What constitutes an illegal basement in Canada?

In Canada, regulations are in place to ensure the safety of citizens and maintain high living standards. Basement construction must adhere to these standards to ensure complete safety. Regulations are constantly updated and therefore regular inspections are recommended to ensure that basements comply with current rules.

How to Legalize an illegal basement in Canada?

In Canada, a basement is considered as the ‘second unit suite’ of a house, and it is subject to specific zoning codes that vary from one city to another. For instance, the legal requirements for basements in Ontario may differ from those in Calgary, British Columbia, and other provinces. Therefore, before legalizing a basement, it is crucial to ensure that it meets the zoning code requirements of the particular city where the property is located. Here are the basic requirements to legalize a basement in Ontario. These requirements should be followed when building a basement in Canada:

  • Legalizing a basement in Canada involves meeting minimum requirements to ensure safety and comfort of occupants and compliance with zoning code.
  • Minimum space requirement of 145 square feet ensures sufficient living area that meets zoning code requirements.
  • Ceiling height of at least 1.95 meters or 6.4 feet ensures comfortable living space and enough headroom for occupants.
  • Proper windows that occupy at least 5% of living area and 2.5% of floor area allow for proper ventilation, natural lighting, and easy access in case of an emergency.
  • Proper electrical system, including heating and cooling, and insulated electrical wiring approved by Electrical Safety Authority ensures safety and compliance with zoning code.
  • Proper sink in kitchen and other areas of basement apartment with hot and cold water supply ensures hygienic and comfortable living space.
  • Dedicated laundry area that meets zoning code requirements ensures safe laundry activities without the risk of electrical hazards or other dangers.
  • At least two exits in basement allow occupants to escape in case of an emergency and meet safety requirements of zoning code.
  • At least 30 minutes of fire separation between basement and main unit ensures safety of occupants in case of a fire and compliance with zoning code.
  • Meeting these minimum requirements is necessary for legalizing a basement and ensuring safety and comfort of occupants, as well as compliance with the zoning code.

Perks of a legalized basement in Canada:

Legalized basements have become a popular choice for homeowners due to the numerous advantages they offer.

Source of income: 

Firstly, it provides an additional source of income by renting out the space. In a world where inflation is rising, it is becoming increasingly difficult to purchase a home outright. Hence, many people resort to mortgage payments, and having a legalized basement is a great way to supplement their income.

However, it is important to note that to rent out a basement, it needs to be inspected and permitted by the relevant authorities. By obtaining the necessary permits, the homeowner can rest assured that the rental agreement is legitimate and legally binding.

Increased Space for family

Another benefit of a legalized basement is that it can provide additional space for the family. This extra space can be utilized to accommodate guests or as a work or study area. By having a designated space within the home, homeowners can reduce their expenses by avoiding the need to rent a separate space for these purposes.

No Stress

Furthermore, having a non legal basement can cause a great deal of stress for homeowners. In Canada, specific laws  regarding basements are stringent, and non-compliance can lead to the authorities taking action. This can result in costly fines and even forced eviction from the property. Thus, it is always advisable to follow the necessary procedures to legalize the basement suite and apartments.

Increase value of the house

Lastly, having a basement apartment can increase the overall value of the property. Similar to the difference in price between a one-story and a two-story house, the presence of a basement can significantly increase the price of a property. By investing in a legalized basement, homeowners can increase the overall worth of their home and reap the benefits in the long run.

The advantages of having a legalized basement are numerous. From providing an extra source of income to increasing the value of the property, it is an investment that can yield great returns for homeowners. It is always recommended to follow the proper legal procedures to avoid unnecessary stress and fines.
