A rail on the wall side
Rowhouse stairs usually have one rail on the open side. A second rail on the party wall side lets a person hold on with both hands, and for many people that is enough for now.

Second rails, lift preparation and a measured lift plan for narrow DC rowhouse stairs.
You reach us directly. Your number is never sold.
Most DC houses put the bedroom upstairs, so the stairs decide the day. In a rowhouse they run long and narrow against a party wall. In older detached houses they often turn at a landing.
A lift fits many of them. What changes is the kind of lift and the price, and only measurements tell you which. So we measure before anyone sells you anything.
A lift also has to fit the people around it. On a narrow rowhouse stair, even a folded seat takes up width, so the rest of the household needs room to pass. That gets measured too.

A straight stair with no turn is the simplest case for a lift. Straight stair lifts typically run $2,900 to $8,000 installed, per Lifeway Mobility's 2026 pricing guide.
Stairs that turn at a landing or wind at the top need a curved lift built to that stair, which costs more. The assessment tells you which kind you have.
Older DC houses may have no outlet near the stairs. We get power to the right spot and clear anything on the treads that would block the lift rail. A dedicated outlet at the top or bottom keeps the cord off the steps.
Typical installed ranges are on the stair lifts page and in the guide How much does a stair lift cost in Washington, DC?. Your own price comes in writing after the walk.
Many narrow stairs take a lift. The width, the landings and the headroom decide it, and the assessment measures each one.
A lift is quicker and cheaper to start. A main floor bedroom ends the climb but in a rowhouse often needs a new bath too. The report lays out both.
When a lift comes from a specialist installer, you hear that before you sign. Our crews handle the stair prep and the power, and we stay your single contact.
Yes. The rail of a stair lift mounts to the treads, so it can be taken out later and the screw holes filled.
A lift handles the stairs, yet the rest of a DC house can still need attention once it is in. Bathroom bars, brighter halls and a downstairs bedroom each get their own page.
