Accessory Apartment Unit
The information below has been provided to assist in summarizing the typical requirements to obtain a building permit for an Accessory Apartment Unit within the Town of Collingwood. Additional information may be required depending on the application type and individual circumstances.
Please refer to the Accessory Apartment Unit Guide.
Planning your accessory suite:
Congratulations! You’re planning to build an accessory suite! The success of your project begins with proper planning. There are many items to take into consideration when planning an accessory suite such as budget, timelines, will you hire a Contractor or do your own renovations and how you will ensure the quality of work to ensure that you have a safe, well-built accessory unit at the end.
The purpose of this section is to help get you thinking about the various items that that may need to be considered as part of your project.
Please note that this is not an instruction manual, but rather a guide to serve as a general overview of items to be considered when contemplating the addition of an accessory unit. It is ultimately up to the owner of the property to ensure compliance with all other by-laws and other applicable regulations.
1. Ensuring zoning compliance:
- Accessory apartments are only permitted in residential zones where there is a direct municipal connection to water and sewer.
- The driveway must be able to accommodate or be expanded to accommodate 3 parking spaces. Vehicles can be parked in tandem, side by side or in a garage, if the garage meets the above noted space. You can use up to 56% of the front yard space to create accommodations for parking.
- The area that is being turned into an accessory unit must be smaller than the area of the original principal dwelling.
- Only one secondary suite is permitted per lot. If you already have a secondary suite, you cannot build another.
2. Should I and can I DIY my accessory unit?
While there is no rule or by-law that says that you must hire an installer/contractor/etc., it is a topic that needs to be approached with caution. It is important that you consider your own skills and abilities prior to deciding to undertake a DIY for your accessory unit. It is also important to note that “cutting corners” is not always the fastest way to completion as your accessory unit will have to undergo several site inspections. If it is uncovered that something was not done properly and/or to code, you will fail your site inspection and be required to repair the work to comply with Building Code and Municipal By-Laws.
Some items to consider before you undertake a DIY:
- Do you know the Ontario Building Code and the municipal By-laws under which you are going to be working under? If so, do you fully understand them and how to apply them to the construction of your unit?
- Are you able to draw/sketch/graph code compliant drawings of your proposed job that are compliant and to scale?
- Are you able to provide the detail necessary on your drawings that they are understandable?
- Do you have a background in construction and best practices associated with this level of construction building?
- Do you have the materials/tools/equipment needed to complete the project?
3. Hiring Contractors and Professionals to construct your Accessory Apartment:
Hiring a contractor can be an intimidating process if you have never done it before. When choosing a professional, it is important that although they are constructing the job, you are remaining involved by viewing the progress of the job, ensuring timelines are met by the contractor and making sure you have a signed contract with a predetermined payment schedule that is appropriate to the scope of work.
The creation of accessory units requires a niche area of specialized knowledge - regardless of whether you are constructing a new secondary suite, or you are doing upgrades to an existing suite to conform to Code.
Some items that you may want to consider are listed below. Please note that this is not a comprehensive list of all items.
- Knowledge of appropriate fire/ sound separation between units, support structure ratings
- Design of areas - there are minimum and maximum room size requirements, and specifications on egress window requirements, ceiling height, natural light requirements, etc.
- Knowledge of life-safety systems including mechanical, smoke detectors, sprinkler systems and means of egress
- HVAC requirements and ventilation
- Requirements for electrical and plumbing as well as specifications for where their mains should be located within the building
NOTE: Please note that Building Services cannot provide any consultation on design or construction outside of the permit process. It is the responsibility of the Building Department to ensure that the apartment is constructed to Building Code requirements. How you achieve the code requirements is the responsibility of the homeowner.
4. Drawings
Drawings must be submitted with your building permit. They can be completed by the property owner or you can hire a design professional who is qualified in the appropriate field to do so.
