Read Your Survey Before Building Your Dream Home

You’ve found the perfect lot in British Columbia—or think you have—but you’re not sure what you can actually build on it. Before you hire a designer or builder, you need to understand what your property survey is telling you. A survey is one of the most important documents you’ll ever hold, yet many homeowners barely glance at it. It’s the foundation for everything that comes next: your house plans, your permit application, and ultimately, whether your dream home fits on your land at all.

What a Property Survey Actually Shows You

A property survey is a legal document prepared by a licensed surveyor that maps the exact boundaries of your lot, the location of existing structures, easements, and other physical features. It answers the question: what land do you actually own, and what can you do with it?

The survey shows:

• The precise perimeter and area of your lot
• Where utilities run (water, sewer, gas, electrical lines)
• Existing buildings, driveways, and structures
• Easements (rights others have to use part of your land)
• Topographic contours if your lot is sloped
• Street frontage and access points

This information becomes critical when your designer or builder needs to understand where a new house can sit, how far it must be from property lines, and whether utilities can reach your proposed building location.

How to Read the Key Elements

A survey typically includes measurements from property lines to structures, marked in feet or metres. These distances matter because zoning bylaws in most BC municipalities require setbacks—minimum distances your house must maintain from the property line. A survey tells you exactly how much room you have to work with.

Elevation lines on the survey show slope and grade. If your lot drops away from the street or rises significantly, your designer needs that information to plan foundation work, drainage, and how the house will relate to the surrounding landscape. A flat survey drawing doesn’t capture this reality.

Easements are marked as shaded areas or notes. These are typically for utilities, storm drains, or pedestrian access. You cannot build over an easement. If an easement crosses your lot where you hoped to place the house, that eliminates part of your buildable area immediately.

Street lines and building restriction lines (marked as dashed lines on many surveys) show whether there are any covenants or restrictions on how close you can build to the street. These often exist on older subdivisions.

What You Should Do Before Meeting with a Designer

Before our team begins sketching house plans, review your survey carefully. Measure the lot dimensions yourself if you can, just to confirm the document matches reality. Walk the property and look for:

• Visible utility boxes, meters, or markers
• Slopes and drainage patterns
• Tree locations and size
• Neighbouring buildings and sight lines
• Street orientation and sun exposure
• Access points and where a driveway would logically sit

This physical walk-through combined with your survey reading will give you and your designer a complete picture before pencil touches paper.

When Your Survey is Out of Date

If your property survey is more than a few years old, ask yourself whether anything has changed. New utility lines installed, new fences built by neighbours, or encroaching structures can shift what’s actually possible on your lot. If you’re planning a major new build, a fresh survey is money well spent. It removes doubt and protects you during the permit process.

Why This Matters for Permit Drawings

When you eventually apply for a building permit, the municipality will ask exactly where your house sits relative to property lines, utilities, and existing easements. Your permit drawings must reference the survey. A designer or builder who hasn’t studied your survey carefully will likely draw something that doesn’t actually fit on your lot when the municipality reviews it. That means delays, redrawing, and costs.

By understanding your survey first, you avoid that trap. You and our team start with reality, not wishful thinking.

Common Survey Mistakes Homeowners Make

Many homeowners assume a survey is just a nice-to-have document. In fact, it’s essential. Others order a survey but don’t read it—they hand it to a builder and assume everything will work out. The builder may miss easements or setback requirements, leading to permit rejections later.

Another mistake: assuming a survey from five or ten years ago is still accurate. Municipal zoning can change, utilities can be relocated, and easements can be updated. If your survey predates recent zoning changes in your area, confirm current requirements with your local municipality.

Finally, some homeowners confuse a property survey with a site plan or floor plan. A survey is the lot only. A site plan (which our team creates during the design phase) shows how the house will sit on that surveyed lot in relation to setbacks, utilities, and other constraints.

What Happens at a Site Measure

Once you’ve chosen a designer, we typically conduct a site measure—a visit to photograph, measure, and document the lot firsthand. We bring the survey with us and verify it against what’s on the ground. We look at slopes, existing vegetation, access, and solar orientation. We check utility locations. This step bridges the gap between the paper survey and the real world.

The site measure, combined with your survey, gives our team everything needed to create house plans that will actually work with your lot, meet zoning requirements, and pass permit review.

Frequently Asked Questions

Do I need a new survey before designing my house?

If your current survey is recent (within a few years) and nothing major has changed on your lot or in zoning rules, you can usually proceed with design. However, if your survey is old or you’re unsure of its accuracy, a fresh survey is worthwhile insurance before committing to design fees.

What if my survey doesn’t show the sewer line or water connection?

Not all surveys include utility details. Contact your municipality’s public works department or your local water and sewer utility directly to confirm where the connection points are located. Our team can help you request this information or contact the utilities on your behalf.

Can I build right up to the property line?

No. Every BC municipality sets minimum setback distances from property lines. These vary by zone and by which property line (front, side, rear). Your survey shows the lines; your municipal zoning bylaw shows the setback requirements. Our team will confirm both before design begins.
