12 Money-Saving Tips from the Data
Actionable cost tips based on our own project pricing and published Ontario cost data.
Full lowering works out to roughly $80-$160 per square foot of basement area on a typical Toronto semi — beware quotes using a different scope, because per-square-foot numbers only compare if they cover the same work.
As a Quantity Surveyor, the first thing I check on a quote is the scope line. Published Toronto underpinning prices run anywhere from $50 to $450 per square foot because some figures are a dig-and-pour structural shell while others include a fully finished, rentable basement — the two are not comparable.
Fix grading and extend downspouts first — $1,000-$3,000 in drainage work solves 80% of moisture problems.
Bundle electrical with other renovation work — opening walls for framing saves re-work on wiring.
Upgrade to 200A panel during renovation — doing it later costs $2,000+ more.
Install a backwater valve — Toronto's Basement Flooding Protection Subsidy covers up to $1,600 per device (max two devices, within a $6,650 program maximum for work on or after November 12, 2025), and other GTA cities run similar programs.
Second-storey additions cost more per sq ft but don't require new foundation — compare total cost.
Design to municipal setback limits upfront — Committee of Adjustment variances cost $5,000-$15,000.
Stack incentives: the federal Multigenerational Home Renovation Tax Credit (up to $7,500) can combine with CMHC refinancing options — confirm current program rules with CMHC and the CRA before budgeting around them.
GC markup of 15-25% is standard — compare net cost, not just the management fee.
Fixed-price contracts protect you from overruns — cost-plus contracts give the GC less incentive to control costs.
PM saves 10-15% on construction costs through better coordination — the fee often pays for itself.
