What’s Actually in a Development Charge?
Development charges are not a single number — they’re usually stacked from multiple authorities, each billing separately:
| Layer | Who collects it | What it funds | When it applies |
|---|---|---|---|
| Municipal DC | Your local township or city | Roads, parks, fire, transit, community centres | Any new residential unit |
| County / Regional DC | Simcoe County, York Region, Halton, etc. | Regional roads, water/wastewater, transit | Municipalities within a county/region |
| Education Levy | School board (public + Catholic) | Land acquisition for new schools | All new builds in Ontario |
| Conservation Authority | NVCA, LSRCA, GRCA, etc. | Watershed planning & enforcement — see approval guide | Projects within regulated areas |
The Simcoe County “stack” — how it works in the Georgian Bay area
In most Simcoe County municipalities, you pay three separate DC bills: one to your township, one to Simcoe County, and one for education. The county levy alone is roughly $15,000–$17,000 for a single detached home (2026 rates). Tiny Township’s municipal DC is very low (~$4,800) but the county and education levies still apply — so your total is higher than the municipal fee alone suggests.

When Are Development Charges Paid?
In most Ontario municipalities, development charges are collected at the time the building permit is issued. This is a lump-sum payment — it is not spread over time like a mortgage. Make sure this amount is in your construction budget, not your contingency fund, because it is effectively non-negotiable. For a full walkthrough of the Ontario permit process, see our step-by-step building permit guide.
Standard new custom homes pay in full at permit. Use our Custom Home Building Calculator to make sure DCs are properly factored into your all-in budget.
Do Development Charges Differ for ICF vs. Wood Frame?
No. DCs are based on the type of dwelling unit and the municipality — not the construction method. An ICF home pays the same development charges as a stick-frame home of the same type. Read our honest ICF vs. wood frame cost comparison or use the ICF Cost Calculator. For a builder’s perspective see ICF vs. Conventional — is it worth it?

Frequently Asked Questions
Are development charges included in my builder’s quote?
Sometimes, but not always — and this is one of the most common “surprise” budget items. Always ask your builder explicitly: “Are development charges included in this price, and if so, which ones?” Some quotes include all DCs; others exclude them entirely, or include only the municipal portion. Get it in writing. Our guide to understanding builder allowances covers the other line items that quietly disappear from quotes. You can also learn how pricing works at ICFhome.ca for full transparency.
Can I negotiate development charges down?
Generally no, for a standard new home. DCs are set by bylaw and apply uniformly. You can appeal if you believe the charges were applied incorrectly or if your project qualifies for an exemption, but standard residential builds pay the posted rate.
Does renovating an existing home trigger development charges?
Usually not, unless you’re adding a new dwelling unit (like a secondary suite, garden suite, or ARU). Converting a basement to a legal apartment, for example, can trigger DCs in some municipalities. If you’re considering an addition or renovation, our additions and renovations page covers what to expect in Simcoe County.
What is the difference between a development charge and a building permit fee?
A building permit fee covers the cost of plan review and inspections — usually $1,000–$10,000 for a new home. Development charges are entirely separate and fund future infrastructure. Both are paid before a permit is issued. For a full breakdown see our Ontario building permit guide. If your permit package needs a heat loss calculation, OntarioHeatLoss.ca delivers BCIN-stamped CSA F280 reports in 48 hours.
Do development charges apply to rural lots with private well and septic?
Yes — DCs still apply to most rural properties even without municipal services. On a rural lot, the big hidden costs are more likely to be septic system design + installation and well drilling. Use our Ontario Septic System Calculator to estimate septic costs. For lot clearing, site prep, and septic installation in the Georgian Bay area, see Georgian Bay Siteworks.
How often do development charges change?
Municipalities can update DC bylaws at any time, and many do an annual or bi-annual inflationary increase. Rates are typically indexed to a construction cost index. If you’re planning a build 12–18 months out, check the current bylaw schedule — the numbers in this calculator reflect publicly available 2025–2026 rates but may not capture the most recent bylaw update in your municipality.

Builder’s reality note on development charges
The single most common DC mistake we see is homeowners budgeting for the municipal portion only — and then getting a surprise bill for the county and education levies at the permit counter. The total is typically 2–3× what people expect. For a build in Collingwood, for example, you might expect $15,000 in DCs and receive a bill for $48,000. Budget the full stack from day one.
