If you’re considering turning your basement into a legal living space in Ontario, there are several steps and costs involved. Legalizing a basement apartment requires you to follow strict regulations and obtain the necessary permits.


 

Step 1: Obtain a Building Permit

The time it takes to process and issue permits varies, with an average of 13 weeks for new residential buildings, 7 weeks for residential alterations, and 10 weeks for secondary units. Keep in mind these are estimates, and actual times may vary.
