How much will my home renovation cost?
That's the number one question I get from homeowners starting a renovation. And my honest answer — every single time — is the same: more than you think.
Construction costs have climbed significantly since the pandemic, and they haven't come back down. Renovations are especially hard to price without a detailed project scope, because costs vary dramatically depending on what kind of work you're doing and what the existing conditions are.
Are you moving plumbing fixtures? Opening a load-bearing wall? Does your house need to be rewired before you add the kitchen of your dreams? The answers to questions like these can swing your budget significantly — and the tricky part is, you may not know the answers until you're further into the design process. That's not a reason to panic. It's a reason to plan carefully from the start.
Not all square footage costs the same.
This is one of the most important things to understand before you set a renovation budget. A kitchen or bathroom renovation costs far more per square foot than a bedroom, office, or dining room — because kitchens and bathrooms involve plumbing, cabinetry, appliances, and tile work that add up fast. Structural changes — opening walls, adding square footage, modifying the roofline — carry their own significant costs. So does updating whole-house systems like electrical panels, HVAC, or plumbing that hasn't been touched in decades.
Before you build a budget, identify what kind of work your renovation actually involves. The answer shapes everything.
Know where you want to spend and where you'll save.
This is worth a real conversation between you and your partner before design begins. Do you have expensive tastes in finishes? Are appliances where you want to invest, or are you a simpler soul who cares more about function than flair? Disagreements discovered mid-project are costly — in money and in stress. As you start planning, try labeling the different zones and features of your renovation with a simple scale: $, $$, $$$. It brings clarity fast and helps your architect or contractor design toward your actual priorities.
Build in a contingency — a generous one.
For a renovation, I recommend budgeting a contingency of 25% or more when you are early in the design process. That feels high, but renovations have a way of revealing surprises — old wiring behind a wall, a subfloor that needs replacing, a plumbing configuration that complicates everything you thought was simple. The older your home, the more likely you are to encounter conditions that weren't visible until demo day. Budget for the unexpected, because in a renovation, the unexpected is almost guaranteed.
That contingency percentage will come down as your scope gets finalized — but it will stay higher than it would for a new build. That's just the nature of working with existing conditions.
Get a realistic sense of costs early.
One tool worth knowing about is Scopify — a free online resource that gives you a general renovation budget estimate based on your zip code. You can plug in different scope scenarios and see how the price shifts depending on what you include or cut. It won't replace a detailed contractor estimate, but it's a useful starting point for understanding what your project might actually cost before you fall in love with a plan you can't afford. You can find it at scopifyapp.com.
Think about where you'll live during construction.
This one catches people off guard. If your renovation involves the kitchen, primary bathroom, or major systems like HVAC or electrical, you may not be able to stay in your home — or you may be living in significant disruption for weeks or months. The cost of temporary housing, eating out, or renting storage for your belongings is real, and it needs to be part of your budget from the beginning. Even if you plan to stay in the house, think through which spaces will be offline and when, and plan your phasing accordingly. A renovation that feels manageable on paper can feel very different when your kitchen is a construction zone and you're washing dishes in the bathroom.
Phase your project if you need to.
Not every renovation has to happen at once. A master plan — a document that maps out your full renovation vision in a logical, prioritized sequence — lets you tackle work in stages without making decisions today that close off options tomorrow. Moving a wall in phase one affects where plumbing can go in phase two. Choosing flooring now means committing to a finish that will need to carry through future rooms. A phased approach protects your budget and keeps the project manageable — but only if the phases are planned together from the beginning, not invented one at a time as money becomes available.
You might not need to add on — you might just need a better plan.
Before you budget for an addition, it's worth asking whether your existing space is actually working as well as it could. Awkward floor plans, poor circulation, and wasted square footage are more common than you'd think — and reworking what you already have is almost always less expensive than adding on. An architect can help you see your home differently. Sometimes a wall removed here, a doorway relocated there, or a room repurposed entirely can solve the functional problems you've been living with for years. The square footage was always there. It just needed a better story.
Understand what your contractor can — and can't — tell you early in the design process.
If you meet with a builder before you have a renovation plan, the quotes they provide can be wildly different — if they provide one at all. It's impossible for a contractor to give you a detailed estimate without a complete set of drawings that clearly defines the scope of the work. There are too many unknown variables that can't be answered by standing in your kitchen and waving your arms around to indicate your changes.
That's another place where working with an architect early pays off: a well-defined scope produces more reliable bids and reduces the gap between what you expect to spend and what you actually spend.
About halfway through the design process, it's a great idea to bring your contractor and designer together to review the plans. Contractors often have excellent input on phasing, sequencing the work, and the practical realities of construction that can save you real time and money in the long run. The earlier that conversation happens, the better.
Your architect is part of your budget strategy.
A licensed architect doesn't just produce drawings — they help you understand what your renovation will actually involve before a contractor sets foot on site. They identify the structural, mechanical, and sequencing issues that affect cost. They help you figure out whether you need an addition or just a smarter floor plan. They coordinate the decisions that, left unmanaged, become expensive change orders. And they help you clarify where to spend and where to save — so the money you invest goes toward the things that matter most to your family.
