If you’re planning to build or convert basement secondary suites in Brampton, you need to follow strict legal guidelines. Whether you’re a homeowner or investor, adding a legal suite can bring significant value. It also helps meet the high demand for affordable housing. But legal compliance is essential. That’s where Archon Design Permits steps in to help.
Let’s walk you through the process of creating a legal basement unit. From design to permits, this guide covers it all.
What Is a Basement Secondary Suite?
A basement secondary suite is a self-contained unit within a single-family home. It includes a kitchen, bathroom, and sleeping space. These units offer rental income and make housing more affordable in cities like Brampton and Mississauga.
However, they must meet local zoning laws and building codes. Without legal status, you risk heavy fines and tenant issues.
Why Make It Legal?
Converting your basement legally isn’t just about avoiding penalties. Legal suites offer many benefits:
- Increased property value
- Safe, livable space for tenants
- Steady rental income
- Easier resale with approved documentation
If you’re considering building a legal basement apartment in Mississauga, similar rules apply. You’ll need accurate design plans and approved permits.
