If someone in your household uses a wheelchair, a stairlift is off the table — the rider has to be able to stand and transfer. That leaves two options, and they get confused with each other constantly.
The short version: a platform lift solves one short rise, usually at an entrance, for roughly half the cost of an elevator. A home elevator solves every level in the house. The dividing line is how far you need to travel, not how much you want to spend.
What Each One Is
A vertical platform lift — also called a wheelchair lift or porch lift — is an open platform that rises straight up a short distance. You roll on, ride up, roll off. It’s most often used outdoors at a raised entry, or indoors at a split-level landing. We’ve put up a dedicated platform lift service page covering the models and installation.
A residential elevator is an enclosed car travelling in a shaft between full floors. It carries people and everything else — laundry, groceries, luggage — and it serves every level it stops at.
The Four Questions That Decide It
1. How far does it actually need to go?
This is the main one. Platform lifts are designed for short rises — commonly up to about a storey. If the level change is a porch, a deck, or a split-level half-flight, that’s platform lift territory. If you need to get from a basement to a second floor, it isn’t.
2. Is the problem getting into the house or moving around it?
A surprising number of Seattle and Eastside accessibility problems are entrance problems. Someone navigates their single-level home perfectly well, but the five steps from the driveway to the porch have made the house a trap. A platform lift fixes exactly that, and an elevator would be an expensive way to solve a problem that isn’t inside.
3. Is there room for a ramp?
Worth asking honestly, because a ramp is cheaper than either. The catch is slope: a safe ramp needs a long, gentle run, and a rise of more than two or three steps quickly demands more length than most Seattle lots have. Where a ramp fits, build the ramp. Where it would need switchbacks across the whole front yard, a platform lift takes a fraction of the footprint.
4. What’s the budget, and what does it have to last for?
Platform lifts run roughly $18,000–$32,000 installed. A standard two-stop home elevator runs $35,000–$55,000, and three or more stops push into $55,000–$85,000. The gap is real, but so is the difference in what you get.
Side by Side

|---|---|---|
| Typical installed cost | $18,000 – $32,000 | $35,000 – $85,000+ |
| Travel distance | Short rise, about a storey | Full multi-storey |
| Wheelchair accessible | Yes, no transfer | Yes, no transfer |

| Outdoor capable | Yes, weather-rated models | No |
| Building work required | Modest — pad and power | Substantial — shaft, structure, electrical |
| Carries goods as well as people | Limited | Yes |
| Permit authority | SDCI inside Seattle; WA L&I everywhere else | |
Where Each One Clearly Wins
Choose a platform lift when the barrier is a front porch, a deck, a garage step, or a sunken living room; when a wheelchair is in daily use; when a ramp won’t fit; or when the house otherwise works fine on one level.
Choose an elevator when the household lives across two or more full floors; when bedrooms are up and living space is down; when you’re carrying things between levels constantly; or when you’re planning for the next twenty years in this house rather than the next three.
The Combination Nobody Mentions
On split-entry and daylight-basement homes — of which Seattle and the Eastside have thousands — the answer is sometimes both, and that’s not as extravagant as it sounds. A platform lift at the entry gets someone into the house; an elevator or a stairlift handles the interior flight. Solving the entrance first is often the cheaper, faster half of the problem, and it’s the half that determines whether someone can leave the house at all.
What We’d Ask You
When people call about this, three questions usually settle it before we’ve even scheduled a visit: how many inches of rise, is a wheelchair involved, and is the barrier inside or outside. If you can answer those, we can usually tell you which direction you’re headed on the phone.

Request a Free EstimateFrequently Asked Questions
Is a vertical platform lift the same as a wheelchair lift?
Yes — vertical platform lift, wheelchair lift and porch lift all describe the same equipment: an open platform that travels straight up and down a short rise, carrying a user who stays in their wheelchair or scooter.
How much does a platform lift cost in Seattle?
Generally $18,000–$32,000 installed for a residential unit, depending on rise, indoor or outdoor model, and how much site work the location needs. That compares with $35,000–$55,000 for a standard two-stop home elevator.
Can a platform lift be installed outside in Seattle?
Yes. Outdoor models use sealed components and weather-rated controls and are common on exposed front porches and decks here. Drainage at the base is planned at survey so water doesn’t collect around the mechanism.
Can a platform lift reach a second floor?
Generally not. These are short-rise machines, and travel beyond about a storey is where a residential elevator becomes the appropriate solution — both for comfort and because an open platform isn’t well suited to longer travel.
Is a ramp a better option than a platform lift?
For a very short rise, often yes. Ramps must be built at a gentle enough slope to be safe, so every inch of rise needs substantial length — and on most Seattle lots that becomes impractical beyond two or three steps.
Do platform lifts need a permit in Seattle?
Yes. SDCI is the permitting authority inside Seattle city limits. On the Eastside the elevator permit comes from Washington State L&I with the city issuing the building permit. We handle the permitting either way.
