If you have a basement suite on your property, you need to apply for a development permit before July 13th. There can only be three suites within a 50 metre radius surrounding the property in the neighbourhood. There can also only be two side by side in a neighbourhood. Any property owner can be exempt from those stipulations if they apply with the proper paper work before the date deadline.
Basement suites can only be included in a single detached home. The living area must have a bedroom, bathroom and kitchen. There are also rules on the size and the parking requirements needed for each home to be given the go ahead.
You can contact the city if you need to get your permit sorted. You can get details on what the requirements are on the city of Grande Prairie website.
