Commercial Additions & Renovations Services Across Ontario

(Hamilton · Stoney Creek · Niagara Falls · Waterdown · Toronto · Brampton · Oakville · Ontario)

Expanding or renovating a commercial space is a major investment—one that directly affects your business operations, staff productivity, customer experience, and compliance obligations. Unlike residential work, Commercial Additions and Renovations must meet higher safety standards, stricter building codes, fire regulations, zoning bylaws, and inspection requirements.

At ITI Permit, we provide end-to-end Commercial Additions and Renovations services across Hamilton, Stoney Creek, Niagara Falls, Waterdown, Toronto, Brampton, Oakville, and throughout Ontario. Our role is to ensure your project is professionally designed, legally approved, and executed with minimal disruption to your business.

From early planning to final approval, we manage architecture, BCIN-compliant drawings, construction permits, inspections coordination, and licensing support—so your commercial project moves forward with confidence.
