Rates went up sharply in 2022 and 2023. Ottawa buyers pulled back. Inventory rose. And yet, Ottawa home prices have continued to climb – up 8.3% in 2024 alone, according to the Ottawa Real Estate Board (OREB). People who expected a meaningful correction keep waiting for something that hasn't arrived.

The reason isn't complicated, but it's almost never covered in headlines. It comes down to what it actually costs to build a new home in Ottawa – and those costs have a floor that interest rates cannot move.

We explain the structural cost drivers below because understanding why new homes are priced the way they are is also the key to understanding why resale prices in Ottawa continue to hold. This is the version of the market story most Ottawa buyers never hear.

What Are Development Charges, and Why Do They Matter?

A development charge is a fee that the City of Ottawa collects from a builder every time a new home is created. The purpose is to fund the infrastructure required to service that new home: roads, water systems, sewer connections, transit, schools, parks, and recreation facilities.

Development charges in Ottawa are not small. As of 2024, a single new home in Ottawa carries approximately $60,000 to $65,000 in combined municipal development charges before construction even begins. That figure represents the combined City of Ottawa development charge, the education development charge, and area-specific charges depending on the location of the project.

These charges are non-negotiable and apply uniformly. They don't go away when lumber prices fall. They don't go away when interest rates rise. They don't go away when the market softens. They are a structural, legislated cost embedded in every new home built in Ottawa, and they flow directly into the price the buyer pays.

For perspective: $60,000-$65,000 in development charges represents approximately 8-9% of the average Ottawa freehold purchase price of $747,000 recorded in December 2024. Before a single nail is driven, before a concrete foundation is poured, the builder has written a cheque to the municipality for the equivalent of a substantial down payment.

The Other Structural Costs Builders Cannot Escape

Development charges are the most underreported cost driver, but they're not the only one. Three additional factors compound the pressure on new home pricing in Ottawa.

Construction labour shortages. Ontario needs approximately 154,000 more construction workers by 2034 to meet housing demand, according to BuildForce Canada. That shortage exists right now, and it pushes up wages across all trades. Framers, electricians, plumbers, HVAC technicians – the skilled labour required to build a home has become significantly more expensive, and the scarcity is structural, not cyclical.

Materials cost inflation. Lumber, steel, concrete, and insulation all saw significant price increases through the pandemic and have not fully retreated. Canada-U.S. tariffs have added further uncertainty to lumber pricing. Builders cannot lock in materials pricing years in advance the way they once could, and uncertainty gets priced into project costs as contingency.

Land and servicing costs. Shovel-ready residential land in Ottawa's growth communities – Barrhaven, Kanata, Stittsville, Riverside South – has become increasingly expensive. Servicing that land (running water, sewer, gas, and electrical to a raw subdivision) adds further cost before a single home is sold. The days of inexpensive raw land on Ottawa's periphery are over.

Why This Sets a Floor Under Resale Prices

Here is the link between new construction costs and the resale market that most buyers never think about.

If it costs a builder $700,000-$800,000 to produce a new freehold home in Barrhaven or Kanata – including land, development charges, labour, materials, financing costs, and builder margin – then no rational buyer will pay $650,000 for that same home on the resale market. New and resale compete directly in the same buyer pool, and new construction pricing sets a de facto price floor that resale properties trade around.

This is why Ottawa's resale prices have proven so resilient to rate pressure. It's not sentiment. It's math. The cost to replace a home sets a lower bound for what existing homes sell for, and that replacement cost has risen consistently and significantly for a decade.

We regularly see this dynamic play out with our buyers. When a buyer is weighing a resale home in Riverside South against a new build in a comparable community, the development charges embedded in the new home – invisible to most buyers – are exactly what explains the pricing gap between the two options.

How Permitting Delays Compound the Problem

Even when builders want to build, they often can't – at least not quickly. Development approvals in Ontario operate on timelines measured in years, not months. Site plan approvals, zoning amendments, committee of adjustment hearings, servicing agreements – a project that would take six months to approve in some jurisdictions can take two to four years in Ontario.

The result is that Ottawa's pipeline of new supply is far thinner than the political discussion about housing suggests. Ontario projected just 64,800 new housing starts in 2026, a number that has been revised downward three consecutive years. That gap between what Ottawa needs and what is getting built sustains demand pressure on the existing housing stock.

A one-time policy change like HST removal on new homes under $1 million – which Ontario announced for 2026 – can improve buyer affordability on qualifying units. But it cannot resolve the underlying supply constraint driven by labour shortages, development charges, and permitting timelines. Those are structural, and they take years to unwind.

