This document protects both you and your builder, clearly outlines expectations, and sets the timeline for bringing your dream home to life.

Many buyers feel pressure to skim through and sign quickly, especially when they’re excited about moving forward. However, taking the time to thoroughly review and understand your contract can save you from potential headaches down the road. Think of this as the blueprint for your entire building experience.

Key Components of New Home Build Contracts

Every new home build contract should clearly outline several important elements. Let’s look at what you can expect to find in yours.

Purchase Price and Payment Structure

Your contract will specify both the base price of your home and how the final price is determined. These can be two very different numbers, especially if you’re adding custom features.

The payment structure typically includes:

An initial deposit when you sign the contract (often 5-10% of the purchase price in Alberta)
A construction draw schedule that outlines when additional payments are due as building progresses
Details about the final payment due at closing

Pay close attention to the conditions around your deposit. In most Alberta new builds, deposits are held in trust accounts, but it’s important to verify this protection exists.

Lot and Floor Plan Details

This section identifies your specific lot by its legal description and dimensions. It also references your chosen home model, elevation style, and square footage specifications.

Your contract should include or reference attached documentation such as site plans showing exactly where your home will sit on the lot, detailed floor plans with dimensions, and elevation drawings showing what your home will look like from the outside.

Lot characteristics can vary significantly. Some lots may offer walkout basement opportunities, while others might have different exposure directions affecting natural light. Make sure these details are accurately captured in your contract, as they significantly impact your daily living experience.

Construction Timeline and Schedule

While weather and current supply chain factors can affect exact dates, your contract should provide a reasonably detailed timeline. You should see an estimated construction start date, along with key milestone dates for major phases like foundation, framing, drywall, and finishing work.

The estimated completion date is perhaps the most anticipated piece of information, but it’s important to understand how delays will be communicated and handled. Most contracts include provisions for reasonable extensions due to weather, material shortages, or labour issues.

In Alberta’s climate, seasonal considerations often impact timelines. Winter builds typically include additional buffer time for weather-related delays that summer builds might not require. A good contract acknowledges these realities while still providing accountability for progress.

Warranties and Quality Assurance

One significant advantage of buying new is the warranty coverage. Your contract should detail the builder’s own warranty program and your coverage under the Alberta New Home Warranty Program. This typically includes:

one year on workmanship and materials
two years on delivery systems
five years on the building envelope
and ten years on major structural components.

The agreement should also outline what maintenance responsibilities fall to you after possession, such as caulking maintenance or furnace filter replacements. Understanding these requirements is essential for maintaining your warranty coverage.

You’ll also want to see details about how service requests are handled after you move in. Will there be a dedicated warranty representative? What’s the process for reporting issues? How quickly can you expect responses? A home builder with a strong warranty program will have clear answers to these questions in your contract.

Change Orders and Customizations

Many new home buyers end up wanting to make some changes after the initial contract is signed. Your agreement should outline the formal process for requesting these modifications.

The contract should explain how pricing for changes is determined and communicated to you. There will be deadlines for making customization decisions, as last-minute changes will disrupt the construction schedule. Each change should be documented through a formal change order that becomes part of your contract.

Changes almost always come with additional costs and potential timeline impacts, so understanding this process upfront helps set realistic expectations. Some builders in our communities offer more flexibility than others for mid-construction changes, but all should have a clear, documented process.

Common Clauses to Watch For

Beyond the basic components, several specific clauses deserve your careful attention.

Material Substitutions

Supply chain challenges have made substitution clauses increasingly common. These outline what happens if materials specified in your contract become unavailable. Look for language that:

requires substituted materials to be of “equal or better quality”.
defines how “equal or better” is determined.
specifies whether you’ll be notified before substitutions are made.
indicates whether you have any approval rights for changes.

A well-written substitution clause protects you and the builder from situations beyond anyone’s control while ensuring your home’s quality isn’t compromised.

Escalation Clauses

Given recent volatility in construction material costs, many contracts now include escalation clauses. These allow the builder to pass on certain cost increases to you. Pay attention to:

whether there’s a cap on potential increases.
the timeframe during which increases can be applied.
what specific materials or costs might trigger an escalation.
your options if costs increase beyond a certain threshold.

