What are Airspace Rights?
Airspace rights are the legal rights to control, use, or sell the space above a parcel of land, separate from the ownership of the land itself.
Why Airspace Rights Matter in Real Estate
In Canadian real estate, airspace rights can be a valuable asset in dense urban areas where vertical development potential exists.
Key facts:
- Can be sold, leased, or transferred independently
- Governed by municipal zoning and height restrictions
- Often leveraged to build upwards or develop bridges and overpasses
Understanding airspace rights allows property owners to maximize land value and development potential.
Example of Airspace Rights in Action
The developer acquired airspace rights from a neighbouring building to construct additional floors on their tower.
Key Takeaways
