The Permit Process, Step-by-Step1. Visit or contact your local Building Department
The Building Department is responsible for the issuance of building permits for your property and is usually located within your local municipal office or Civic Centre. It is useful to speak directly with a Building Official and discuss your project to determine if the plans comply with the Ontario Building Code and the applicable by-laws. This initial contact can provide you with the resources and information necessary to make your project a success and avoid potential problems which could cost you time and money.
Submit your ApplicationPermit applications can be accessed both through our office as well as on our site. Once you have filled out your application you must ensure that the correct documentation and drawings accompany your submission. Your application can be submitted personally or by another person such as your contractor or qualified designer. It is important to keep in mind that the inspectors have up to 10 business days for a house, tent and sign permit, 15 business days for small buildings, 20 business days for large buildings and 30 business days for complex buildings to issue the permit, although depending on the levels of applications we are receiving in out office the time frame may vary. Under certain conditions, your permit can be fast tracked for an additional 25% of the permit fee.
- Reviewing the Application
The Building Official (inspector) will review the building plans and application to determine compliance with the Ontario Building Code, the municipality's by-laws, provincial regulations and other applicable agencies. If the application complies, the permit can be approved and issued by the Building Official. If the plans and application do not comply, Building Staff will notify the applicant indicating what deficiencies remain and what information or documentation will be need to gain the necessary compliance. Please ensure that the necessary information is submitted so that there are no delays in the issuing of your permit.
*The building inspector may contact you throughout the process if additional information is needed*
- Obtaining the Building Permit
Once all the necessary approvals and documentation have been received and reviewed the building inspector will contact you for pick up. The permit fees will be calculated in accordance with the project as per the Fee Schedule and will be available to be picked up and processed through the Civic Centre or your local Municipal office. You may also be required to submit a damage deposit that could cover potential damage to municipal property and ensure that required inspections are completed as it is refunded after the completion of the project. A building permit is the document granting legal permission to start construction and you must proceed accordingly to the approved Building Permits and plans. One set of the permit will remain on file, and the other set will be returned (to be kept on site during the construction process). Any proposed changes throughout the construction process must be brought to the attention of the building inspector immediately.
- Inspections & Completion
No work can start until the issuance of the building permit and the development must be completed in phases. During each major phase of construction the Building Official (Inspector) must inspect the project to ensure that the work conforms to the approved plans. A list of all the mandatory inspections and the Building inspectors phone number will be provided at this time on the permit. The person responsible for the construction project must request each inspection within 48 hours notice. If the Building Official finds that some of the work does not conform to the approved plans, he or she will advise that the situation be remedied. Once all the mandatory inspections have been completed and the Building Inspector has completed their final inspection the project is complete!
