Mississauga Renovation Contractor · Reformity Inc.Basement & Home Renovations in Mississauga
Mississauga renovations tend to follow the age of the house: kitchens and bathrooms in Rathwood's 1960s and '70s homes and in Meadowvale and Erin Mills, and basement finishing in the newer houses of Churchill Meadows, Lisgar and East Credit. Finishing a basement into living space needs a City building permit, and if it creates a second unit, the City refunds the building permit fee once the unit is built and inspected. We draw the floor plan the permit asks for, marking which walls stay, come out or go in.

Renovations permits in Mississauga
Finishing a basement, adding a second unit or relocating plumbing fixtures needs a Mississauga building permit, a side-door entrance or walkout also needs lot-grading approval, and a second unit must be registered; Reformity prepares the floor plan and site plan the City asks for and handles the applications.

Basements & second units
A building permit is needed to finish a basement into living space, create a basement apartment, dig out for more headroom, or add a below-grade entrance or walkout. A second unit must also be registered with the City (there's no fee), and building permit fees are refunded for new or legalized additional residential units.
City of Mississauga: when a permit is requiredSecond & third units

Not to replace cabinets or swap a sink, toilet, tub or shower in the same spot; the City lists those as permit-free. Adding, removing or relocating a plumbing fixture, adding or enlarging a window or door, or other interior alterations do need a building permit; the City's guidance is that altering a home from its approved plans needs one.
