Additional Residential Unit Incentive Program

The Additional Residential Unit (ARU) Incentive has five incentives and grants that help property owners create alternative housing options within the city.  

Property owners that create an ARU and agree to meet the conditions of the program can get funding. The funding options include forgivable loan incentives and non-repayable grants. If you receive a forgivable loan, you do not need to repay this loan if you continue to meet the program terms for five years. 

We review and approve applications on a first-come, first-served basis while funding is available.  

1. Detached ARU Incentive  

The detached ARU incentive provides eligible property owners financial help of up to 50% of the project cost or $40,000, whichever is less.  

  • The property owner receives the funding after the occupancy of the unit in the form of a forgivable loan. 
  • The property owner will not need to repay the loan if they follow the terms of the program. 

2. Interior ARU Incentive 

The Interior ARU incentive provides eligible property owners financial help of up to 50% of the project cost or $30,000, whichever is less.  

  • The property owner receives the funding after the occupancy of the unit in the form of a forgivable loan. 
  • The property owner will not need to repay the loan if they follow the terms of the program. 

3. Accessibility ARU Grant

The accessibility ARU Grant provides a $5,000 extra funding to an ARU project that meets accessibility criteria. We encourage the development of more accessible housing options.

  • No ongoing terms or conditions associated. 
  • Funding is provided following the occupancy of the unit.
  • A property owner can combine it with the Detached or Interior ARU incentives, or they can choose to access the Accessibility ARU grant independently.

4. Rough-In Detached ARU Grant

The rough-in detached ARU grant provides $5,000 of extra funding to property owners that install rough-in servicing (i.e. water supply, sanitary sewer, and electrical supply) to accommodate a future detached ARU project.  

  • Installing rough-in services during the construction of a detached ARU can help save future costs for servicing it. 
  • The Rough-In Detached ARU grant enables property owners to create opportunities for future ARU development.  
  • The Rough-In Detached ARU Grant cannot be combined with any other incentive.

5. ARU Servicing Constraint Area Grant 

The ARU Servicing Constraint Area grant provides eligible property owners financial help of up to 50% of the construction cost or $10,000, whichever is less to upgrade an existing half inch water service.  

  • This grant enables properties that would otherwise be subject to servicing constraints to have an ARU. 
  • Funding is provided following the issuance of the occupancy permit and submission of supporting documentation. 
  • A property owner must combine it with the Detached or Interior ARU incentives.

Eligible costs are those related to the creation of the ARU. Some common costs covered: 

  • Design fees 
  • Structural modification
  • Electrical
  • Plumbing
  • Fixtures

We only forgive loans for ARU projects that have continued to meet the terms of the agreement for a five-year term. Forgiveness would occur at a rate of 20% per year of compliance with the terms of the program.

If during the five-year term, the ARU is no longer rented following the terms of the agreement, the property owner must pay the forgivable loan at a prorated rate. 

The program has an initial funding commitment of $1.25 million.

We review completed applications and respond to each within two weeks. If the project is eligible, we will send a conditional letter of commitment indicating the applicant has one year to complete and occupy the unit following the terms of the program.
