Underpinning Permit in Markham
Getting a underpinning permit in Markham means working through City of Markham Building Standards - a process with its own local zoning by-law, specific requirements, and York Region two-tier coordination, timeline expectations. PermitsHub handles every step for Markham homeowners: compliant permit drawings, zoning review, application submission, and revision management through to approval.
How we handle underpinning permits in Markham

Underpinning permit drawings prepared to City of Markham Building Standards standards (site plan, floor plans, structural details)

Application submission via Markham accepts applications through its online Permit Centre.

Proactive correspondence and revision management with City of Markham Building Standards until the permit is issued
- 5
York Region coordination where regional approvals are triggered by the project
Key considerations for Markham
Underpinning lowers the basement floor by excavating and extending the foundation - it always requires a permit.
Engineered drawings from a licensed structural engineer are required for all underpinning applications.
Neighbouring property notifications and, in some cases, party wall agreements are required.
Staged underpinning sequences and shoring plans must be shown to protect the structure during work.
Markham has its own Zoning By-law 177-96 with area-specific schedules.
