Best for: A builder with construction or code background who can turn dimensional standards into a tool a contractor uses on site
The ideaWhat this actually is
A field tool for remodelers and small design-build firms that checks a bathroom layout against the dimensional accessibility rules that trip people up: clear floor space, turning space, door clear width measured correctly, grab bar placement, fixture heights, and where the federal standard and the building code's referenced standard disagree. A contractor enters room dimensions on a phone and gets pass, fail, and the exact citation, on site, before the tile is set.
The opportunityWhy this idea works
Accessibility rules are dimensional, which makes them checkable, and they are split across documents, which makes them easy to get wrong. The 2010 federal standards and the accessibility standard most building codes reference do not agree on every number, and details like the 32 inch clear door opening measured from the face of the open door to the stop catch people out. Remodelers learn this the expensive way, at inspection, after tile is set. Existing software aims at architects, not at the contractor holding a tape measure, so a fast mobile checker that returns citations sells itself to the person who actually gets it wrong.
The openingWhy this idea is overlooked
Because the rules live in multiple standards that disagree, and because the existing tools serve designers rather than field crews, the contractor most exposed to a failed inspection has nothing built for them. The checkable, dimensional nature of the rules is exactly what makes a focused tool feasible, yet the category has been aimed up-market at architects. That leaves the highest-pain buyer, the remodeler standing in a half-finished bathroom, unserved and searching for the numbers.
The buildWhat you need to build this
| You need | Why it matters |
|---|---|
| Both standards encoded side by side | The 2010 federal standards and the code-referenced accessibility standard disagree on some numbers, so storing them as separate rule sets lets the tool show where they diverge and which governs. |
| A fast mobile input | Room dimensions, door width and swing, and fixture positions entered in under two minutes on a phone are what make it usable on site, which is the only place it matters. |
| Citations, not opinions | Every result must give pass or fail, the exact requirement text and section number, and how far something must move, because contractors use it to argue with an inspector or reassure a client. |
| Clear scope and disclaimer language | The tool checks dimensions against published standards; it does not replace a design professional, plan reviewer, or attorney, and local amendments vary, so that boundary must be stated everywhere. |
| Jurisdiction and code-edition handling | Different jurisdictions adopt different code editions and add local amendments, so the tool must let a user pick the governing edition for the project. |
| A client-facing report | A report showing what was verified and photographed lets contractors prove care to owners and defend their work later, which is a reason to keep subscribing. |

Questions
What people ask about this idea
Is this giving legal advice?
No. It checks dimensions against published accessibility standards and returns citations. It does not replace a design professional, a plan reviewer, or an attorney, and local amendments vary, which the product states plainly everywhere.
Why do two standards matter?
The 2010 federal standards and the accessibility standard most building codes reference disagree on some numbers, like clear floor space and turning requirements. The tool stores both and shows which governs a given project.
Who is the buyer?
Remodelers and small design-build firms, especially aging-in-place and accessibility-focused contractors, plus occupational therapists and veterans housing programs who specify home modifications.
What makes it usable on site?
A phone input that takes under two minutes and returns pass, fail, and the exact citation. If it feels like drafting software, contractors will not use it where it matters, which is standing in the room.
