Use this wheelchair ramp checklist to prepare rise measurements, slope questions, landings, handrails, materials, drainage, and permit review.

One number controls every ramp decision: the total rise from the ground to the door threshold. The common accessibility standard is a 1:12 slope, one foot of ramp for every inch of rise, so a 24 inch rise implies roughly 24 feet of ramp plus level landings. Measuring rise first tells you instantly whether a straight run fits or the design needs turns.
The rest of the checklist covers what quotes silently differ on: landing sizes at the door and turns, handrails once rise exceeds a few inches, edge protection so wheels cannot slip off, surface traction in rain, and drainage so the ramp does not become an ice sheet in winter.

Ranges and rules on this page draw on the official sources below. Program amounts and standards change, so confirm current details on the source itself before acting.
Using the standard 1:12 slope, the ramp needs one foot of length for every inch of rise, so a typical 20 to 30 inch porch rise needs 20 to 30 feet of ramp plus level landings at the top, bottom, and any turn.
Accessibility standards call for handrails on both sides once a ramp rises more than 6 inches. Even where residential code is looser, rails and edge protection are cheap compared with a wheel slipping off the side.
Often yes for permanent ramps, since they are structures with footings and rails, while portable and some modular ramps usually do not require one. Rules vary by city and HOA, so confirm before ordering materials.
