lawyer and real-estate representative describe the issue consistently. It also prevents an accidental claim such as “fully permitted” when the only evidence is that a permit was issued. Issuance, inspection and completion are different milestones.
6. Coordinate the listing and the agreement of purchase and sale
Ask your real-estate lawyer to review the permit status before an offer arrives. If the file cannot be finalized before listing, the agreement may need precise terms addressing access, further inspections, responsibility for repairs, closing timing, document delivery or a negotiated holdback. Those provisions are transaction-specific and should be drafted or reviewed by a lawyer.
Your listing strategy should also reflect buyer risk. A resolved file can support confidence in the renovation. An unresolved file may narrow the buyer pool or affect financing and insurance conversations. Do not assume that an “as-is” clause eliminates every disclosure or closing issue.
7. Update the marketing when the status changes
If the permit closes during the listing, update the brokerage file and buyer materials promptly. Replace verbal assurances with the City’s documentation. If deficiencies remain, describe the known status accurately and let qualified professionals explain technical implications.
Should you repair first, sell as-is or wait?
The answer depends on four practical questions: How clear is the City’s remaining scope? Can the work be inspected without destructive investigation? Is there enough time before the planned move? How much uncertainty will the target buyer pool tolerate?
| Situation | Likely strategy to discuss | Main risk to plan for |
|---|---|---|
| Only a documented final inspection appears outstanding | Request the inspection early and try to close before listing | Unexpected deficiencies may still be found |
| Work differs from approved drawings | Get City and qualified design advice before repair or revised submission | Redesign, reconstruction and timing |
| Work is concealed and inspection history is incomplete | Budget for professional review and possible investigative access | Cost cannot be estimated from appearance alone |
| Sale must proceed before resolution | Use careful disclosure, realistic pricing and lawyer-reviewed terms | Smaller buyer pool, conditions, holdback or closing delay |
Illustrative example: A Markham seller discovers that a basement-renovation permit is still open because the final plumbing and building inspections are not recorded. The seller gathers the approved plans, obtains ePLAN access and asks the City what remains. If the inspections pass, the file may be finalized with minimal disruption. If a bathroom location differs from the approved drawing, the seller may need revised documentation or corrective work. The point of checking early is to replace a vague risk with a defined process. This example is hypothetical; costs and outcomes vary by property.
Questions Markham sellers often ask
Can a home be listed while a permit is open?
Yes, a listing can proceed, but that does not settle the buyer’s, lender’s, insurer’s or lawyer’s concerns. The remaining work and the sale documents need a property-specific plan.
Does an open permit mean the renovation failed inspection?
Not necessarily. It may mean an inspection was never requested, documents remain outstanding, deficiencies were not cleared or the permit system has not been finalized. Obtain the actual inspection history.
Can the buyer take over the permit?
Sometimes parties negotiate a transfer of responsibility, but municipal access, the agreement terms, lender and insurer requirements, repair responsibility and any holdback must be confirmed. Do not rely on a verbal understanding.
Should I order a pre-listing home inspection?
A pre-listing home inspection can identify visible property concerns and help prepare for buyer questions, but it does not close a municipal permit or replace required City inspections.
The best time to check is before the listing calendar starts
Permit history should be part of the same early seller review as title, mortgage payout, rental contracts, repairs and disclosure. A last-minute discovery can turn a manageable municipal task into an urgent closing problem. A pre-listing check gives you time to choose between resolution, documentation or a deliberate as-is strategy.
