Development charges, levies and the cap that saves you $30,000
What municipalities charge builders per new home, how the increase between signing and closing reaches your statement of adjustments, and what a cap does.

Every new home in Ontario carries municipal charges: development charges for roads, water and transit; education development charges; parkland levies; community benefits. They run from tens of thousands on a condo to well over $100,000 on a detached home in the most expensive regions, and they rise most years.
The builder pays them. Whether the increase between the day you sign and the day you close is passed to you depends entirely on your agreement.
Uncapped
The adjustments clause says the purchaser will pay any increase in development charges, levies and fees imposed after the date of the agreement. Sign in 2026, close in 2029, and three years of increases at 5–10% a year on a $120,000 base is $19,000 to $40,000 on your statement of adjustments. It is not in your mortgage. It is cash.
Capped
The clause says the purchaser's liability for such increases shall not exceed $X. Now the exposure is known and bounded, and you can budget it. Caps of $5,000 to $15,000 are common on detached homes when asked for.
How to get one
Ask during the lawyer-review period, in writing, through your agent. At launch, builders are competing for buyers and caps are granted often. After the release sells through, rarely. It is one of the few genuinely negotiable clauses in a builder agreement and it is worth more than most décor credits.
Estimating your exposure
The exposure tool uses regional order-of-magnitude figures by home type, projects them to your closing date at a growth rate you choose, and applies your cap if you have one. It is an estimate, not a quote — the actual by-law rates are public on every municipality's website — but it puts the uncapped number in front of you before you sign rather than after.
The other adjustments
Development charges are the largest, not the only. Tarion enrolment, utility meter installations, driveway paving, tree planting, grading deposits, and property tax instalments the builder prepaid all appear on the same statement. The closing-cost tool lists every one with a typical figure so nothing on closing day is a surprise.
Estimates only, for information. Not mortgage, tax or legal advice. Rates, rules and rebates change; confirm every figure with your lender, lawyer and the CRA before you rely on it.
