Maximize Your Space with a Legal Basement
At Vertex Construction Group, we help homeowners unlock the full potential of their property with professionally built legal basements. Whether you’re looking to create extra living space for your family or generate rental income, a legal basement is a smart and valuable investment. We handle every aspect of the project, ensuring it meets all legal and safety requirements as outlined by local building codes.
With our expertise, your basement becomes a fully functional and code-approved extension of your home.
Code-Compliant Construction You Can Trust
Building a legal basement requires strict adherence to municipal regulations, including fire safety, egress windows, ceiling heights, soundproofing, and separate entrances. Our team is well-versed in all Ontario Building Code standards and works closely with local inspectors to ensure full compliance. We take care of drawings, permits, and inspections so you don’t have to worry about a thing.
You can trust us to build a safe, legal, and worry-free basement space from start to finish.


Designed for Comfort and Functionality
A legal basement should be just as comfortable and functional as any other part of your home. That’s why we focus on creating well-insulated, properly ventilated, and beautifully finished spaces. Whether it’s a basement apartment, guest suite, or entertainment area, we work with you to design a layout that meets your goals and provides long-term usability.
Our design approach balances style, efficiency, and smart use of space to meet your specific needs.
