Project planning

Whole-Home Accessibility Budget Calculator

Use broad project scope, home size, labor market, and contingency to set an independent planning range before requesting bids.

Project scope

Choose the closest group of planned changes.

Home area

sq ft

Conditioned area; used only as a complexity proxy.

Local labor market

A broad location adjustment, not a ZIP-code quote.

Contingency

Older homes and hidden conditions justify a larger reserve.

Estimated result

$36,816–$55,224

Midpoint target: $46,020 including 18% contingency.

How to interpret the result

Separate urgent safety work from convenience upgrades so the project can be phased.
Ask bidders to break out materials, labor, permits, design, and contingency.

The tool applies this planning structure:

scope allowance × home-size factor × labor-market factor + contingency

Structural, electrical, plumbing, asbestos, lead, or water damage can move a real quote outside the range.
This is a planning estimate, not an accessibility assessment or contractor quote.
