The house is the part buyers think about and the parcel is the part that decides the budget. Two identical designs on two parcels a short distance apart can differ by a very large sum, and almost all of that difference is knowable before the offer conditions expire.
What a builder finds that you will not
- Whether the lot supports the house you have in mind inside the setbacks, height and coverage rules that apply.
- Whether the grade supports a walkout, a side-drive garage, or the main-floor orientation you want — and what the site work costs if it does not.
- Where the water will go. Drainage and spring runoff paths are obvious to someone who has built nearby and invisible on a listing.
- Whether servicing is at the property line, and what it costs to bring it to the building site.
- Whether the soil will support a conventional foundation, or whether piling, over-excavation or engineered fill is likely.
- Access for equipment and deliveries, which on a constrained or steep site is a real cost line.
The conditional-period checklist
- Confirm the land use designation or zoning, and the setbacks, height, coverage and floor area rules that follow from it.
- Obtain a Real Property Report or survey where one exists, and identify easements and rights of way on title.
- Identify any registered restrictive covenant or architectural control, and read it in full.
- On an unserviced parcel: establish water supply, sewage feasibility and utility extension cost, in writing.
- On a serviced parcel: confirm service sizes are adequate for the home you intend, and what an upgrade costs.
- Check for environmental constraints — floodplain, riparian setback, wetland, slope, conservation authority jurisdiction, ALR status in BC.
- Check for subsurface interests — oil and gas leases, pipeline rights of way, mineral rights.
- Have a builder walk the parcel and give you a written site-work and servicing opinion.
- Have a designer produce a rough massing study confirming your programme fits the envelope.
A builder site visit and a rough massing study cost a small fraction of one percent of a custom home budget. Buyers routinely skip both, then spend twenty times that amount solving a problem the visit would have found.
When buying land first is the right call
None of this means never buy land first. Good parcels in desirable areas move quickly and waiting for a builder to be selected can cost you the site. The point is to make land purchase conditional on the due diligence above, and to bring a builder into the conditional period rather than after it.
