Scarborough Renovation Contractor · Reformity Inc.Basement & Home Renovations in Scarborough
Scarborough basement projects run from finishing the lower level of a post-war bungalow in Wexford or Clairlea to adding a second suite in a 1970s or '80s house in Agincourt, Malvern or L'Amoreaux. Toronto doesn't require a permit for a simple finish, but one is needed as soon as the work installs or modifies plumbing or heating, adds or removes walls or other structure, underpins, adds a basement entrance or creates a second unit. We draw the floor plans and sections and file the application before framing starts.

A floor plan of the finished space: rooms, the bedroom egress window, bathroom, smoke and CO alarms, and the wall build-up. Finishing a basement usually needs a building permit, and this is the drawing the application is built on.
Renovations permits in Scarborough
Finishing a basement with plumbing, heating or structural changes, or adding a second suite, needs a Toronto building permit; for a second suite the City asks for a site plan, fully dimensioned floor plans for each level and cross sections. Reformity prepares the drawings and handles the application.

Basement permits
Finishing a basement needs a Toronto building permit if the work installs or modifies plumbing or heating, makes structural or material changes such as adding or removing walls, excavates or underpins, adds a basement entrance or creates a second suite. A finish with none of those needs no permit.

City of Toronto: multiplex housingSecond & third units
