Basement Finishing
Hamilton

Typically $50 to $120 per square foot for a full permit-pulled finish covering framing, insulation, drywall, electrical, plumbing rough-in, flooring, and trim. A standard 600 sq ft basement runs $30,000 to $70,000 for a legal suite finish, with cost driven by suite complexity, ceiling height, bathroom count, and finish level.

Yes, always. A finished basement without a permit can't be legally rented, drags down resale value, and can be flagged for removal by a future buyer's lender. We pull that permit as part of every project we run.

A legal basement apartment needs a building permit, a minimum 1950mm (6'5") ceiling height, egress windows in every sleeping room, smoke and CO detectors, fire separation from the main dwelling, a separate entrance, and adequate ventilation. Every legal suite we design meets all of those OBC requirements from the outset.

A standard legal suite typically takes 8 to 14 weeks from permit issuance: roughly 1 week for framing, 2 weeks for mechanical and electrical rough-in, 2 weeks for insulation and drywall, 1 week for flooring and trim, 1 to 2 weeks for fixtures and finishes, and 1 to 2 weeks for inspections and permit close.

Ontario Building Code requires a minimum finished ceiling height of 1950mm - roughly 6'5" - in habitable basement rooms, measured after all framing, insulation, and drywall are in. A lot of Hamilton basements sitting under 7 feet of raw headroom need underpinning before finishing becomes viable at all.

Yes - we coordinate the full project, from underpinning or lowering through waterproofing, floor replacement, and finishing. Running the whole scope under one fixed-price contract avoids the coordination problems that show up when separate contractors hand off between structural and finish phases. One point of accountability, from the first dig to the last door hung.
