Building Permits in Mississauga

Residential permit drawings and full application management for homeowners and contractors across the City of Mississauga. We handle the ePlans portal, the pre-screen process, and the examiner correspondence so you do not have to.

Mississauga Building Permits — From ePlans Submission to Approved Permit

Mississauga is the third-largest city in Ontario and one of the busiest residential permit markets in the GTA. The city processes thousands of residential permit applications each year through its ePlans digital portal — a system that is efficient when used correctly and frustrating when it is not. Formatting errors, incomplete uploads, and missing supporting documents can bounce your application back before it reaches an examiner.

GTA Permits has submitted residential building permit applications to the City of Mississauga for years. We know the ePlans submission workflow, the pre-screen review process, the Applicable Law Form that trips up first-time applicants, and the specific drawing standards that Mississauga examiners expect. We prepare every Mississauga submission to clear the pre-screen on the first pass.

What You Need to Know About Building Permits in Mississauga

Submission Portal

ePlans Digital Portal

All building permit applications in Mississauga must be submitted through the ePlans online system. The process works in stages: you create an account, submit a permit request with the administration fee, upload drawings, and await pre-screen review before examination begins.

Zoning Bylaw

Zoning Bylaw 0225-2007

Mississauga’s primary zoning instrument governs land use, setbacks, lot coverage, and building heights across the city. The Applicable Law Form — a Mississauga-specific document — must accompany every permit application.

What Makes Mississauga Unique

Mississauga requires an Applicable Law Form with every building permit application — a document that identifies all applicable provincial and municipal approvals. Missing or incorrectly completed, it triggers an automatic pre-screen rejection.
