Do You Need a Realtor for New Construction?
Buyers browsing model homes in Ottawa, Kanata, and Stittsville often ask the same question: Do you need a realtor for new construction, or can you deal directly with the builder’s sales representative? The short answer is that having your own realtor is almost always worth it, and in most cases, it costs you nothing extra. This page explains how buyer representation works with new builds, what a realtor actually does during the process, and where the exceptions to that advice tend to show up.
Builder sales offices are staffed by representatives who work for the builder, not for you. Understanding that distinction is the starting point for deciding whether independent representation makes sense for your purchase, especially in a region with as many active builders and communities as Ottawa’s west end.
Why Buyer Representation Matters With New Construction
The sales representative at a builder’s model home has one job: to sell that builder’s inventory on terms that favour the builder. They are not obligated to point out contract clauses that disadvantage you, compare the community to competing builders, or flag pricing that’s out of step with the market. A realtor working exclusively for the buyer has none of those conflicts.
This distinction matters most at two points: when negotiating the purchase agreement and when reviewing the fine print around closing adjustments, deposit structure, and occupancy dates. A written buyer representation agreement formalizes that a realtor is working in the buyer’s interest specifically, rather than splitting loyalty between both sides of the transaction, and it’s worth asking any realtor to explain these terms before registering at a builder’s sales centre.
Who Pays the Realtor on a New Build Purchase
One of the most persistent misconceptions is that bringing a realtor to a new construction deal adds to the buyer’s cost. In the large majority of cases, the builder pays the cooperating commission to the buyer’s realtor out of its own marketing budget, the same way it would pay if the buyer had come through its own sales office. This is standard practice across most builder-realtor arrangements in the Ottawa region, though buyers should confirm the specific commission terms with their realtor before registering at a sales centre, since first-visit registration is often what triggers commission eligibility.
| Who Pays | Typical Arrangement |
|---|---|
| Realtor commission | Paid by the builder, similar to a resale listing |
| Buyer’s out-of-pocket cost for representation | Usually none |
| Realtor’s obligation | Represents the buyer’s interests exclusively |
| When commission eligibility is set | Often at first registration or a visit to the sales centre |

Local Market Knowledge Across Ottawa, Kanata, and Stittsville
New construction activity is spread across several distinct submarkets, and each has its own pricing patterns, builder mix, and pace of development. A realtor who works these areas regularly can help a buyer compare a Kanata townhome against a similar product in Stittsville or Barrhaven, rather than evaluating a single builder’s offering in isolation.
This is particularly useful for buyers considering new construction homes in Ottawa or exploring new homes for sale in Kanata, where lot premiums, phase releases, and incentive structures can vary significantly between communities within the same few kilometres. A realtor can also point buyers toward builders with a track record in the specific area they’re targeting through resources like an Ottawa new home builders directory.
Stittsville and the surrounding parts of Kanata have seen steady new-build activity in recent years, alongside continued development in Barrhaven and Orléans. A realtor working across these areas day to day tends to know which phases within a community are releasing next, how lot premiums compare between builders, and which locations within a subdivision tend to hold value better over time. That kind of comparative view is difficult to get from a single builder’s sales centre, since its representatives typically don’t discuss competing communities.

