What is “affordable rent”? |

These are the maximum rates we’re using for this program. The rental rates are updated annually with the next updated expected in the fall. |
Do I need a building permit for an ARU? |
Yes. You need a building permit for all new ARUs or to legalize existing units. Your ARU must meet all applicable building and fire codes. A step by step guide is provided for developing an ARU. |
Can I apply if I am currently building or just built an ARU? |
Yes, if the ARU is still under construction and an occupancy permit has not yet been issued. However, only eligible costs incurred after receiving a letter of intent with conditional approval for the ARU incentive program from the city of Burlington will be eligible. |
How do I know if my ARU can be legalized? |
Contact our staff at buildingpermits@burlington.ca. We can help you figure out if your ARU complies with the Ontario Building Code, our zoning bylaws and other regulations. They can also check if building and occupancy permits were issued. If permits are missing, they can help you understand what you need to do to legalize your ARU. |
Are appliances or land costs eligible? |
No. Household appliances, land costs and non-ARU-related expenses are not eligible. Eligible expenses are outlined in the Council approved Affordable Rental Housing Community Improvement Plan. |
How long do I have to build and rent out my ARU? |
|
What are program deadlines? |
Funding is first-come, first-served and subject to availability so it’s a good idea to submit all applications as soon as you can. Your applications must be submitted, approved and building permit(s) issued before Oct. 1, 2025. |
Can I build more than one ARU? |
Yes. City of Burlington Zoning allows you to build up to three ARUs in addition to your main home on your property. The program incentives are for each eligible ARU, up to three ARUs. |
Can family members live in the ARU? |
Yes. Family members can occupy the ARU. Just make sure the unit is legal and meets our affordability and occupancy conditions as outlined in your agreement with the City. |
Are short-term rentals allowed? |
No. Short-term rentals, such as ‘Airbnb’, are not permitted. If you offer your ARU as a short-term rental property, this will breach your funding agreement. |
What happens if I die, sell the property or want to use the ARU for other purposes before the end of the 10-year agreement term? |
If the ARU is no longer owned by you or you decide to use it for other purposes, you may have to repay your funding plus administrative fees |
Can these incentives be combined with other programs? |
Yes. This program can be combined with other incentive programs, such as:
