Basement Renovation · Mississauga
Basement renovation
in Mississauga.
Permit included.
Suburban Mississauga homes often come with deep, unfinished basements — ready for a legal suite, luxury rec room, or home office. CNB delivers the finish with Peel Region permits handled in-house.
Why CNB in Mississauga
One crew. Fixed price.
Permits sorted.
Mississauga has its own Building Division at 300 City Centre Drive. This is NOT the City of Toronto — different application system, different plan examiners, different permit fees ($1,595+HST typical). Legal suites also require a Second Unit Licence from the City ($350/yr) — CNB registers the unit for you. We manage the full Mississauga permit process: you don't deal with the city at all.
