Building permit line as quoted by contractorsWhat a contractor bills for the permit, not what the City charges. Nusite lists it inside a $2,000 to $5,000 permits-and-engineering line, alongside $1,000 to $3,500 for the engineer's assessment and drawings; the direct City of Toronto minimum fee is $214.79.
Exterior waterproofing, as part of a basement-lowering projectNusite prices this only where exterior work is needed; an interior waterproofing system on the same job is $5,000 to $8,000, and the waterproofing line as a whole is $5,000 to $15,000.
Structural engineer site inspection / assessmentOpen-ended at the top: SEPCO writes $600 to $1,200+. Covers a site visit, assessment and an optional letter or report.
Structural engineering drawings for underpinning permitStrong Basements' Toronto figure for the engineer to design the underpinning around the home's structure and soil and produce a drawing set for the permit application and construction. Some design-build firms fold it into a project package instead of billing it separately. Neither the $1,500 floor nor the $6,000 ceiling this guide used to show is on their page.
Structural engineer hourly rate (Toronto/GTA)An hourly consultation rate for advice only. SEPCO puts Toronto and the GTA at the top of the provincial band, $150 to $300 per hour, for highest demand and fastest turnaround.
Foundation crack repair - polyurethane injection (leaking crack)DryShield's polyurethane tier, for stopping active leaks with a flexible seal that tolerates seasonal movement. HST and finishing work are not included unless quoted. The $500 floor this guide used to show is not on their page.
