You are not buying a ramp-shaped object. You are buying a usable route out of the house.
That route starts inside the door and ends where your parent actually needs to go: the car, sidewalk, driveway or pickup spot. If the installer measures only the steps, you can receive a technically finished ramp and still be left wrestling with a narrow doorway, a bad turn or a drop onto gravel.
Local option: New Plan Care gives families in the St. Louis area in-home help so a parent can stay home: companionship, help with bathing and dressing, meals, and overnight care. Call (314) 405-0887.
You are allowed to make the installer own the whole route before anyone starts digging holes.
Start with the trip your parent must make
Put the wheelchair, walker or other mobility device at the indoor starting point. Walk the route slowly. Measure the narrowest doorway and note every threshold, door swing, turn, rug, porch post, gate and uneven surface.
Then name the destination. “Outside” is not specific enough. Is the destination the passenger door of a sedan? A wheelchair van lift? A public sidewalk? The place where a paratransit driver takes over?
Tell the installer which device your parent uses, whether someone pushes from behind and whether your parent can operate the exterior door. Ask the installer to watch one real attempt if that can be done without forcing your parent through a route that does not work.
Make the site visit produce a drawing
Do not let the site visit end with “We can make it fit.” Ask for a drawing that shows the ramp runs, every landing, direction changes, handrails, edge protection, door swing and the surface at the bottom.
Ask the installer to write down:
• The vertical rise from the destination surface to the doorway.
• The proposed running slope and total ramp length.
• The clear width between handrails.
• The size of the top, bottom and turning landings.
• How the ramp meets the threshold.
• Where water will drain.
• Whether posts, anchors or footings will enter the ground.
• What must be moved, trimmed or repaired first.
The U.S. Access Board’s guide to ramp standards uses a maximum running slope of one unit up for every twelve units forward, requires level landings at the top and bottom and addresses clear width, handrails, edge protection and drainage. Those federal standards do not automatically govern every private-home project. Use them as questions for the installer, then ask the local permit office which rules govern this address.
Find the permit owner before work begins
Permit rules change across city, county and municipal lines. The City of St. Louis Building Division says new construction and structural changes generally require a building permit. St. Louis County describes limited situations in which certain on-grade or portable residential ramps may not require one. That is not permission to guess which rule applies to your house.
Ask the installer, in writing: “Which office has jurisdiction over this address, is a permit required, who will apply and who will schedule the final inspection?” If the answer is that no permit is required, ask for the name of the office consulted and the reason the project is exempt.
If the property is rented, belongs to someone else or sits under association rules, identify whose written approval must arrive before installation. Do not accept responsibility for collecting approvals unless you have actually agreed to do that work.
Turn the quote into an installation plan
The quote should name more than material and labor. Ask whether it includes site preparation, removal of railings or steps, threshold work, disposal, permit handling, inspection corrections and restoration of disturbed ground.
For a modular or portable ramp, ask who owns it, who may alter it and who removes it when it is no longer needed. For a permanent ramp, ask what maintenance the surface, fasteners, wood, concrete or drainage will require and who handles a problem found after installation.
Put the sequence in writing:
• Approval and permit responsibility.
• Final drawing approval.
• Material delivery and storage location.
• Site preparation.
• Installation window.
• Inspection, if required.
• Correction of unfinished items.
• First-use walkthrough.
• Receipt of warranty, maintenance and contact information.
Also ask whether the regular entrance will be blocked during the job and how your parent will enter or leave while work is underway. “It should only take a while” is not a care plan.
Protect the care day on installation day
Before the crew arrives, decide where your parent will be, which bathroom remains reachable and who answers questions. Move only the items the installer specifically asks you to move. Photograph the doorway, porch, siding, landscaping and proposed route before work starts.
At arrival, walk the drawing with the crew lead. Point to the exact bottom destination and confirm the door swing, landing locations and threshold transition. If the crew proposes a change, get the effect on slope, turns, drainage and destination explained before approving it.
You do not have to make a construction decision while helping your parent eat, toilet or transfer. Ask the crew to pause the affected work until you can compare the change with the written plan.
Test the installed route with the actual equipment
Do not make your parent the first test load. Start with an empty wheelchair, walker or scooter. Check that it clears the doorway, handrails, turns and bottom transition. Open the door through its full swing. Look for catches at the threshold and places where wheels approach an unprotected edge.
Then test the route the way it will really be used. If you push the wheelchair, can you control it while opening and closing the door? If your parent moves independently, can they reach the door hardware without rolling backward? Can the device turn on the landing without repeated repositioning? Does the route end on a firm surface that continues to the vehicle or pickup point?
Try the return trip too. A route that works downhill may expose a different problem uphill.
Do not sign off on a promise
Write every unfinished item on one list. Examples include a sharp edge, loose handrail, rocking section, threshold gap, blocked gutter, pooling water or a bottom transition that stops before the usable path.
For each item, record who owns it and when it will be checked. If an inspection is required, ask for the permit number, inspection result and documentation that corrections were accepted. Keep the final drawing, installer contact, maintenance instructions and warranty information with the rest of the house records.
Take photographs after completion from the doorway, each landing and the destination. Add one note explaining how the route is used and what must stay clear. That gives another caregiver something better than “The ramp is out back.”
If the ramp project is stuck
If you need help identifying a home-modification route or caregiver support in the St. Louis area, use Local Help for Caregivers in St. Louis. Ask each program what it covers, who selects the installer, whether approval must come before work begins and who owns follow-through when the installation needs correction.
You do not need to become a ramp designer. You do need one named person to carry the job from site measure through the first complete trip. If nobody owns that span, the unfinished pieces will land on you. Put the span on paper before the truck arrives.
