What is a Change of Use Permit?
A change of use permit is official authorization from a municipality allowing a property owner to change the property's intended or legal use.
Why Change of Use Permits Matter in Real Estate
In Canadian real estate, change of use permits ensure properties comply with zoning, building codes, and safety regulations when usage changes.
Examples:
- Converting an office into residential units
- Turning a retail store into a restaurant
- Redeveloping industrial space for community use
Obtaining a change of use permit helps property owners avoid fines, legal action, and operational issues.
