Check local building codes, permit requirements, and ADA guidelines
Measure the rise from ground level to the entry threshold
Determine the required ramp length using the slope ratio
Choose the ramp location, direction, and landing areas
Select materials such as pressure-treated lumber, concrete, or aluminum
Gather tools, fasteners, anchors, post bases, and concrete if needed
Mark the ramp layout on the ground
Excavate and level the site
Install footings or concrete pads below frost depth if required
Set posts, supports, and framing members securely
Build the ramp frame with the correct slope and width
Install cross supports and bracing
Add landings at the top, bottom, and any required turns
Install the ramp surface boards or panels with proper spacing and traction
Add edge curbs or wheel guards
Install handrails on both sides at the correct height
Ensure rail extensions and graspable surfaces meet code
Check all connections, fasteners, and structural stability
Verify slope, width, landings, and clearances
Add non-slip treatment or surface finish
Inspect the completed ramp for safety and compliance
