  3. always have the approved plans and drawings on site for the building inspector (inspection may fail if plans are not on site)


You can book building inspections online. After your inspection, you can check if the inspection passed or failed and read the inspector’s notes.

Or call our inspection request line at 519-741-2761. Have your permit number ready, including your inspection codes that can be found at the bottom of your permit.

Please book your inspection(s) by 3 p.m. on the day before your inspection.

Conditional permits

A conditional permit (CP) is a permit issued under Section 8(3) of the Building Code Act at the discretion of our Chief Building Official (CBO). A CP may be issued when the applicant can show that applicable laws, including site plan approval, are forthcoming and that the approval timeframes are unreasonable and are causing unnecessary construction delays.

Find this information below:


You can apply for a CP in the cases in the accordions below.

A CP application is not a fast track to circumvent planning approvals or the time necessary for normal building code technical reviews, which ensure that public health and safety standards are being met.

Part 9 model home
Subdivision is registered or a model home agreement has been executed (see step five of the conditional permit process, submit a conditional permit application).
All other cases
  • Where subject to site plan approval under s.41 of the Planning Act, plans or drawings have been stamped ‘endorsed’ and, approval in principle (AIP) has been issued by the Director of Planning, except for a Part 9 model home.
  • Any necessary zoning, heritage, conservation authority or environmental permissions have been obtained and any appeal period has expired, or appeals have been resolved.
  • If a minor variance was necessary, then the variance must be approved by the Committee of Adjustment and all appeal periods must have lapsed and/or any appeals have been fully resolved.
  • All required applications set out in the OBC in Section “Definition of Applicable Law” have been filed, and approvals are forthcoming.

Our Chief Building Official (CBO) may refuse a CP application for any reason.

We cannot issue a CP if certain planning, heritage, conservation authority or environmental approvals are not completed. Other refusal decisions may include an objection from another approval agency, where applications have only been very recently filed or when the owner has not filed all required documents.

The CBO’s decision is final. There is no appeal available on CP decisions.

Limitations of CPs

A Conditional Permit (CP) allows an owner to lawfully start construction entirely at their own risk in some circumstances. A CP is different from a regular building permit in that it is limited by certain conditions imposed at the discretion of the Chief Building Official (CBO).

For example, if the required outstanding approvals are not obtained within the prescribed time period, if the conditional permit is revoked, any construction conducted thereunder must be removed and the site restored at the owner’s expense.

You must fully disclose to the CBO any information or uncertainty you have about an outstanding approval, to reduce the risk that the permit is revoked.


A Conditional Permit (CP) application must include a fee, as outlined in our building bylaw. The fee is not refundable. Before issuing the Conditional Permit, we will prepare an agreement that you must secure with a letter of credit or certified cheque in an amount specified by the Chief Building Official (CBO). The letter of credit may be drawn on to restore the site, if necessary. All other fees are payable in full, including normal building permit fees and applicable development charges. 

If you do not get the outstanding approvals, including building permit(s), before the conditional permit’s expiry date, you must request to extend the conditional permit. Extensions of the conditional permit expiry date incur a fee and are subject to the approval of the CBO.


To apply for a Conditional Permit (CP), you will need:

When you have the completed forms and permit fee, send us an email.

If we approve your CP request, we will prepare an agreement setting out the terms of approval and the timeframes to obtain such approvals.

To get the CP, you must: 

  • sign and return the Conditional Permit Agreement (sample agreement)
  • submit a certified cheque or an irrevocable letter of credit (LOC) for the detailed cost estimate that was approved by the CBO

The securities must be from an acceptable financial institution following our investment policy and in a form approved by us (sample letter of credit) and reference the date of the Conditional Permit Agreement and the owner listed on the Conditional Permit Agreement. 

The linked documents above are general samples only and are subject to change at the discretion of the CBO.

Conditional permit process

The Conditional Permit (CP) process is outlined below.

  1. read the entire Conditional Permit Guide
  2. if the project is eligible for a CP request, submit these documents by email:
    • written CP request that proves unreasonable delays in the construction would happen if you do not receive a CP (sample letter to the CBO)
    • detailed cost estimate (see sample)
  3. the Chief Building Official (CBO) will review the request (timing)
    • if the CBO does not support the request, we will let you know
    • if the CBO does support your request, they will consider comments from other city staff (examples: planning and engineering) or agencies for any specific conditions that need to be included in the CP
  4. building staff will let you know about any or all applicable conditions of your CP (timing)
    • if you or your authorized agent accept the conditions, proceed to step 5
    • if you or your authorized agent do not accept the conditions, the process ends
  5. submit a Conditional Permit Application and associated construction documents
  6. building staff will ask our legal staff to prepare a CP agreement
  7. legal staff will contact the applicant when the agreement is ready to sign
  8. the owner(s) and mortgagee (if applicable) sign the agreement, provide security and return the signed agreement to legal staff as soon as possible
  9. the owner or authorized agent will satisfy pre-permit issuance conditions, including paying any development charges (if applicable) and outstanding legal and permit fees
  10. when steps eight and nine are complete, including the plan review for the building permit, we issue the CP and construction can start
Process timing

Steps three and four will be completed within 15 business days.

Steps six and seven will be completed within 15 business days.
