Permits and Regulations in Hamilton

Most significant renovation projects in Hamilton require a building permit from the local municipality. Common projects that require a permit:

Structural changes (removing walls, additions, decks over 24 inches)
Electrical work (new circuits, panel upgrades, service changes)
Plumbing alterations (moving fixtures, adding bathrooms)
HVAC installation (new furnace, AC, ductwork changes)
Roofing (full replacement in some municipalities)
Fencing (depending on height and location relative to property lines)

Projects that typically do not require a permit: painting, flooring, countertop replacement, fixture swaps, landscaping (without retaining walls), and minor repairs.

Your contractor should handle all permit applications and arrange required inspections. If they suggest skipping permits, that is a red flag.
