Legal Basement Finishing in Brampton —
Build a Suite That Pays for Itself
A legal basement suite is one of the smartest investments a GTA homeowner can make. JBD Starr manages the entire process — from permit applications through to the final city inspection — across Brampton, Mississauga, Oakville, Milton, Ajax, and the GTA.
The Renovation That Pays You Back
A finished basement that meets Ontario Building Code requirements can be rented lawfully as a secondary suite — generating consistent monthly rental income that can offset a significant portion of your mortgage.
Beyond income, a legal suite adds appraised value to your home, makes it more attractive to buyers, and qualifies for insurance as a registered secondary dwelling.
JBD Starr handles every step — permits, framing, electrical, plumbing, fire separation, HVAC, flooring, kitchen, bathroom, and the final city inspection.
