Rapid ADU Deployment Program: One-Window Service

Building an Accessory Dwelling Unit (ADU) takes time and investment, but the Town of Collingwood is here to assist landowners throughout the process. If you have any ADU-related questions, please email ADU@collingwood.ca.

Here are some suggested steps to follow when planning your ADU(s):

Step 1: Understanding Planning and Building Rules

Learn about what is allowed and what is not allowed. Some rules in the Town's Zoning By-Law no longer apply to fully municipally serviced residential parcels due to  Bill 23: The More Homes Built Faster Act, but some rules still apply. Learn more about the planning and building rules here

This is also a good time to familiarize yourself with the Town's ADU building requirements.  

Step 2: Calculate the Cost of Your ADU

Once you know if your property can accommodate one or two ADUs, it's time to estimate the building costs. For basement or garage conversions and conventionally constructed detached ADUs, it's helpful to gather estimates for the cost per square foot. For pre-fabricated or modular detached units, it's best to contact the manufacturer directly for pricing. A qualified designer can also provide approximate figures for the overall construction, utility connections, and foundation design.

Step 3: Explore financing options

Now that you have an estimate for your ADU project, it's time to determine how to finance it. This is where lenders can be helpful. Reach out to your mortgage lender, bank, local credit union, or other financial specialist to explore loan options and get pre-approved for your desired loan amount. Some lenders offer specialized ADU financing programs, so be sure to inquire about any specific programs they have that can help maximize your budget.

Step 4: Find a qualified designer

With a rough budget in mind and financing options considered, it's time to delve into the project. It is strongly recommended to work with a design professional such as an architect, professional engineer, or a Building Code-qualified designer to create comprehensive and accurate drawings that comply with the Building Code, Collingwood Zoning By-Law, and any other relevant standards or requirements. You are strongly encouraged to contact ADU@collingwood.ca to ensure that you meet all Town requirements and avoid unexpected issues. 

Feature: Detached Garage ADU Conversion

Curious about what you can do on your property? In this example, an old detached garage was transformed into workforce housing and office space. The property owner preserved the existing concrete foundation slab and walls to minimize the environmental impact of new materials. The new two-story ADU includes living and home office spaces and is conveniently located near the downtown core, offering the tenant improved walkability and quality of life.

"I hope this example will encourage others in the community to pursue similar social impact infill projects that can help alleviate the Town's current housing crisis." - Property Owner
