Office construction is Ottawa's largest commercial construction segment, driven by government and technology tenants: Base Building vs. Tenant Improvement: When leasing office space, the landlord typically provides a 'base building' (structural shell with basic mechanical and electrical). The tenant then builds out the interior (partitions, finishes, specialized mechanical/electrical, data/telecom) according to their needs. The lease usually includes a Tenant Improvement Allowance (TIA) from th...

For most commercial construction in Ottawa, architectural drawings stamped by a licensed Ontario architect are required for building permit applications. Small interior renovations (paint, flooring, minor partitions) may not require an architect. For substantial renovations, additions, or new construction, an architect is mandatory.
Commercial renovations in Ottawa require a building permit from the City. Additional permits may include change-of-use permit, demolition permit, heritage permit (for designated buildings), sign permit, and specialty permits (Ottawa Public Health for food service, AGCO for liquor service). Your contractor manages the permit process.