The benefits of hiring a professional can include:
- Experience and knowledge in the appropriate section of Building Code that applies to your job
- Has the knowledge to suggest alternative solutions to your ideas that may save you money in construction costs
- Reduce delays in issuing of your permit as they know the requirements that are necessary to submit
5. Permit Applications:
As a homeowner you can authorize an individual or company to apply for a permit on your behalf. If you are having a third party apply for the building permit, you are required to complete an Owner Authorization Form and submit this with your building permit application.
6. Products
Determining which products are necessary for constructing an Accessory Apartment is critical when it comes to the design, planning and ultimately the success of the construction of your project.
Below is a list of key items to consider:
Different types of fire separations for ceilings and walls
- Fire Rated Doors
- The use of a single, HVAC system (with in-duct smoke detectors) versus using a separated system for your new unit
- Different types of window sizes and options for egress
- Sound insulation between units
7. Budgeting
There are many factors when determining an appropriate budget for your project. Some items that are commonly associated with construction of Accessory Units include:
- Design fees - (for consultation and professional drawings)
- Building permit application fees
- Contractor fees
- Materials
It is not uncommon for homeowners to uncover unexpected costs as the project progresses. It is always recommended to have some funds set aside as a reserve.
Hiring a professional will likely seem like a more expensive option at the forefront of the project. However, when you hire the right professional, this can save you a significant amount of money in the long run. It is advisable to have more than one quote done on your project. Make sure you protect yourself by having a signed contract and a predetermined payment schedule.
8. Landlord Costs
It is important to understand that when you rent out your accessory unit there a few costs, some of which are recurring monthly payments, that will offset your monthly rental income being received. Some of the items to consider are:
- Increase in insurance premiums
- Property management fees
- Increased utility costs
- Increase to property taxes
- Loss of rent due to nonpayment of rent by the Tenant
- Damage repairs due to neglectful tenants
- Turnover costs - general cleaning and updating when one tenant moves out and another moves in
- Eviction costs and court fees
- Vacancies
9. Required Building Permits
A building permit gives legal permission for construction, demolition, renovating of a property. Failure to obtain a permit can result in a stop work order, legal recourse and/or having to remove completed work.
New Secondary Suites:
A Building Permit is required
Existing Secondary Suites:
If your secondary suite existed prior to July 14, 1994 and has continually operated:
- You can apply to have your secondary suite registered. To do so, you will be required to have a site inspection done by the Fire Department. The results of this will determine if a building permit may be required to alter your pre-existing suite. Please keep in mind that in order to apply under this section of code, you will be required to submit proof to support that the secondary suite has been in existence and in continuous operation. An example of this would be a signed affidavit by a previous owner, rent receipts dating back to this time, or a prior real estate listing stating the secondary suite existed.
If your secondary suite existed after July 14, 1994 a building permit will be required.
- Buildings older than 5 years are reviewed under part 11 of the Ontario Building Code to provide relief from new build requirements.
- Once you have passed your final inspection, your accessory unit will be registered by the Town of Collingwood.

The Ontario Building Code turnaround timeframes for the first review of a complete application:
Complete Applications 10 Business Days
Incomplete Applications >15 Business Days
Factors Delaying Permit Processing Time
- Zoning review is completed by the Planning Services Division which is a required Applicable Law. This generally adds an additional 3-5 business days to permit processing time.
- Additional review may be necessary if revisions are requested by your Building Inspector due to incomplete, non-compliant, or unclear drawings.
- Incomplete drawings typically cause the majority of all delays in receiving your building permit. When planning your project, you should consider allocating additional time that may be required for yourself or your designer to revise drawings, and the Building Inspector to review your revised drawings for compliance. This could add several weeks or more depending on availability and complexity.
Sentence 1.3.1.3.(1) of Division C of the Ontario Building Code (the Code) requires that where an application for a permit meets the requirements of a complete application as set out in Sentence 1.3.1.3.(5) of Division C, a decision to issue or refuse (with written reasons) such permit shall be made within times prescribed by the Code.
