What Composes the Price Per Foot?

There are several different factors that influence the price per square foot when building a home in Ontario, including:

Building Permit Costs and Lay of Property

Based on the regulations in your area, you may be expected to pay anywhere from $10.000 to $30.000 for building and development costs. For instance, if your land in Ontario is in a low-grade area, expect construction to be somewhat more expensive because it requires more work in terms of boosting the grade and bringing in extra filling loads.

Size and Style of Your Home

The average size of a home in Canada comes in at 1.792 square feet. Of course, different families have different preferences and needs with regard to the scope of their homes, which may ultimately increase or decrease building costs. In any case, make sure you consider your sizing preferences when buying land in Ontario.

Construction Deadline

Time management can be tricky when it comes to construction, as there are plenty of external factors that might cause unexpected delays or interruptions. But if everything goes according to plan, it may take anywhere from 10 to 16 months to finalize construction.

Needless to say, complex shapes and designs might take a bit longer in terms of completion. Seeing as most people don’t think of a box-shaped house as their ideal home, this may be even more common than we realize.

Selecting a Contractor

If you’re keen on taking a DIY approach, you might save up some extra funds by acting as your own contractor. But if that’s not something that tickles your fancy, you should pay careful consideration to the type of contractor you select to manage the construction process. 

Make sure you do your research on the basics, including the type of work the builder specializes in, company licensing and insurance as well as a glimpse into some of their most recent projects for reference.

How to Get an Estimate for Building a House?

If you’re not one to rely on speculation but rather appreciate more specific data, then getting a ballpark estimate for your specific plan might help to ease your mind. In general terms, there are two ways you can go about this:

Construction Cost Calculators

Thanks to the many benefits of recent technological advances, you can get a reasonable estimate through online calculators. Though these readings may not always be accurate and should be taken with a grain of salt, they’re convenient and affordable ways to get some insight into what to expect.

Getting a Personalized Quote

In order to paint a more reliable picture of the costs of building a home in Ontario, your best bet would be to consult with a builder. These professionals take into account all the specifics of your particular project, including on-site requirements, size and layout.

Word of advice – talk to several different builders so that you get a better understanding of what the average cost to build a house in Ontario is. In this way, you’ll be able to make an informed decision that best serves you and your financial needs.

How to Finance Building a House?

Once you’ve received your estimate and you’re willing to move forward, you’ll have to allocate the necessary funds to go through with the plan. In that case, one of the easiest things to do is to apply for a mortgage, which can go in one of two ways:

Completion Mortgage

With this type of mortgage, the funds aren’t transferred until after the building process is complete. This allows you to make any changes you might deem necessary, including the overall amount you need. These changes can be made at least 30 days before your home is completed.

Progress-Draw Mortgage

This one is loaned out in increments, with each sequential set of funds corresponding with the relevant needs of the project. The lender will determine the exact amount you will receive, based on the particular stage in construction.

Managing Construction Costs

If you consider the initial expenses, it’s easy to see that building a house in Ontario is a bit cheaper – by around $7.000 – than buying a ready-made one. Naturally, you can cut down on these prices by paying close attention to the type of construction work you want. Here’s a quick look at some of the building blocks in the construction world:

Construction Type Average Cost
HVAC $13.000 – $17.000
Plumbing $8.000
Foundation $40.000 – $48.000
Electrical Wiring $13.000
Roof $4.750
Exterior Doors $700 a piece
Windows $1.000 a piece
Wall Sidings $8.000 – $20.000
Flooring $4 – $15 per square foot

Other ways that you can lower construction costs include:

Opt for a Smaller Home

The math here is simple – the larger the home, the greater the workload and resources required to finalize the project. If you want to save up on costs, design a smaller home that would result in minimal construction costs, all while giving you a warm and comfortable space to live in.

Save Up On Aesthetics

Believe it or not, interior finishes and decorations have a tremendous impact on the overall spending. Those of you that don’t have an eye for a particular interior decor style should go for minimal and simplistic designs that don’t come with a hefty price tag.

Reuse and Recycle

Throughout the years, there’s been a lot of talk about recycled items and their importance to the environment. But just as they’re favourable to the world around us, they can bring multiple benefits to our day-to-day lives as well. 

Using eco-friendly materials gives you the chance to save up money and add some personality to your home. That sounds like a win-win scenario, wouldn’t you agree?

Other Options for Custom-Built Homes

Despite the general benefits, house hunting comes with its own challenges. If you don’t exactly have the funds for building or buying a house in Ontario,  a home renovation can help you reduce the costs while helping you build home equity.

Truth be told, you don’t have to do a complete rebuild in order to refresh your home. Simply patch some things up here and there and you should notice an almost instant transformation of your personal space.