In Alberta’s building market, lumber prices have been particularly volatile. Some builders now include specific lumber escalation clauses that differ from other materials.

Cancellation and Refund Policies

Both you and your builder should have clearly defined rights to cancel under certain circumstances. Make sure your contract includes:

conditions under which the builder can cancel the contract.
conditions under which you can cancel.
whether and how much of your deposit is refundable.
how quickly refunds will be processed.

For example, financing contingencies might allow you to cancel and recover your deposit if you can’t secure mortgage approval, while the builder might have cancellation rights if permits can’t be obtained.

Deficiency and Inspection Clauses

Before you take possession, you will have opportunities for inspections. Your contract should have information about:

the pre-possession inspection process
how deficiencies will be documented
timeframes for addressing any issues
what happens if you and your builder disagree about a deficiency

Remember, seasonal considerations might affect exterior deficiencies—for instance, landscaping might need to wait until spring if you take possession in winter.

Costs and Fees to Anticipate

Your contract should clearly outline costs you could face beyond the home’s purchase price.

Tax Considerations

New construction homes in Canada are subject to GST, and depending on the province you live in, PST. Your contract should explain whether the quoted price includes these taxes.

Note: If your home will be your primary residence and is priced under $450,000, you may qualify for a GST rebate that reduces this amount.

Land transfer taxes will apply at closing, and you’ll also need to consider property tax adjustments between the builder and buyer. Since the builder has likely paid some property taxes in advance, you’ll reimburse them for the portion covering your ownership period.

Alberta has no provincial sales tax, which is an advantage compared to some other provinces, but municipal taxes vary by community. Talk to your builder for estimations of the property tax rates you can expect in your new neighbourhood.

Legal and Administrative Fees

Your new home purchase will involve various legal and administrative costs. You’ll need legal representation for contract review and closing, which usually ranges between $800 and $1,500 for a standard new home purchase in Alberta. Title insurance provides protection against property ownership issues and usually runs a few hundred dollars.

Some home builders also charge their own administrative fees for document processing and coordination. These fees can vary widely, so having them clearly itemized in your contract prevents surprises at closing

All told, you should budget between $1,500 and $3,000 for these combined expenses in a typical new home purchase.

Service Connections and Utilities

Getting your home connected to essential services involves various one-time fees. These include charges for connecting water, gas, and electricity to your property. You’ll also face setup costs for internet and communication services, plus any applicable municipal service charges.

In some cases, these connection fees are included in your purchase price, but often they’re additional expenses you’ll need to cover separately. In newer communities, some services might be bundled differently than in established areas. Your contract should clearly state which connection fees are included and which you’ll need to pay separately.

Landscaping and Final Touches

The extent of exterior finishing included in your home’s base price varies widely among builders. Your contract should specify exactly what’s included regarding your driveway, walkway, and deck. Will you get a concrete driveway or a gravel one? Is the deck included, or just the supporting structure?

Fencing responsibilities should be clearly assigned—will the builder construct fences, or is that left to you? The contract should also cover topsoil distribution and final grading to ensure proper drainage. Some builders include front yard landscaping while leaving backyards for the homeowner to complete, a common practice in many new communities.

You’ll also need to confirm what kind of landscaping requirements are needed for the neighbourhood. Your builder should provide you with these documents, although it might not be included in the official contract.

Understanding these exterior finishing details prevents disappointment when you move in and discover your outdoor spaces aren’t as you imagined.

Tips for Reviewing and Negotiating Your Contract

Now that you know what to look for, here are some strategies to help you review and negotiate effectively.

Read Every Section Carefully

It sounds obvious, but in the excitement of buying a new home, many people skim their contracts rather than reading them thoroughly. Take your time with the fine print and make notes on sections you don’t understand.

Compare the contract with any sales materials you received earlier. If a feature was prominently displayed in marketing materials but isn’t mentioned in your contract, don’t assume it’s included. Marketing brochures often show upgraded features that aren’t part of the base price.

Consider creating a checklist of everything you expect to be included in your home and verify each item appears in your contract. This methodical approach helps ensure nothing falls through the cracks.

