Stairlifts, ramps & safer entryways: what to know first
By Todd Whitehurst · Reviewed August 2026
Stairs and entryways are where a mobility limitation turns into an actual safety problem — and where the wrong quick fix can create a false sense of security. Here's what each option actually involves.
Stairlifts
A stairlift carries a seated person up and down a staircase on a motorized rail. A straight stairlift works for a staircase with no landings or turns and uses a standard rail, which keeps cost down. A curved stairlift is required for any staircase with a turn or landing, and needs a custom-measured, custom-fabricated rail — which is why it costs meaningfully more.
Stairlifts are a mechanical and electrical installation. This is not a DIY project — it involves securing a rail to the staircase structure itself and wiring a motorized unit that a person's safety depends on. Reputable installers also handle ongoing service and battery backup, which matters if the power goes out.
Ramps
A wheelchair ramp replaces or supplements a step at an entryway. Modular aluminum ramps are common because they can be installed without major construction and, in some cases, removed later. Wood-built ramps are more permanent and can be designed to match a home's exterior.
A commonly used general guideline for ramp slope is roughly 1 inch of rise for every 12 inches of ramp length (a 1:12 ratio) — meaning a modest step still requires a fairly long ramp to stay at a safe, manageable grade. This matters for planning: a ramp steep enough to fit a short space may not actually be safe to use.
Entryway safety, beyond the ramp
Handrails on both sides of any steps, not just one
Bright, motion-triggered lighting for evening arrivals
A level, non-slip landing at the door — even a small uneven threshold is a real trip hazard
A door that's easy to unlock and open without significant grip strength or balance
DIY-friendly vs. work that generally needs a licensed trade
Sometimes DIY-friendly: a short, simple modular ramp on level ground, added lighting fixtures, and a second stair handrail where mounting hardware has clear access to studs.
Generally needs a professional: any stairlift installation, any ramp requiring a permit or structural attachment, and any ramp long enough or steep enough that slope and stability calculations actually matter. See the Home Modification Cost Guide for typical cost ranges.
A note from experience: Ramps that look fine on paper sometimes turn out too steep once they're actually built and used by someone with limited strength or balance — this is one area where erring toward a longer, gentler ramp pays off. Stairlifts, similarly, are worth having installed and serviced by someone who does this regularly, given what's riding on the installation.
Signs it's time for a professional evaluation
Bring in a mobility specialist, occupational therapist, or licensed contractor if:
Your parent uses or will likely need a wheelchair, not just a walker or cane
The staircase has a landing or turn, ruling out a straight stairlift
There's more than one entrance your parent regularly uses that needs addressing
Local permitting or HOA rules might apply to a ramp or exterior modification
Frequently asked
Is a straight stairlift always cheaper than a curved one?
Generally yes. A straight stairlift uses a standard rail and is significantly less expensive than a curved stairlift, which requires a custom-fabricated rail to match the specific staircase. The Home Modification Cost Guide has the full range for both.
Can I install a wheelchair ramp myself?
A short, simple modular ramp is sometimes a realistic DIY project for someone comfortable with basic construction. A longer or steeper ramp, or one requiring a permit or structural attachment to the home, generally calls for a professional.
Does a stairlift work for someone using a wheelchair?
No — a stairlift carries a seated person up and down stairs, but a wheelchair user needs to transfer to the lift's seat and needs a separate wheelchair (or use one stored on each level) at the top and bottom. For a wheelchair user needing to move between floors, a home elevator or a ramp-and-single-level living arrangement is usually the more practical answer.
