The secondary suite must be for a related adult over the age of 65 or living with a disability, including a grandparent, parent, child, grandchild, sibling, aunt, uncle, niece or nephew.
The secondary suite must be a self-contained housing unit that includes a separate entrance, bathroom, kitchen and sleeping area.
Additionally, the home being renovated must be inhabited or reasonably expected to be inhabited within 12 months after the end of the renovations.
Some expenses, such as the purchase of home appliances and costs for housekeeping or other services, do not qualify for the credit.
The credit was among a number of new housing affordability measures promised by the Liberals in the last election and included in the 2022 budget last April.
