It’s easy to fall in love with what a home could become.

Maybe the location is exactly right, the property has the land you’ve been looking for, or the existing architecture has the kind of character you’d never be able to recreate from scratch. You can already see the changes: opening up the main living spaces, reworking the kitchen, adding the primary suite, extending the house into the garden, or completely rethinking how the home works for your family.

And sometimes, that vision is exactly what makes an existing home worth buying.

But before you fall too far in love with the possibilities, you need to understand what you’re actually buying and what it will take to get from the house that exists today to the one you’re imagining. The most beautiful renovation opportunities can come with structural limitations, zoning restrictions, site challenges, outdated systems, or a scope of work that is far greater than it first appears.

A home can have great bones and still be the wrong project. Here’s what I want you to know before you sign that dotted line.

Look Beyond the Walls

Yes, get a home inspection, but if you’re planning to change anything about the structure, layout, or footprint of the home, that’s not enough.

Ask for:

  • Any existing plans (from the city or previous owner)

  • A property survey or site plan

  • Geotechnical or environmental reports, if applicable. You may have other restrictions that you may be unaware of.

These documents provide quick answers and tell you way more about what’s actually possible than a walk-through ever could. But not all homes come with this information. It's not a dealbreaker but something to factor into your timeline and budget. Requesting a survey or report(s) prior to closing.

Check With Your City

This is the step most people skip… and end up regretting. If you have any intention of building an addition, changing the layout, or even adding a suite, you need to check:

  • What’s allowed under the zoning

  • Setback & Site Coverage and how they affect the usable building area

  • Whether you’d need a variance, rezoning, or other permits

  • What your floor area ratio (FAR) is and how much of it is already used

This might sound overwhelming, but it’s as simple as calling your city or checking their online planning portal. Some municipalities have interactive maps (GIS) that let you input the address for the zoning of your property.

Have a Pro Walk It With You

That brings me to this very important step. Before you put in an offer (or during conditions), pay a general contractor, carpenter and/or architectural designer to walkthrough the house or review the existing plans with you (or schedule a consulting call with us). Someone who you can share the big picture with and tell you where the holes could be.

They’ll help you understand:

  • What changes are realistic

  • Where structural issues may come up

  • If your timeline and budget are even close

And if you’re considering something more complex, you might need to bring in a structural engineer. They don’t need to provide a report, just a quick consult can flag major issues or give you peace of mind.

This is especially important if you're planning to:

  • Remove or move walls

  • Raise or dig out a basement

  • Add a second storey

  • Expand the footprint

Dream Freely, Plan Wisely

You’re allowed to want what you want: The dream ensuite, the open kitchen, the addition that turns this into your forever home. Just give that dream some structure. Do the boring part first (I promise, it pays off later) and surround yourself with people who will tell you the truth about what’s possible, not just what you want to hear.
