The compliance platform
that cites its source.

Stop guessing what the ordinance says. Codecheck checks your project against the actual text of U.S. municipal codes and shows you the exact section behind every result — not a paraphrase, not a summary.

The problem

Compliance research burns hours your team doesn't have

The U.S. has thousands of municipalities, each with its own zoning code, building amendments, and local interpretations. The current process is manual, fragmented, and expensive.

Construction site compliance review

Hours lost to PDF research before every project

VDC coordinators and estimators spend hours digging through hundred-page zoning PDFs to answer basic questions before a project can start — questions that should take seconds.

⚠️

Missed requirements become expensive change orders

A single missed setback or parking ratio discovered during plan review means redesign, resubmittal, and schedule delays. Avoidable compliance errors cost the U.S. construction industry billions annually.

📋

Summaries go stale — and nobody has the source

Third-party summaries and internal cheat sheets go out of date silently. When an inspector quotes the ordinance, nobody has it. Codecheck always shows the source section so your team can stand behind every answer.

The solution

Compliance answers that cite every source — instantly

Codecheck checks your project parameters against the actual text of municipal codes and returns pass, fail, or needs-review for every applicable rule — with the exact article and section cited.

🏛

Actual ordinance text, not summaries

Every rule is sourced directly from the official municipal code. Citations include the exact article, section, and table number — the same citation a plan reviewer would use.

Results in seconds, not hours

Enter your project parameters and get a complete pass/fail breakdown across dimensional, MEP, building code, use, and site rules — no PDF-digging required.

Industry impact

Why this changes the way construction teams work

The construction industry loses hundreds of billions annually to avoidable rework, plan review failures, and compliance delays. Codecheck is designed to eliminate the most preventable category of that loss.

$273B
Annual rework cost in U.S. construction
Industry research estimates that 30% of construction costs are tied to rework — a significant portion of which stems from avoidable compliance errors caught too late.
14–21
Days lost per compliance-related resubmittal
A single missed zoning requirement found at plan review can delay project start by 2–3 weeks while redesign and resubmittal happens, cascading across the entire schedule.
6,495+
Zoning districts checked in under 30 seconds
What used to take a VDC coordinator 45+ minutes of PDF research now takes under 30 seconds — with a complete, source-cited audit trail that can be shared instantly.

Who we serve

Built for every professional who touches compliance

Whether you're coordinating BIM models, estimating a bid, designing a site plan, or reviewing drawings — Codecheck gives you the ordinance knowledge you need without the research hours.

🏗

MEP Contractors

Verify equipment placement, mechanical setbacks, rooftop screening requirements, and building code amendments before detailing begins — across any jurisdiction in our 9-state coverage area.

📐

Architects & Designers

Check setbacks, heights, lot coverage, parking ratios, and sign ordinances for any covered municipality before schematic design is complete — with source citations ready for submittals.

💼

Developers & Owners

Validate site feasibility, understand what's permitted by right versus special use, and surface compliance issues before due diligence closes — at a fraction of the cost of a code consultant.

💻

VDC & BIM Professionals

Integrate compliance checks into Revit workflows and coordination pipelines via the native plugin or REST API. Import drawing data and run checks without leaving your BIM environment.

Our purpose

A vision for transparent, accessible compliance — nationwide

Codecheck exists to close the gap between the ordinance text and the field team — so that every contractor, architect, and developer operates with the same information that inspectors have always had.

Vision

A construction industry where no project stalls because of an unanswered code question

We believe that access to municipal code information should be instant, precise, and free of ambiguity. Codecheck exists to make the knowledge gap between ordinance text and field execution disappear — starting with 10 states and expanding nationally in the U.S.

Mission

Make every compliance result cite its source — always, without exception

Our mission is to digitize, structure, and surface U.S. municipal ordinances so that project teams can get verified compliance answers in seconds, with citations back to the exact section of law. We never paraphrase. We never summarize and omit. Every result we return shows you exactly where the rule lives in the code — because that's what real compliance requires.

Coverage

480 jurisdictions live — and growing nationally

We started in Illinois. Our extraction methodology is designed to scale to any U.S. municipality. New jurisdictions are added every month.

Why cross-state code knowledge matters
Electrical gap: Indiana (NEC 2008) vs Nebraska & Wyoming (NEC 2023) — 15-year difference across neighboring states.
Plumbing split: Iowa, Nebraska, South Dakota use UPC. Illinois, Indiana, Kentucky, Missouri, Wyoming use IPC. Different venting rules.
No-code states: Kansas and Missouri have no mandatory statewide building code. Local adoption only — varies city by city.
Climate range: Zone 4A (Kentucky/Kansas) to Zone 7 (Jackson WY, −25°F design temp) — broadest range in any regional dataset.
