A legal secondary suite requires: minimum ceiling height (typically 6'5" clear), proper egress windows in bedrooms, fire separation between units, separate smoke/CO detectors, adequate natural light, and often a separate entrance. We handle all permit applications and inspections.

Yes—we can lower the basement floor through a process called underpinning or bench footings. This involves excavating below the existing foundation and pouring new concrete. It's a significant project but gives you full ceiling height.

We assess the source first—groundwater, condensation, or leaks. Solutions include exterior waterproofing, interior drainage systems, sump pumps, vapour barriers, and proper insulation. We address moisture before finishing any walls.

For basic finishing (framing, drywall, flooring) without plumbing or major electrical, you may not need a permit. However, adding a bathroom, bedroom, or secondary suite requires permits. We recommend permits for any significant work—it protects your investment and resale value.

Yes—if you have access to the main drain (which most basements do). We can add full bathrooms with shower/tub, or powder rooms. If the drain is above floor level, we install a macerating pump system.

Basic finishing runs $40-$60 per square foot ($30,000-$50,000 for a typical basement). Adding a bathroom adds $15,000-$25,000. A full legal secondary suite ranges from $80,000-$150,000 depending on scope and existing conditions.
