Building a custom home is one of the most significant financial commitments most people will ever make. And yet, we’ve found that it's also one of the areas where people are most likely to enter the process with incomplete information, unrealistic expectations, or a budget that doesn't account for the full picture. That's not a criticism. Unfortunately, that’s just the reality of an industry that doesn't always lead with transparency.
We’d like to change that. We want to give you an honest picture upfront than have you discover the gaps halfway through a build. So here's what you actually need to know about budgeting for a custom home in 2026.
The Full Cost Picture
Construction costs are only one part of what a custom home actually costs. We wanted to give you a check list of items that need to be in your budget before you start.
Land. If you don't already own your lot, this is often the largest single cost. In the South Okanagan, lot prices vary enormously based on location, views, size, and whether the lot is serviced.
Site preparation. This is where surprises happen most often. Depending on your lot, site prep can include excavation, grading, rock removal or blasting, retaining walls, driveway construction, and utility connections. Get a realistic site assessment before finalising your budget.
Design and pre-construction costs. Architectural drawings, engineering, permits, and pre-construction design work all cost money.
Permits and development cost charges. Municipal permits and development cost charges (DCCs) vary by location and project. In some municipalities these are modest. In others they're substantial. Ask specifically about these costs for your lot and municipality.
Landscaping. This is consistently one of the most underbudgeted items in custom home builds. The construction budget gets your home built and it doesn’t typically include the lawn, planting, irrigation, fencing, or outdoor living spaces beyond basic grading.
Furniture and moving costs. Not construction costs, but real costs that come due around move-in and belong somewhere in your financial planning.
Contingency. Every custom home build should have a contingency budget- typically 10-15% of construction costs. This is set aside for the unexpected (because there will be something unexpected!). Unforeseen site conditions, material lead time changes, design decisions that evolve during the build.
How Cost-Plus Pricing Works (And Why We Use It)
There are different ways builders price custom homes. The most common are fixed price (you agree on a number upfront and the builder absorbs cost overruns or keeps savings) and cost-plus (you pay actual costs plus the builder's fee).
We use cost-plus pricing at Edgehill Homes because we believe it's the most transparent model for custom home building.
Here's how it works: you pay the actual cost of materials, labour, and trades (exactly what those things cost, with invoices to back it up) plus our fee for managing the project. There's no markup hidden inside a fixed price. There's no incentive for us to use cheaper materials and pocket the difference. You see exactly where your money goes.
The trade-off is that your final number isn't locked in from day one the way a fixed price contract appears to be.
What cost-plus does require is trust in your builder and a commitment to making decisions that stay within your budget. We provide regular budget updates throughout the process so you always know where you stand, and we flag budget implications before they become surprises.
Having an Honest Budget Conversation
The most important thing you can do before starting a custom home build is have a completely honest conversation about budget with yourself, your partner, and your builder.
Think about and really nail down what can you genuinely afford, accounting for the full picture of costs outlined above and a realistic contingency. That's your budget.
It also means being honest about priorities. What matters most: size, location, finish quality, outdoor space? Understanding your hierarchy of priorities means that when trade-offs are necessary (and they almost always are), you're making them intentionally rather than reactively.
And it means being honest with your builder. A builder who knows your real budget can design and advise accordingly. Honesty upfront saves everyone time and frustration.
Common Budget Mistakes to Avoid
Budgeting for construction only. As outlined above, construction is one component of total project cost. Budget for the full picture from day one.
Using per-square-foot numbers without context. These are starting points for conversation, not reliable budget numbers for your specific project.
Underestimating finish selections. Most people underestimate how significantly finish choices affect total cost. Get realistic allowances from your builder and understand what happens when you go over them.
No contingency. Every build needs one. Ten to fifteen percent of construction costs is not excessive- it's realistic.
Scope creep without budget adjustment. When the scope of your project grows during design (and it often does), the budget needs to grow with it or decisions need to be made about what comes out. Letting scope expand without adjusting budget creates problems later.
Choosing a builder based on the lowest bid. Low bids are low for a reason. Either the scope is incomplete, the allowances are unrealistic, or corners will be cut. Value in custom home building comes from transparency and quality, not from the lowest number on a page.
What We Can Tell You About 2026 Specifically
Construction costs have been volatile over the last several years. Material costs, labour availability, and supply chain factors have all contributed to significant price movement that made budgeting challenging.
We wish we could tell you it’s going to stabilize, but the recent ongoing trade tensions between Canada and the United States have created real questions around material costs.
For now material costs remain elevated in many categories and skilled labour continues to be in demand in the South Okanagan. We suggest you build your budget based on current realistic costs, not costs from a few years ago or costs you've seen quoted in other markets.
The Bottom Line
Custom home budgeting requires honesty, thoroughness, and realistic expectations. And it requires a builder who will be straight with you about costs rather than telling you what you want to hear to win your business.
