As-Built Surveys
Across the GTA
Certified as-built surveys conducted by licensed OLS professionals on our team. Documenting the final position of your completed structure — accepted by all GTA municipalities for occupancy permits and project closeout.
What is an As-Built Survey?
Documenting Your Structure Exactly As It Was Built
What it is
An as-built survey is a certified survey conducted after construction is complete that documents the final position, dimensions, and elevations of all structures as they were actually built — compared to the original approved drawings. It confirms that your project was constructed in the correct location, at the correct grades, and within all required setbacks and property boundaries.
When you need it
As-built surveys are required by many GTA municipalities as a condition of occupancy permit approval — and are essential for project closeout documentation, lender requirements, and future reference across Toronto, Mississauga, Brampton, Markham, Vaughan, and all Greater Toronto Area municipalities.

Many GTA municipalities require a certified as-built survey before issuing an occupancy permit for a new home or building — confirming the structure was built in the correct location and within all required setbacks.
New Home Construction
Builders and homeowners constructing new homes across Toronto, Mississauga, Brampton, and the GTA require an as-built survey at project completion to confirm the home was built exactly where it should be on the lot.

Commercial developments, condominium buildings, and multi-residential projects across the GTA require certified as-built surveys for project closeout, lender documentation, and municipality occupancy approvals.
Grading & Drainage Verification
GTA municipalities often require an as-built grading survey to confirm that final grades and drainage on a completed project match the approved grading plan — a common condition of occupancy permit approval.
Lender & Mortgage Requirements
Banks and lenders financing construction projects across Ontario often require a certified as-built survey at project completion before releasing final construction draws or approving permanent mortgage financing.
