Basement Remodelling Key Facts
- A finished basement adds 300–1,000 sq ft of liveable space without expanding your footprint.

💡 What this means for you: The legislation that once made basement suites complicated has been largely removed. If your lot qualifies, FranklinBuilt will guide you through every step to make it happen legally and efficiently.
Ontario’s ARU legislation now permits most Niagara properties to include a legal basement suite. You’re already allowed — you just need the right builder to make it happen.
The Canada Mortgage and Housing Corporation (CMHC) Secondary Suite Loan Program offers up to $40,000 at 2% interest to help finance a legal basement suite — and it can be combined with mortgage refinancing.

Basement Remodelling FAQ: Niagara Region
At FranklinBuilt, we believe every square foot of your home deserves to be lived in fully. Whether you are finishing an open-concept family room in St. Catharines, converting an unfinished basement into a legal rental suite in Niagara Falls, or creating a dedicated home office in Pelham, our team brings deep local expertise to every phase of the process. We understand Ontario Building Code requirements, municipal permit processes, and the structural realities of homes across the Niagara Region — ensuring a smooth, transparent renovation from the first site assessment to the final inspection.
We’ve compiled these FAQs to help you navigate your building journey with confidence.
Do I need a permit to finish my basement in Ontario?
Yes, in most cases. Any structural changes, new electrical, or plumbing work requires permits. FranklinBuilt coordinates all permit applications and inspections as part of our service.
Can my basement be converted into a legal rental suite?
Yes — provided it meets Ontario Building Code and local municipal requirements for egress windows, ceiling height, ventilation, and separate entrances. We assess your space and advise on what's required to achieve legal suite status.
How long does a basement remodel take?
Timelines vary based on scope. A standard basement finish typically takes 6–12 weeks. We provide a detailed project schedule before work begins so you always know what to expect.
How do you handle moisture and water issues before finishing?
We assess and address any existing moisture concerns before beginning any finishing work. Proper waterproofing and drainage solutions are built into our process to protect your investment long-term.
Can a finished basement add value to my home?
Absolutely. A professionally finished basement is one of the highest-return renovations you can make in the Niagara market. It adds functional living space, improves energy efficiency, and is a compelling feature for future buyers — particularly when finished to a legal suite standard.
How is FranklinBuilt different from other basement contractors in Niagara?
Many contractors specialize in a single trade — framing, electrical, or finishing. FranklinBuilt manages the entire project under one roof, with a dedicated project manager coordinating every trade, permit, and inspection. You get one point of contact, consistent quality standards, and a finished result that reflects a cohesive vision — not a patchwork of disconnected subcontractors.