Hire a Real Estate Lawyer

This isn’t the time to cut corners on professional advice. Choose a lawyer with specific experience in new construction contracts, not just general real estate transactions. The investment in proper legal review can save you thousands in avoided problems.

Provide your lawyer with all sales materials along with the contract so they can identify any discrepancies. Allow at least a week for this review process.

A good lawyer will identify potential issues you might miss and can suggest modifications to better protect your interests. They’ll also help you understand which contract elements are standard in the industry and which might be unusually restrictive or one-sided.

Ask Questions and Seek Clarification

Don’t hesitate to request more information about anything that seems unclear. If your sales representative made verbal promises about features or upgrades, get these in writing as part of your contract. Verbal promises are difficult to enforce later if they’re not documented.

Ask for examples or visuals if descriptions aren’t clear. For instance, if your contract mentions “builder-grade fixtures,” request photos or samples of what this actually means. Request plain-language explanations of technical terms, and follow up on vague language until you’re satisfied with the clarity.

Remember, your sales representative should be willing to explain anything you don’t understand. If they seem reluctant or dismissive of your questions, that’s a potential warning sign about how communication might proceed during construction.

Negotiate Thoughtfully

Not everything in a contract is set in stone. Prioritize what matters most to you rather than trying to negotiate every detail. In some cases, builders may be more willing to include upgrades rather than reduce the price, as upgrades often have better margins for them.

If the proposed timeline doesn’t work for your situation, discuss potential flexibility. Perhaps you need a later completion date to align with selling your current home, or maybe you need certain phases completed by specific dates for financing reasons.

Whatever you negotiate, ensure all changes are added to the contract in writing. Verbal agreements to modify contract terms have no legal standing—only written modifications signed by both parties are enforceable.

Most builders are willing to work with you on certain elements, especially if you’re clear about what’s most important to you and approach negotiations collaboratively rather than confrontationally.

How New Build Contracts Differ from Resale Contracts

If you’ve purchased a resale home before, you’ll notice several key differences in new build contracts. New builds include construction contingencies addressing what happens if building permits can’t be obtained or if construction faces major obstacles. Resale homes, by contrast, are generally purchased as-is with fewer contingencies.

Here’s a detailed comparison for you:

Category	New Home Build	Resale
Contract Type	Builder’s purchase agreement (customized to each builder)	Standard real estate contract (provincial forms used)
Negotiability	Limited; prices and terms are often set by the builder	More room for negotiation on price, conditions, and closing
Deposit Requirements	Higher deposits (often 5–20% paid in stages)	Typically 5% of purchase price, held in trust
Conditions (Financing, Inspection, etc.)	Rarely allowed—builder may require firm offer	Commonly included (financing, inspection, sale of current home)
Completion Timeline	8 – 12 months	30 – 90 days
Price Adjustments	Possible (due to material costs, tariffs, taxes)	Fixed price unless renegotiated
Warranty	Coverage for defects, major structural issues, workmanship	No builder warranty; home condition sold as-is
GST/PST/HST	May be included or added to the price; rebates may apply	Already included in resale home price
Land Transfer Tax	Applies on full purchase price	Applies on full purchase price
Property Taxes	May be estimated and subject to adjustment	Based on current municipal assessment
Customization	Buyers may select finishes and upgrades	No customization before purchase, only renovations after
Builder Incentives	May include upgrades, price reductions, or promotions	Seller incentives are very rare
Title & Legal Fees	May include builder-related clauses or extra legal costs	Standard legal fees apply
Home Inspection	Often limited to pre-delivery walkthrough (PDI)	Strongly recommended before purchase
Deficiency Resolution	Builder responsible for post-possession repairs	Buyer assumes responsibility for any issues after closing

Moving Forward with Confidence

Understanding new home build contracts empowers you to make informed decisions throughout your building journey. While the document may seem overwhelming at first, breaking it down into manageable sections makes it much more approachable.

Taking the time to review thoroughly now can prevent misunderstandings and disappointments later. Remember this contract establishes the foundation of your relationship with your home builder.

As you move forward into the exciting construction phase, keep your contract handy as a reference point for questions that arise.
