We've already established that uncapped development charges are the most dangerous trap in pre-construction. But knowing about the trap is different from knowing how to dismantle it. This guide outlines the exact mechanisms of the negotiation process between your lawyer and the builder.
The Standard Builder Clause
If you look at Schedule B or C of your newly signed pre-construction APS, you will find a paragraph that looks something like this:
"The Purchaser agrees to pay as an adjustment on closing the amount of any increase in development charges, education development charges, or parkland dedication levies enacted after the date of this Agreement."
This is a blank cheque. Builders write it this way because municipalities love increasing fees to fund infrastructure, and builders refuse to absorb that margin compression over a 4-year build cycle.
The Amendment Process
During your 10-day cooling-off period (for condos), your lawyer will draft an amendment to strike that open-ended language. The amendment will look like this:
"Notwithstanding anything to the contrary in this Agreement, the Purchaser's total liability for all adjustments relating to development charges, education levies, and parkland dedication shall not exceed $10,000.00."
The Builder's Response
Builders anticipate this. In a hot seller's market, the builder's lawyer will simply reply: "Rejected. The builder does not agree to caps." If this happens, you have a brutal decision to make: accept the unlimited risk, or cancel the deal and walk away.
However, in a balanced or buyer's market like 2026, the builder will likely respond with a counter-offer. They may reject $10,000 but offer a hard cap of $13,500. This is a massive victory for the buyer—you now have absolute certainty for your final closing cost calculations.
Other Crucial Caps
- Meter Installations: Cap utility meters at $1,500 to $2,000 total.
- Law Society Surcharge: The builder often tries to pass their own lawyer's admin fees ($200-$500) to you. Cap or strike this.
- Electronic Registration Fee: Cap at $250.
