Legal Basement Renovations Done Right
Turning your basement into a legal living space is one of the smartest ways to maximize your home’s value, increase usable square footage, and even generate rental income. But creating a legal basement apartment or secondary suite isn’t just about adding walls and finishes—it requires deep knowledge of local bylaws, building codes, fire safety, egress requirements, and permit approvals.
At 905 Reno, we specialize in legal basement renovations across the Greater Toronto Area. Whether you’re planning to create a rental unit, a private suite for family, or a high-end entertainment area, we handle every part of the process—from design and permits to full construction—with compliance, craftsmanship, and care.
What Makes a Basement “Legal” in Ontario?
A legal basement unit—also called a secondary suite or legal apartment—is a self-contained living space that meets strict requirements set out by your local municipality and the Ontario Building Code.
These requirements often include:
-
Minimum ceiling height
-
Proper-sized egress windows
-
Fire and sound separation between units
-
Smoke and carbon monoxide detectors
-
Independent heating and ventilation
-
A private kitchen and bathroom
-
In many cases, a separate entrance
Achieving compliance requires precise planning, structural updates, and city approval. That’s where 905 Reno comes in. We’ve guided dozens of homeowners through the legal basement process—handling everything from design and permits to final inspections and approvals.
Your Basement, Your Way—But Legal
Whether you’re creating a basement rental unit or designing a cozy family retreat, the final space should reflect your needs and lifestyle. We work with you to develop a plan that balances creativity with code compliance, so your basement doesn’t just check boxes—it becomes a beautiful, livable part of your home.
Some homeowners choose to include features like:
A stylish open-concept living/dining space
Modern kitchen with full appliances
Private bedroom with large windows
Laundry room (shared or private)
Soundproofed ceilings and fire-rated insulation
Custom lighting and built-in storage
Our goal is to make your basement feel just as comfortable and high-quality as the rest of your home—whether it’s for renters or personal use.
