How long does a basement renovation take?
A typical basement renovation in Ottawa takes 4-8 weeks for standard finishing. Secondary dwelling units and legal rental conversions take 8-14 weeks due to additional requirements like separate entrances, enhanced fire separation, and additional inspections required by the Ontario Building Code.
What is a secondary dwelling unit?
A secondary dwelling unit (also called an accessory dwelling unit or in-law suite) is a self-contained living space within your home. In Ottawa, these units must meet specific building code requirements including separate entrances, fire separation, and independent heating. They are an excellent way to add rental income or accommodate family members.
