Legal Basement Apartment Requirements
If you're planning a basement renovation and want to create a legal basement apartment in Hamilton, it's essential to understand the requirements. A standard renovation permit is just the beginning — turning a basement into a separate, rentable dwelling involves meeting several additional safety and building code standards.
A legal basement suite must include key features such as:
A fire-rated separation and fireproof door between units
Proper egress windows for emergency exits
Minimum ceiling height requirements
Correct insulation and drywall thickness for fire and sound separation
Independent heating and ventilation systems (in some cases)
At Chermark Renovations, we specialize in building code-compliant legal basement apartments. We handle everything from design and layout to permits and inspections, ensuring your new space meets all Ontario Building Code requirements for second units.

The Important Role a Skilled Pro for a Basement Renovation
Thinking of including a bathroom in your basement renovation?
Adding a basement bathroom can greatly enhance functionality and resale value, but it requires careful planning — especially when it comes to plumbing.
If your basement already has roughed-in plumbing, you’re in a great position to include a bathroom with minimal disruption. However, if no rough-ins exist, installing a new bathroom will likely require cutting into the concrete slab to install proper drainage and connect to existing plumbing lines.
This kind of work isn’t just about breaking concrete — it involves knowledge of drainage slopes, venting, waterproofing, and code compliance. A basement bathroom must be done right the first time to avoid costly issues down the road. That’s why it’s essential to work with experienced, licensed professionals.
At Chermark Renovations, we bring that expertise. Our team works closely with qualified plumbing contractors to ensure your bathroom is not only functional and up to code but also seamlessly integrated into the rest of your renovation. From permit requirements to final finishes, we handle every step with care and precision — so you can enjoy your new space with total confidence.