What a Realtor Reviews in the Builder Contract
Builder purchase agreements differ from resale agreements of purchase and sale in ways that catch many buyers off guard. Standard builder contracts often include the right to substitute materials, adjust closing dates, and charge development-related adjustments at closing that are not always itemized upfront.
A realtor experienced with new construction knows which clauses are negotiable and which are standard across most builders in the region. Key areas typically reviewed include:
- Deposit structure and what happens to deposits if a closing is delayed
- Tarion’s new home warranty coverage and what it excludes are detailed further in this guide to the Tarion warranty in Ottawa
- Estimated closing adjustments for development charges and utility connections
- Upgrade pricing and whether it’s negotiable versus fixed
- Expected construction and occupancy timelines, covered in more detail in this timeline for building a new home in Ottawa
Because these contracts are drafted entirely by the builder’s legal team, having someone review them who isn’t paid by the builder is one of the clearest arguments for representation. Buyers are still free to have a real estate lawyer review the same agreement, but a realtor familiar with the specific builder can often flag concerns before the contract ever reaches that stage.
New Construction vs. Resale: Why the Advice Differs
Buyers sometimes assume that if they don’t need much help negotiating a resale purchase, they won’t need help with a new build either. The two processes are different enough that this assumption doesn’t always hold. Resale negotiations centre on an existing home’s condition and comparable sales; new construction negotiations centre on a contract, a floor plan, and a home that doesn’t exist yet.
The comparison in new build vs. resale breaks down these differences further, including how financing, inspections, and warranty coverage work differently between the two paths. Buyers weighing both options benefit from understanding these distinctions before they register with any specific builder.
Financing is one area where the two paths diverge in practice. A resale purchase typically closes within weeks of an accepted offer, while a new build purchase agreement may be signed a year or more before the home is ready, which means mortgage rates, personal finances, and even lender requirements can shift before closing actually happens. A realtor familiar with new construction timelines can help set expectations around this gap and flag when it’s worth revisiting financing arrangements as occupancy approaches.
When Buyers Might Consider Skipping Representation
There are a small number of situations where going directly to a builder without a realtor may make sense for a buyer. Someone with prior experience purchasing new construction, a strong understanding of construction contracts, and no interest in comparing multiple builders may prefer to handle the process independently.
Buyers on a very tight budget with little flexibility on price or upgrades may also find that the process is straightforward enough to manage directly, since builder pricing on standard units tends to be fixed regardless of representation. A buyer who is already committed to one specific community and one specific builder, with no interest in comparing alternatives, may also see less value in bringing in outside representation. Even in these cases, it’s worth asking whether a second, independent review of the contract terms is worth the time it takes, given that representation typically carries no direct cost to the buyer.
Hidden Costs Buyers Should Plan For
New construction purchases come with cost items that are separate from the purchase price and easy to underestimate. GST/HST applies to newly built homes, and buyers should confirm with their lender and lawyer how the GST/HST New Housing Rebate factors into their final numbers, since eligibility depends on the purchase price and whether the home will be the buyer’s primary residence. Ontario’s land transfer tax also applies to new builds, and the province’s land transfer tax rules outline how the tax is calculated and which rebates first-time buyers may qualify for.
Other common costs include utility connection fees, landscaping (often excluded from the base price), development charge adjustments, and moving expenses. A realtor who works regularly with new construction can flag which of these charges are typical for a given builder and which are worth questioning before signing. Buyers exploring financing should also look at the Home Buyers’ Plan and First Home Savings Account rules through the Canada Revenue Agency, and confirm mortgage pre-approval early using guidance from the Financial Consumer Agency of Canada. For buyers still deciding whether a new build fits their plans, buying a new build home in Ottawa walks through the process from deposit to closing in more detail.
Buyers should also confirm property tax estimates for a new build with the City of Ottawa, since taxes on new construction are often assessed differently in the first year of occupancy than they will be going forward. Checking active listings and recent new-build activity through REALTOR.ca can also help buyers benchmark pricing against what’s currently available across the region, particularly when comparing a specific community to others nearby.

Buyers considering a new construction purchase in Ottawa, Kanata, or Stittsville are welcome to reach out to Jason before registering at any sales centre, since that first visit is often what determines whether representation is available at no additional cost.
Do You Need a Realtor for New Construction (FAQs)
It’s not a legal requirement, but it’s strongly recommended. A realtor working exclusively for the buyer can review the builder’s contract, flag closing adjustments, and offer a comparison point that the builder’s own sales representative isn’t positioned to give.
In most cases, the builder pays the cooperating commission out of its own marketing budget, similar to how it would compensate its own sales staff. Buyers should still confirm the specific arrangement with their realtor before registering at a sales centre, since that first visit is often what establishes eligibility.
No. A realtor doesn’t replace any step in the builder’s sales process; they attend appointments, review paperwork, and negotiate alongside it. Buyers still choose from the same lots, floor plans, and upgrade packages available to anyone dealing with the builder directly.
Many builders require a realtor to accompany or register a buyer on their first visit for commission purposes. Registering solo first can sometimes limit whether representation is still available at no cost, so it’s worth asking a realtor about this before booking a model home appointment.
Base pricing on standard units is often fixed, but there is frequently more flexibility around upgrades, incentives, deposit structure, and closing cost credits than buyers expect. An experienced realtor knows which of these items builders in a specific community are typically willing to adjust.
Resale purchases centre on an existing home’s condition and comparable sales, while new construction purchases centre on a builder’s contract for a home that hasn’t been built yet. Financing timelines, inspection processes, and warranty coverage also work differently between the two, as outlined in this comparison of new build vs. resale.
Key items include the deposit structure and refund conditions, Tarion warranty coverage, estimated closing adjustments, upgrade pricing, and the expected construction timeline. A realtor familiar with new construction can walk through each of these before a buyer commits.
Yes. Buyers should budget for GST/HST considerations, utility connection fees, landscaping, development charge adjustments, and moving costs, none of which are always itemized clearly in the base price. A realtor or lawyer can help confirm which of these apply to a specific builder and community before closing.
