Build an Accessible Bathroom Compliance Checker for Remodelers

1. 1

   Encode both standards, side by side, for one room

   Start with restrooms and bathing rooms. Enter the dimensional requirements from the 2010 federal standards and from the accessibility standard edition your target jurisdictions adopt, and store them as separate rule sets so the tool can show where they diverge and which one governs the project at hand.

2. 2

   Design the input for a contractor standing in a room

   Room dimensions, wall positions, door width and swing, fixture locations, and mounting heights entered in under two minutes on a phone, with photo attachments. If the input feels like drafting software, contractors will not use it on site, which is the only place it matters.

3. 3

   Return decisions with citations, not opinions

   Every result should say pass or fail, the exact requirement text, the section number, and what would need to move by how much. Contractors use it to argue with an inspector or reassure a client, so the citation is as valuable as the verdict.

4. 4

   Handle the alteration questions people forget

   Work that alters an area can trigger an obligation to provide an accessible path of travel to it, including entrance, restrooms, and drinking fountains, with the added cost capped at a percentage of the alteration. Flagging that early is worth the subscription by itself, because discovering it at plan review reprices a job.

5. 5

   Say plainly that this is not legal advice or plan approval

   The tool checks dimensions against published standards; it does not replace a design professional, a plan reviewer, or an attorney, and local amendments vary. Put that in the product, in the export, and in the sales conversation. Being clear about the boundary is what makes professionals comfortable using it.

6. 6

   Sell through the trades that already care

   Aging-in-place and accessibility-focused remodelers, occupational therapists who specify home modifications, veterans housing programs, and commercial tenant improvement contractors. These buyers already have the problem and are already searching for the numbers.

7. 7

   Expand room by room and into documentation

   Kitchens, entries and thresholds, ramps and landings, and parking each have the same checkable structure. Then add a client-facing report showing what was verified and photographed, which contractors can hand to owners as proof of care and use to defend their work later.
