General planning information. Confirm local requirements with your municipality and qualified professionals.
Reno Rise is focused on Toronto basements, but it also receives enquiries from across the GTA. This page covers what homeowners in Ajax (Durham Region) should keep in mind when planning a basement project.
Homes in many Ajax subdivisions date from roughly the 1980s to the 2000s, so basements are often newer builds. That can make finishing more straightforward, but moisture and ceiling height should still be confirmed rather than assumed.
Confirm the Basics First
- Measure ceiling height and check for moisture before choosing a scope.
- Ask your municipality’s building department which work needs a permit. Zoning and permit rules are set locally and Toronto rules do not apply outside Toronto.
- If you are considering a rental or in-law unit, read our legal secondary suite guide for the general considerations, then confirm local rules with your municipality.
- Ask each professional about credentials, insurance, references and permit responsibility.
For the general process, see basement renovation planning, basement finishing and interior waterproofing.
Request a Basement Assessment
Share a few details about your basement and your plans. Reno Rise reviews what you send and matches your project with the contractor best suited to the work. This does not confirm an appointment, a quote or an approval.
