Oshawa mortgage renewals and lender switches.
Oshawa distinguishes older existing second units from units created after July 1994 when explaining how to legalize their use. If an accessory apartment contributes to your income, establish the correct municipal records before a renewal switch or refinance. A unit's age is not proof of compliance.
What matters in Oshawa
- For an existing second unit created before July 1994, Oshawa directs owners to Municipal Licensing about legalizing a two-unit house. Ask the City which records apply rather than assuming the unit is grandfathered.
- Oshawa says a building permit is required to legalize second or third units created after July 1994. Keep the permit evidence and any completion records with your rental file.
- Accessory apartments remain subject to Oshawa zoning provisions. Before consolidating debt using rent-supported borrowing, confirm both the property's compliance and how the chosen lender assesses that income.
