Turn your property into income, or create more space for family
Zero Carbon Agency helps Ontario homeowners explore secondary suites, garden units, basement apartments, garage conversions, and home additions designed for rental income, family living, or long-term property value.
At Zero Carbon Agency, we help Ontario homeowners unlock the full potential of their property by creating additional living spaces such as garden suites, garage conversions, basement apartments, and home additions.
These spaces can be used to generate rental income or provide comfortable, independent living space for family members such as parents, adult children, relatives, or guests.
Our team provides end-to-end support, helping homeowners move from early planning to permits, construction coordination, and rental-readiness.

Explore whether your project may qualify for support
To help address Canada's housing supply challenges, different funding, financing, and refinancing options may be available to homeowners who want to add secondary suites or additional housing units to their property.
Zero Carbon Agency helps homeowners understand available options in their province and explore whether their project may qualify for support.
In some cases, homeowners may be able to use refinancing or financing options to move a project forward without requiring the full project cost upfront. Because a new suite may generate rental income, some homeowners use that income to help offset financing costs while creating additional monthly cash flow.
Some announced or proposed programs have referenced support of up to $80,000, but availability, eligibility, and program status may change. Our team can help homeowners review current options.
