Contingency (percent)

Cost per unit is from your own quotes. The quantities and costs pre-filled for grab bars, ramp and doorways are examples only. Leave a line blank to skip it. A 10 percent contingency is a common rule of thumb, not a published standard.

Ramp helper: height to climb (inches)

Result

Fill the form and press Calculate.

Budget = sum of quantity x cost per unit for each change, plus contingency. A 1:12 ramp needs 12 inches of run for every 1 inch of rise, so a 24 inch climb needs a ramp 24 feet long.

Reference sizes from the ADA Standards

Ramp running slope: not steeper than 1:12 (section 405.2). That is 1 inch of rise for every 12 inches of run.
Ramp rise: 30 inches maximum for any ramp run (section 405.6), so a taller climb needs more than one run with a landing between.
Door opening: clear width of 32 inches minimum (section 404.2.3).
Grab bars: horizontal, 33 inches minimum and 36 inches maximum above the finish floor, measured to the top of the gripping surface (section 609.4).

Worked example

Four grab bars at $85 = $340, 24 feet of ramp at $150 = $3,600, and two doorways widened at $900 = $1,800. Subtotal $5,740.00, plus 10% contingency of $574.00 = $6,314.00. A 24 inch climb at 1:12 needs 24 feet of ramp, which is under the 30 inch maximum rise for one run. All prices here are examples, not market costs.

How it works

Each line = quantity x cost per unit; lines with both fields blank are skipped. Total = subtotal x (1 + contingency). Ramp run in inches = rise in inches x 12. Number of ramp runs = rise / 30 rounded up, with a landing at the top, the bottom and between runs.

FAQ

How steep can an accessible ramp be?

The 2010 ADA Standards give a running slope not steeper than 1:12, meaning 12 inches of run for each inch of rise, with a maximum rise of 30 inches for any one ramp run.

How wide should a doorway be?

The ADA Standards require a clear width of 32 inches minimum for door openings, measured between the face of the door and the stop with the door open 90 degrees.

How high do grab bars go?

The ADA Standards place horizontal grab bars 33 to 36 inches above the finish floor, measured to the top of the gripping surface. Position in a home should also suit the person using them.

Do the ADA Standards apply to my home?

Treat them as a design reference. Your local building code and a contractor or occupational therapist can say what applies to your home.