What This Means for Ottawa Buyers

For buyers trying to understand Ottawa's pricing, the structural cost floor changes the frame. Ottawa home prices are not primarily a function of buyer sentiment or speculation – they reflect genuine replacement cost for new housing in a market with real labour, land, and regulatory constraints.

This has a practical implication: buyers waiting for a significant price decline in Ottawa are, in most cases, waiting for construction costs to fall. Specifically, they are waiting for development charges to be reduced (which requires political action), for skilled labour to become abundantly available (a decade-long problem), and for land servicing costs to decrease (which trends in the wrong direction). That is a long wait.

Buyers who understand this structural reality are better positioned to act decisively when the right property is available. Knowing that Ottawa's price floor is structural, not cyclical, removes the anxiety of trying to time the market.

What This Means for Ottawa Sellers

For sellers, the structural cost story is good news. A well-maintained, competitively priced resale home in an established Ottawa neighbourhood offers genuine value compared to new construction – and buyers who understand the cost math will recognize it.

Buyers considering new builds face development charges, HST (partially mitigated for qualifying homes), extended closing timelines of 12-24 months, and the uncertainty of construction delays. A resale home that needs minimal work, is priced accurately relative to comparable sales, and is ready for immediate occupancy competes very effectively against new construction in Ottawa's current environment.

The sellers who struggle are those who overprice against comparables, expecting the structural cost story to do their pricing work for them. The floor is real, but the ceiling is still set by comparable sales. Accurate pricing remains the most important factor in achieving a successful transaction.

Frequently Asked Questions About Ottawa Housing Costs

Q: Why haven't Ottawa home prices dropped significantly despite higher interest rates?

A: Ottawa home prices are supported by structural cost floors, not just demand sentiment. New homes in Ottawa carry approximately $60,000-$65,000 in development charges before construction begins, on top of rising labour and materials costs. These costs set a price floor that resale properties trade around. Since it costs $700,000-$800,000 or more to build a new freehold home in Ottawa's growth communities, resale homes priced below that level represent genuine value – limiting downward price pressure even when rates rise.

Q: What are development charges in Ottawa and who pays them?

A: Development charges are fees the City of Ottawa collects from builders when a new home is constructed, to fund roads, water, sewer, schools, and parks required to service the new unit. In Ottawa, combined development charges on a single new home reached approximately $60,000-$65,000 as of 2024. Builders pass these costs directly into the purchase price. Buyers pay them as part of the new home price without seeing them as a separate line item.

Q: Will Ottawa home prices ever become more affordable?

A: Meaningful affordability improvements in Ottawa require structural changes: reduced development charges through political action, increased skilled trade labour supply through training and immigration, faster permitting approvals, and higher volumes of shovel-ready land. These changes take years to materialize. In the near term, programs like Ontario's HST removal on new homes under $1 million can improve affordability on qualifying new builds, but they do not address the underlying supply constraints.

Q: Does resale housing compete with new construction in Ottawa?

A: Yes, directly and significantly. Buyers in Ottawa's suburban communities routinely compare resale homes against new builds in adjacent developments. New construction carries development charges, HST, extended closing timelines, and construction uncertainty. Resale homes that are well-maintained, move-in ready, and priced accurately compete very effectively. The development charge embedded in new construction is invisible to most buyers but is a major reason why Ottawa resale prices hold firm against new inventory.

Q: How do tariffs affect Ottawa home prices in 2026?

A: Canada-U.S. tariffs primarily affect Ottawa housing costs through construction materials – particularly softwood lumber, which is subject to ongoing trade disputes. Tariff uncertainty makes it harder for builders to lock in materials pricing, which increases project contingency and ultimately flows into purchase prices. Tariffs on Canadian goods sold to the U.S. also slow economic activity, which creates some demand-side pressure. The net effect in 2026 is likely modest upward price pressure from materials costs combined with some uncertainty around buyer confidence.

Q: Is there a difference in development charges across Ottawa communities?

A: Yes. Ottawa's development charges include a base city-wide charge plus area-specific charges that vary by location and the specific infrastructure required to service that area. Greenfield communities on Ottawa's periphery that require entirely new infrastructure typically carry higher total charges than infill developments in established areas that connect to existing systems. A local real estate agent familiar with specific communities can help you understand what development charges are embedded in a given new build's pricing.

Ottawa's price resilience isn't a mystery. It's a function of what it actually costs to build housing in this city, and those costs are not going down. Understanding that shifts your frame from waiting for a collapse that isn't coming to positioning yourself to make the best decision with today's market realities.
