Whether you’re looking to add value to your property, generate passive income through rental, or create a comfortable, separate living space for extended family, our team is here to make it happen—legally, safely, and beautifully.



What sets our legal basement renovation services apart is our commitment to compliance and quality. Navigating the Ontario Building Code and local municipal regulations can be daunting. That’s why we take care of everything—from zoning checks and permit applications to final inspections. We ensure your basement renovation meets all legal requirements, including minimum ceiling height, proper egress windows, fire-rated separations, HVAC systems, plumbing, insulation, and soundproofing. Every detail is carefully planned and expertly implemented.
Our process begins with an in-depth consultation where we evaluate your current basement condition and discuss your goals for the space. From there, we handle architectural drawings, structural considerations, and all permit-related documentation to save you time and stress. Once approvals are in place, we move to construction, using only premium materials and trusted techniques. Whether your project requires underpinning to increase ceiling height or simply involves finishing an existing basement, our experienced team delivers exceptional results every time.
A legal basement apartment can serve multiple purposes. Many GTA homeowners are capitalizing on the rental market by converting their basements into secondary suites. These legal units offer excellent ROI and meet increasing demand for affordable housing in cities like Toronto, Mississauga, Brampton, and beyond. Others are building private suites for aging parents, adult children, or visiting guests—combining privacy with proximity in a way that suits today’s multi-generational households.
With Maas Trust Concrete Inc., you’ll benefit from a personalized approach to design and construction. We don’t believe in cookie-cutter layouts. Every project is tailored to your home’s architecture, your lifestyle, and your long-term plans. Our craftsmen work efficiently, cleanly, and respectfully in your space, completing each phase of the job with attention to detail and pride in workmanship.
Above all, we focus on legal basement renovation that enhances both the form and function of your home—without cutting corners. We believe that creating a legal suite should be a smooth and stress-free process for homeowners. That’s why our team is always available to answer questions, provide updates, and ensure that the final result exceeds your expectations.
When you partner with Maas Trust Concrete Inc., you’re choosing a company with decades of experience, deep knowledge of GTA building codes, and a passion for quality construction.
