Planning a project in Scarborough.
Use official program information and a property-specific assessment before committing to the work.
Do Scarborough projects require a permit?
Permit and inspection requirements should be confirmed with the responsible municipality before work begins. Separate storm and sanitary connections may exist in some properties, so the protected line should be confirmed before installation.
Is a rebate guaranteed in Scarborough?
No. The municipality or region decides eligibility, approval and payment. The contractor can help organize documentation but cannot guarantee the result.
Can I choose interior or exterior only by preference?
Preference matters, but the sewer layout, depth, pipe condition, access, code requirements and program eligibility determine what is practical.
