Advantages of Adding Legal Basement Apartment

A legal basement apartment is a type of secondary dwelling unit in Ottawa that you can rent out or use as a guest space. The space includes a kitchen, one or more bathrooms, bedrooms, and a living area.

Here are a few of the many advantages to creating a legal apartment in your basement:

  • Provides a private and comfortable living space for extended family to live in or stay in while visiting.
  • Increasing your home’s resale value and makes your house more attractive to potential buyers.
  • Opens up the opportunity for additional income should you choose to rent the apartment full or part time.

What’s Included in Our Legal Basement Renovation

Capital Basement Renovation will help you design and build a basement that meets all your needs, wants, and requirements. For example, we can build a legal basement apartment with a walkout, walk-up, or separate exterior entrance. Our team waterproofs basements to ensure a mould free environment and provide basement underpinning services when necessary. We also help guide through the permitting process and submit applications for you.

As experienced legal basement contractors, you can count on us to handle the following: 

  • Electrical: Our team has the required training and licenses to install all the electrical wiring in your basement. We will take care of putting in electrical sockets, light fixtures, and appliances, such as fridges and stoves.
  • Plumbing: We are qualified to install, replace, and alter your plumbing systems, water lines, and sewer systems. This allows us to build top of the line bathrooms and kitchens.
  • Emergency Exits/Egress Window: We have an in-depth knowledge and understanding of the safety regulations and building codes for the Ottawa area. This includes the size, location, and specifications for the required egress windows in a basement apartment.
  • Fireproofing System Installation: In addition to waterproofing basements, we also provide fireproofing. This includes properly ventilating the basement and installing fire alarms and carbon monoxide detectors as per building code.
  • Soundproofing: If you’re planning to rent out your basement apartment, soundproofing the area is essential. This increases the privacy for you and your renters.
  • Insulation: Insulating your basement is very important as it helps prevent mould growth, improves the comfort of the space, and reduces energy costs. We will insulate each side of your basement apartment and ensure all windows and exterior doors are sealed and weatherproof.
  • HVAC Installation: We will install a separate HVAC system for your basement apartment. This gives you and the basement occupants better temperature control.
