Coffee shop build-out cost is the first number every future café owner wants — and the one almost nobody will give straight. So here it is for Seattle & King County in 2026: realistic ranges, what's inside them, and what quietly pushes a café budget from reasonable to painful.
We say this as operators first. Before we were contractors, we opened our own coffee and food businesses — from a single cart to multiple locations. The numbers below are the ones we wish someone had shown us.
Coffee shop build-out cost per square foot
For planning purposes in the Seattle area, these ranges are realistic:
- Second-generation café space: roughly $100–$200 per sq ft. The previous tenant left plumbing, electrical, and maybe equipment you can reuse.
- Vanilla shell (new retail space): roughly $200–$350 per sq ft. You are building water, waste, power, and ventilation from scratch.
- Typical 1,000–1,500 sq ft café, all-in: most projects land between $150,000 and $450,000, including equipment.
- Espresso equipment package: $25,000–$60,000 for machine, grinders, refrigeration, and ice.
What's inside the number
A café looks simple from the dining side. However, most of the money is behind the bar and under the floor:
- Bar and millwork. The espresso bar is custom cabinetry with plumbing and power running through it — often $20,000–$60,000 on its own.
- Plumbing. Floor sinks, a mop sink, hand sinks, water filtration, and drainage for every drip tray. Health code decides the count, not you.
- Electrical. A commercial espresso machine wants its own high-amp circuit. Many older Seattle storefronts need a panel upgrade or a new service.
- HVAC and finishes. Heating, cooling, lighting, flooring, and the acoustic treatment that keeps a full room from sounding like a train station.
- Soft costs. Design, engineering, permit fees, and plan review — commonly 10–20% on top of construction.
The three things that move the price most
1. The shell you start with. This is the single biggest variable in any coffee shop build-out cost. A space that was a café last year is a discount; a space that was a phone store is a project.
2. Under-slab plumbing. Floor sinks need drains, and drains that don't exist mean saw-cutting concrete. Moving the bar 10 feet on the plan can add five figures under the floor. Therefore, we design the layout around existing plumbing whenever we can.
3. Power. Espresso machines, water heaters, and ovens add up fast. If the building's electrical service can't carry the load, the upgrade — not the equipment — becomes the budget story.
Menu creep belongs on this list too. For example, adding a small fryer turns a hoodless café into a Type I ventilation project. Our kitchen hood cost guide shows why that one decision can add $20,000–$60,000.
Permits and inspections in Seattle & King County
Even a small café goes through real review: building and trade permits from your city, plus health plan review from Public Health — Seattle & King County before you build, not after. In addition, your contractor must be registered and bonded with Washington L&I — verify anyone you hire.
Sequencing these reviews well is worth months. Our King County permit guide explains the order that keeps them running in parallel.
How to keep your coffee shop build-out cost down
- Lease the right space, not the cheap one. Low rent on a shell often costs more than higher rent on a second-generation café. Have a contractor walk the space before you sign.
- Keep water where it is. Design the bar around existing plumbing and the slab stays closed.
- Lock the menu early. Every cooking decision is a ventilation and plumbing decision wearing a disguise.
- Buy smart, not new. Refrigeration and back-bar equipment can be bought used; the espresso machine usually shouldn't be.
- Get real numbers before the lease. A build-out estimate on your actual space beats any per-square-foot average — including ours.
Because we've opened our own shops, we budget like owners: where the money protects revenue, spend; where it doesn't, don't.

How much does a coffee shop build-out cost in Seattle?
Most Seattle-area coffee shop build-outs land between $100 and $350 per square foot. For a typical 1,000–1,500 sq ft café, that usually means $150,000–$450,000 all-in, including equipment. A true second-generation space can come in lower.
Can I open a coffee shop for under $100,000?
Sometimes — but only in a second-generation café space where plumbing, electrical, and most equipment are already in place and code-compliant. Starting from a vanilla shell, under $100k is rarely realistic in King County.
How long does a coffee shop build-out take?
Plan on 6–12 weeks for permits and 2–4 months of construction after that, depending on scope. Second-generation spaces with light work move much faster than shell conversions.
Do I need a kitchen hood in a coffee shop?
Espresso machines and drip brewers don’t need one. Ovens for baking may need a Type II hood, and any fryer or griddle triggers a full Type I system — a $20,000+ decision. Lock the menu before you sign a lease.
