You’ve been thinking about it for months- maybe years. A new kitchen. A bathroom that finally feels like yours. An addition that gives your family the space it needs. You’re ready to start.
But before you call a contractor or start pinning ideas on Pinterest, there are five mistakes I see homeowners make over and over again- mistakes that cost time, money, and a lot of unnecessary stress.
I’m Yifat, founder of Jifa Planning & Design, a residential planning and design studio based in Kirkland, WA. After 10+ years of helping homeowners across the Seattle area and Eastside transform their homes, these are the five things I wish every client knew before we started working together.
Mistake #1 — The Most Expensive Home Remodel
Mistake You Can Make
This is the most common- and most expensive mistake I see.
It goes like this: you have an idea, you call a contractor, they come to your home and give you a proposal. You say yes and work begins.
But here’s what most homeowners don’t realize: that proposal was based on assumptions. The contractor assumed a standard tile size. He didn’t know you wanted a bidet- so there’s no outlet for it. He priced for a basic layout because nobody told him otherwise.
None of this means your contractor was trying to trick you. He simply didn’t have enough information to give you an accurate quote. So as construction moves forward, the surprises start adding up- “that’s a change order,” “that’s an addition to the original quote,” “we didn’t plan for that.”
By the end, the project costs significantly more than you expected- not because anything went wrong, but because the decisions that should have been made before construction started were being made during it.
What to do instead: Before you talk to a contractor, invest in a design plan. When a contractor has complete, detailed drawings, they can give you an accurate price- and stick to it. No surprises, no change orders for things that should have been planned from the start.
Mistake #2 — Not Knowing What Permits You Need
A lot of homeowners assume that if a contractor is doing the work, permits are someone else’s problem. They’re not- at least not entirely.
Your contractor and their subs will typically handle the electrical and plumbing permits, which are often simple over-the-counter permits. But the building permit- the one that covers the actual structural and design work- that’s a separate process, and it needs to be pulled before construction begins.
In King County, Snohomish County, and most Eastside cities, a building permit is required for almost any structural work- moving walls, adding square footage, building an ADU, even some bathroom remodels.
Building without one isn’t just a technicality. If the city discovers unpermitted work, they can issue a Stop Work Order- shutting down your entire project immediately. And pulling permits after a violation is significantly harder, more expensive, and more time-consuming than doing it right from the start.
What to do instead: Before you budget for anything, find out what permits your project requires. I handle the building permit process for my clients- from preparing the drawings to submitting to the city and following up through approval.
Mistake #3 — Setting a Budget Without Understanding the Full Scope
“We want to keep it under $50,000” is something I hear often. And it’s a completely reasonable goal — until we discover that achieving the vision also requires moving a load-bearing wall, upgrading the electrical panel, and bringing the bathroom up to current code.
None of those things were in the original budget. But they’re not optional either.
What to do instead: Before you set a hard budget number, get a clear picture of the full scope of work. A design consultation — where we walk through your home and talk through your goals — will surface these hidden costs early, so your budget is based on reality, not assumptions.
Mistake #4 — Choosing Finishes Before the Layout is Finalized
I understand the excitement. You find the perfect tile, the dream vanity, the exact countertop you’ve always wanted — and you order it before the design is locked in.
Then the layout changes slightly. The vanity is 2 inches too wide. The tile you love doesn’t work with the new floor plan. Now you’re stuck with materials you can’t use, or you’re forcing design decisions around purchases you’ve already made.
What to do instead: Finalize your layout and design plan first. Once you know exactly what you’re building, material selection becomes much easier — and much more enjoyable. Everything gets chosen to work together, rather than piece by piece.
Mistake #5 — Underestimating the Timeline
Remodels almost always take longer than homeowners expect- not because contractors are slow, but because there are steps that simply can’t be rushed.
Permit approval in King County can take anywhere from a few weeks to several months depending on the project type and current city workload. Material lead times have stretched significantly in recent years. And once construction starts, unexpected discoveries inside walls or floors can add time to any project.
Here’s a tip most homeowners don’t know: even if you’re not ready to start construction yet, you can start the permit process now. Getting your permit approved in advance means that when you ARE ready to build, you can start immediately — rather than discovering that the permit is a months-long process standing between you and your contractor showing up.
The permit clock should start way before the remodel clock.
What to do instead: Build buffer time into your expectations from the start. If you’re remodeling before a family event, a move, or a lease end — work backwards from that date and start the planning AND permitting process earlier than you think you need to.
The Common Thread
Every one of these mistakes comes down to the same thing: starting too fast.
The homeowners who have the smoothest remodels — and end up happiest with the result — are the ones who slow down at the beginning. They invest time in planning, get clear on scope and budget, understand the permit process, and make design decisions in the right order.
That’s exactly what I help my clients do.
