What information is required for a building permit?

Every building permit application is different and may require different information, depending on the scale and nature of the intended project. In some cases, it may be necessary to go through a Planning Approval process prior to the submission of a building permit application. For detailed advice about your own development plans, please contact the City’s Development Coordinator. General submission items are listed below.

Additional Residential Unit (ARU) Guide 

Ensuring everyone has a home they can afford begins with housing choice. Providing and supporting housing choice that is affordable and attainable requires a coordinated and cooperative effort including homeowners, governments at all levels, agencies, developers and not-for-profits.  When people create ARU’s, it's an investment that benefits the owner, future occupants and the community.  

There are many and diverse benefits of ARU’s:

Social

• Creates housing choice for students attending post secondary school.
• Provides a rental option that is more affordable for young adults, retirees and newcomers.  Allows people to live independently longer.  

Financial 

• Rent from tenants helps make home ownership affordable.
• Can increase property values.

Environmental

• Helps optimize the use of land and servicing infrastructure.
• Reduces greenfield development.
• Low environmental footprint reducing sprawl.

This guide has been developed to help you understand the requirements to legally create an ARU.  Let’s get started!

This guide is not intended to replace that guidance and advice from professionals. 

This guide includes information on zoning, servicing (sanitary and water) as well the other requirements you will need to complete and submit an application for building permit.  

How much does a building permit cost?

Please be advised, as of July 1, 2023, our fees have changed.   For a full break-down of relevant permit fees, see the City's Fees & Charges By-Law. 

Note: These fees are subject to change at any time, at the City’s discretion. 

What am I paying for exactly?

With a valid building permit, you are paying for peace of mind that your intended project is permitted in terms of the Ontario Building Code, the City’s Zoning By-Law, and any other relevant policies and By-laws. During the building process, one of the City’s Building Officials will visit the property to inspect the on-going work on your property during various stages of construction. 

What happens if I build without a permit?

Starting work without a building permit is a Provincial Offence under the Ontario Building Code Act and is subject to additional fee and charges as outlined in the Building By-law.

How long does it take for the City to issue a building permit?

The timeline for the City to issue a building permit will vary based on the nature of the project. It is important to submit a complete application to ensure that permit review can begin. Prescribed timelines can be found in Division C Part 1 of the Ontario Building Code.

What happens after I have received my building permit? 

Once you have paid for and received a valid building permit, you are required to commence construction on the project within 6 months of the date of permit issuance, unless express permission is granted by the Chief Building Official. 

Once the work has commenced, property owners/applicants are required to contact the Building Department to book mandatory inspections at each stage of the construction process, as regulated by the Ontario Building Code.

I want to put up a tent for an event. Does that require a permit?

If your tent (or group of tents) has an area of more than 60m², then a tent permit is required prior to erecting the tent(s). Tents larger than 225m² will also require a site review done by a qualified engineer before occupancy will be granted. For more information see our tent guide. 

How does the Zoning By-law affect construction projects?

Before you apply for a building permit, it is important to determine the zoning regulations that apply to your property. The City's Zoning By-law tells you what you can use your property for, the size and location of the building, as well as other requirements. The regulations address such matters as:

• Permitted land uses within different parts of the City
• Setbacks of buildings from property lines
• Setbacks of buildings from lands zoned 'Hazard' (ZH)
• Building heights (usually from the ground in front of the building)
• Building floor areas (can be defined as minimums or maximums)
• Lot coverage (usually a maximum percentage of the lot that may be covered by buildings)
• Accessory uses and buildings (e.g. pools and utility sheds)
• Home occupations and outside storage
• Required municipal services (water and sanitary sewer services)
• Parking requirements
• Secondary units ("accessory apartments") and converted dwellings 

For more information on the Zoning By-law, please contact the Planning Division.
