Richmond Hill Renovation Contractor · Reformity Inc.Basement & Home Renovations in Richmond Hill
Renovation work in Richmond Hill tends to follow the age of the house: older homes around the Village Core and Mill Pond are often due for new kitchens and bathrooms, while newer subdivision homes, in Oak Ridges and elsewhere, more often have an unfinished basement waiting. Finishing one needs a building permit here, and the City's basement checklist asks for full-height insulation on the foundation walls, down to within 200 mm of the floor, wherever existing insulation is altered or missing. We build that into the drawings from the start.

Renovations permits in Richmond Hill
Finishing a basement in Richmond Hill needs a building permit with scaled floor plans showing room uses, plumbing fixtures, window and door sizes and smoke and CO alarms; for an additional residential unit the City's list adds stamped or sealed drawings and mechanical drawings with heat-loss and heat-gain calculations, and electrical work needs a separate ESA permit; Reformity prepares the drawings, coordinates the sealed set and handles the building permit application.

Richmond Hill Renovations FAQ
Quick answers.
Not just to replace cabinets: installing kitchen or bathroom cupboards is on the City's no-permit list. Altering plumbing or HVAC, or a structural change like removing a load-bearing wall, does need one, and we prepare the drawings and apply.
